During the production and manufacturing of chemical substances such as ethylene and polyester, it is very easy to generate chemical wastewater, which has significant toxic side effects and cannot be dissolved. If corresponding solutions are not taken, it will cause significant environmental pollution to the natural environment and, more seriously, damage biodiversity. Therefore, in future work, relevant personnel must adopt effective environmental protection solutions for wastewater, in order to reduce the damage of chemical plant production wastewater to the indoor environment.

1. The generation pathways and characteristics of chemical production wastewater

1.1 Origin

The formation methods of chemical wastewater mainly include the following aspects:

(1) During the period of mining and transportation of chemical raw materials, it is very easy to cause the overflow of mining wastewater, which will cause chemical wastewater under the erosion of rainfall, thereby causing environmental pollution to the natural environment.

(2) Insufficient chemical changes result in the generation of waste.

(3) Waste generated due to adverse reactions.

(4) Cooling circulating water.

(5) Leakage caused by machine equipment or pipelines.

(6) During work, there were errors in operation, which resulted in a lot of wastewater overflowing.

1.2 Characteristics of Chemical Wastewater

Due to the fact that chemical engineering mainly uses organic chemistry to solve and produce each network resource, it has the characteristics of multiple production manufacturing, multiple raw materials, and multiple processing techniques.

Therefore, this determines the following characteristics of the production wastewater from chemical plants:

(1) The toxic side effects are quite significant, and the wastewater produced by chemical plants contains a lot of lead, cadmium, and other carcinogens, which can cause significant harm to human physical and mental health.

(2) The composition is quite complex and can lead to serious environmental pollution, especially in organic chemical wastewater. The composition is very complex, containing a lot of acids, alcohols, etc., which can cause significant environmental pollution to the natural environment.

(3) There is a lot of oil in wastewater, which makes it difficult to solve chemical wastewater in work.

(4) Water is difficult to remediate after being polluted by the environment. For example, when mercury melts into the water, it can cause environmental pollution to the substrate and cannot be removed yet. At the same time, mercury will continue to gradually transform into methylmercury, further causing environmental pollution to the water.

2. Environmental protection treatment methods for chemical wastewater

2.1 Physical Solution Analysis Method

Among the technical aspects of chemical wastewater treatment, the physical disposal method is often used. It mainly uses physical practical effects to remove dirt that is difficult to dissolve in chemical wastewater, such as floating oil, oil droplets, etc. The methods solved by physics are further subdivided into various methods, such as filtration, ion exchange, vapor flotation, etc. The key facilities used in the filtration method include a frame filter press and its microporous filter. Generally speaking, microporous plate tubes are mainly formed by butadiene, and the diameter can be conveniently adjusted, which can successfully filter wastewater pollutants. The force ion exchange method uses the sedimentation ability of floating particles in wastewater, which is generated by the downward movement of the force. After the sedimentation reaches a certain level, it can generate the condition of solid-liquid separation equipment, thus completing the solution of wastewater. In addition, the vapor flotation method mainly uses bubbles with adsorption power to adsorb particles floating in wastewater, and then remove dirt from the river surface. Among the technical aspects of physical and chemical solutions, gas processing technology is not complicated and the management method is very simple, so it is widely used in the treatment of chemical wastewater. However, due to the inability to carry out comprehensive solutions, this method cannot be applied to the processing and treatment of soluble wastewater, as well as more difficult wastewater treatment work. Therefore, this method has significant limitations.

2.2 Organic Chemistry Solution Analysis Method

The organic chemical treatment method is often applied in the treatment of production wastewater in chemical plants. It mainly involves adding chemicals into the wastewater to generate chemical changes and their convective heat transfer reactions, so as to have the actual effect of separation. This method can comprehensively remove pollutants that can be dissolved in chemical wastewater, while also ensuring that the discharge of wastewater does not cause damage to the natural environment and human health. Organic chemical treatment methods also have various technical aspects, including air oxidation method, electrochemical analysis air oxidation method, and organic chemical concrete method. If it is to remove small suspended solids in wastewater, it is best to use organic chemical concrete method. Its main purpose is to add organic chemical drugs to the wastewater, allowing the small suspended solids to coagulate. This way, chemical substances can be stably deposited at the bottom of the machine equipment, and satisfactory industrial wastewater treatment results can be obtained.

Generally speaking, if the floating particle size in wastewater is between 1.0-10mm, it is best to use organic chemical concrete method. This method can not only effectively remove particles, but also remove the saturation of wastewater. Some microbial strains and organic compounds are easily affected by factors such as water body and temperature. Therefore, the actual effect of solving organic compounds with certain solubility is not ideal. Therefore, it is best to use organic chemical air oxidation method to remove this substance. The key form is to add oxides into the chemical wastewater, which can remove organic compounds and dirt from the wastewater. After obtaining the oxidation-reduction reaction, chemical wastewater can meet the corresponding standards, and toxic chemicals in both organic and inorganic compounds in the water can be transformed into water without harmful substances or with relatively small harmful substances. This way, the treatment of chemical plant production wastewater can be successfully carried out. In addition, the air oxidation method also includes oxidation, aluminum anodizing, and other methods. With the development trend in recent years, a completely upgraded oxidation-reduction reaction method for motor raw materials has been developed on the basis of the original technology, further enhancing the practical effect of solving industrial wastewater in chemical plants. We firmly believe that in the near future, we will continue to develop a large number of technical products related to chemical solutions.

