In the production process of electronic semiconductors, heavy metal wastewater and cleaning sewage will be generated, and the direct discharge of these wastewater will cause certain pollution to the surrounding environment. In the whole process of production, manufacturing and recycling of electronic products and related metal products, a large amount of electronic wastewater is caused. The composition of electronic wastewater is different, and the types and contents of pollutants contained in it are also different, in which the basis is chromium, copper, nickel, cadmium, zinc, lead, mercury and other heavy metal ions lithium ions, cyanide, some acidic substances and alkaline substances. The heavy metal ions in wastewater have the characteristics of long toxicity, non-biodegradation, etc., and can be enriched in organisms, causing biological dysfunction and causing serious harm to the ecological environment and human health. Therefore, for the treatment of electronic semiconductor wastewater, it is necessary to build an electronic semiconductor wastewater treatment system project with targeted needs according to the specific situation of each production enterprise and the discharge standards of local industrial wastewater, so as to ensure the efficient and stable operation of the wastewater treatment station after completion.
