The production process and technology of electroplating production enterprises are quite different, and the production wastewater of each enterprise is diverse and the water quality varies greatly. However, the existing electroplating wastewater treatment system mainly mixes various types of wastewater and directly enters the comprehensive wastewater treatment system. There is no Classify and treat the types of electroplating wastewater from the source, so that it is impossible to formulate treatment strategies for different wastewater, resulting in low quality wastewater treatment and affecting the final wastewater treatment effect; moreover, the existing treatment system only uses network breaking reaction and precipitation treatment, It is difficult to carry out advanced treatment of electroplating wastewater treatment projects with large water quality and water volume, and the treatment effect is poor

Abstract
The invention relates to the field of wastewater treatment, and discloses an advanced treatment system for electroplating wastewater, which comprises a physical and chemical treatment system, a biochemical treatment system, a recycling system and a sludge treatment system. The physical and chemical treatment system comprises a primary treatment system, an intermediate water tank, a secondary treatment system and a buffer tank which are sequentially connected through pipelines. The buffer tank is connected with the biochemical treatment system through a pipeline, the biochemical treatment system is connected with the recycling system through a pipeline, and the primary treatment system, the secondary treatment system, the biochemical treatment system and the recycling system are all connected with the sludge treatment system. According to the advanced treatment system for electroplating wastewater, the electroplating wastewater is classified, collected and treated from the source, and the electroplating wastewater of different types is deeply treated through a multi-stage physicochemical treatment and biochemical treatment process, so that the treatment efficiency is improved, and the treatment effect is improved.
Description
technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to an advanced treatment system for electroplating wastewater. Background technique [0002] The electroplating industry is an important processing industry in my country, but it is also one of the three major polluting industries in the world. Electroplating production consumes a large amount of process water and produces a large amount of wastewater. The wastewater generated during the production process may contain chromium, nickel, copper, and cadmium. , zinc and other heavy metals, as well as toxic and harmful pollutants such as cyanide, acid and alkali, brighteners, additives, etc. It has the characteristics of complex composition, difficult to handle, strong toxicity, and great harm. Its pollution control is highly valued by environmental protection departments at all levels . [0003] The existing notification number CN110117107A and the Chinese invention patent ...
