A kind of sewage treatment equipment

Abstract

The invention discloses a sewage treatment equipment. When it is detected that the thickness of the bottom mud at a certain injection point is greater than a preset value or / and the flow velocity of the water is greater than the preset value, at least one medicine containing shell and the moving hull are controlled. Disconnect the connection, so that the agent-containing shell sinks into the bottom mud, so that the agent in the agent-containing shell interacts with the bottom mud, thus increasing the treatment of the bottom mud by the agent and improving the sewage treatment effect; by setting the bottom of the moving hull There are waterproof UV lamps, and the UV lamps are placed in a clever position, which will not occupy additional space, and can also photocatalyze the chemicals put into the water body and sediment to further improve the treatment effect of water and sediment; Moreover, the ultraviolet lamp tube is arranged in a housing in the shape of a concave lens, so that the ultraviolet rays emitted by the ultraviolet lamp tube are diffused through the action of the concave housing, and the irradiation range is larger.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to sewage treatment equipment. Background technique [0002] Water is the source of life and the most important natural resource for human development. Over the years, untreated domestic sewage, agricultural sewage, and industrial wastewater containing pollutants have been discharged into rivers and lakes in some places, and most of the pollutants are finally deposited in the bottom mud of rivers and lakes. The pollutants adsorbed by the deposition will have a lasting impact on the overlying water body. When conditions such as temperature, pH, hydraulic power, and water pollutant concentration change, the pollutants accumulated and adsorbed in the sediment will be released into the overlying water body. The sediment of rivers and lakes is not only the "collection" of pollutants in water bodies, but also the "source" of pollutants in water bodies. Therefore, sewage treatme...

Problems solved by technology

However, because there is a certain distance between the water body and the bottom mud, although the method of injecting chemical and biological agents into the water body can treat both the water body and the bottom mud, in fact only a small part of the chemical and biological agents can reach the bottom mud to treat the bottom mud. Treatment, the treatment effect on the bottom sludge is not great; and because of the different positions of the sewage outlets and the influence of the water flow velocity, the depth of the bottom sludge in different places is also different. Even if the amount of chemical and biological agents is increased near the sewage outlet, Chemical and biological agents will also diffuse and flow away with the flow rate of the water body, and there are very few chemical and biological agents that actually reach the bottom mud, and excessive use of chemical and biological agents into the water body will have an impact on the water body
