| The village Biogas construction is conducive to constructing the socialism new village, raising the living standards of people, improving village productivity, excellenting village energy struction and protecting the village ecosystem environment. The processing parameters impact biogas production rate and quality seriously.it is high efficiency to produce biogas that choice appropriate processing parameters. Moreover, Biogas Residual Products are a kind of superior organic fertilizers, they could improving soil eco-system and struction, soil fatty dint, effectively regulating the water, fatty, spirit, hot in the soil, promoting the environment virtuous cycle of the soil ecosystem.The experimental simulated the principle of operation of hydraulic pressure methane tank, proceeded from effective demand, through the medium of self-command methane fermentation plant, we looked into know clearly that these three factors including ratio of muck and grass, the ratio of materials, inoculum impacted to biogas production. In addition, through Orthogonal Cross, we got know clearly stack retting processing mode, ratio of muck and grass, the ratio of materials and inoculum.Through four different ratio of muck and grass, we looked into the effect of lowering of charge interval on aerogenesis. The results showed that under 8% of raw total solids concentration, 6.8～7.4 of pH, the methane tank sludge, 20% of them inoculated, after 30 days of fermentation, it was pure pig muck that the effect was execellent. The total aerogenesis tolerance was 88851.84 mL, the day aerogenesis tolerance was 2961.73 mL, the pit held aerogenesis rate was 0.4527 m3/m3·d , the stuff held aerogenesis rate was 0.5328 m3/m3·d, the raw material aerogenesis rate was 0.1999 m3/kg·TS. All of them were raised 41.61%, 41.61%, 41.56%, 41.63% and 41.67% in comparison.on carbon-nitrogen ratio definite occasions, through three different ratio of muck and grass, we looked into the effect of lowering of charge interval on aerogenesis. The results showed that under 8% of raw total solids concentration, 6.8～7.4 of pH, the methane tank sludge, 20% of them inoculated, after 30 days of fermentation, it was carbon-nitrogen ratio for 2:1 that the effect was execellent. The total aerogenesis tolerance was 56662.28 mL, the day aerogenesis tolerance was 1888.74 mL, the pit held aerogenesis rate was 0.2888m3/m3·d , the stuff held aerogenesis rate was 0.3398 m3/m3·d, the raw material aerogenesis rate was 0.1274m3/kg·TS. All of them were raised 30.29%, 30.29%, 30.27%, 30.29% and 30.27% in carbon-nitrogen ratio for 3:1.Though different inoculum of the methane tank sludge, we studied that the inoculum effected on the biogas production. The condition was the same to the former, but the inoculum were 10%, 20% and 30% separately. The result showed that 30% of inoculum was execellent, with 37873.60 mL of the total aerogenesis tolerance, 1262.45 mL of the day aerogenesis tolerance, 0.1930 m3/m3·d of the pit held aerogenesis rate, 0.2271 m3/m3·d of stuff held aerogenesis rate, 0.0852m3/ kg·TS of the raw material aerogenesis rate. These results indicated that the total aerogenesis tolerance were raised 44.815% and 174.49% in comparison to 20% and 10% separately, 44.81% and 174.49% at pit held aerogenesis rate in comparison to 20% and 10% separately, 44.79% and 174.54% at the stuff held aerogenesis rate in comparison to 20% and 10% separately , 44.90% and 174.84% at the raw material aerogenesis rate in comparison to 20% and 10% separately.different stack retting processing mode also impacting biogas fermentative efficency. The experimentation condition was the same to the former, but materials were putted in practice respectively to three processing modes including the outside stack tetting, pool inside stack retting and not stack retting. The result showed that pool inside stack retting was execellent, The total aerogenesis tolerance was 56662.28 mL, the day aerogenesis tolerance was 1888.74 mL, the pit held aerogenesis rate was 0.2888m3/m3·d , the stuff held aerogenesis rate was 0.3398 m3/m3·d, the raw material aerogenesis rate was 0.1274m3/kg·TS. All of them were raised 31.63%,31.63%,31.11%,31.11% and 31.20% in no stack retting.L9 (34) Orthogonal Cross was used in the study for the best control condition of biogas fermentation, the factors concluded stack retting processing mode, ratio of muck and grass, the ratio of materials and inoculum. Every factor had three levels, stack retting processing mode concluded stack retting in the pool, out of the pool and no stack retting, ratio of muck and grass concluded 2:1, 2.5:1 and 3:1, the ratio of materials concluded pig muck+straw, pig muck+green grass and pig muck+com , inoculum concluded 10%,20% and 30%.Other condition was the same as the former. From the study, we can know that the four factors' effect was the ratio of materials > ratio of muck and grass > inoculum > stack retting processing mode. The best condition theoretical was no stack retting, 30% of inoculum, 3:1 of ratio of muck and grass, pig muck+green grass. The best condition in the study was stack retting inside, 30% of inoculum, 9 days of period of employing materials, the methane tank sludge. we can choice one of them according to the reality condition. Furthermore, the experiment sampling 11 the swatch of Biogas fermentation raffinate and Biogas fermentation leabvings in Sha Ping Ba, He Chuan, Fu Ling erea. We found that the inclusions were not only abundant organic matter, but also many microelements such as nitrogen, phosphor, Potassium, natrium, calcium, cuprum, iron, magnesium, Manganese and zincum. These were importance to promoting plant growth and advancing agricultural production quality.Finally, some further researches were suggested on the following derections such as stack retting time ; multi-evaluation to biogas fermentation relict.