2.3 Analysis of Technical Indicators for Microbial Solutions

In the processing and treatment of production wastewater in chemical plants, the use of microbial method has very good energy-saving and environmental protection practical effects. It mainly utilizes the new urban metabolism possessed by microorganisms to convert substances in wastewater. The microbial treatment methods mainly include two technical aspects, namely aerobic and reactive oxygen species solutions. At the same time, the previous method can also differentiate survival sludge and biofilm, while the active sludge method mainly uses microbial flocs floating in wastewater to achieve the actual effect of solving the problem. This method mainly combines aerobic microbial strains and their basic metabolism with and without maintenance, so as to convert organic pollutants in wastewater. The biofilm rule is based on the actual adhesion and air oxidation effects of the biofilm system to combine wastewater with the biofilm system, thereby removing organic compounds from the production wastewater of chemical plants.

In the absence of molecular structure oxygen, anaerobic biological solutions can be used, mainly by using anaerobic fermentation microbial strains to convert organic compounds in chemical wastewater into carbon dioxide. This can achieve the actual effect of removing organic compounds and improving environmental protection quality. It belongs to a relatively complex cellular biology process, and its most significant advantages depend on low cost, easy practical operation, and because microbial solution processes require high-quality nutrients, water, etc., it is not suitable for solving chemical wastewater with strong toxic side effects and difficult to dissolve.

2.4 Analysis of Deep Solutions

According to the degree of resolution, the technical aspects of deep level solutions can be divided into first level, second level, and third level solutions.

First level solution: It can remove environmental pollutants with floating patterns in wastewater. In physical and chemical solutions, only the actual effect of first level solution can be achieved. After first level solution, the BOD in wastewater can usually be reduced by 30%, but it cannot meet the main requirements for consumption. Therefore, this solution work mainly lays the foundation for second level solution.

Secondary solution: It can remove organic pollutants that have a melting state in wastewater, and after secondary solution, the BOD in wastewater can be reduced by more than 90%, thereby meeting the discharge standards for organic chemical pollutants.

Third level solution: It can comprehensively remove organic compounds that are difficult to decompose. Mainly using biological denitrification analysis methods, coagulation precipitation method, activated carbon adsorption method, ion exchange, etc.

Because the chemical industry has achieved good development trends over the years, a large amount of wastewater is generated in the production process, and its chemical composition is also more complex. If wastewater can be effectively removed, it can not only improve the ecological environment, but also enable chemical plants to achieve good development trends. In addition, for relevant personnel, it is necessary to design effective treatment methods based on the actual situation of wastewater treatment, so as to achieve the desired practical results in chemical wastewater treatment work. Over the years, there has been some improvement in the solution of chemical wastewater in China, and scientific research is still being carried out on the application of new technologies. After the announcement of its application, it is certain to further strengthen the ability to solve production wastewater in chemical plants. However, the relevant staff should not only reach the current level, but also understand that there are still some difficult problems to solve in the current work of solving production wastewater in chemical plants. Therefore, during the operation period, it is necessary to be diligent in thinking and further improve the level of solving production wastewater in chemical plants, so as to ensure the ecological environment of China.

3. Effective management measures for chemical wastewater

3.1 Reasonable Layout of Chemical Enterprises

Chemical enterprise management personnel should establish sound rules and regulations for the treatment of chemical production wastewater, and use effective methods to reduce the wastewater generated during the chemical production and manufacturing period. Moreover, relevant staff also need to strengthen the establishment of public supporting facilities and carry out scientific and reasonable layout of production, manufacturing, and rest rooms. During the period of solving chemical production wastewater, priority should be given to areas with severe environmental pollution. The company also needs to collaborate with government departments in the city to introduce professional wastewater removal machinery and equipment, and recycle and reuse a portion of the wastewater, which can save the company's operating costs.

3.2 Terminal solution of chemical wastewater

Nowadays, many chemical companies in China are unable to completely remove chemical wastewater due to factors such as assets and technology, resulting in the occurrence of many harmful substances during the wastewater discharge period. Therefore, in order to better enhance the practical effectiveness of wastewater treatment, it is necessary to digest and absorb the recent technical and work experience of excellent countries, and apply clean production technology. The fundamental reason for choosing this technology is that it does not require a significant amount of assets during the wastewater treatment period and can achieve good practical results. In addition, during the period of chemical production and manufacturing, it is best to choose raw materials that are not prone to significant pollution, so as to significantly reduce the amount of chemical production wastewater and achieve practical environmental protection effects.

Based on the above content, everyone can recognize that due to the development trend in the chemical industry, the amount of chemical wastewater is gradually increasing, and the composition is also becoming more complex. If reasonable and effective solutions cannot be carried out, it will definitely cause significant environmental pollution to China's natural environment. And this requires relevant personnel to scientifically and reasonably utilize environmental protection solutions for chemical wastewater in their future work, and to carry out scientific and reasonable layout and tail end solution work for chemical companies. This can ensure the actual effect of solving chemical production wastewater and improve China's ecological environment.
