What are the core technologies of surface treatment wastewater treatment process?

　　For zero discharge of surface treatment wastewater, it is generally understood that harmful substances in wastewater should be removed or reduced to a minimum to protect the environment and human health. This is also the goal that many industrial enterprises want to achieve, taking into account both corporate development and environmental protection. What are the core technologies of surface treatment wastewater treatment process? In general, there are four core technologies:

　　1. High-precision heavy metal removal pretreatment technology

　　Technical principle: Accurately remove heavy metal ions from wastewater by adopting efficient chemical precipitation and electrochemical technology, ensuring the efficiency and stability of subsequent treatment links.

　　Innovation highlights: By adjusting chemical agents and electrochemical parameters, it is possible to optimize treatment according to different wastewater characteristics, achieving higher removal efficiency and lower treatment costs.

　　2. OSMMBR biochemical technology

　　Technical principle: Achieve deep degradation of organic pollutants and wastewater purification through the optimized membrane bioreactor (MBR) combined with efficient oxidation process.

　　Innovation highlights: Improve the treatment efficiency by adopting advanced oxidation technology, reduce membrane pollution, extend membrane service life and reduce maintenance costs.

　　3. SPNR technology

　　Technical principle: A new type of physical-chemical combined treatment technology that removes suspended matter and dissolved organic matter in water through specially designed reactors.

　　Innovation highlights: Efficiently remove particulate matter and soluble pollutants in wastewater, ensure that treated wastewater can be directly reused, thus reducing the water costs of enterprises.

　　4.MVR crystallization technology

　　Technical principle: Concentrate and crystallize wastewater, precipitate soluble metal ions by adopting mechanical vapor recompression (MVR) technology, and achieve resource recovery.

　　Innovation highlights: Compared with traditional evaporation crystallization technology, MVR technology has lower energy consumption, lower operating costs and higher metal recovery rate, and can reduce the generation of solid waste.

　　Nowadays, the above are the four core technologies of surface treatment wastewater treatment process. Through the combination of multiple core technologies, a better treatment effect can be achieved. Moreover, each one has corresponding innovative highlights, which can reduce the cost and improve the efficiency of wastewater treatment for enterprises.
