Abstract

The invention provides an electroplating waste water zero discharge system and relates to the technical field of sewage treatment. The bottoms of a nickel-containing waste water regulating pool, a nickel-containing waste water PH regulating pool, a nickel-containing waste water buffer pool, a nickel-containing waste water coagulating pool, a nickel-containing waste water flocculating pool and a nickel-containing waste water settling pool are connected with a nickel-containing sludge concentration pool through pipelines; the nickel-containing sludge concentration pool is connected with a nickel-containing sludge compressor; concentrated liquid in the nickel-containing sludge compressor is connected with the nickel-containing waste water regulating pool through a pipeline; a phosphorus-containing waste water regulating pool, a phosphorus-containing waste water PH regulating pool, a phosphorus-containing waste water reaction pool, a phosphorus-containing waste water coagulating pool, a phosphorus-containing waste water flocculating pool and a phosphorus-containing waste water settling pool are connected through pipelines. The electroplating waste water zero discharge system is high inremoval rate of pollutants and stable to operate, reasonably utilizes an advanced membrane technology, reduces membrane blockage, guarantees the service life of the membrane, increases the water production rate of the membrane, can reduce evaporation cost and has higher practicability.

Description

Technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a zero discharge system for electroplating wastewater. Background technique [0002] With water shortages and serious environmental pollution today, in order to alleviate the contradiction between water supply and demand and curb the deterioration of the water environment, it is necessary to improve water use efficiency, reduce pollutant emissions, and achieve zero emissions as much as possible. However, due to the high concentration of wastewater pollutants and the various types of pollution, the zero discharge effect of wastewater is not good, the volume of concentrated water is large, the membrane fouling is serious, the initial investment is large, the operating cost is high, and the treatment effect is poor, and it is urgent to improve. Summary of the invention [0003] The purpose of the present invention is to aim at the defects and deficiencies of the prior art to prov...
