Abstract: A methane fermentation method having the steps of finely pulverizing an organic substance adjusted such that a moisture content of the organic substance is equal to or less than 10%, in a wet bead mill; supplying the organic substance which is finely pulverized in the pulverization step to a methane fermentation chamber and decomposing the organic substance with an anaerobic microorganism to cause methane fermentation so as to generate methane gas; separating, with a UF membrane, a digestive fluid after the methane fermentation in the methane fermentation step into a concentrated liquid and a permeation liquid; returning the concentrated liquid separated in the separation step to the methane fermentation chamber; and agitating the contents of the methane fermentation chamber with a water flow produced by the return of the concentrated liquid in the return step.

Abstract: A novel carbon absorption material is described which is formed from anaerobic digestate. The material has a hollow tubular structure and is particularly advantageous in converting hydrogen sulfide in biogas and in absorbing the converted sulfur and sulfur compounds from biogas into its structure. The material after use as a hydrogen sulfide absorbent has value as a horticultural or agricultural product or as a sulfur impregnated activated carbon. The process for producing this novel carbon absorption material is described. In an embodiment, the process described uses in particular, a humidified inert gas over a temperature range of between about 500° C. to 900° C. to convert anaerobic digestate to an active carbon absorbent. The thermal treatment is relatively mild and retains the fibrous structure of the source material while removing cellulosic and hemicellulosic components from the anaerobic digestate.

Abstract: A digester system for digesting feed material comprises a digester tank, a thickener, and a seal system. The digester tank generates a first digested material and biogas from the feed material. The thickener is operatively connected to the digester tank to remove a second digested material from the feed material to alter a solid content of the feed material in the digester tank. The seal system substantially prevents the thickener from removing biogas from the feed material with the second digested material.

Abstract: A method for reducing release of resistance genes during sludge anaerobic treatment includes controlling concentration of to-be-treated sludge in a concentration tank to be 12-20 g/L by sedimentation under gravity. The concentrated sludge is transferred to a supersonic pre-treatment device to proceed with supersonic pre-treatment. The supersonic pre-treatment is conducted for 5-30 minutes at a power of 0.1-0.5 kW and a frequency of 10-40 kHz. The pre-treated sludge is then transferred to an anaerobic treatment device for anaerobic treatment. The anaerobic treatment is conducted for 4-12 days at a temperature of 20-37° C. The release amount of resistance genes in the residual sludge and the supernatant liquid in the anaerobic treatment device is detected. A feedback dosage of an alkali liquid is fed into the anaerobic treatment device according to the release amount of the resistance genes, controlling a pH value to be 9.0-11.0 during the anaerobic treatment.
