Abstract
The invention discloses a sewage disposal process, by combining sediment preprocessing, anaerobic treatment, an anaerobic aerobiotic coupling process, flocculation treatment and the like, the process is simple, good in effect, high in decolourization ratio, COD and BOD removal rate, and phosphorus removal rate, small in solid residue, low in cost and suitable for popularization.
Description
Technical field
The present invention relates to a sewage water treatment method, particularly a kind of sewage treatment process.
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.
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, 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) by draining into anaerobic fixed film reactor through sedimentation sewage and carry out anaerobic treatment in settling pit,
(3) the abundant chain rupture of pollutent macromolecular chain that the anaerobic bacterium in active sludge makes in sewage is utilized, fast degradation organism
(4) sewage processed through anaerobic zone is sent into aerobic zone to process, and carry out Air Exposure at aerobic zone increase aerating apparatus;
(5) water after Air Exposure, sends into flocculation tank and carries out flocculation treatment;
(6) add flocculation agent at flocculation tank, the process water after coagulation for phosphorus removal enters flocculation tank, makes all colloidal solids in process water complete flocculation;
(7) the process water through flocculation is filtered by the fiber filtering of fibre turntable filter chamber.
As a modification of the present invention, the composition of described flocculation agent is: the aluminium hydroxide of 5-8 weight part, the polymerize aluminum chloride of 8-12 weight part, the sodium metaaluminate of 12-18 weight part, the ironic citrate of 5-10 weight part, the bodied ferric sulfate of 5-10 weight part, the Na2Fe04 of 6-8 weight part.
Beneficial effect:
Sewage treatment process of the present invention, by precipitation pre-treatment, anaerobic treatment, aerobic-anaerobic coupling technique, and the combining of the step such as flocculation treatment, its technique is simple, effective, percent of decolourization, COD, BOD clearance, tp removal rate is high, 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 kind of sewage treatment process, 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) by draining into anaerobic fixed film reactor through sedimentation sewage and carry out anaerobic treatment in settling pit,
(3) the abundant chain rupture of pollutent macromolecular chain that the anaerobic bacterium in active sludge makes in sewage is utilized, fast degradation organism
(4) sewage processed through anaerobic zone is sent into aerobic zone to process, and carry out Air Exposure at aerobic zone increase aerating apparatus;
(5) water after Air Exposure, sends into flocculation tank and carries out flocculation treatment;
(6) add flocculation agent at flocculation tank, the process water after coagulation for phosphorus removal enters flocculation tank, stops more than 12-20min, is stirred, make all colloidal solids in process water complete flocculation by stirrer;
(7) the process water through flocculation is filtered by the fiber filtering of fibre turntable filter chamber.
As a modification of the present invention, the composition of described flocculation agent is: the aluminium hydroxide of 5-8 weight part, the polymerize aluminum chloride of 8-12 weight part, the sodium metaaluminate of 12-18 weight part, the ironic citrate of 5-10 weight part, the bodied ferric sulfate of 5-10 weight part, the Na2Fe04 of 6-8 weight part.
Sewage treatment process of the present invention, by precipitation pre-treatment, anaerobic treatment, aerobic-anaerobic coupling technique, and the combining of the step such as flocculation treatment, its technique is simple, effective, percent of decolourization, COD, BOD clearance, tp removal rate is high, solid residues amount is little, and with low cost, is applicable to promoting.
Sewage after aforesaid method process, percent of decolourization is 96.8%, COD clearance 87.5%, BOD clearance is 79.8%, total tp removal rate 97.7%, total ammonia clearance 63.2%, 20 microns of solid substance residual rates 18.6%, flocculation agent residual rate 12.6%.
