Research Of The Surplus Sludge By Underground River Anaerobic Fermentation

This paper mainly studied the surplus sludge to tire of in the oxygen reactor in the underground river to carry on tires of the feasibility and the best craft parameter which the oxygen fermented.Tired of in the oxygen fermentative process through the analysis these influence factors to provide the rationale for the methane large and middle scale projects practice, and the underground river surplus sludge reactor experiment also piled up the question for the city dirtwater works surplus sludge to provide a new key to the situation.Throught the experiment in 36℃and pH at the range of 6.7-7.25 we can find the best conditions of fermentation disgust Custody is: moisture of activated Sludge is 80%,C/N is 20, inoculum is 20%, activated Sludge/breed aquatics dejection/MSW is 60%:30%:10%.This paper raised that we can combine sewage Plant with underground river throught the experiment,biogas could be used in life or in sewage Plant to make it work better. Biogas liquid residue could be wildly used in agriculture for its rich content of nutriment. We can reduce the waste and control pollution at the same time.This technology fluidizes biomass materials and make the entrance of materials and release of residue are liquid form with automation,manage and low cost. The fluidized biomass material has small dimension and using efficiency of marsh gas reactor improves geminationly, it can produce marsh gas quickly and increased output. Reactor what likes a obdurated underground river is used for country marsh gas family pool with several stere and also for natural gas mine with several million stere. marsh gas has 75% methane. Get rid of CO2, H2O and H2S and so on,there will be 95% methane. Then, the quality is better than natural gas.
