Water solenoid valve 45, go out water solenoid valve 46, restart normal filtration.
Being illustrated in figure 2 process chart of the present utility model, sewage is laggard through one-level pretreatment and front end anaerobic treatment
Entering this utility model system, original biochemical process part has been carried out proposing mark transformation by this utility model, has increased activated carbon filtration newly
Part, pretreated sewage reaches after sequentially passing through density biochemical part of the present utility model and the process of activated carbon filtration fraction
Mark discharge.
Concrete technology flow process contains following steps:
Step one: added to molten medicine-chest 14 by special dietary thing, flow to two explosive boxs and stores stand-by after having dissolved.
When needing to add special dietary thing in biochemistry pool, it is added in anoxic pond 11, Aerobic Pond 21 by two dosing pumps respectively.
Step 2: use the sewage that need to process to tame and docile in denitrifying bacterium tames reactor 110, nitrifier domestication reactor 28
Change and cultivate denitrification, nitrification strain, when requiring supplementation with interpolation strain, open denitrifying bacterium dosing electromagnetic valve 111, nitrifier dosing
Electromagnetic valve 29, supplements and adds to anoxic pond 11, Aerobic Pond 21.
Step 3: the sewage after preprocessed and front end anaerobic treatment sequentially flows automatically entrance anoxic pond 11, Aerobic Pond 21, good
The root nodule bacteria (Rhizobium sp.) that preserving number is CGMCC NO.10721, Aerobic Pond is added in oxygen pond, anoxic pond and Aerobic Pond
Reflux pump 25 is set in 21, by the mixed-liquor return after aerobic to anoxic pond, it is achieved nitrification-denitrification denitrification reaction；
Step 4: the elevator pump 32 that sewage is arranged in intermediate pool 31, enters in active carbon filter 41, lives
Property charcoal adsorption filtration, adsorb residual organic matter pollutant, subsequently via rubber filter cloth parcel perforation outlet pipe water outlet, go scrubbing
Suspended particulate contaminants matter in water；
Step 5: monitor filter 41 Inlet and outlet water pressure differential according to water-in and water-out Pressure gauge, when pressure reduction is big, automatically turns on anti-
Rinse-system, uses air and clear water that filter 41 is carried out backwash, to keeping running normally and efficiently.
The foregoing is only the case that is embodied as of this utility model patent, but the technical characteristic of this utility model patent is also
Being not limited to this, any those skilled in the relevant art are in field of the present utility model, and change or the modification made all are contained
Among the scope of the claims of the present utility model.
