Background technology

Currently, water environment in China protection faces very big pressure, the treatment technology of sewage is in urgent need to be improved, sewage disposal and harmless Change and processing water recycles situation, is directly related to the strategy of sustainable development of the people's livelihood and national economy.Sewage disposal ring The progress of guarantor's technology has extremely important economic value and political significance.

Modern sewage and waste water processing method at present, is broadly divided into physical treatment process, method of chemical treatment and biological treatment Three classes.

Physical treatment process is to be detached by the method for physical action, recycle the undissolved dirt in suspended state in waste water The waste water logos for contaminating object (including oil film and oil droplet), can be divided into gravitational separation process, centrifugal separation and sieving retention method etc..

Method of chemical treatment is detached, is removed in waste water in dissolving, colloidal state by chemical reaction and effect of mass transmitting Pollutant or the waste water treatment process for being translated into innocuous substance.Method of chemical treatment generates chemical reaction as base to add medicament Plinth is the processing procedure with principles of chemistry such as coagulation, neutralization, redox.

Biological treatment is the metabolism by microorganism, makes to be in solution, colloid and fine suspended state in waste water Organic pollution, be converted into stablize, the waste water treatment process of harmless substance.

In sewage treatment field, especially in the oil field extracted water separation field of oil extraction in oil field, the most of oil in China Field, with the growth in oilfield exploitation age, the moisture content that well recovery goes out liquid constantly rises, and the Produced Liquid water content of oil recovery exists 90% or so, annual huge crude output covers huge extraction liquid measure, to generate the oil field extracted water of flood tide, flood tide Oil field extracted water require to carry out water-oil separating and harmless treatment.

In the oil extraction in oil field production in China, it is substantially all the water drive oil method that use to the stratum reinjected water of underground, Oil field is offered to required flood tide oil reinjection water every year.After these oil field produced water process, reach the standard of reinjected water, Have become the water source of the main oil reinjection water in oil field.

Oil field extracted water is handled, many indexs such as suspended matter, crude oil, bacterium in water is strictly controlled, prevent it Stratum is generated and destroys and injures.

In some areas, oil field extracted water will drain into rivers after harmless treatment, then have to according to country and ground Square environmental legislation requirement, processing oil field extracted water reach the environmental standard of emission request.Some arid areas of China, there is a serious shortage of Water resource will turn waste into wealth after the large amount of sewage generated in oil recovery process processing, be used for industrial and agricultural production, have highly important Real value.
