Electroplating reclaimed water recycling and treating system

Abstract

The invention relates to an electroplating reclaimed water recycling and treating system, comprising a control device, a preposed adjusting system, an ultrafiltering treating system and a reverse osmosis treating system, wherein the preposed adjusting system, the ultrafiltering treating system and the reverse osmosis treating system are mutually communicated, the preposed adjusting system comprises an ORP (Oxidation-Reduction Potential) adjusting system and a PH adjusting device; the ORP adjusting system comprises an ORP adjusting tank, a reducing agent metering pump, a reducing agent tank and a stirrer; the ulatrafiltering system comprises a water pump, a quartz sand filter, a precise filter and an ultrafiltering membrane assembly; and the reverse osmosis system comprises a water pump, an active carbon filter, a scale inhibitor adding device, a safety filter, a first section of high-pressure pump, a second section of high-pressure pump, a reverse osmosis membrane assembly and a water purified tank. By adopting a device combining membrane separation and the filter to treat the electroplating reclaimed water, the invention has the advantages of favorable treatment effect, low operation cost, convenient operation and capability of long-term continuous operation; and in addition, the invention meets the requirements of environmental protection and cleaning electroplating, not only reduces the pollution and saves the production cost, but also can fully utilize water resources and protect the environment.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to an electroplating water reuse treatment system that treats electroplating wastewater and reuses it in production to make full use of water resources. Background technique [0002] The electroplating cleaning water in the electroplating factory contains a lot of heavy metal ions. If it is discharged without treatment or the treatment is not up to standard, the wastewater will pollute the water source and the environment, which will not only endanger human health, but also cause the deterioration of the ecological environment. On the other hand, electroplating wastewater contains valuable substances such as precious metals or heavy metals. If recycled, it can not only reduce pollution, but also reduce production costs and save water resources. [0003] At present, the existing electroplating wastewater treatment devices generally add various chemical agents to the wastewater, and adj...

AI Technical Summary

Problems solved by technology

This kind of treatment process cannot recover valuable substances such as precious metals in wastewater, and the water quality after treatment is unstable, and heavy metal substances are prone to exceed the standard. If the sludge containing heavy metals is not properly treated, it may cause secondary pollution.
