Abstract
The utility model relates to a batch membrane biological treatment system, which consists of a grate tank, a regulating tank and an aeration tank. A sewage inlet is arranged on the grate tank, a thick grate and a thin grate are fixed at an inlet of the grate tank from front to back, an outlet of the grate tank is connected with an inlet pipeline of the regulating tank, an outlet of a water pump at the bottom of the regulating tank is connected with an inlet pipeline of the aeration tank, a membrane component is disposed in the aeration tank, an aeration device corresponding to the membrane is disposed at the bottom of the aeration tank and connected with a fan, and a PLC controller is connected with the fan and a water pump circuit respectively. The batch membrane biological treatment system realizes sludge and water separation by aid of membrane filtration (microfiltration or ultrafiltration) replacing activated sludge processes. Compared with the conventional sewage biological treatment technology, the batch membrane biological treatment system has the advantages of reasonable design, compact structure, low investment, low running cost, high solid and liquid separation efficiency, fine outflow quality, high treatment capacity, small space occupation, simple operation and management and the like. Water treated by the batch membrane biological treatment system can be recycled directly or recycled after advanced treatment, thereby realizing sewage recycle.
Description
Technical field
The utility model belongs to separation purifier, particularly relates to a kind of intermittent film biological treatment system.
Background technology
Existing membrane bioreactor (Membrane biological reactors.MBR) is the water technology that the biological degradation with high performance membrane isolation technique and bio-reactor is integrated in one, as MBR and SBR technology, it is to be made of equalizing tank, membrane separation unit, back-purge system, aerating apparatus and washing unit etc., has the membrane module long service life, be convenient to the advantage of operating and managing, but they also have its deficiency, as, occupation area of equipment is big, complex structure, clean and change inconvenience, ammonia nitrogen and phosphorus are removed not thorough, influence the effect of sewage disposal.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and a kind of intermittent film biological treatment system is provided,
Intermittent film biological treatment system of the present utility model is to be made of grating tank, equalizing tank and aeration tank, sewage inlet is arranged on grating tank, ingress in grating tank is fixed with coarse rack and fine fack from front to back, the outlet of grating tank connects with the entrance pipe of equalizing tank, and the outlet of the water pump of equalizing tank bottom connects with the entrance pipe of aeration tank; In the aeration tank, be provided with membrane module, that the bottom is provided with aerating apparatus is corresponding with membrane module, aerating apparatus connects with blower fan; The PLC controller is connected with the water pump circuit with blower fan respectively.
As further improvement of the utility model, the outlet of aeration tank is connected with the vacuum primingpump pipeline, and the PLC controller is connected with the vacuum primingpump circuit.
Treatment step is as follows:
Sewage enters by the pipeline that catchments and enters grating tank, leaches the rubbish of bulk in grating tank earlier by coarse rack (the grizzly bar gap is 50-100 ㎜), then can be by the bulk pollutent of coarse rack by fine fack (the grizzly bar gap is 3-10 ㎜) filtering;
Water enters equalizing tank to the water yield and water quality regulation, regulates sewage pH value to 6-9, reduces impact load, regulates entering the wetland sewage water yield;
Sewage enters in the membrane module bucket processing mechanism by MSBR by lift pump sewage is handled then, and the water treatment amount need be according to sewage quality, the equal practical situation of the water yield and deciding.Finally reach the effluent quality standard, and water outlet.
The utility model intermittent film biological treatment system is realized mud-water separation with the settling tank in membrane filtration (micro-filtration or the ultrafiltration) substitute activated sludge.Compare with the traditional wastewater biologic treating technique, it is low to have reasonable in design, compact construction, less investment, running cost, solid-liquid separation rate height, effluent quality is good, processing power is strong, take up an area of sky asks characteristics such as little, operational management is simple, water quality after this device is handled can direct reuse or further reuse after the advanced treatment, reaches the purpose of sewage recycling.
