Description

A kind of sewage treatment process of high oil mass
Technical field
The present invention relates to a sewage water treatment method, in particular to a kind of sewage treatment process of high oil mass.
Background technique
With China's industrial development, a large amount of trade effluents and sanitary sewage are produced, pollution on the environment influence is got over Come more next obvious.The highly difficult sewage wherein discharged, such as chemical engineering sewage, petrifaction sewage, coked waste water, landfill leachate, pharmacy Sewage, plating cyanogens-containing sewage water, grinding sewage etc., contain many refractory organics and bio-toxicity object in these sewage Matter, organic components are complicated, and COD COD concentration is high, and such sewage is very difficult.In recent years, China is highly difficult Field of sewage treatment has many researchs and technological development, but corresponding environmentally friendly task is still very arduous.
Particularly with the sewage that petrochemical industry processing generates, in such sewage in not only oil slick, oil emulsion and dissolved oil content Height, but also a large amount of suspended organic matter can be contaminated with, and in above-mentioned suspended organic matter ingredient usually can containing phenol, aldehyde, The substance of the degradabilities such as alcohol, alkane, halogenated hydrocarbons difference, therefore substantially increase the processing difficulty of the high sewage of oil content.
Summary of the invention
The invention aims to solve the above problems, a kind of sewage treatment process of high oil mass is provided.
In order to achieve the above objectives, the method that the present invention uses is: a kind of sewage treatment process of high oil mass, including following Step:
(1) using sewage pump by sewage through the coarse solid sundries in grid decontamination water, then by sewage be sent into setting pot in into Row precipitation process；
(2) sewage in sedimentation basin is sent into aeration and biological pond and is handled；
(3) it will handle by treated in aeration and biological pond sewage being sent into anaerobic pond；
(4) sewage crossed through Anaerobic Treatment is sent into anoxic zone and carries out anoxic treatment；
(5) sewage is sent into flocculation tank and is handled, add flocculant, flocculant usage is sewage 200- per ton 280g makes to handle a large amount of colloidal solids in water and completes flocculation；
(6) after the sewage in step (5) after flocculating being carried out secondary precipitation, and sediment is separated by cyclone separator；
(7) sewage of step (6) separation is being passed through into adsorption treatment, activated coke, and filling in blender is added in adsorption tank Divide under stirring and comes into full contact with the water outlet after the activated coke and biochemical treatment of powder shape；
(8) passing through step (7), treated by the filtering of filler filter layer.
As an improvement of the present invention, the ingredient of the flocculant are as follows: the ferric sulfate of 5-12 parts by weight, 10-15 weight Measure the ferric trichloride of part, the ferrate of 5-10 parts by weight；Polyacrylamide, gelatin, the soluble cellulose of 8-15 parts by weight Mixture.
The utility model has the advantages that
The present invention is handled by the bio-aeration for carrying out gradation in batches to the high trade effluent of oil content, pre-processed by precipitating, Anaerobism coupling technique and flocculation treatment and etc. combine, simple process, effect is good, percent of decolourization, oily waste degradation rate Height, COD, BOD removal rate, tp removal rate is high, and solid residues amount is small, and low in cost, is suitble to promote.
Specific embodiment:
Below with reference to specific embodiment, the present invention is further described；
Embodiment 1:
A kind of sewage treatment process of high oil mass, comprises the following steps that
(1) using sewage pump by sewage through the coarse solid sundries in grid decontamination water, then by sewage be sent into setting pot in into Row precipitation process；
(2) sewage in sedimentation basin is sent into aeration and biological pond and is handled；
(3) it will handle by treated in aeration and biological pond sewage being sent into anaerobic pond；
(4) sewage crossed through Anaerobic Treatment is sent into anoxic zone and carries out anoxic treatment；
(5) sewage to be sent into flocculation tank and is handled, add flocculant, flocculant usage is dirt 200-280g per ton, Make to handle a large amount of colloidal solids in water and completes flocculation；
(6) after the sewage in step (5) after flocculating being carried out secondary precipitation, and sediment is separated by cyclone separator；
(7) sewage of step (6) separation is being passed through into adsorption treatment, activated coke, and filling in blender is added in adsorption tank Divide under stirring and comes into full contact with the water outlet after the activated coke and biochemical treatment of powder shape；
(8) passing through step (7), treated by the filtering of filler filter layer.
The ingredient of above-mentioned flocculant are as follows: the ferric sulfate of 5-12 parts by weight, the ferric trichloride of 10-15 parts by weight, 5-10 weight Measure the ferrate of part；The polyacrylamides of 8-15 parts by weight, gelatin, soluble cellulose mixture.
