Urban sewage purification treatment device

Abstract

The invention belongs to the technical field of urban sewage treatment, and particularly relates to an urban sewage purification treatment device. The device comprises a mechanism box, symmetrical filter frames are fixedly connected to the upper surface of the mechanism box, cover plates are fixedly mounted at the top ends of the two filter frames, and water injection connectors are fixedly embedded in the upper surfaces of the two cover plates. The top ends of the two water injection connectors fixedly communicate with conveying pipes, the ends, close to each other, of the two conveying pipes jointly and fixedly communicate with an injection pipe, symmetrical sliding holes are formed in the inner side walls of the two filtering frames, sliding plates are slidably connected to the inner walls of the two sets of sliding holes, and grids are arranged in the two filtering frames. According to the sewage purification treatment device, by arranging the sewage purification treatment assembly, sewage can be effectively precipitated and filtered, intercepted pollutants in the sewage can be conveniently cleaned, the sewage purification effect of the sewage purification treatment device is improved, and water resources can be better utilized conveniently.

Description

technical field [0001] The invention relates to the technical field of urban sewage treatment, in particular to an urban sewage purification treatment device. Background technique [0002] Urban sewage treatment refers to measures taken to change the nature of sewage so that it does not cause harm to environmental waters. Urban sewage treatment is generally divided into three levels. The first level of treatment is to use physical treatment to remove insoluble pollutants and parasites in sewage. Insect eggs; secondary treatment uses biological treatment to oxidize and degrade various complex organic matter in sewage into simple substances; tertiary treatment uses chemical precipitation, biochemical and physical chemical methods to remove phosphorus, Nitrogen, refractory organic matter and inorganic salts, etc. Generally, the primary treatment of urban sewage treatment is the pretreatment, the secondary treatment is the main body, and the tertiary treatment is rarely used.

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides an urban sewage purification treatment device, which solves the problem that the existing urban sewage purification treatment equipment is inconvenient to clean up the intercepted pollutants in the sewage, which will affect the effect of the grid on the pollutants. The interception effect, and the current sewage purification treatment device cannot effectively settle and filter the sewage, thereby reducing the sewage purification effect of the sewage purification treatment device, which is not convenient for better utilization of water resources
