Aerobiotic three-phase separator with guide tube and application method of aerobiotic three-phase separator in sewage treatment

Abstract

The invention relates to an aerobiotic three-phase separator with a guide tube. The aerobiotic three-phase separator comprises two end plates and guide plates, wherein the two end plates are formed by bottom inverted trapezoidal plates and top rectangular plates in an integrated manner; the guide plates are vertically connected with two side edges of the two end plates; rectangular cavities are formed in the tops of the guide plates; bottom ends of the two guide plates are respectively bent inwards and are vertically connected with two side edges of the bottom inverted trapezoidal plates of the end plates to form inclined plates of a bottom conical cavity with a sludge backflow seam. The aerobiotic three-phase separator is characterized by further comprising an overflow weir, a discharge tube and a conical sludge hopper, wherein the overflow weir is formed between the end plates of the horizontal axis of the top rectangular cavity; the water discharge tube is arranged between the bottom of the overflow weir and the inclined plates; the conical sludge hopper is formed by the inclined plates and the two end plates in a surrounding manner; a plurality of first through holes are formed in side surfaces of the guide plates; the first through holes are connected with a guide tube to the inclined plates. By adopting the aerobiotic three-phase separator with the guide tube, powerless automatic backflow of sludge is achieved, microorganisms of a relatively long generation cycle can be effectively retained, and the age of sludge can be prolonged, so that the treatment efficiency can be improved, and the floor space of a facility can be reduced.

Description

technical field [0001] The invention relates to a separation and precipitation device, in particular to a gas, liquid and solid three-phase separator used in an aerobic biological treatment process. Background technique [0002] The aerobic activated sludge method is a relatively mature biological treatment technology, which is widely used in the current urban sewage treatment. In the treatment of some high-concentration industrial wastewater, the anaerobic sewage must also pass through the aerobic activated sludge. method for processing. The factors that play a key role in the treatment effect in the aerobic activated sludge sewage treatment system are mainly sludge concentration (amount of microorganisms), dissolved oxygen efficiency (microbial activity) and sedimentation efficiency (mud-water separation effect), that is, good The sewage treatment system of the oxygen active substance method will involve the contact and separation of gas, liquid and solid three-phase, and...

Problems solved by technology

During this process, the activated sludge will continue to circulate between the aerobic and sedimentation tanks. On the one hand, it consumes a lot of energy. On the other hand, due to the continuous change of the microbial growth environment, its biological activity is reduced, which is not conducive to the biodegradation reaction. carry out
