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 invention relates to a device and method for treating urban waste water through an immobilized anammox baffled-membrane bioreactor. The device is an integrated system integrating microbial immobilization, an anaerobic baffled reactor and a membrane bioreactor, and is composed of five parts of a water inlet system, the anaerobic baffled reactor, the membrane bioreactor, a water outlet system and a water bath circulation system. The anaerobic baffled-membrane bioreactor is adopted for running an anammox process, a microbial immobilization technology is introduced, a non-woven fabric carrierused by immobilized microorganisms is placed in the anaerobic baffled reactor, sludge loss under the low hydraulic retention time condition is reduced, the reactor running load is increased, and meanwhile membrane fouling is slowed down. Sludge in the membrane bioreactor flows back into the anaerobic baffled reactor regularly. According to the technology, no carbon source needs to be added, the waste water treatment effect is good, the cost is low, and the sludge loss problem does not exist.

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...
