Technical Field

The utility model relates to the technical field of sewage treatment, in particular to an oil removal and slag skimming device for a sewage treatment plant.

Background Art

In the treatment of sewage in a sewage treatment plant, a layer of grease and debris often floats on the surface of the sewage. The existing treatment methods often adopt large-scale professional equipment such as deacidification tanks, BAF filters, demulsification devices, and flotation tanks for treatment. However, each of the above facilities occupies a large area, has a high engineering cost, and requires a large amount of labor. If it involves standard improvement and old equipment needs to be reused and renovated, the renovation process requires the entire treatment system to be shut down for a long time, which is quite difficult for the existing sewage treatment facilities. In sewage treatment, it is necessary to remove oil and impurities in the sewage, so an oil removal and skimming device for sewage treatment plants is needed.

In the existing technology, an oil removal and skimming device for a sewage treatment plant is proposed with the announcement number: CN217148876U, comprising a first treatment box and a second treatment box, one end of the first treatment box is connected to the sewage inlet pipe, and the other end is connected to the second treatment box; a filter chamber and an oil removal chamber are sequentially arranged in the first treatment box from the sewage inlet pipe to the second treatment box, and the filter chamber and the oil removal chamber are connected through a partition with filter holes; a heating device and a floating oil adsorption plate are arranged in the oil removal chamber; a heavy oil adsorption plate is arranged in the second treatment box; the utility model can realize the filtration of sewage impurities, floating oil and heavy oil, and improve the impurity removal and oil removal effect of sewage treatment.
