Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and in particular relates to a sedimentation device for sewage treatment. Background Art

[0002] Wastewater treatment: the process of purifying wastewater to meet the water quality requirements for discharge into a water body or reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering. It is also increasingly entering the daily lives of ordinary people. According to the nature of water pollution, there are two types of water pollution: one is natural pollution; the other is man-made pollution. Currently, man-made pollution is the most harmful to water bodies. Water pollution can be mainly divided into three categories: chemical pollution, physical pollution, and biological pollution according to the different pollutants. The main pollutants are: ⑴ Untreated industrial wastewater; ⑵ Untreated domestic sewage; ⑶ Agricultural sewage that uses a large amount of fertilizers, pesticides, and herbicides; ⑷ ​​Industrial waste and domestic garbage piled up by the river; ⑸ Soil erosion; ⑹ Mine sewage. When treating sewage, a sedimentation tank or sedimentation box is used to precipitate the sewage. However, at present, sewage is precipitated by generally using flocculants, which lack the corresponding stirring and mixing function. As a result, after the flocculant is added to the sewage, the flocculant cannot be mixed with the sewage in time, which greatly increases the sedimentation time of the sewage and reduces the sewage treatment effect. Therefore, a sedimentation device for sewage treatment is needed. Utility Model Content
