West Baoquan Water Treatment Equipment Co. (www.xianbaoquan.com) is located in Xi'an, Shaanxi Chang'an Building 15, Room 1-2408 Xi'an Changfeng Park Road, Contact: Mr. Wang grease trap construction standards in accordance with national environmental standards, oil wastewater treatment engineering and technical specifications required standard grease traps, sewage discharge when canteens required to achieve the appropriate effluent discharge standards, catering sewage treatment is important, according to the policy requirements of finished stainless steel grease traps, determine the location of the construction project approach geographical location, the amount of wastewater discharges and concentration. Wastewater emissions, the higher the concentration, the higher requirement level processing. 1, to determine the actual amount of water to determine the amount of water in accordance with the following general principles: the amount of water in their day to 1) cafeteria workers, according to 0.16m3 / Block times, according to three meals a day by 10 hours calculated (for each meal operating time is about? 3 to 3.5 hours). The number of migrant workers for 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 standard canteen kitchen grease traps, according to 0.05m3 / person? Times total, calculated by 10 hours a day. Cafeteria serves three meals a day, the number of employees is 100 people, then the treated water is 0.05 × 100 × 3 ÷ 10 = 1.5m3 / h. It should be noted: When selecting the design of water treatment processes 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. Grease trap waste is separated structures and sediment in the oil slick, which is the use of oil in water density differences between the oil-water separation. The method is also used to remove grease trap floating structures wastewater relative density of less than slick one. In the grease trap, the relative density is less than one, the larger diameter oil impurities floating on the water, and water separation; relative density greater than 1, then sank to the bottom of impurities. Therefore, the grease trap is also the sedimentation tank, but mainly from the grease effect. And sedimentation tank similar, it also has advection, vertical and inclined plate inclined flow tube. China currently uses a multi-advection grease traps, some places inclined plane inclined tube or other forms of grease traps.
