An intensive device and method for treating black and odorous water in rural areas

Abstract

The invention relates to the technical field of black and odorous water treatment, and discloses an intensive device and method for treating black and odorous water in rural areas; the device includes a first treatment device and a second treatment device; the first treatment device includes a fixed The provided first circular cavity is a centrifugal drum movably installed on the inner wall of the first circular cavity, and the improved bacterial agent is provided on the upper end of the first circular cavity and communicated with the first circular cavity a throwing device, a plurality of groups of sludge discharge grooves evenly arranged at the lower end of the first circular cavity, and a cylindrical intercepting grille arranged at the inner center of the first circular cavity; the method includes mud-water separation; sediment improvement Treatment of black and odorous water bodies; the technical solution for rural black and odorous water bodies has the characteristics of high treatment quality and quick effect; it is small in size, easy to implement, and has strong practicability.

Description

technical field [0001] The invention relates to the technical field of black and odorous water treatment, in particular to an intensive device and method for treating black and odorous water in rural areas. Background technique [0002] The main reason for the occurrence of black and odor in water bodies is due to the inflow of domestic garbage or sewage containing high concentrations of organic pollutants such as domestic sewage, organic pollutants, ammonia nitrogen and phosphorus in the water body. The concentration of the substance exceeds the standard, and the self-purification ability of the water body is unbalanced, which eventually leads to black odor. The closed black and odorous water bodies seriously pollute the local environment, and the confluence of watershed black and odorous water bodies into the mainstream will also cause serious river pollution. The ecological purification and restoration of black and odorous water bodies is imminent. [0003] Due to the ch...

Problems solved by technology

Closed black and odorous water seriously pollutes the local environment, and catchment black and odorous water merges into the main stream will cause serious river pollution. The ecological purification and restoration of black and odorous water is imminent

[0003] Due to the high dispersion of rural black and odorous water bodies and the wide distribution of point source pollution; according to the existing technology, the idea of ​​​​connecting point source pollution into a line for centralized treatment is obviously not feasible; the treatment of rural black and odorous water bodies is currently available. The black and odorous water body device or system in the technology occupies a large area, which is not suitable for the distribution characteristics of the black and odorous water body in rural areas;
