Description
Technical field
The utility model relates to a kind of Waste Water Treatment, particularly relates to a kind of oil-contained waste water treatment system.
Background technology
Along with developing rapidly of industry, the trade effluent produced in industrial production discharges in a large number, also increasingly extensive and serious to the pollution of water body, threatens the health and safety of the mankind.For protection of the environment, the process of trade effluent is more even more important than the process of municipal effluent.Wherein oily(waste)water accounts for ratio larger in trade effluent, in the industrial operation of the industries such as oil, petrochemical complex, iron and steel, coking, gas generating station, mechanical workout, all can produce oily(waste)water.If oily(waste)water is not recycled, waste can be caused; Enter river, lake or bay, meeting polluted-water, affect hydrobiont existence; For agricultural irrigation, then can block interstices of soil, hinder crop growth.
But the composition of oily(waste)water is not single, adds the difficulty of process.Wherein pollution by oil material, except the relative density of tar heavy oil is comparatively large, remaining relative density is all less than 1.Oily substance in waste water usually floatingly to oil, dispersed oil and oil in water emulsion three kinds of states exist.Wherein float and oil, blob volume is comparatively large, is easy to separate from waste water; The oil droplet size of dispersed oil is placed in the middle, suspends in water; The oil droplet size of oil in water emulsion is less, and the particle diameter that oil product disperses in waste water is very little, in emulsified state, not easily separates from waste water.
The useless oil percentage in water of discharging due to different industrial sector is widely different, therefore, in the technique means of present process oily(waste)water, administering oily(waste)water is utilize oil trap mostly, the oily(waste)water produced is after sedimentation oil removal, by the surperficial oil slick manually fished for, skimming or heavy oil, processing efficiency is 60% one 80%; Oil in water emulsion in waste water and dispersed oil more difficult.The oil slick reclaimed or heavy oil, mostly unified by specifying recovery unit to reclaim, recycle after again purifying; And the direct discharging of waste water after deoiling, water resources does not repeat reuse, does not meet the requirement of cleaner production.
There is fluid purification efficiency in prior art not high, waste water is not clean to be reclaimed, and adds production cost, wastes public resource.
Utility model content
