The invention has the beneficial effects as follows:
(1), by integrated burying in underground such as grating tank, equalizing tank, hydrolytic tank, one-level biochemistry pool, secondary biochemical pond, settling tank, clear water sterilization pool, sludge sumps, solve the large problem of floor space.
(2) in hydrolytic tank, hang with spandex fiber compounded mix to increase microbial biomass, in pond, there is mud mixed liquid and the microbial film of high density, in pond, the organism oxygen bacterium of being held concurrently is degraded, improve the biodegradability of waste water, simultaneously, under the effect of microorganism, organonitrogen and ammonia-state nitrogen are converted into N2 and NxO gas.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As shown in Figure 1, comprehensive wastewater goes macrobead suspended substance to flow into wastewater equalization pond from the grid lattice of flowing through; After waste water homogeneous is all measured in equalizing tank, squeeze into hydrolytic tank by liquidometer control by sewage pump, utilize anaerobion to degrade to pollutents such as N, P, CODcr, BOD5 in waste water.In hydrolytic tank, hang with spandex fiber compounded mix to increase microbial biomass, in pond, there is mud mixed liquid and the microbial film of high density, in pond, the organism oxygen bacterium of being held concurrently is degraded, improve the biodegradability of waste water, simultaneously, under the effect of microorganism, organonitrogen and ammonia-state nitrogen are converted into N2 and NxO gas.Hydrolytic tank water outlet flows into one-level biochemistry pool and secondary biochemical pond, under aerobic microbial process, NH4+ in waste water is converted into NO2-and NO3-.Again by the oxidative metabolism effect of the aerobic microbiological adhering in elastic filler in pond, the organic pollutant in Decomposition Wastewater, thereby reduce its BOD5, CODcr, etc. pollutent index.One-level biochemistry pool and the water outlet of secondary biochemical pond are from flowing into settling tank, and the mud of precipitation is suitably squeezed into sludge sump digestion process through air lift, and the sewage of settling tank mainly carries out flowing into follow-up clear water sterilization pool qualified discharge after mud-water separation again.After the excess sludge digestion of sludge sump accumulation, transported outward by slush pump periodic cleaning, denitrification denitrogenation processing is carried out in supernatant liquor back hydrolysis pond.
Wherein, hydrolysis acidification pool adopts buried steel construction.This pond is the aerobic-anaerobic microbe that utilizes occurring in nature, and they are more in occurring in nature quantity, and reproduction speed is very fast.It can large molecular weight can biochemical organic substance decomposing be small organic molecule, as polysaccharose substance is decomposed into monose or organic acid, protein is decomposed into amino acid, lipoid material is decomposed into lipid acid and glycerine.To be difficult to biodegradable organic matter degradation for can biochemical organism, improve the bio-degradable of waste water, alleviate the organic loading of follow-up aerobic section.Major equipment is the elastic filler of maintaining facultative biological bacteria.The premiere feature of hydrolytic tank is denitrogenation; Next is that mud discharges phosphorus.Nitrifier by appendix on filler becomes nitrate mineralized nitrogen.Nitrated is the process of two steps, has utilized respectively two quasi-microorganisms, i.e. nitrite bacteria and nitrate bacterium.The first step changes into nitrite ammonia nitrogen, and first ammonia nitrogen changes into nitrite by nitrite bacteria.Nitrite bacteria has the unicellular Pseudomonas of nitrous acid, nitrous acid Helicobacterium and nitrous acid Coccus.Be that nitrate is completed by nitric acid acid bacterium Nitrite transformation, Nitromonas is also made up of Bacillaceae, spirillum and Coccus.Nitrite bacteria and Nitromonas are referred to as nitrifier.Nitrifier is the autotrophy Gram-negative aerobic bacteria of obligate, and they utilize the energy discharging in mineralized nitrogen process as self the metabolic energy.
Although the present invention discloses as above with preferred embodiment, so it is not in order to limit the present invention.Persond having ordinary knowledge in the technical field of the present invention, without departing from the spirit and scope of the present invention, when being used for a variety of modifications and variations.Therefore, protection scope of the present invention is when being as the criterion depending on claims person of defining.
