Description

Sewage treatment equipment with multistage filtration Technical Field The utility model relates to the technical field of sewage treatment, in particular to a multi-stage filtration sewage treatment device. Background The sewage treatment equipment is special equipment for treating sewage, and can remove pollutants in the sewage through physical, chemical or biological methods, so that the water quality reaches the discharge standard or the recycling water quality requirement, untreated sewage possibly contains various harmful substances including organic matters, nitrogen compounds, phosphorus compounds, heavy metals, bacteria, viruses and the like, if the pollutants are directly discharged into natural water, the pollutants can cause serious threat to the ecological system and human health, the sewage treatment equipment can also promote the reutilization of water resources, and the properly treated sewage can be used for a plurality of fields such as irrigation farmlands, industrial water, urban greening and the like, so that the dependence on fresh water resources is reduced. In the existing sewage treatment process, waste gas containing harmful substances, such as malodorous gas, is often generated, if the waste gas is directly discharged into the atmosphere, the waste gas can form a potential threat to the surrounding environment and the health of residents, so that the environmental pollution problem is aggravated, for example, a waste water treatment tank for preventing the diffusion of the odor is disclosed in the publication No. CN222524211U, although the sealing cover plate in the patent can effectively prevent the diffusion of the odor, an active gas purifying function is not provided only in a physical sealing manner, which means that if the harmful and odorous gas is generated in the treatment tank, the harmful and odorous gas is trapped in the treatment tank and cannot be effectively removed, and the accumulated harmful and odorous gas for a long time can cause the air quality in the treatment tank to be deteriorated, so that the potential threat to the health of operators, especially in a closed or ventilated environment is more remarkable.
