Problems solved by technology

Coagulation, chemical oxidation, adsorption and other physical and chemical technologies in the treatment of dye wastewater have problems such as high operating costs, high energy and chemical consumption, and secondary pollution. Traditional activated sludge and biofilm methods have limited effects in treating dye wastewater
At present, the dye wastewater treatment process combined by physical and chemical methods and traditional biochemical methods often has a long process, and the investment and operation costs are quite high.

Abstract

A biologic method for treating the reactive dye sewage with white rot fungus membrane includes such steps as adding the white rot fungus into biochemical filler treating region, starting aerator for supplying oxygen, filling said sewage in the region, passing through steel wire mesh and into membrane region, and pumping the cleaned water to water outlet pipe via hollow fiber membrane.

Description

technical field [0001] The patent of the present invention relates to a method and device for treating reactive dye wastewater by white rot fungal membrane biological method, which belongs to the technical field of environmental engineering and can be applied in the treatment of reactive dye wastewater. Background technique [0002] Dye wastewater discharged from dye chemical factories has the characteristics of high chroma, high salinity, strong toxicity, high pollutant content and complex components, and is difficult to degrade. It is the focus and difficulty of industrial wastewater pollution control. Physicochemical technologies such as coagulation, chemical oxidation, and adsorption have problems such as high operating costs, high energy and chemical consumption, and secondary pollution when treating dye wastewater. Traditional activated sludge and biofilm methods have limited effects in treating dye wastewater. At present, the dye wastewater treatment process combined ...
