Membrane Bioreactor Wastewater Treatment Plant for Municipal Waste Water

Package wastewater treatment plant for domestic industrial sewage
Brief indtroductionThe package sewage treatment plant is amodular, high-efficiency sewage biological treatment equipment. It is abiological wastewater treatment system that uses biological membrane as the main body of purification. It fully utilizes biological membrane reactors such as anaerobic biological filters and contact oxidation beds. The characteristics of large biological density, strong anti-fouling ability, low power consumption, stable operation and convenient maintenance make the system have awide application prospect and promotion value.At present, there are many sewage treatment technologies used at home and abroad, which are mainly divided into activated sludge method and biofilm methods.The package wastewater treatment plant integrate anaerobic tank, anoxic ank, oxic tank, secondary sedimente tank, Sludge tank and clean water tank into one plant .Detailed equipment introductionProcess flow:Sewage----grid channel---- equalize tank-----anoxic tank-----aerobic tank ------ settling tank ----- cleaning water tank ---- reuse or dischargeGrid channel and equalize tank use civil structure, client build them.The package treatment plant include :dissolved air flotation unit (some sewage need this treatment process), anaerobic tank, anoxic tank, aerobic tank, settling tank and clean water tank.Details for whole plantDissolved air flotation unit :some sewage main contains large amount of suspended matters, such as paper sewage, so need use DAF unit to reduce SS content first.Biological carrier: aerobic and anaerobic bacteria attach to biological carriers, grow and multiply, and form pellicles,they would consume organic matter during growth and reproduction, and purify wastewater.Equipment room: All the electric equipment, control box, pumps, air blowers, water softener and other related equipments are installed in this room. We would install all this equipment ready before leave factory.Aerate system: We use ABS microporous aerator, small aperture, high precision, no clogging. This aerators are placed in oxic tank to add oxygen content in water.Advantage1. Strong resistance to shock loads. The average residence time of the contact oxidation method is more than 6hours;2. It has the ability to remove nitrogen and phosphorus, and can adjust the structure of the equipment to achieve the ability to treat industrial wastewater, domestic sewage, and urban sewage.3. The fillers in the contact oxidation tank are mostly composed of soft fillers, which are light weight, high strength, stable in physical and chemical properties, large specific surface area, strong biofilm adhesion ability, and high contact efficiency between sewage and biofilms; [3]4. In the contact oxidation tank, aeration is used to conduct blast aeration so that the fiber bundles are continuously drifted, the aeration is uniform, and the microorganisms are matured and matured, and have the characteristics of activated sludge method;5. The effluent water quality is stable, sludge production is small and easy to handle;6. The submersible pump can be installed in the equipment to reduce the investment in the project;7, equipment can be located on the ground, but also buried in the ground. When buried in the ground, the upper part can be covered and used for greening. The plant area is small and there are few ground structures;8, easy to complete automatic control, management, operation is simple. [4]9, the device can be connected to the car made of mobile integrated sewage treatment equipment.Model listModelTreatment capacity

Scope of applicationDomestic sewage, residential sewage, residential villages, villages and towns, office buildings, shopping malls, hotels, restaurants, sanatoriums, institutions, schools, military units, hospitals, highways, railways, factories, mines, tourist attractions, etc.Similar processing and reuse of small and medium-sized industrial organic wastewater such as slaughtering, aquatic products processing, and food processing. The wastewater treated by this equipment has reached the Grade IB standard of the national comprehensive wastewater discharge standard.Related productsMechanical bar screen: used in pretreatment process, to remove large solid waste such as peel, confetti, leaves etc. This kind machine is rotary bar screen, rubbish and solids are taken out from water and sent to machien tap, then flow down to scum trap. Self clean no need to clean by worker.Belt oil skimmer: Used in pretreatment process, to remove floating oil in wastewater. Usually used in industrial sewage which have large amount of floating oil.Oil and grease trap:this machine effect is same as belt oil sikmmer, to remove floating oil in sewage.Usually hotel, restaurant sewage have large amount oil, need to remove in advance. If not, this oil and grease will affect the biochemical reaction.Sludge dewatering machine: Sewage treatment process would generate large amount of sludge, his kind of sludge is very dilute and needs to be dehydrated to be able to be pulled to the drying yard for drying, or dried by drying equipment. The sludge dewatering machine include :Stacked screw sludge dewatering machine, frame filter press, belt filter press.Company introduction
