Problems solved by technology
[0002] Domestic sewage refers to the wastewater discharged by people in daily life activities. This wastewater is mainly polluted by domestic waste and human excrement. The quantity, composition and concentration of pollutants are related to people's living habits and water consumption. Domestic sewage Generally, it does not contain toxic substances, but it has conditions suitable for the reproduction of microorganisms, contains a large number of bacteria and pathogens, and is harmful to a certain extent from a hygienic point of view.
[0003] Due to the continuous increase of urban population, the problem of urban domestic wastewater treatment has become increasingly prominent, and because of backward technology, shortage of funds, and difficulty in governance, it has always affected the urban environment and its construction. With the continuous increase of water consumption, the pollution will be more serious and the impact will be worse

The invention discloses a device and a method for decomposing grease on the outer surfaces of particles in organic wastewater, and belongs to the field of wastewater treatment. A proper amount of organic wastewater can be injected into a filter tank through a water inlet; large impurities and garbage on the surface and at the bottom of the filter tank are fished out in advance; a placing plate anda sealing cover are sequentially placed in a fixed plate; the sealing cover is opened before the placing plate is placed; calcium oxide is filled in the placing plate; the fixed plate is mounted at the water outlet; organic waste water sequentially passes through a fixing frame and the placing plate and is filtered, when an auxiliary filter screen is blocked due to viscosity of grease at the outer ends of particles, water pressure applies pressure to the upper end of the auxiliary filter screen, a sliding ring slides downwards, the wastewater reacts with calcium oxide to generate heat, the grease is melted, and the filtering efficiency is improved.
