In recent years, the development plan of China's traditional Chinese medicine industry has been very fast. However, with the development plan of key industries, the wastewater discharged by the company has also become one of the natural environmental pollutants. According to the investigation, traditional Chinese medicine companies cause a lot of wastewater during the entire process of raw material cleaning, drug acquisition, and cleaning. In terms of wastewater treatment, the treatment of wastewater from traditional Chinese medicine production and manufacturing is one of the most important goals of remediation.

The key source of traditional Chinese medicine wastewater comes from the assembly workshop, which is generated during the entire process of washing, steaming, cleaning, and preparing traditional Chinese medicine. Wastewater includes raw material cleaning water during the processing, raw material juice waste liquid, filtration, steam distillation, purification and other modules that cause wastewater during actual operations, production line equipment cleaning, and wooden floor cleaning tap water. The key to air pollutants is the various components extracted from traditional Chinese medicine, including glycogen, Huixing, lignocellulose, alkaloids, proteins, melanin, and their hydrolysis reaction substances. The characteristics of traditional Chinese medicine wastewater are: high concentration of organic chemical air pollutants; Suspended solids, especially organic chemical substances such as lignocellulose with a relatively light proportion and unable to settle, have a high water content; High saturation; The biodegradability of sewage is good; Intermittent discharge is common, and the composition of sewage is complex, resulting in significant changes in water flow rate.

What is the moisture content of wastewater in the production of traditional Chinese medicine industry chain

Traditional Chinese medicine chemical wastewater generally belongs to one of the difficult to solve high concentration organic chemical wastewater, which varies greatly due to different drug products and production processes. Traditional Chinese medicine wastewater generally has a complex composition, multiple types of organic chemical air pollutants, high concentration values, high and uncertain CODCr and BOD5 values, significant differences in BOD5/CODCr values, high NH3-N concentration values, deep saturation, significant toxic side effects, and high SS concentration values in solid suspended solids.

The water body of traditional Chinese medicine production wastewater has great uncertainty, with COD reaching 6000mg/L and BOD reaching 2500mg/L, and the key contains pure natural organic chemical substances. The wastewater from the production of traditional Chinese medicine formulas contains various pure natural organic chemical air pollutants, such as glycogen, anthraquinone, alkaloids, proteins, melanin, lignocellulose, and their hydrolysis reaction substances. The key components of sewage include residues of traditional Chinese medicine, methyl cellulose, hemicellulose, brittle macroporous resin, solvents (alcohol), glycosides, anthraquinone, alkaloids, and hydrolysis reaction substances.

Selection of Software Processing Technology for Traditional Chinese Medicine Wastewater Treatment Plan System

The comprehensive traditional Chinese medicine wastewater treatment plan system software includes three stages: preliminary treatment, microbial solution, and organic chemical post-treatment process. Because sewage contains a lot of solid chemicals, organic matter, etc., it mainly exhibits high levels of CODCr, SS, etc. Due to the characteristics of wastewater and its good biochemical properties, as well as the presence of small amounts of nutrients such as N and P for microbial growth and reproduction, choosing microbial processes for treatment is the most reasonable and economically viable solution. For the left and right conditions, our company plans to use the ABR+contact air oxidation composition process for treatment.

1) Because the wastewater from the processing plant contains a large amount of suspended solids, it is necessary to install one grid of different sizes in the sewage ditch to remove the coarse suspended solids in the wastewater and ensure the normal operation of all subsequent solutions.

2) Because the amount of wastewater generated by the production and manufacturing of processing plants fluctuates greatly over time, it will not be conducive to solving the problem of microbial strains afterwards. Therefore, a horizontal sedimentation tank is lifted before the integrated solution machine equipment, and then lifted into the integrated solution machine equipment through a centrifugal water pump.

3) After the sewage is lifted by the sewage lift pump and fed into the integrated machine equipment, it is distributed through the water distribution system and then enters the dosing air flotation area of the integrated machine equipment. The small SS and the vast majority of LAS in the sewage are reasonably removed, and then the sewage enters the hydrolysis reaction area. Here, the biological macromolecular organic compounds in the sewage are hydrolyzed and reacted into small molecule hydrochemicals, which will be beneficial for the use of organic compounds by microbial strains.

