How to ensure zero discharge of wastewater from electroplating plants for environmental protection? Regarding the issue of industrial production wastewater treatment, we firmly believe that many industrial production manufacturing and processing companies have been facing the main problem. How to effectively and reasonably treat wastewater is a necessary prerequisite for companies to consider in the production process. Today, the editor will share with you how to achieve environmentally friendly zero discharge treatment of electroplating plant wastewater.

The technical solution for zero discharge of wastewater should be selected based on the production and manufacturing characteristics of the power plant. Due to the wide range of weak wastewater bodies in power plants, the use of power plant smoke and dust waste heat boilers is the future development trend of wastewater treatment technology, especially in the application of ultra-low temperature waste heat recovery, but there are still many problems. The vast majority of old power plants still use triple box machinery and equipment for pre-treatment technology, or carry out updates and renovations on current machinery and equipment; For newly created power plants, based on the characteristics of wastewater from different power plants, sometimes the pre-treatment stage can be omitted to reduce the investment and operating costs of wastewater treatment.

In order to better maintain the machinery and equipment of the sewage treatment station, some equipment and buildings should be laid out before a one-time solution. Because the effectiveness of restoring BOD5 based on this device and structure is particularly limited, this type of processing method is called preprocessing. According to the metabolism of microbial strains, organic pollutants in saturated solutions, colloidal solutions, and micro mixtures in wastewater are converted into stable and harmless chemicals. According to the different microbial strains, microbial solutions can be divided into aerobic microbial solutions and anaerobic biological treatments.

Because excessive heavy metals cannot be decomposed and destroyed, they can only migrate their parts, change their physical and organic chemical shapes, in order to achieve the goal of removing excessive heavy metals. For example, in the entire process of wastewater treatment, after being solved by chemical precipitation, the excessive heavy metals in the wastewater change from the shape of dissolved positive ions to insoluble chemicals and precipitates, which migrate from water to sludge; After being solved by ion exchange method, heavy metal ions in the wastewater are transferred to the ion exchange column, and then transferred to the regenerated wastewater through ion exchange resin regeneration.

Zero emission technology is only an idealized situation within the scope of people's work ability, and it is unlikely to independently achieve zero emissions in a certain field or industry. It involves many courses and industries. Only by cooperating and striving together in various industries can we achieve zero emissions and benefit humanity.
