Description

Technical Field

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

[0002] Sewage refers to water that has been used in life and production activities and has been polluted to varying degrees. This water may contain various harmful substances, such as pathogens, parasites, heavy metals, organic matter, etc. The treatment and purification of sewage is crucial to environmental protection and human health. Sewage mainly comes from households, industries, agriculture and urban infrastructure. Domestic sewage mainly comes from water used in washing, kitchens and toilets, while industrial sewage is wastewater generated during the production process. Agricultural sewage mainly comes from excessive use of pesticides and fertilizers, while urban infrastructure sewage is generated by rainwater, road washing and other urban activities. If sewage is not properly treated and discharged directly into the environment, it will cause water pollution, soil pollution and air pollution. This not only destroys the ecological balance, but may also threaten human drinking water sources and cause various diseases.

[0003] Because sewage contains a large amount of mud and sand, in the sewage treatment pipeline, during the subsequent sewage treatment, the mud and sand may cause blockage to the water treatment device or the water pipeline, which will cause the sewage treatment system to fail to work properly. Therefore, before treating the sewage, the sewage needs to be subjected to sand settling treatment. Sewage sand settling is an important part of the sewage treatment process, which is mainly completed through the sand settling tank. The mud and sand in the sewage are settled, thereby reducing the mud and sand content in the mud and sand to be treated, thereby ensuring that the sewage treatment pipeline will not be blocked.

[0004] The existing means of sedimentation of mud and sand is generally to discharge sewage into a sedimentation tank. By keeping the sewage still, the mud and sand in it naturally settle to the bottom of the sedimentation tank under the action of gravity and accumulate. At this time, the water above a certain water level in the tank is discharged to achieve sedimentation control of sewage mud and sand.

[0005] However, the existing sewage sedimentation tanks generally treat the sewage by allowing the sewage to remain still, thereby allowing the mud and sand in the sewage to settle to the bottom of the tank. However, the efficiency of natural sedimentation is low. In some factories with large sewage treatment volumes, more space or longer time is required to treat the sewage, and the efficiency of sewage and mud treatment is low. Utility Model Content
