One of production wastewater 1. Treatment method for industrial wastewater 1 of industrial wastewater treatment method is a method for treating industrial wastewater, belonging to the field of wastewater treatment technology. It is to divert the sewage to the collection tank, adjust the pH at the end of the collection tank, use a first stage dissolved air pump to lift it to the first stage pressure dissolved air tank, while inhaling air and coagulation decolorizing agent, and suddenly release the first stage saturated dissolved air water in the first stage pressure dissolved air tank to the first stage air flotation tank to form the first stage treated water; The first stage treated water overflows into the buffer tank, and then the pH is controlled by using a second stage dissolved air pump to lift the first stage treated water into the second stage pressure dissolved air tank. At the same time, air and coagulation decolorizing agent are sucked in, and the second stage saturated dissolved air water in the second stage pressure dissolved air tank is suddenly released into the second stage air flotation tank to form the second stage treated water, which overflows to the sedimentation tank for sedimentation before being discharged; The floating mud in the first and second stage air flotation tanks enters the floating mud tank, is filtered into a filter cake, and the filtrate is returned to the collection tank. The CODcr, decolorization rate, SS, and BOD5 removal rates of industrial wastewater treated by this method are 80-90%, 95%, over 90%, and 75-80%, respectively, which comply with the first level water discharge standard of GB8978-1996. Biogas power generation is a new energy comprehensive utilization technology that integrates environmental protection and energy conservation. It utilizes the biogas produced by anaerobic fermentation treatment of industrial wastewater to drive a biogas generator set for power generation, and can fully utilize the waste heat of the generator set for biogas production, achieving a comprehensive thermal efficiency of about 80%, which is much higher than the general 30-40% power generation efficiency. The significant economic benefits for users are a good method for treating industrial wastewater. A kind of industrial sewage processing method, belonging to the technical field of sewage treatment. The sewage which leads to the sump for collecting tank, at the end of a regulator of pH, with a dissolved air pump to a pressure air dissolving tank, at the same time of inhaled air and coagulation decolourant, will be at the level of pressure dissolved air tank level within the saturated dissolved air water suddenly released into a flotation tank form a level of processing water; a water spill into the buffer pool, and then in the control of pH two gas dissolved water pump level water level to the two pressure dissolved air tank, at the same time of inhaled air and coagulation decolourant, two stage pressure dissolved air tank two level within the saturated dissolved air water suddenly released into the two stage flotation tank to form the two stage of processing water and overflow to the sedimentation tank for sedimentation after discharge; one or two level in the flotation tank floating mud into the mud pool, filter into cake, leachate to lead to water collecting tank. The method for processing
