1. The design department can be consulted and the corresponding design will be made according to the size of the hotel. Sewer is an important problem, so it is suggested to do secondary sewer, that is, install an isolation device below the pool and above the sewer to facilitate dumping the garbage flowing into the sewer into the garbage can every day, so as to prevent the sewer from being blocked.
2. Most of the oil tanks are made of reinforced concrete, and some are also made of masonry. On the rectangular plane, they are divided into three compartments along the direction of water flow, and the width of each compartment is generally less than 6 meters, so as to distribute water evenly. The effective water depth is less than 2 meters, and the length of the oil separation tank is generally more than 4 times the width of each cell. Generally, the grease trap should be covered with a steam pipe under the cover plate, so as to keep warm, prevent the grease trap from catching fire and oil products from volatilizing, and prevent the dust and sand from entering.
internal structure diagram of the oil tank The internal structure of the carburetor highlights the oil-water separation function. By applying the principle of opposite flow separation and the dialectical relationship between turbulent flow and laminar flow, the flow speed of sewage is reduced during the process of flowing through the oil-water separator. By increasing the cross section, the hydraulic retention time of wastewater is increased (about 5-11min), and the whole cross section can flow at a constant speed.

Danger of clogging of oil tank
Catering grease is the most troublesome thing, especially for large hotels, if they don't build an oil tank, the pipeline will be blocked by oil pollution in future use, which will bring inconvenience to their work, and the cost of dredging large pipelines will be thousands of dollars far exceeding the cost of building an oil tank. The blockage of the main pipeline also affects the normal life of other users.
cleaning methods of chemical oil pool are integrated
There are mainly physical treatment, biochemical treatment and chemical treatment. Biochemical treatment is often used, and the mainstream treatment mainly depends on the treated water quality and the receiving water body. Generally, the mainstream treatment methods of urban domestic sewage are biochemical treatment, such as activated sludge method and mbr.
