Abstract

The invention discloses an efficient oxygen supply nano-bubble suspended carrier flowing biochemical bed sewage treatment system which comprises a grille, an anaerobic tank, an anoxic tank, an MBBR nano-bubble biological reaction tank and a secondary sedimentation tank. A high-specific-surface-area suspended carrier suitable for attaching propagation of microbial strains is put in the MBBR nano-bubble biological reaction tank, the MBBR nano-bubble biological reaction tank is connected with a nano-bubble machine using an air source as oxygen and is responsible for nano-bubble delivery towards the MBBR nano-bubble biological reaction tank to form high-density nano-bubble water. The sewage treatment system creatively integrates a nano-bubble technology and a suspended carrier flowing biochemical bed technology, a brand new sewage treatment system and a process are formed, the shortcomings of frequent sludge adding, high-energy-consumption blast aeration, sludge reflux, daily aged sludge treatment and the like existing in an existing activated sludge and wastewater treatment system are overcome, and the sewage treatment system also has the advantages of being simple in operation, stable in operation, large in treatment amount and the like.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage treatment system of a flowing biochemical bed of a nano-bubble high-efficiency oxygen supply suspension carrier. Background technique [0002] Dissolved oxygen content is an important indicator reflecting the state of water pollution, and the change process of dissolved oxygen concentration in polluted water reflects the self-purification process of water. Dissolved oxygen plays a very important role in the self-purification process of water body, and the self-purification ability of water body is directly related to the aeration capacity. [0003] At present, most sewage treatment plants use the activated sludge method A invented by Clark and Gage in England more than 100 years ago (1912). 2 O process for anaerobic, anoxic, aerobic biochemical treatment. The activated sludge method has been greatly developed since it was applied to sewage treatment in the early 20th ce...
