Technical Field
The invention relates to the field of sewage treatment, in particular to a high-efficiency continuous treatment method for semi-free desorption type liquid level oil stains.
Background
Sewage is the effluent 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 divided into these two categories according to the source of the sewage.
The first type is industrial wastewater: 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 is domestic sewage: sewage from homes, office buildings, offices, 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. Water pollutants (Waterpollutant) are the substances that cause pollution when discharged into a body of water.
Contain the greasy dirt in the sewage, because water oil layering, and the greasy dirt floats the nature on the surface of water, prior art floats adsorption material usually and carries out the absorption of greasy dirt on the surface of water, the desorption need be retrieved to the adsorption material after the greasy dirt absorption, later throw into and carry out the greasy dirt absorption again in the sewage, however this kind of mode, comparatively consume time to the recovery of adsorption ball, and can cause certain interruption to sewage treatment's process, make and to have certain influence to the absorbent holistic efficiency of greasy dirt.