4) Due to the high COD of wastewater after undergoing necessary diluents, anaerobic fermentation is necessary to ensure that the wastewater meets the discharge standards. According to anaerobic tanks, the saturation of sewage can be reduced. Anaerobic fermentation solution is a stable and harmless method of dissolving organic compounds under anaerobic exercise standards, with anaerobic fermentation microbial strains as the main driving force. In anaerobic fermentation microbial treatment, complex organic matter is dissolved, converted into concise and stable chemical substances, and kinetic energy is released (mostly in the form of CH4). A small amount of organic compounds are converted into new somatic structures, resulting in a small annual growth rate of sludge. Compared to the commonly used anaerobic reactors at present, the application status and fields of anaerobic fermentation sludge reaction bed (UASB), anaerobic fermentation inclined plate sedimentation tank (AF), anaerobic fermentation touch air oxidation method, and anaerobic fermentation composite bed tube reactor (UBF) in the upstream flow type, combined with the characteristics of this wastewater and our company's engineering project work experience, people have selected anaerobic fermentation baffle reaction biofilter (ABR) as the anaerobic fermentation process treatment for this project.

This processing technology is a complex and complex hydroelectric power generation flow anaerobic fermentation process for treatment. The anaerobic fermentation microbial strains in different compartments of the tubular reactor exhibit excellent characteristics, and the re capture method is widely used and cooperates to solve the problem. The growth and development of microbial strains in different compartments are integrated into the sewage water body injected into the compartment, which is beneficial for producing excellent microbial strain system software. The room by room transformation of this type of microbial strain marker recapture method enables the dominant population to grow and develop well, and gradually converts air pollutants in wastewater, achieving stable dissolution under the efficacy of each responsible microbial strain marker recapture method. The strong impact load resistance of ABR comes from its strong ability to intercept the solid state in wastewater and the effective spread of microbial species identification and re capture methods. This processing technology is applicable to a variety of natural environmental standards (water and temperature), and can operate smoothly within a temperature range of 10-55 ℃.

5) After going through the anaerobic fermentation zone, the sewage enters the biochemical aerobic zone.

Due to the high COD content in wastewater and the full consideration of the load-bearing capacity of microbial strains, cold water flow back is selected for the front-end development of the touch air oxidation method to dilute the source water by 1-3 times. Touch air oxidation method is a new biochemical solution for wastewater that combines the characteristics of activated sludge method and extracellular matrix method. In the hydrolysis acidification tank with poor breathability, filling material is equipped. The filling material is submerged in water, and a blower motor is used to add oxygen to the hydrolysis acidification tank at the bottom of the filling material; The air energy water heater brings in the sewage waiting for review from top to bottom, and a portion of it reaches the road surface according to the filter material. After the gas escapes, the sewage returns to the water tank from top to bottom in the filter material compartment. The activated sludge method is attached to the surface of the filling material and does not flow with water. As the extracellular matrix is immediately subjected to significant stirring by an elevated cyclone, continuous innovation has been made, thereby improving the actual cleaning effect. The microbial contact air oxidation method has the advantages of fast solving speed, light weight, easy cleaning and use, good and stable water output, no need for sludge to flow back and no swelling, and low power consumption. Therefore, integrating the water body and water flow characteristics of this engineering project, people choose the touch air oxidation method to solve the problem.

Characteristics of touch air oxidation method:

(1) High capacity load, strong anti impact load working ability;

(2) Having the advantage of membrane method, the remaining amount of sludge is small;

(3) Having the advantages of activated sludge method, high microbial specificity, and short sludge age;

(4) Can dissolve other microorganisms to solve difficult to dissolve chemical substances;

(5) It is very easy to manage methods, but there are drawbacks such as clearing silt, raising water levels, and swelling.

(6) After going through the biochemical aerobic zone, the sewage enters the settling area of the integrated machinery and equipment, and then the sludge in the sewage is settled before being discharged.

Technical Treatment of Yingyuan Wastewater Treatment Difficulties in Traditional Chinese Medicine Industry Chain Wastewater Treatment

The selection of Yingyuan wastewater treatment technology can effectively handle the difficulties in traditional Chinese medicine industry chain wastewater treatment. The flexible use of MBR production process in traditional Chinese medicine wastewater treatment is a new type of wastewater solution and recycling processing technology that integrates degradation efficiency and membrane separation technology. The membrane filtration water output is obtained based on the air pressure pumping effect of the processing pump. In order to enhance the practical effectiveness of biochemical solutions for wastewater, the oxygen deficient section should be elevated before MBR, and the solution (nitrate) from the aerobic section should be returned to the oxygen deficient section, thereby further improving the practical effectiveness of microbial solutions. Exceeding the first level standard of the Comprehensive Environmental Protection Standard for Wastewater (GB 8978-1996) for sewage discharge.

Regarding the treatment of traditional Chinese medicine wastewater, the treatment of wastewater in the traditional Chinese medicine industry chain is one of the top priority goals. For the traditional Chinese medicine industry chain, it is necessary to keep up with the times and apply new technologies more effectively in the treatment of wastewater in the traditional Chinese medicine industry chain. Ensuring that organic chemical air pollutants in water have comprehensive utilization value and converting this wastewater into high-quality green energy with modern utilization value is one of the key treatment concepts.
