The sewage treatment device is characterized in that the sewage treatment device comprises a water collecting tank, a raw water pump, a BAF and an MBR, wherein the BAF is filled with biological fillers; an immersion type membrane assembly is mounted in the MBR; the water producing end of the immersion type membrane assembly is connected with a self priming pump and a water producing pool through a water producing pipeline; and the BAF and the MBR also include aerator pipelines which are connected with a blower. Through the combination of sewage treatment technology of BAF and MBR, the sewage treatment device has the advantages that BOD, COD and other pollutants in sewage can be effectively removed, the water outlet quality is steady, the automation degree is high, and the water outlet quality meets the reuse standard.
Description
Technical field
The utility model relates to a kind of waste disposal plant, particularly relates to a kind of based on the BAF-MBR waste disposal plant.
Background technology
Along with The development in society and economy and Increase of population, water resources has become the restraining factors of national economy Sustainable development.The water resources crisis that China faces is severe more, and China's water resources per capita only is 1/4th of world's per capita share, rapid development of economy, and industrial and agricultural production water and total amount of pollutants discharged constantly increase, and wastewater treatment rate is not high, has increased the weight of the natural water pollution.Therefore, improve the sewage disposal level, the waste water treating and reutilizing device that exploitation is suitable not only can the conservation of nature environment, has also solved present water scarcity problem.
BAF (BAF) is a kind of sewage treatment technique of the later development 1980s, essence is a kind of biomembrance process, i.e. filled biomass filler in the aeration tank utilizes the processing unit of the microbial film degraded water pollutant that filling surface adheres to.Since selected filler self, the easy attached biological film of filling surface.The microorganism of numerous kinds and the quantity of growing in the microbial film has aerobic bacteria, and hold concurrently oxygen bacterium, anerobe so BAF all has a good effect of removing to the various organism in the water, also have very high removal efficient to ammonia nitrogen simultaneously.Though yet BAF efficient height, the water source that is only applicable to sewage of low concentration advanced treatment and the little pollution of former water is handled, and can't remove refractory organic.
MBR claims membrane bioreactor (Membrane Bio-Reactor) again, is a kind of novel water technology that is combined with biological processing unit by film separation unit.Membrane bioreactor is a kind of novel process that biologic treating technique combines with membrane separation technique, replaced the second pond in the traditional technology, it can carry out solid-liquid separation efficiently, directly used stable in water, can in biological tank, keep the microbial biomass of high density again, the technology excess sludge is few, the utmost point is removed ammonia nitrogen effectively, goes out water suspension and turbidity and approaches zero, and bacterium and virus are removed significantly in the water outlet, energy consumption is low, and floor space is little.
Summary of the invention
The purpose of this utility model is, based on BAF and membrane bioreactor modern technique, provides a kind of based on the BAF-MBR waste disposal plant, the purpose of reach fast, efficiently disposing of sewage.
For achieving the above object, the technical scheme that the utility model proposes is, a kind of based on the BAF-MBR waste disposal plant, it is characterized in that comprising the water collecting basin that connects successively by pipeline, raw water pump, BAF (BAF), membrane biological reaction pond (MBR), be filled with biologic packing material in the described BAF, the submerged membrane assembly is installed in the described membrane biological reaction pond, the submerged membrane assembly produces water end (W.E.) and links to each other with the product pond with vacuum primingpump by the water producing pipe road, also contain aerated conduit in described BAF and the membrane biological reaction pond, aerated conduit links to each other with gas blower.
Further, bottom, described membrane biological reaction pond links to each other with BAF by a reflux line, and reflux pump is housed on the reflux line, and dense water suction is back in the BAF.
Preferably, the aerated conduit in the described BAF is two groups.
Preferably, contain the boring aeration device on the described aerated conduit.
Further, the biologic packing material in the described BAF is zeolite or modified zeolite filtrate.
Further, described submerged membrane assembly is immersion ceramic film component or immersion hollow fiber film assembly.
Further, also be connected with a backwash pipeline on described product pond and the vacuum primingpump.
