Abstract
The invention provides a technological method for advanced sewage treatment. The technological method is characterized by comprising steps as follows: (1) sewage is led into a mixer, a proper amount of a coagulant is added to the mixer to be stirred, and smaller alum floccule is formed; (2) a mixed liquid is led into a flocculation mixer, a proper amount of a flocculant is added to be stirred, floccule is formed, and the alum floccule becomes heavier; (3) a flocculated liquid is led into a concentration sludge scraper for precipitation, heavier alum floccule precipitates and is discharged together with sludge, lighter alum floccule are adsorbed on an inclined plate in the sludge scraper, clear water in a precipitation tank is collected by the aid of a water collection tank, and then the clear water is obtained. The technological method can be conveniently implemented in cooperation with a device in the high-density precipitation tank, the reaction time is short, and the clear water rate is high.
Description
Technical field:
The present invention relates to a kind of processing method of deeply treating wastewater, belong to field of environmental engineering.
Technical background
Along with socioeconomic high speed development, living standards of the people improve constantly, and town and country water consumption increases gradually, and pollute more and more serious.But available soil, town and country is fewer and feweri, the sewage drainage standard of country's formulation is simultaneously also more and more stricter.Utilize contact flocculation principle to remove the settling pond of suspended substance in water, before a century, just started application in the world, but long reaction time, clear water rate are out low.
Summary of the invention
In order to solve the problems of the prior art, technical solution of the present invention is: a kind of processing method of deeply treating wastewater, is characterized in that: the step of this processing method is as follows:
(1) sewage is introduced in mixing and blending machine, in mixing and blending machine, add appropriate coagulating agent, then stir, form less alumen ustum;
(2) mixed liquid is introduced in flocculation stirring machine, add appropriate flocculation agent and stir, form flocs unit, make alumen ustum become heavy;
(3) precipitate in the liquid introducing concentrated mud scraper after flocculation, precipitated by heavy alumen ustum, together get rid of with mud, lighter alumen ustum is adsorbed on the swash plate in mud scraper, clear water in settling tank is collected by water leg, obtains the water clarified afterwards.
Described coagulating agent is inorganic salts, preferably aluminium salt or molysite.
Described flocculation agent is polyacrylamide copolymer.
Processing method of the present invention can coordinate the device in a kind of potassium permanganate composites to operate, and the method is easy to operate, and the reaction times is few, and clear water rate is high.
Embodiment
Below in conjunction with specific embodiment, technical scheme of the present invention is described.
