Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an oil-water separator for domestic sewage treatment. Background Art

[0002] Due to environmental protection requirements, sewage generated in life must be treated before being discharged into rivers, lakes and seas. Oil-water separators are needed to treat sewage:

[0003] Most of the existing oil-water separation methods use physical separation, where the sewage is kept still inside the storage tank, and the oil will float to the surface of the water. The oil is then collected through secondary filtration on the honeycomb plate.

[0004] There are some problems. Since the sewage contains oil, after physical separation, the oil and water float upward. Long-term stagnation will cause the oil to clump and be unable to pass through the honeycomb holes. The dirt in the sewage will remain inside the device, affecting subsequent operations and causing accumulation and blockage. For this reason, we propose an oil-water separator for domestic sewage treatment. Utility Model Content
