Abstract

The invention discloses a kind of processing methods of sanitary sewage, including by sewage through the coarse solid sundries in grid decontamination water, then sewage is sent into setting pot and carries out precipitation process, then it carries out aerobic treatment process, then handled again by biofilm packing layer, it is measured in real time finally by the water tank to drainage position, can guarantee that the sewage of processing can reach discharge standard.

Description

A kind of processing method of sanitary sewage
Technical field
The present invention relates to a sewage water treatment method, in particular to a kind of processing method of sanitary sewage.
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.
Summary of the invention
It is an object of the present invention to provide a kind of processing method is simple, at high treating effect and low-cost sanitary sewage Reason method.
In order to achieve the above objectives, the method that the present invention uses is: a kind of processing method of sanitary sewage, including following step It is rapid:
(1) use sewage pump that sewage through the coarse solid sundries in grid decontamination water, is then sent into setting pot by sanitary sewage Middle carry out precipitation process；
(2) sewage precipitated through sedimentation basin is promoted in biological contact oxidation pond by sewage pump and carries out biochemical treatment；
It (3) will be through step (2) processed sewage through carrying out degradation purification again in biofilm packing layer；
(4) secondary heavy pond is flowed into through treated in step (3) water, is removed by precipitating through aerobic and through biological film process The sludge of generation obtains clear processing water；
(5) the processing water after secondary precipitation flows into the coagulating basin of addition coagulant, 20-30min is stopped in coagulating basin；
(6) it will be sent by water pump into catalyst reaction tower and handled by the sewage of coagulating basin processing；
(7) it is sent into water tank by the processed sewage of catalyst reaction tower, and detection mouth is set in water tank, detection is qualified Sewage be discharged by the discharge outlet of water tank, underproof sewage is sent into step (6) and is handled.
The utility model has the advantages that
Domestic sewage treatment process of the invention can be improved at sewage by precipitating pretreatment, oxidation processing technique The ability of reason, at the same also can to treated, sewage is measured in real time, guarantee processing sewage can reach discharge mark It is quasi-.
Specific embodiment:
Below with reference to specific embodiment, the present invention is further described；
Embodiment 1:
A kind of processing method of sanitary sewage, comprises the following steps that
(1) use sewage pump that sewage through the coarse solid sundries in grid decontamination water, is then sent into setting pot by sanitary sewage Middle carry out precipitation process；
(2) sewage precipitated through sedimentation basin is promoted in biological contact oxidation pond by sewage pump and carries out biochemical treatment；
It (3) will be through step (2) processed sewage through carrying out degradation purification again in biofilm packing layer；
(4) secondary heavy pond is flowed into through treated in step (3) water, is removed by precipitating through aerobic and through biological film process The sludge of generation obtains clear processing water；
(5) the processing water after secondary precipitation flows into the coagulating basin of addition coagulant, 20-30min is stopped in coagulating basin；
(6) it will be sent by water pump into catalyst reaction tower and handled by the sewage of coagulating basin processing；
(7) it is sent into water tank by the processed sewage of catalyst reaction tower, and detection mouth is set in water tank, detection is qualified Sewage be discharged by the discharge outlet of water tank, underproof sewage is sent into step (6) and is handled.
Domestic sewage treatment process of the invention can be improved dirt by precipitating pretreatment, oxidation processing technique The ability of water process, at the same also can to treated, sewage is measured in real time, guarantee processing sewage can reach row Put standard.
