Abstract

The invention relates to a steel wastewater treatment system. According to the steel wastewater treatment system, the output end of a rough grain separator is connected with the input end of an electromagnetic coagulator, the output end of the electromagnetic coagulator is connected with the input end of an inclined plate deposition tank, the output end of the inclined plate deposition tank is connected with the input end of a hot water tank, the output end of the hot water tank is connected with the input end of a cooling tower, the output end of the cooling tower is connected with the input end of a cold water tank, the output end of the cold water tank is connected with the input end of a filter, and the output end of the filter is connected with the input end of a rotary furnace. By adopting the steel wastewater treatment system, the problem of wastewater pollution of steel companies can be solved, and the water can be saved.

Description

technical field [0001] The invention relates to a steel wastewater treatment system. Background technique [0002] The iron and steel industry consumes a lot of water, usually 4-10 tons of water per ton of steel, and the wastewater discharged during the production process mainly comes from the production process water, circulating cooling water for equipment and products, cleaning water for equipment and sites, etc. [0003] In terms of production process, iron and steel wastewater mainly includes sintering, ironmaking, steelmaking, steel rolling (hot rolling, cold rolling), coking and other wastewater. Among them, in view of the characteristics of coking wastewater containing a large amount of phenol, cyanide, ammonia nitrogen, and organic pollutants, special physicochemical and biochemical treatments are generally carried out to meet the discharge standards; in view of the characteristics of cold rolling wastewater containing oil, acid-base, and emulsion, oil removal is ca...
