Description
Technical field
The utility model relates to field of Environment Protection, is mainly used for sanitary sewage disposal project, particularly a kind of a kind of Sewage treatment systems and multistage polyphasic flow aeration mixing device being applicable in middle-size and small-size sanitary sewage disposal factory.
Background technology
The biological treatment mode that sanitary sewage mainly adopts both at home and abroad at present, biological treatment mainly contains the types such as activated sludge process, biomembrance process, and these two kinds main biological treatment modes there is no in a water treatment building to be used.Sewage after biological treatment, carries out separated by water with body refuse if generally all will build second pond.
Activated sludge process generally adopts anaerobism, anoxic, the microbiological treatment process such as aerobic to process, utilize different from various microorganism growth in oxygen situation, absorb and oxidation sanitary sewage in COD(chemical oxygen demand (COD)), the pollution such as nitrogen, phosphorus, for improving water treatment effect, each reaction process all adopts the mode of part sludge reflux, culturing micro-organisms.At present, more advanced sequencing batch active sludge (SBR) is a kind of active sludge sewage disposal technology moving by intermittent aeration mode.Adopt the operating method of cutting apart between the operating method instead of null of time division, astable biochemical reaction substitutes stable state biochemical reaction, and standing desirable precipitation substitutes traditional dynamic precipitation.
Biomembrance process is the method for utilizing the microorganism (be microbial film) of apposition growth in some solids surface to carry out organic sewage processing.
Generally, the sewage that enters Sewage Plant enters biological tank and all will use water pump lifting before, enters biological tank or adopts drop, or adopt submerge discharging flow.But no matter be drop or submerge discharging flow, have certain mechanical energy (kinetic energy) when sewage enters biological tank, these energy all do not have to utilize substantially; Even if drop enters biological tank, drop process and air contact surface are all little, and aeration effect is very little.
Conventionally with in situation, the aeration of biological tank mainly adopts gas blower to the mode of aeration in pond.Sometimes also adopt sludge pump, carry out sludge reflux.This mode is processed sanitary sewage, and effect is relatively good, and the water quality of dispatching from the factory is also guaranteed, and both aerating apparatus in water treating pond also has sewage and mud mixing reflux.But because gas blower is to aeration in pond, the form by air with bubble contacts with sewage and microorganism thereof once, and the utilization ratio of oxygen is not high; In addition, the recirculate mixing device of sewage and mud also needs power; Therefore conventional sewage treatment process energy consumption is large, and running cost and construction cost are all higher.
Also have some sewage works to adopt jet-flow aerations, extended sewage and air duration of contact, the utilization ratio of oxygen improves, but effect ideal not enough.
