Description
Technical Field
The utility model belongs to the technical field of the chromium pollutant, concretely relates to draw hydrocyclone separator for technology of chromium in chromium pollutant.
Background
The chromium salt industry is an indispensable important industry in national economy and is mainly used for aspects of electroplating, tanning, printing and dyeing, medicines, catalysts, metal corrosion inhibition and the like. The main waste residue discharged in the production process of chromium salt (i.e. chromium slag) is a dangerous waste with high toxicity, wherein Cr is6+Is the source of toxicity. According to the analysis result of the chemical composition characteristics of partial chromium slag in China, the average content of total chromium in the chromium slag is about 3-5 percent, and the average content of hexavalent chromium is about 1-5 percent (all by Cr)2O3Meter). The chromium slag contains six components including Cr6+Sodium chromate tetrahydrate, calcium chromate aluminate and basic ferric chromate, calcium silicate-calcium chromate solid solution and calcium aluminoferrite-calcium chromate solid solution, respectively. Wherein the tetrahydrate sodium chromateAnd free calcium chromate is a water-soluble phase and is easily dissolved by surface water and rainwater; the other four components are difficult to dissolve in water, but are easy to cause medium and long-term environmental pollution caused by the chromium slag through weathering and hydration in the long-term open-air storage process.
The prior chromium slag detoxification method comprises the steps of separating chromium slag from waste water, reducing hexavalent chromium in the chromium slag into trivalent chromium, solidifying the trivalent chromium in waste slag, and then safely burying the waste slag.
