Background
Sewage refers to effluent water from life and production that is contaminated to some extent. The water which loses the original use function is called sewage for short. Mainly used water in life, which contains more organic matters and is easy to treat.
Sewage may be defined as a waste-laden liquid or water mixed with ground water, surface water, snow storms, etc. discharged from residential, institutional, commercial or industrial areas from the point of view of the source of the sewage. Sewage is classified into many categories, and there are many techniques and processes for reducing the environmental impact of sewage accordingly. Sewage can be classified into these four categories according to the source of the sewage.
The first type: industrial wastewater is derived from sewage from manufacturing mining and industrial production activities, including runoff leachate from industrial or commercial storage, processing, and other wastewater that is not domestic sewage.
The second type: domestic sewage is sewage from a house, an office building, an office or the like; sanitary sewage; sewage water, including industrial waste water mixed in domestic sewage water in a sewer system. Garbage, various atmospheric particulates, and the like, which enter the water environment through surface runoff, soil erosion, farmland drainage, and the like. The method has the characteristics of dispersity, concealment, randomness, latency, accumulation, ambiguity and the like, so that the method is difficult to monitor and quantify, and the difficulty of research, prevention and control is high. The discharge of water pollutants into the body of water causes the substances of pollution.
In the third category: commercial sewage comes from commercial facilities and some components exceed the non-toxic, harmless sewage of domestic sewage. Such as restaurant sewage. Laundry sewage, animal feeding sewage, sewage generated by a hair salon, and the like.
The fourth type: surface runoff comes from rain, snow, highway sewage, water from urban and industrial areas, etc., and surface runoff does not seep into the soil and enters groundwater along streets and lands.
The general industrial sewage usually contains oil stain, and because sewage is treated, the process of introducing the sewage into a sewage tank continuously generates impact fluctuation of a liquid level, so that a plurality of small oil drops can be doped and sink in the sewage instead of floating on the surface of the sewage.
