A method of treatment of industrial waste water, which belongs to the technical field of sewage treatment. It is to be led to the sewage sump, the sump of the end of a grid adjusting pH, dissolved air lift pump with level to level pressure dissolved gas cylinders, while the intake air and flocculating bleaching agent, the solution tank level pressure within a saturated dissolved air flotation water suddenly released into a pool of water forming a handle; a treated water overflows into the buffer pool, Dongguan industrial waste water, and then dissolved in controlling pH with two gas pumps treated water will be an upgrade to dissolve secondary pressure inside the tank, while the intake air and flocculating bleaching agent, the secondary pressure dissolved within two tank water saturated dissolved air flotation tank suddenly released into a secondary form of secondary treatment and self-overflow water to precipitate After sedimentation pond discharge; a floating pool of mud into the secondary flotation fluid mud pools and industrial waste water filtration, filter press into a cake, and the filtrate lead back to the sump. CODcr industrial wastewater treatment method, bleaching rate, SS, BOD5 removal rates of 80 to 90%, 95%, 90%, 75-80%, in line with GB8978-1996 level of water discharge standards. Biogas power generation is set environmental protection and energy saving in one of the energy utilization of new technologies. It uses industrial wastewater treatment and biogas produced by anaerobic fermentation, the driving gas turbine for power generation, and full use of waste heat generator sets for biogas production, so that the overall thermal efficiency of about 80%, much higher than the normal 30 to 40% of electricity generation efficiency, the economic benefits significantly is a good way to treat industrial wastewater. Guangzhou Fu students environmental Sihui City Southern city electroplating electroplating wastewater treatment projects focus: industrial sewage treatment works stand-alone debugging, unit testing, debugging subparagraph 1, stand-alone debugging (1) process design work alone operation equipment, non-standard devices are called stand-alone. Should be in the water-filled, for standalone debugging. (2) single commissioning the following procedure should be carried out. 2, unit commissioning (1) unit commissioning is designed for each process unit treatment carried out, such as the grill unit, adjust the pool unit, hydrolysis unit, aerobic unit, two sink units, air units, sludge thickening unit different requirements sludge dewatering unit, sludge return unit and the like performed. (2) unit debugging within a single device test base unit BU _ conducted because each. Unit may have several different devices and device component, unit test the devices within the inspection unit-linked operation, and should to ensure the unit is working properly. Coordination (3) unit commissioning can only solve the interlocking device, but can not guarantee removal unit to meet the design requirements, because it involves many factors conditions, bacteria, etc., need to be addressed in a trial run. (4) different process units should be different test methods, purification of industrial waste water, should be implemented in accordance with the detailed design of the supplementary regulations. 3, sub-debug (1) above debugging and unit debugging basically the same, the main water treatment process is classified in accordance with a way of debugging. (2) The general section debugging mainly by oxygen and aerobic two narrow conducted, referring respectively anaerobic, aerobic commissioning instruction manual.
