Brick concrete, steel concrete or carbon steel can be used. Anti-corrosion epoxy resin coating is used in combination with chemical fiber fabrics. Generally, if the requirements are not high, it will be 1 cloth and 2 oils for 3 cloths and 4 oils. If the requirements are high, it will contain a large amount of acid and alkali or other corrosive substances, use 5 cloths and 6 oils. Oil removal efficiency is closely related to residence time and water distribution structure. If the requirements are not high, brick concrete can be used. If the requirements are high, steel concrete can be used. If the water volume is low. efficiency requirements are high, carbon steel structure is required.
Grease trap: It uses the different densities of suspended solids and water in the wastewater to achieve the separation objective. The strGrease trap ucture is mainly advection type, and the oily wastewater enters the oil trap with a rectangular plane through the water distribution tank. The pool flows slowly in the horizontal direction. The oil floating on the flow surface is pushed to the oil collection pipe by the oil collection pipe or oil scraper installed on the pool surface and flows into the dehydration. reservoir.
It is deposited in the oil trap. Heavy oil and other impurities accumulate in the sludge hopper at the bottom of the pool and enter the sludge pipe through the sludge discharge pipe. The waste water after oil separation overflows. drainage channel and discharge pool for further treatment to remove emulsified oil and other impurities. The grease trap is equipped with two oil drains on the left and right according to the actual conditions of the place of ininstallation, one side can be closed and. one side can be closed. When using the oil drain port on one side, a valve must be installed. When changing the oil, open the valve if necessary. The water outlet can be temporarily closed to increase the oil level and drain the oil. floating oil.
You can also open the pool cover and skim off the grease with a spoon. The grease trap is equipped with a stainless steel filter, which has a good grill function and can effectively trap plant residue and debris. when they are discharged into the grease trap. Simply use a strainer to fish them out.
If there is too much grease on the filter, you can remove the filter and rinse it once with hot water. then put it back in place. Depending on use, if the surface grease in the grease trap exceeds 5 cm, the oil should be drained. There are two drain outlets at the bottom of the grease trap, whichi need to be closed after installing one. Valve. Clean the grease trap thoroughly. The valve can be opened to drain all the water and mud at the bottom of the grease trap.
Grease traps are divided into overhead, underground and semi-buried. , Suspended, automatic oil scraping and grease trap, air floating automatic oil scraping and grease trap, filter type grease trap
