Problems solved by technology

[0003] However, in the actual process of sewage treatment, due to insufficient dissolved oxygen, excessive aeration or low organic load, the nutrient source of water quality microbial strains is deficient in iron, which will cause the strains to become microthrix, and Excessive proliferation of filamentous bacteria will cause the problem of sludge bulking; once the activated sludge expands, its settling effect will be greatly reduced, making the separation of mud and water more difficult and even impossible to separate. The problem of a large amount of loss will also deteriorate the water quality of the overall sewage treatment plant
[0004] In view of the above problems, the method of increasing weighting agent or flocculant is proposed in the prior art to alleviate the problem of sludge bulking, but this method needs to consume a large amount of weighting agent or flocculant. First, the cost is high, and the other One is that the long-term use of chemical agents to control will lead to the resistance of filamentous bacteria, which still cannot effectively solve the problem of sludge bulking

Abstract

The invention belongs to the technical field of sewage treatment, and discloses an intelligent town sewage treatment device based on biological regulation, which comprises a pretreatment tank, an aeration tank, an anaerobic-film biological generator, an anaerobic fermenter, an aerobic tank and a disinfection tank, the aeration tank is connected with the anaerobic-film biological generator, and anaeration-stirring device of which the surface is chelated with iron ions is arranged in the aeration tank; the aerobic tank is connected with the disinfection tank, and the bottom of the aerobic tank,the bottom of the anaerobic fermenter and the bottom of the aeration tank are connected with one another to form an anaerobic-aerobic circulation system of the activated sludge; according to the invention, effective separation of sludge retention and hydraulic retention is realized based on the film biological generator, and subsequent anaerobic fermenters and aerobic tanks are combined for further treatment respectively; a circulating system capable of eliminating filamentous bacteria is formed among the anaerobic fermenter, the aerobic tank and the aeration tank, so that the problem of sludge bulking is effectively solved under the condition that the structure of the device is not changed.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an intelligent urban sewage treatment device based on biological control. Background technique [0002] Activated sludge method is the most widely used biological control sewage treatment method in urban sewage treatment plants, which has the advantages of economy and good treatment effect. Activated sludge is mainly composed of microorganisms that can absorb and degrade organic matter in sewage and pollutants such as nitrogen and phosphorus; during the treatment process, activated sludge is mixed with sewage and is in a suspended state, and the treated mud-water mixture enters the secondary sedimentation process. Separation of mud and water is realized in the pool to prevent the loss of activated sludge with the effluent, and achieve the purpose of recycling activated sludge while discharging clean water. [0003] However, in the actual process of sewage tr...
