Problems solved by technology

[0006] In order to overcome the problems that the total nitrogen in the effluent cannot reach the standard when the existing biological denitrification technology treats urban sewage, the operating cost is high, and the sludge loss is serious under the condition of low hydraulic retention time, the present invention proposes a combination of "microbial immobilization + anaerobic The integrated system of baffle reactor + membrane bioreactor" is used for the biological denitrification of urban wastewater, and provides an effective process mode and reactor form for the standard treatment of urban sewage. The process is simple, low cost and energy consumption. Low, good water quality

Embodiment Construction

[0042] Below in conjunction with accompanying drawing, the present invention will be further described: figure 2 As shown, a device and method for treating municipal sewage with fixed anammox baffle reactor combined with membrane bioreactor: the device consists of water inlet system, anaerobic baffle reactor, membrane bioreactor, water bath The circulation system and the water outlet system consist of 5 parts.

[0043] The water inlet system comprises a water inlet bottle (1) and a water inlet peristaltic pump (2). The water inlet bottle (1) is sealed with a rubber plug. Two holes need to be drilled on the rubber plug, and two glass tubes should be inserted, one of which is connected to a 50L air bag (to prevent water from being produced in the wide-mouth bottle). Negative pressure, which affects the water inlet speed or causes the bottle wall to break), another plastic pipe connected to the water inlet peristaltic pump (2), and the other end of the plastic pipe is connected...

Abstract

The present invention relates to an immobilized anaerobic ammonium oxidation baffle-membrane bioreactor device and method for treating urban sewage. The device is "microbe immobilization + anaerobic baffle reactor + membrane bioreactor" in The integrated system consists of five parts: water inlet system, anaerobic baffle reactor, membrane bioreactor, water outlet system, and water bath circulation system. Using "anaerobic baffle-membrane bioreactor" to run the anammox process, and introducing microbial immobilization technology, the non-woven fabric carrier used for immobilized microorganisms is placed inside the anaerobic baffle reactor to reduce Sludge loss under the condition of low hydraulic retention time increases the operating load of the reactor and at the same time slows down the membrane fouling. The sludge inside the membrane bioreactor is periodically returned to the anaerobic baffle reactor. The process does not require an external carbon source, has good wastewater treatment effect, low cost and no sludge loss problem.

Description

technical field [0001] The invention belongs to the technical field of waste water biological treatment, and relates to a device and method for treating urban sewage by using an anaerobic baffle reactor combined with a membrane bioreactor to operate anaerobic ammonium oxidation and microbial immobilization technology. Background technique [0002] With the continuous acceleration of urbanization and industrialization, the urban population has increased rapidly, and the generation of urban sewage has continued to increase, which has become the main component of national wastewater. Urban sewage contains a large amount of organic matter, ammonia nitrogen, etc., which are the main factors that cause eutrophication of water bodies and destroy the ecological balance of water bodies. In the past ten years, the traditional denitrification process, namely nitrification and denitrification process, has gradually developed and matured, and has become the most widely used biological de...
