Principle of work of the present utility model is:
Waste water is after pre-treatment, fluidized-bed reaction room is entered by water inlet pipe bottom one-level anaerobic reactor, COD biochemical degradation is carried out with the anaerobic grain sludge Homogeneous phase mixing of the inside, COD volumetric loading is herein very high, major part influent COD is degraded herein, produce a large amount of biogas, the biogas produced is collected by one-level triphase separator, because the work of expansion done liquid in biogas Bubble Formation Process creates the effect of air lift, make biogas, the mixture of mud and water rises to the cyclone gas-liquid separator of reactor head along upcast, biogas is at this place and mud-water separation and collect from entering bimodulus gas holder the communicating pipe at cyclone gas-liquid separator top, be stored in gas holder inner membrance.According to the pressure in gas holder, suitably pressure can be regulated with reducing valve.Combustion chamber is transported to finally by methane outlet pipe.
Muddy water mixed solution then turns back to the bottom of fluidized-bed reaction room along downtake, fully mixing, realizing the internal recycle of mixed solution with granule sludge with intaking.Difference according to different inlet COD loadings and reactor constructs, and internal recycle flow can reach 5 ~ 20 times of flooding velocity; Granule sludge in reaction chamber reaches fluidisation completely, has very high rate of mass transfer, makes the first reaction chamber have very large organics removal ability.Waste water after the process of fluidized-bed reaction room is except a part participates in internal recycle, all the other waste water is by after one-level triphase separator, and penetration depth purification room is carried out rest COD degraded and produced process of methane, is precision processing district herein, waste water is better purified, improves effluent quality; Because most COD is degraded, so COD load is lower, gas production rate is also less, and the biogas that this place produces is collected by secondary triphase separator, enter cyclone gas-liquid separator by effuser, and discharge collection from the methane outlet pipe at cyclone gas-liquid separator top; Waste water after the process of precision processing district is after the effect of secondary triphase separator, and supernatant liquor is drained through rising pipe, and granule sludge then returns precision processing district Sludge Bed.
Compared with prior art, the beneficial effects of the utility model are:
1. the utility model adopts anaerobic treatment reactor and the integrated design of collecting methane storing device, and bimodulus gas holder is arranged on the top of anaerobic reactor cylindrical shell.Both save occupation of land like this, effectively can collect again the biogas that COD process produces, without foul smell, collecting methane rate is high simultaneously.
2. bimodulus gas holder adopts dual-mode design, and gas holder inner membrance is elastica, can move up and down, and maintains constant pressure; Gas holder adventitia plays double protection, also constant for control pressure.
3. bimodulus gas holder material of the present utility model is PVDF rotproofing, durable in use.
4. the utility model not only has the advantage of traditional anaerobic reactor, only adopt an anaerobic reactor cylindrical shell, but its processing volume rate of load condensate is equally very high simultaneously.Internal recycle effect of the present utility model, fluidized-bed reaction room is made not only to have very high biomass, mud is long for age, up-flow speed is fast, the granule sludge of these indoor is made to reach expansion, fluidized state completely, there is very high rate of mass transfer, muddy water is fully mixed, thus greatly increase biochemical reaction rate and organics removal ability.
5. anti-impact is by force load.Two-stage triphase separator of the present utility model makes biomass be effectively detained.Primary separator (bottom) is separated natural pond G&W, second-stage separator (top) separating particles mud and water, because most of biogas is separated in primary separator, there is turbulent fluctuation hardly in deep purifying reaction chamber, therefore second-stage separator can not by the impact of high gas flow rate, effectively can be separated the granule sludge in water outlet, outlet effect is good.
