In view of the diverse pollutants present in the production wastewater of electronic factory, achieving effective treatment via a singular method is challenging. Using an electronic factory in Zhejiang Province as a case study, this paper designs a multi-stage treatment system to treat the production wastewater, aiming to achieve zero discharge of acid-base heavy metals. The multi-stage treatment system designed in this paper comprises an alkali washing wastewater treatment system, acid washing wastewater treatment system, nickel-containing wastewater membrane separation system, membrane reuse system and evaporative crystallization system. The system utilizes special silicon carbide ceramic membranes for oil-water separation, improving its efficiency in reducing emulsified oil and COD. The experimental results demonstrate that the pH, COD, ammonia nitrogen, total nitrogen, total nickel and conductivity indexes of the treated wastewater meet the requirements, and can be directly reused as pure water in the production line, thereby facilitating water resource recycling and promoting ecological environmental protection. The research results can provide reference and guidance for the comprehensive sewage treatment in the fine chemical industry park.
