Abstract

The invention relates to an anaerobic composite membrane bioreactor combination system and a method for treating mixed wastewater. The anaerobic generator is placed in an incubator, and its water inlet is respectively connected to a submersible pump, an alkali adding tank, and a phosphorus adding tank in a raw water tank. tank; the inlet and outlet of the incubator are respectively connected to the outlet of the submersible pump in the tap water tank and the water inlet of the tap water tank; the composite membrane bioreactor has built-in composite packing, aeration head, membrane module, and membrane module outlet connection The water outlet pump controlled by the automatic control programmer; the water outlet of the reaction zone in the anaerobic generator is connected to the water inlet of the composite membrane bioreactor, and the return port of the composite membrane bioreactor is connected to the water inlet of the anaerobic generator through the reflux pump. The mixed wastewater from the domestic waste transfer station adjusts the pH to 7.0-8.5 with alkali, and supplements phosphorus, then enters the anaerobic generator, and then overflows into the composite membrane bioreactor. The effluent is sucked by the effluent pump, and part of the sludge at the outlet is The mixed solution is returned to the anaerobic generator.

Description

technical field [0001] The invention relates to a system and method for harmless treatment of high-concentration organic waste water, in particular to a system and method for treating mixed waste water in a garbage transfer station with a membrane bioreactor. Background technique [0002] As the hub of garbage collection and final treatment, the domestic garbage transfer station is becoming more and more popular in large and medium-sized cities, and the environmental pollution it brings has also attracted more and more attention. The waste water in the waste transfer station is a mixture of various waste water, including not only the waste compressed water in the station, but also domestic sewage, productive waste water, fecal sewage and kitchen waste water discharged from various other channels. Among them, garbage compressed water COD, BOD 5 and ammonia nitrogen content are extremely high, and the biodegradability is poor. After other wastewater is mixed with garbage com...
