Baoquan West Water Treatment Equipment Co., Ltd. (www.xianbaoquan.com) is located in Xi'an, Shaanxi Chang'an Building 15, Room 1-2408, Xi'an Changfeng Park Road, Contact: Mr. Wang is not the construction of the grease trap is an important cause of clogged sewer Every winter, a comprehensive water security department will dredge sewers, and the frequency is higher than usual. The reason why winter is to focus on cleaning up drains, because of low winter temperatures, hotel quality effluent from CNPC will quickly condense, not how long it will accumulate in the pipeline. With the accumulation of oil pipeline will become more and more detailed, and oil will be stranded in other things, getting smaller and smaller role in making the sewers. "Sewage pipe blocked, not all regions are true, but the restaurant industry is definitely where intensive" hardest hit "because oil solidified clogged sewer. Because many restaurants with no grease trap grease traps or construction does not meet the standard, leading with oily wastewater directly discharged into the sewage pipe in Lanzhou stainless steel grease trap, clogging becomes commonplace. "do not follow the construction of Xi'an stainless steel grease trap grease trap is an important cause of clogged sewer, but is not the only factor. Even the construction of a grease trap, but if you do not clean up, can also cause sewer blockages. "2. Canteen and restaurant business oily wastewater, shall be subject to permit oil removal device into sewers behind the grease trap surface advection generally set cover, except for winter to keep the temperature of scum, so as to maintain its liquidity outside , but also can fire and rain in cold areas should be set up in the pool heating pipe buried grease traps for heating when necessary. advection grease trap is characterized by simple structure, easy operation and management, water separator effect is stable. Data show grease, grease trap can be removed advection smallest droplet diameter is 10 0 ~ 150um, the corresponding increase in speed is not higher than 0.9mm / s. (Figure 2-20) shows the swash plate grease pool. grease trap of this type separable minimum droplet diameter of about 60um, a corresponding increase in speed of about 0.2mm / s. swash plate type oil-water residence time in the grease trap is not more than 30min, the advection grease trap 1/4-1/2.
