Abstract

The invention discloses a multi-channel cyclic treatment method for sewage with different contents. The method comprises the following steps: step 100, injecting sewage into a sedimentation tank for preliminary sedimentation, and respectively introducing the sewage having been subjected to preliminary sedimentation into a three-dimensional aeration structure through multiple channels according tolayering conditions for differentiated internal-circulation aeration purification; step 200, respectively carrying out internal-circulation aeration treatment on the sewage of different layers in different laminated layers until the sewage in each laminated layer does not change any more, and then carrying out external-circulation activation aeration treatment on the sewage in different laminatedlayers; and step 300, after aeration operation is completed, performing water-sludge separation on the sewage; According to the invention, differential compensatory aeration is carried out based on sewage of different layers, and then multi-channel external-circulation aeration is carried out, so the content difference of the sewage of different layers can be balanced, and optimal purification effect is achieved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a multi-channel circulation treatment method for sewage with differential content. Background technique [0002] With the continuous development of the processing and manufacturing industry and the continuous advancement of science and technology, the amount of wastewater produced is increasing. Due to the increasing emphasis on environmental protection and the higher and higher requirements for the quality of life, the treatment requirements for wastewater It is also getting higher and higher. [0003] As a common treatment method in sewage treatment, biological treatment mainly uses the biochemical action of microorganisms to oxidize and decompose organic pollutants and some inorganic poisons dissolved in sewage, and convert them into stable and harmless inorganic substances. . However, since it needs to carry out aeration treatment in the aeration tank containing mi...
