The invention provides a sewage treatment system and method based on magnetic coagulation AAS and a magnetization MABR. The sewage treatment system comprises a magnetic-coagulation and anoxic-activated-sludge treating unit, an anoxic sludge magnetic separation unit, a magnetized-nitrified-sludge and membrane separation unit and an aerobic sludge magnetic separation unit. Sewage enters the magnetic-coagulation and anoxic-activated-sludge treating unit, magnetic powder and a chemical coagulant are put for treatment, then the product is separated through the anoxic sludge magnetic separation unit, the separated sewage enters the magnetized-nitrified-sludge and membrane separation unit, magnetic powder is put for treatment, the product is separated through the aerobic sludge magnetic separation unit, and nitrification liquid flows back to the magnetic-coagulation and anoxic-activated-sludge treating unit. By means of the sewage treatment system and method in the technical scheme, nitrogen and phosphorus in the sewage are synchronously and deeply removed, it is guaranteed that carbon and nitrogen are removed through organisms, membrane pollution is effectively relieved, and the sewage treatment system and method have the better de-nitrification effect, phosphorous removing effect and nitration effect and the shorter sludge-water mixed liquid separating time.
Description
technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a sewage treatment system and treatment method based on magnetic coagulation AAS and magnetized MABR. Background technique [0002] At present, the "centralized" sewage treatment system is in the mainstream position in the world, but under the influence of the trend of sustainable development, it is reflecting on the shortcomings of centralized sewage treatment, which is a terminal treatment in terms of recycling resources and energy in sewage, and will then develop and applied interest towards decentralized processing, especially source control. The International Institute for Water Quality (IAWQ) even proposed at the "Small Sewage Treatment Facilities" symposium: the population equivalent is below 2000 or the flow is 200m 3 Sewage stations below / d are small sewage stations. Numerous studies have pointed out that the construction of miniaturized sewage tre...
