Along with the fast development of petroleum chemical industry, be in the course of processing of raw material with the oil, the oily(waste)water of generation is more and more.This factory effluent water quality changes with the difference of refinery process for processing device, water displacement is big, and the organic content height contains oil content, more containing a large amount of toxic substance (as methylethylketone, toluene and ammonia etc.), is difficult processing and the bigger organic property trade effluent of harm.
Oil in the oily(waste)water generally is present in the water with three kinds of states:
⑴ but oil slick: the oil product particle diameter is bigger, generally greater than 15 μ m, is easy to bubble through the water column and can skim, and he is the major portion of oleaginousness in the waste water, generally accounts for 65% ~ 70% of oleaginousness in the waste water.But the normal means such as dragging for left-falling stroke that adopt of oil slick are removed in oil trap.
⑵ dissolving oil: it is the oil content less than the oil in water emulsion particle diameter, and majority is a dissolved hydrocarbons oil, and the solubleness in water is very little, generally is about 5 ~ 15 mg/L, adopts biochemical process to remove more.
⑶ oil in water emulsion: oily(waste)water is cut by turbomachine in course of conveying, or pressure reduces suddenly or has a tensio-active agent, oil is emulsified state in water, form oil in water emulsion, the oil product particle diameter is less than 15 μ m, system is more stable, is difficult for floating on the water surface, generally adopts methods such as flotation, filtration, flocculation to remove.
Its harm mainly shows the following aspects:
Because it is waterborne that the oily substance that is insoluble in water swims in, and stops the dissolving of airborne oxygen in water, cause the biological death by suffocation of water body, hinder hydrobiological photosynthesis, thereby influence the self-purification of water body, worsen water quality, endanger aquatic resources.Influence health and the living environment of near the animal in waters, the birds surface is stained with oil spilling, can lose flight performance, even dead, and animal has been drunk oily(waste)water, might infect fatal diseases.Hazardous and noxious substances will be detrimental to health by food chain by enrichments such as fish, shellfishes.Indirect hazard atmosphere and soil.
