Description
Technical field
This utility model belongs to technical field of sewage, particularly a kind of MBR method domestic sewage processing system.
Background technology
The sewage produced during human lives, is one of the primary pollution source of water body.Mainly feces and wash water.The sanitary sewage amount that city is discharged everyone every day is 150 ~ 400L, and the sanitary sewage amount that rural area is discharged everyone every day is 90 ~ 150L, and its amount and living standard have substantial connection.Containing large amount of organic in sanitary sewage, such as cellulose, starch, saccharide and fat protein etc.；The most often contain pathogen, virus and parasitic ovum；The chloride of inorganic salts, sulfate, phosphate, bicarbonate and sodium, potassium, calcium, magnesium etc..Total feature is nitrogenous, sulfur-bearing and phosphorous height, under anaerobic bacteria effect, easily gives birth to odorant.
Sanitary sewage such as outer row, by surrounding causes serious pollution, produces severe social influence, so must process.
Summary of the invention
The purpose of this utility model is to provide a kind of MBR method domestic sewage processing system, designs for engineerings such as domestic sewage in rural areas, community life sewage, medical waste water, Treated sewage reusing,
The purpose of this utility model and solve its technical problem underlying and realize by the following technical solutions: a kind of MBR method domestic sewage processing system, it is sequentially connected with lattice coral well, regulating reservoir, anoxic pond, MBR mould pond and sterilization pool, wherein also reflux with anoxic pond and be connected in MBR mould pond, MBR mould pond is also connected with sludge-tank, and sludge-tank is connected with regulating reservoir backflow.
Described sterilization pool is connected with exhaust apparatus.
Described sludge-tank is connected with outward transport equipment.
Native system description of the process:
Sanitary sewage can remove bulky grain particle through the interception function of coarse rack.Then sewage self-flowing enters regulating reservoir, carries out water quality, the regulation of the water yield and carry out preaeration in regulating reservoir, and aeration can reduce sludgd deposition, and can remove a part of COD.Then by sewage pump by sewage lifting to hand basket fine fack, remove small granular suspended matters, process for subsequent biochemical and create favourable condition of water quality.Sewage enters integrated equipment for wastewater treatment after flowing through basket grid.Integrated equipment for wastewater treatment is constituted A/O Biochemistry Reaction System by anoxic pond and MBR membrane cisterna, can effectively remove the TN in sewage.Water outlet gravity flow enters the aerobic biochemical system MBR membrane cisterna of sewage disposal, utilizes the biodegradation of the activated sludge of MBR pond middle and high concentration, can be effectively by the organic pollutant removal in waste water, and clearance reaches more than 90%.Water outlet is extracted out through suction pump and is entered sterilization pool, and carries out disinfection in this pond, the sterilized rear standard discharge of sewage or Reuse on Environment, flush the toilet, dust-proof etc..
Mud in anoxic pond and the excess sludge in MBR membrane cisterna are squeezed in sludge-tank by sludge pump, temporarily store, and are then periodically taken away by environmental sanitation department.
This utility model compared with prior art has clear advantage and beneficial effect.From above technical scheme, this utility model MBR is a kind of new and effective sewage treatment process high performance membrane isolation technics combined with traditional activated sludge process, it is placed in Aeration tank with the immersion type membrane component with unique texture, water after aerobic aeration and biological treatment, by pump by extracting out after membrane filtration.Owing to the existence of film substantially increases the ability of system solid-liquid separation, so that system effluent quality and volumetric loading are all greatly improved.Due to the filtration of film, microorganism is completely trapped in bioreactor, it is achieved that hydraulic detention time is completely separated with Age of Activated Sludge, eliminates sludge bulking problem in traditional activated sludge process.
MBR membrane biological reaction pond is high to contaminant removal efficiency, nitrification ability strong, can carry out nitrification, denitrification, denitrification effect is good, stable effluent quality, excess sludge production are low, facility compact, simple operation and other advantages simultaneously.
