Abstract
The invention discloses a high-grease sewage treatment process. The treatment process comprises steps of pretreatment, collection of grease, aeration treatment and the like. The high-grease sewage treatment process is simple in process, good in effect, high in decolorization rate and grease contamination removal rate, high in COD and BOD removal rate, high in phosphorus removal rate, less in solid residue, low in cost and suitable for being popularized.
Description
Technical field
The present invention relates to a sewage water treatment method, particularly a kind of sewage treatment process of high grease.
Background technology
Along with China's industrial development, create a large amount of industrial sewage and sanitary sewage, pollution on the environment impact more and more comes obviously.The highly difficult sewage wherein discharged, as chemical engineering sewage, petrifaction sewage, coked waste water, percolate, pharmacy sewage, plating cyanogens-containing sewage water, grinding sewage etc., containing a lot of refractory organic and bio-toxicity material in these sewage, organic components is complicated, chemical oxygen demand COD concentration is high, and this type of sewage is very difficult.In recent years, there have been a lot of research and technological development in China in highly difficult field of sewage treatment, but corresponding environmental protection task is still very arduous.
Especially for the sewage that oleaginousness is high; in in this type of sewage, not only the content of oil slick, oil in water emulsion and dissolving oil is high; but also can mix and have a large amount of suspended organic matters; and usually can contain the material of the degradation property differences such as phenol, aldehyde, alcohol, alkane, halohydrocarbon in above-mentioned suspended organic matter composition, therefore substantially increase the intractability of the high sewage of oleaginousness.
Summary of the invention
It is simple that the object of the invention is to provide a kind for the treatment of process, treatment effect good and with low cost sewage water treatment method.
For achieving the above object, the method that the present invention adopts is: a kind of sewage treatment process of high grease, comprises following step:
(1) adopt sump pump by the thick solid sundries of sewage in grid decontamination water, then sewage is sent in settling pit and carry out precipitation process;
(2) in sewage, pass into air, make to produce bubble in water, the oil droplet be dispersed in water is bonded on bubble, floats on the surface of the water with gas, and with filter screen collection gently;
(3) sewage is sent in aeration and biological pond and carry out process and carry out Air Exposure;
(4) water after Air Exposure, sends into flocculation tank and carries out flocculation treatment;
(5) add flocculation agent at flocculation tank, the process water after coagulation for phosphorus removal enters flocculation tank, is stirred by stirrer, makes all colloidal solids in process water complete flocculation;
(6) the process water through flocculation is filtered by the fiber filtering of fibre turntable filter chamber.
Beneficial effect:
The sewage treatment process of high grease provided by the invention, its technique is simple, effective, percent of decolourization, and oily waste degradation rate is high, COD, BOD clearance, and tp removal rate is high, and solid residues amount is little, and with low cost, is applicable to promoting.
embodiment:
Below in conjunction with specific embodiment, the present invention is further described;
Embodiment 1:
A sewage treatment process for high grease, comprises following step:
(1) adopt sump pump by the thick solid sundries of sewage in grid decontamination water, then sewage is sent in settling pit and carry out precipitation process;
(2) in sewage, pass into air, make to produce bubble in water, the oil droplet be dispersed in water is bonded on bubble, floats on the surface of the water with gas, and with filter screen collection gently;
(3) sewage is sent in aeration and biological pond and carry out process and carry out Air Exposure;
(4) water after Air Exposure, sends into flocculation tank and carries out flocculation treatment;
(5) add flocculation agent at flocculation tank, the process water after coagulation for phosphorus removal enters flocculation tank, is stirred by stirrer, makes all colloidal solids in process water complete flocculation;
(6) the process water through flocculation is filtered by the fiber filtering of fibre turntable filter chamber.
The sewage treatment process of high grease provided by the invention, its technique is simple, effective, percent of decolourization, and oily waste degradation rate is high, COD, BOD clearance, and tp removal rate is high, and solid residues amount is little, and with low cost, is applicable to promoting.
