The activated sludge process is a biological waste water treating technology, and is mainly a biological waste water treating process with activated sludge as main component. This technique mixes and agitates the wastewater with activated sludge (microorganisms) and aerates to decompose organic contaminants in the wastewater, and biosolids are then separated from the treated wastewater and optionally partially returned to an aeration tank. The activated sludge process is a process in which air is continuously introduced into the wastewater and sludge-like flocs are formed by the proliferation of aerobic microorganisms after a certain period of time. The microorganisms mainly including zoogloea inhabit on the microbial pool, and have strong capability of adsorbing and oxidizing organic matters.
In the sewage treatment by the activated sludge method, an aerobic aeration tank, which is a structure for performing sewage treatment by the activated sludge method, is a very important process segment. The pool can provide a certain time for the sewage to stay, so as to meet the oxygen content required by aerobic microorganisms and the mixing condition of full contact between the sewage and the activated sludge. The aeration tank mainly comprises a tank body, an aeration system and a water inlet and a water outlet. The tank body is generally made of reinforced concrete, and the planar shape of the tank body is rectangular, square, circular and the like.
However, in the existing situation, the aeration system in the aeration tank does not completely cover the bottom of the tank, but is arranged at intervals at the bottom of the tank, when aeration is carried out, gas floats upwards, sewage and activated sludge above the aeration pipes can be fully contacted with the gas, but the sewage and the activated sludge between the adjacent gas injection pipes cannot be rapidly contacted with the gas, so that an aeration blind area can be formed, the activity of the activated sludge in the sewage is in an unbalanced state, the treatment effect of the sewage is influenced, and the technical scheme is limited.
