Description
Technical field
The invention belongs to energy-conserving and environment-protective technical field, be specially a kind of municipal sewage system.
Background technology
Municipal effluent (municipalsewage, municipalwastewater) enters the general designation of the sewage of town sewage system.In combined drainage system, the rainwater also comprising factory effluent He retain.Municipal effluent mainly comprises sanitary sewage and industrial sewage, is collected and be transported to sewage work to process by urban drainage pipe network.Urban sewage treatment process generally considers the natural purifying ability of water body according to the utilization of municipal effluent or emission direction, determines the degree for the treatment of of sewage and corresponding treatment process.Sewage after process, no matter for industry, agricultural or recharge recharge of groundwater, all must meet the relevant water quality standard that country issues.Modern sewage treatment technology, divides by degree for the treatment of, can be divided into one-level, secondary and tertiary treatment process.Sewage coagulation Applied Physics method, as sieving, precipitation etc. remove undissolved suspended solids and floating substance in sewage.Sewage second-level process is applying biological treatment process mainly, is namely carried out the process of Substance Transformation by the metabolism of microorganism, and the oxidation operation of the various complexity in sewage is degraded to simple material.Biological treatment has certain requirement to the dissolved oxygen amount in sewage quality, water temperature, water, pH value etc.Tertiary sewage treatment is on the basis of I and II process, and physics such as application coagulation, filtration, ion-exchange, reverse osmosis etc., chemical process to remove in sewage the nutritional substances such as insoluble organism, phosphorus, nitrogen.Pollutent composition in sewage is very complicated, usually needs above several method to combine, just can reach processing requirements.Sewage coagulation is pre-treatment, and second-stage treatment is main body, and the sewage after process generally can reach emission standard.Tertiary treatment is advanced treatment, and effluent quality is better, even can reach drinking water quality standard, but processing costs is high, except except the countries and regions of some extreme dehydration, applies less.The many cities of current China are under preparation and extend sewage second-level treatment plant, to solve day by day serious water pollution problems.
The Novel state Waste Water Treatment that film-bioreactor (MembraneBio-Reactor, MBR) is membrane separation technique and biologic treating technique combination.Replace traditional biological treatment technology end second pond with membrane module, in bio-reactor, keep high reactivity sludge concentration, improve biological treatment organic loading, thus reduce sewage treatment facility floor space, and by keeping low sludge loading to reduce surplus sludge volume.Mainly utilize the active sludge in membrane separation plant trap water and larger molecular organics.In membrane bioreactor system, active sludge (MLSS) concentration can be promoted to 8000 ~ 10,000mg/L, even higher; Sludge age (SRT) can extend to more than 30 days.Membrane bioreactor is because of its effective crown_interception, and can retain generation cycle longer microorganism, can realize deep purification of waste water, Simultaneous Nitrification bacterium can fully breed in system, and its nitrification effect is obvious, provides possibility to deep phosphorous removal denitrogenation.
