Grease trap construction standards in accordance with national environmental standards, oily wastewater treatment project technical specifications, canteens when sewage discharge required to achieve the appropriate effluent discharge standards, catering sewage treatment is very important supply of grease traps, according to policy requirements, treatment methods to determine the geographic location and construction of the project, the amount of wastewater discharges and concentration. Wastewater emissions, the higher the concentration of production of stainless steel grease traps, require higher levels of processing. 1, to determine the actual amount of water to determine the amount of water in accordance with the following general principles: if it is a day of water) cafeteria workers, according to 0.16m3 / seat times, according to three meals a day is calculated by 10 hours (operating time of about every meal? 3 to 3.5 hours). The number of migrant workers to 500 people. Then the treated water is 0.04 × 500 × 3 = 60m3 / day. The amount of water per hour is 60 ÷ 10 = 6m3 / h. 2) internal canteen, according to 0.05m3 / person? Second count, 10 hours a day according to calculations. Cafeteria serves meals, number of employees to 100 people grease traps, its treatment capacity of 0.05 × 100 × 3 ÷ 10 = 1.5m3 / h. It should be noted: When choosing the design of water treatment technology and equipment is based is then multiplied by a factor of 1.2 to 1.5 in the actual amount of water on the basis of the above. Settling down in the grease trap in heavy oil and other impurities accumulate in the sludge hopper to the bottom, through mud tubes into the mud tube. After treatment of the waste water grease overflow is discharged into the drainage pond at the follow-up treatment to remove emulsified oil and other contaminants. There grease trap drain port, open the valve when the drain, if necessary, temporarily close the outlet, in order to improve the oil, drain the oil slick.
