Problems solved by technology
[0004] (2) The color is deep and has a foul smell
[0007] (5) The proportion of nutrient elements required by microorganisms in wastewater is seriously out of balance, the content of organic matter and ammonia nitrogen is high, and the phosphorus element is seriously lacking
Therefore, the treatment method of landfill leachate cannot be directly used to treat the waste water of the transfer station, otherwise the cost will be greatly increased

Abstract
The present invention relates to a combined system of an anaerobic and composite film biological reaction device and a method to treat the mixing wastewater; an anaerobic generating device is arranged inside of a heat-preservation container, whose intake mouth is respectively connected with a diving pump, an alkali-adding container and a phosphor-adding container in the raw water container; the intake mouth and the outtake mouth of the heat-preservation container are respectively connected with the outtake mouth of the diving pump inside of the water-supply container and the intake mouth of the water-supply container; the composite film biological reaction device is provided with a combined filling material, an insolating head and a film component; the outtake of the film component is provided with an outtake pump controlled by an automatic control procedure device; the outtake mouth of the reaction zone in the anaerobic generating device is connected with the intake mouth of the composite film biological reaction device; the refluence mouth of the composite film biological reaction device is connected with the intake mouth of the anaerobic generating device through a refluence pump. The pH value of the mixing wastewater in the transfer station for the living rubbish is adjusted to 7.0-8.5 with the alkali; the phosphor is added into the anaerobic generating device and then is flown into the composite film biological reaction device; the water is discharged by the drainage pump; and some of the sewage mixing liquid will flow into the anaerobic generating device again.
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...
