Generally speaking, the drainage system of hot pot restaurants should be made into a drainage ditch, with a cover on it to facilitate drainage, and the hole spacing of the cover should not be too large to prevent rats. Because the oil pollution at the bottom of hot pot restaurant is relatively large, it is necessary to take oil-water separation measures, install the oil-water separator at the drainage end and maintain it regularly. If the sewer pipe is not maintained and cleaned for a long time, the oil pollution will easily hang on the wall after a long time, and it will be difficult to clean it.

I hope my answer is helpful to you.
