Description

Technical Field

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

[0002] Urban sewage includes but is not limited to domestic sewage (such as household washing, bathing, and kitchen drainage), commercial sewage, some initial rainwater, and a small amount of industrial wastewater. This type of sewage usually contains organic matter, nitrogen, phosphorus, suspended solids, pathogenic microorganisms, and other substances that may pollute the environment. If sewage is not treated, it will have many adverse effects on people's lives.

[0003] Urban sewage is wastewater generated during the daily life of urban residents, commercial activities, industrial production and operation of public facilities. Sewage contains fixed garbage. If it is not filtered and intercepted, the sewage treatment device will be blocked, thereby reducing the sewage treatment effect. Maintenance is also time-consuming and labor-intensive. In addition, urban sewage also contains a large amount of silt and other particulate matter. The precipitated silt is not easy to remove from the sedimentation tank, so the sedimentation tank is too thick to clean. Utility Model Content
