Abstract
The utility model discloses a membrane bioreactor which belongs to the technical field of water treatment equipment for environmental protection, particularly equipment using a hollow fiber membrane to treat sewerage. The membrane bioreactor comprises a shell body, a water inlet, a water outlet, an aerating machine and a membrane assembly, wherein the shell body is divided into two parts through a baffle, and a water pipe connected with the water inlet extends to the bottom of the shell body to connect with a water-distributing pipe provided with holes. The aerating machine is arranged at the bottom of the shell body, and suspension filling material is filled in the shell body. An upper annular water pipe and a lower annular water pipe of the membrane assembly are fixedly arranged on one side of the baffle, and the annular water pipes and a water outlet pipe are connected with the water outlet. The membrane bioreactor has the advantages of compact structure, small size and convenient installation. The water quality of the treated sewerage is in accordance with the standards of domestic water, and the utility model is suitable for sewage treatment and intermediate water reclamation of civil buildings, such as hotels, house buildings, etc.
Description
Affiliated technical field
The utility model belongs to environment protection water treating equipment technical field, the equipment that particularly uses hollow-fibre membrane to dispose of sewage.
Background technology
Present many cities are water recycling device in experimental study technology of middle water recycle and exploitation all.But generally all adopt biochemical and materialization process combined.Promptly on the basis of biological treatment, again by coagulation, pressure filtration, chemical disinfection processing step, with sanitary sewage disposal to middle water reuse standard.Chinese patent CN2466143 disclose a kind of integrated in water recycling device the active sludge aeration tank be assembled into one with the membrane sepn aeration tank of dress hollow fiber membrane module and hydraulic pipe in it reduced the volume of reclamation set, but usefulness active sludge efficient is high not enough.
Summary of the invention
The purpose of this utility model provides a kind of further raising biological degradation and film high efficient separation technology bonded membrane bioreactor.
The technical solution of the utility model is, membrane bioreactor comprises housing, water-in, water outlet, aerator, membrane module, dividing plate is divided into biological respinse chamber and membrane module chamber two portions with housing, leading to housing bottom with the water-in water pipe connecting in the biological respinse chamber links to each other with water distributor with holes, aerator is installed in housing bottom, the indoor suspension filler that is equipped with of biological respinse, at the indoor annular conduit up and down that membrane module is installed of fixing of dividing plate opposite side membrane module, annular conduit is connected with rising pipe and leads to water outlet.
Water distributor with holes can be the parallel distribution of 2-6 root, also can annular spread.
Aerator can be the 1-5 platform.
Membrane module can be the center processing monolithic for tubular fibre external-compression type or microfiltration membrane.
The suspension filler can be the hollow porous spherical PE material of proportion between 0.6-0.95.
The beneficial effects of the utility model are, the utility model has adopted a kind of novel high-efficiency sewage that begins this high efficient separation technology be combined into biological degradation and film of the membrane bioreactor (MBR) that develops in recent years to handle and reuse technology.The utility model replaces active sludge after bacterial classification is rendered in the membrane bioreactor with the suspension filler in the aeration tank, just very fast suction can reach 1,000,000,000/cm attached to filling surface after the oxygenation breeding
2, the use of aerator under the combination water again can increase substantially biological treatment effect, significantly reduces the generation of mud.The one chip membrane module has that big, the permeable amount of surface-area is big, oxidation-resistance is strong, stable water outlet, should not block, characteristics such as easy for installation.After pretreated sewage enters membrane bioreactor, contact during application, to the metabolic activity of microorganism such as organic pollutant adsorption, decomposition in the sewage sewage is purified by microbial film with high-performance bio film on the filler in the biological reaction tank.The mixed solution that purifies through bio-reactor enters the membrane module chamber from the dividing plate top, and under the effect of the water pump that is connected with water outlet, mixed solution is realized solid-liquid separation by membrane module, and clear water sees through film and enters rising pipe; Concentrated solution flows into sludge thickener and concentrates.The membrane bioreactor that provides with the utility model is the middle water reuse apparatus that main body is made, and is COD through application test when intaking
Cr450-500mg/L, BOD
5200--250mg/L, effluent quality can reach COD during SS150--220mg/L
Cr＜20mg/L, BOD
5＜5mg/L, SS=0mg/L.In sum this reactor have little easy for installation, the sewage of compact construction, volume after treatment water quality meet the reclaimed water standard.Be fit to covil construction sewage disposal and middle water reuses such as hotel, residential building.
