Description

A kind of compound for treatment of electroplating wastes

Technical field

The present invention relates to water-treatment technology field, specifically a kind of compound for treatment of electroplating wastes.

Background technology

There are plating piece rinse water, spent plating bath and other waste water in the source of electroplating wastewater.The water quality of electroplating wastewater, the water yield and the processing condition of Electroplating Production, the factors such as load, operational administrative and water use model of producing are relevant.The water quality of electroplating wastewater is complicated, and composition is wayward, and wherein containing heavy metal ion and prussiates etc. such as chromium, good fortune, nickel, copper, zinc, gold and silver, waste component is complicated.

The method for comprehensively treating waste liquid that current electroplating wastewater adopts has a lot, as chemical method, ion exchange method, electroosmose process, electrolytic process etc., wherein chemical method is the method comparatively commonly used, it adds reductive agent (as ferrous sulfate, iron powder etc.) in containing the waste water of hexavalent chromium, after hexavalent chrome reduction is become trivalent chromium, add waste water conditioner sodium hydroxide, the pH value of adjustment waste water, heavy metal ion in fractionation precipitation waste water, finally also needs could be discharged by the supernatant liquor pH value of acid adding adjustment after precipitation.Adopt such waste water conditioner process electroplating wastewater, there is the shortcoming that raw material dosage is large, sewage treatment technology process long, occupation of land is many, energy consumption large, operational management difficulty is large, labor strength is large and running cost is high, but also can not ensure that wastewater treatment stably runs.

Therefore, need provide a kind of and reduce processing cost, treatment effect stablizes and the compound for treatment of electroplating wastes of non-secondary pollution.

Summary of the invention

The object of the present invention is to provide a kind of compound for treatment of electroplating wastes, to solve the problem proposed in above-mentioned background technology.
