Problems solved by technology

[0005] In addition, with the development of medicine and agriculture and animal husbandry, the discharge of drugs and pesticides has become a major problem in sewage treatment. Most of the discharged substances are organic micro-pollutants that are difficult to degrade. If they are not completely degraded, they will be discharged into rivers. Adverse effects on human health and the environment in general
Traditional sewage treatment processes are difficult to degrade, so it is necessary to find an effective means to degrade such refractory organic pollutants

Embodiment Construction

[0036] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0037] The invention combines MBBR and MBR two reactors, and is a novel sewage treatment process for double removal of micro-pollutants in water by using microorganisms to degrade pollutants and membrane modules to intercept pollutants. Its mechanism is to use the high biodiversity of microorganisms in the MBBR part of the reactor to biodegrade the organic matter in the sewage and the adsorption of the pollutants by the sponge carrier, and to intercept the pollutants with the membrane components of the MBR part of the reactor to ensure that the effluent Water quality and stability. The pre-stage MBBR process removes most of the organic matter in the water, so as to alleviate the pore blockage of the membrane module and the accumulation of extracellular polymers in the subsequent MBR process, and reduce the operation and maintenance costs.

Abstract

The invention discloses a novel combined MBBR-MBR. The novel combined MBBR-MBR includes an inlet water tank, a reactor, an outlet water tank and an automatic control system which are connected in sequence, the reactor includes a reactor MBBR part and a reactor MBR part, an overflow baffle plate is arranged between the reactor MBR part and the reactor MBR part, and the upper opening of the overflowbaffle plate is has a zigzag shape; and a plurality of sponge carriers are provided in the reactor MBR part, and a hollow fiber membrane module is arranged in the reactor MBR part. The novel combinedMBBR-MBR improves the sewage treatment efficiency and the quality stability of effluent water, overcomes the disadvantage of membrane pollution caused by long-term running of the membrane module in the MBR, and also improves the problem of uneven aeration.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a novel combined MBBR-MBR reactor. Background technique [0002] With the development of modern industry and the needs of people's production and life, the discharge of industrial wastewater and domestic sewage is increasing day by day. The traditional sewage treatment process has disadvantages such as unsatisfactory effect, high residual sludge output, and large land occupation of decontamination process. As a mature sewage treatment method, the activated sludge process has been applied to major sewage treatment plants, but the existing sewage treatment equipment has disadvantages such as low treatment efficiency and unstable effluent quality. [0003] The decontamination process involved in the traditional activated sludge process at this stage includes A 2 O, CASS and SBR, etc., the main purpose is to remove nitrogen, phosphorus, organic matter and SS in ...
