More preferably, described filter screen 36 is slope shape and is provided with arc buffering portion at lower slope section, and impurity is arrived, and lower slope section also can more easily be washed open, prevents from piling up, and manually keeps an eye on without the need to configuring.
The enforcement of above-mentioned Sewage treatment systems, be a kind of sewage treatment process using above-mentioned Sewage treatment systems, it comprises the following steps:
S1, waste water enter water collecting basin 11, and preliminary sedimentation removes the insoluble substance such as coarse wool bits, hair slag, lime sand grains in water; Achieve preliminary filtration, be settled out slightly heavy impurity and insoluble impurities.
S2, waste water enter strainer filtering device 13 through water collecting basin 11 overflow or pump suction, by strainer filtering, suede slag are separated with water; Thus bubble through the water column lighter or suspend and the partial impurities filtering of water quality, as eider down etc.
S3, waste water flow into acidification pool 14, microorganism pond 15, micro-pore aeration pond 16 successively, acidification pool 14 and inside, micro-pore aeration pond 16 make it form longer water stream channel by spaced walls, by vertically arranging hairbrush at water stream channel, make the waste water acidifying of sluggish flow, under for the waterplant of biological tank and attached probiotics and secondary bacterium effect thereof, dirt is adsorbed and metabolism purification; Waste water makes its acidifying form the environment of applicable microorganism growth at acidification pool 14, and wherein pH value to control between 5.8 to 8.6 and consumes part nutrient, and this nutrient comes from the impurity in sewage.Then the sewage after acidifying is introduced microorganism pond 15 and remove partial impurities with carrying out primary stance environmental protection.
Hairbrush in micro-pore aeration pond 16 carries out aeration agitation to waste water, turns out the objectionable impurities in microbial decomposition waste water; Then enter micro-pore aeration pond 16 to make not remove impurity and form a team further and grow up, be convenient to post precipitation and filter.
S4, waste water flow into multifeed clarifier 17, and namely multiple settling tank carries out stationary stream and slowly precipitates; Waste water precipitates at multifeed clarifier 17, by under contamination precipitation in stationary stream process, eventually passes husky filter and is stoped among layer of sand by unprecipitated impurity, complete sewage disposal.
The overflow after multi stage precipitation of S5, waste water forms certain level pressure to water level pond 79, then establish the strainer tube 82 of filter bowl 85 or filter cloth 86 in injecting and the water vent 88 offered on the upside of strainer tube 82 sprays and then falls into sand filter 18, and discharged by sand filter 18; Strainer tube 82 and layer of sand can do further depth type filtration to sewage, and the basic filtering of detrimental impurity, nutritive substance has also been absorbed and used in treating processes.
The vegetation garden, marsh that the water of S6, discharge drains into side is irrigated, and excessive from the husky wall infiltration of the surrounding underground of a week in vegetation garden, marsh, and then is discharged into the external world.The water quality standard of the tail water obtained through sewage treatment step above can direct reuse in production, also can be further purified through biological Swampy Areas and from soil, enter underground, form underground water, realize infiltration type discharge.Therefore sand filter 18 can be filtered the water drainage of oozing out out and biological Swampy Areas are set as its most downstream.
The mud precipitated in S7, water collecting basin, acidification pool, micro-pore aeration pond, multifeed clarifier is delivered to sludge thickener, and becomes mud cake by sludge dewatering equipment press dewatering, and mud cake has many fertilizer nutrients, can the dry rear fertilizer being used as plant growing.
More preferably, the water that wherein sludge dewatering equipment squeezing is deviate from is drained in microorganism pond, and the sewage being about to extruding discharge processes, and avoids sewage directly to put external connection row.
Above disclosedly be only the preferred embodiments of the present invention, certainly can not limit the interest field of the present invention with this, therefore according to the equivalent variations that the present patent application the scope of the claims is done, still belong to the scope that the present invention is contained.
