Abstract

The invention discloses a coagulant which is used for purifying printing and dyeing wastewater and treating the printing and dyeing wastewater and belongs to the technical field of environmental science protection. The coagulant comprises 10-40% of blast furnace slag by weight, 50-70% of carbide slag by weight and 10-20% of fly ash. According to the coagulant for purifying the printing and dyeing wastewater, the source is convenient, waste is treated with waste, the waste is changed into wealth, and the coagulant has a good coagulation effect, is quick in precipitation adsorption and has very high removal rate for various wastewater and pollution components.

Description

technical field [0001] The invention belongs to the technical field of environmental protection. Specifically, it relates to an inorganic agent for condensation of printing and dyeing wastewater. Background technique [0002] Before the present invention was made, there were many kinds of coagulants used for printing and dyeing wastewater treatment in the prior art, such as basic aluminum chloride, aluminum sulfate, ferrous sulfate and other inorganic coagulants, which had poor decolorization effect and unstable treatment effect on printing and dyeing wastewater , cannot effectively remove the color of printing and dyeing wastewater. Contents of the invention [0003] The coacervate proposed by the present invention can avoid the above disadvantages. The present invention aims to produce a coagulant with convenient source of raw materials, low price, fast coagulation, adsorption and precipitation, and good sludge depermanence performance for purifying printing and dyeing ...
