Embodiment
The present invention is further described below in conjunction with drawings and Examples;
As illustrated in fig. 1 and 2, the less energy-consumption treatment process of one way of life sewage, its processing step is: sewage at first enters regulates the acidifying district, then enter biochemical precipitation process district by being provided with pipeline aerator 4 between adjusting acidifying district and the biochemical precipitation process district, enter again artificial filter tank district, last qualified discharge.Described sewage passes through water pump 5 with the water extraction liter after regulating the processing of acidifying district, on the outlet conduit of water pump 5, be flexibly connected pipeline aerator 4 by PP, sewage enters biochemical precipitation process district by pipeline aerator 4, and the level attitude of regulating acidifying district, biochemical precipitation process district and artificial filter tank district three reduces by 10～15cm successively.
Regulate in the acidifying district and be provided with water quality and quantity regulatory function unit 11 and acidication unit 12, water quality and quantity regulatory function unit 11 comprises cloth tank 111 and cloth waterwall 112, sewage enters water quality and quantity regulatory function unit 11 by water inlet pipe 113, through flow deflector 114 water conservancy diversion, pass cloth waterwall 112 and finish balanced water quality and quantity adjusting, enter acidication functional unit 12 by flow deflector 114 water conservancy diversion again, dividing plate 121 is shorter, sewage did not have dividing plate 121 beginning acidified degradations, again by training wall 122, the sewage on upper strata enters aqua storage tank 125 by exporting 123, lower floor's sewage refluxes by return line 124, water pump 5 in the aqua storage tank 125 makes sewage enter biochemical precipitation process district by pipeline aerator 4 the water extraction liter; By acidication unit 12, the organic macromolecule mass degradation in the sewage becomes small molecule organic compound, and the organic volumetric loading in the sewage has reduced, part pollutent and moisture from and preliminary degraded, realized the phase transition of part pollutent.
Biochemical precipitation process district comprises that biochemical unit 21 and precipitation leave standstill unit 22; The sewage of preliminary degraded enters biochemical unit 21, the microbial film 211 that has in sewage and the biochemical unit 21 fully contacts, but the sheet ecological matrix that has the efficient degradation microorganism on the microbial film 211, synergy by biology, physics and chemistry, sewage is further degraded, sewage after the degraded enters after precipitation leaves standstill unit 22, and lower floor's sewage refluxes by reflux line 221, and upper strata sewage enters artificial filter tank district by pipeline.
Artificial filter tank district comprises a pond 31 and two ponds 32,31 middle parts, one pond have filter 311, the bottom is floating stuffing 312, after sewage enters floating stuffing 312 aftertreatments by filter 311, enter two ponds 32, two ponds 32 are vegetable layer 321, filter material layer 322, supporting layer 323 and impervious barrier 324 from top to bottom, have the sewage of the being convenient to Flowing Space that makes progress between supporting layer 323 and the impervious barrier 324; Sewage is L-type by the pipeline 325 that a pond 31 enters two ponds 32, pipeline 325 imports filter material layer 322 with sewage, the lower end of described pipeline 325 has equally distributed water outlet, the biological particles layer of filter material layer 322 for having adsorptivity, filtration through filtrate, organic substance in the sewage is by the degraded of microorganism efficient biochemical and absorption, and last qualified discharge is to clean water basin 326.
The present invention is provided with pipeline aerator 4 between adjusting acidifying district and biochemical precipitation process district, therefore, in biochemical precipitation process district, there is not aerating apparatus, aeration aerating is that the sewage lifting in regulating the acidifying district is finished in the process in biochemical precipitation process district, this process, changed traditional non-processor theory, directly save 1/2 of running cost, indirect saving handling cost 1/3, simultaneously, in biochemical precipitation process district 2, carry out stable, the compatible and assimilation of mud, realized degraded and the water body purification of pollutent.
