Background technology
At present, along with progress and the socioeconomic development of human civilization, the mankind the most progressively recognize that environmental conservation is to promoting social progress and the significance of economic sustained, stable and coordinated development.Environmental protection work has become our fundamental state policy, by the universal concern of society and attention.
While rural science and technology agricultural fast development, accelerate the paces of China's new countryside construction planning, will take leave of in the near future the epoch " lived scattered " in each family, same village, instead will be the general layout lived in concentrated communities of life, medical treatment, science, the complete same village of culture " soft or hard " facility condition.Rural area live in concentrated communities life can not only accelerate infrastructure, education universal, the living standard in rural area can also be greatly enhanced, but the ecological environment of surrounding will be brought the biggest challenge by the high-density aggregation pattern of population, wherein polluting the most prominent is exactly that people live produced sanitary sewage, and this seriously hampers the paces of new rural village development construction.
Sanitary sewage is mainly made up of feces and wash water, containing substantial amounts of Organic substance, such as cellulose, starch, saccharide and fat protein etc., under anaerobic bacteria effect, easily gives birth to odorant;The most often contain pathogen, virus and parasitic ovum;If sanitary sewage is not dealt carefully with, Water table polluted underground water will be entered by rainwash and diafiltration.But containing the more Organic substance being difficult to decompose in sewage, if these Organic substances are discharged in irrigation canals and ditches, subsoil water will be caused to be contaminated, at present for these Organic substances of degrading, the method generally adding chemical agent filters Organic substance, cause the secondary pollution of environment after chemical agent discharge, do not promote the use of.

Detailed description of the invention
Being further described this utility model below in conjunction with the accompanying drawings, protection domain of the present utility model is not limited to the following stated:
nullAs shown in Figure 1,A kind of biological sewage with bio-carrier structure processes master station,It includes the grid canal 1 the most sequentially connected、Acidifying regulating reservoir 2、Preliminary filter 3、Anaerobic biofilter 4、Oxygenation pond 5、Aerobic biofilter 6、Whole filter tank 7、Plnat monitoring pond 8 and canal 9 of releasing,It is added with anaerobic fermentation bacterium in described acidifying regulating reservoir 2,Bio-carrier structure is may be contained within anaerobic biofilter 4 and aerobic biofilter 6,Filling-material structure is by the boulder bed 10 being sequentially arranged from the bottom up、Rice rock layers 11 and fine sand layer 12 form,Anaerobic biofilter 4 is all added with Anaerobe carrier in rice rock layers 11 and fine sand layer 12,Aerobic biofilter 6 is all added with aerobe carrier in rice rock layers 11 and fine sand layer 12,Release and be provided with bilge discharge pipe 13 on the sidewall of canal 9,It is provided with band steel grizzly bar 14 in described grid canal 1,Floating thing and the float of larger particles in sanitary sewage can be intercepted by band steel grizzly bar 14.As it is shown in figure 1, be provided with aerator 15 in oxygenation pond 5, aerator 15 can be supplemental oxygen in sewage, its purpose is to provide the energy of decomposing organic matter to aerobe carrier.
The thickness of described rice rock layers 11 is equal with the thickness of fine sand layer 12;The thickness of described boulder bed 10 is more than the thickness of rice rock layers 11, and boulder bed 10 is for reducing the flow velocity of sewage.
As it is shown in figure 1, the step that this utility model processes sewage is as follows:
S1, the sewage that settlement is discharged through pipeline collect laggard enter in grid canal 1, floating thing and the float of larger particles in sanitary sewage are intercepted by band steel grizzly bar 14, in order to avoid its blocking subsequent technique facility, wherein the direction of arrow is the flow direction of sewage;
S2, grid canal 1 water outlet gravity flow enter in acidifying regulating reservoir 2, and the water quality and quantity of sanitary sewage is adjusted by acidifying regulating reservoir 2;
Sewage in S3, acidifying regulating reservoir 2 enters in preliminary filter 3, and preliminary filter 3 settles fine particle thing;
Sewage in S4, preliminary filter 3 enters in anaerobic biofilter 4, and the macromole persistent organic pollutants in sanitary sewage are generated the degradable organic pollution of little molecule by Anaerobe carrier open loop chain rupture;
Sewage in S5, anaerobic biofilter 4 enters in oxygenation pond 5, now starts aerator 15, aerator 15 supplemental oxygen in sewage, and the sewage being entrained with oxygen enters in aerobic biofilter 6;
Aerobe carrier in S6, aerobic biofilter 6 makes the little molecular organic pollutants decomposition and inversion in sanitary sewage become carbon dioxide and water, it is achieved thereby that there is the decomposition of hardly degraded organic substance in sewage;
Sewage in S7, aerobic biofilter 6 enters in whole filter tank 7, and whole filter tank 7 settles the aging biomembrane come off in aerobic biofilter 6, reaches to optimize the purpose of effluent quality;
Sewage in S8, whole filter tank 7 flows in plnat monitoring pond 8, by water plant the process effluent quality situation by the whole sanitary sewage disposal station of its healthy growth situation observation understanding of planting in plnat monitoring pond 8, after meeting emission request water outlet by the bilge discharge pipe 13 on canal 9 of releasing be emitted near waters, earth's surface, it is achieved thereby that the detection of sewage, more can actual response effluent quality situation, have the advantages that accuracy of detection is high.Hardly degraded organic substance in sewage can gradually be decomposed by this sewage disposal master station by Anaerobe carrier and aerobic bio-carrier, improves the decomposition efficiency of sewage, it is not necessary to utilize chemical agent filter tank, protect ecological environment.
