TECHNOLOGY FOCUS - ENVIRONMENT - Preferred Method: The method further comprises collecting the waste; spreading a layer of plant padding in the fermenting section; and introducing the collected waste into the fermenting section. It comprises collecting the waste into the waste collecting pond; precipitating; introducing into a transit pond and a hardening and tempering pond; adding dry waste block collected from the culturing shed; stirring; introducing into a fermenting section after uniformly stirring; and further adding the precipitate generated while preprocessing the precipitate, into the fermenting section. The method comprises introducing the waste into a culturing shed waste pond; after periodically introducing the waste into the waste collecting pond, introducing into the hardening and tempering pond; stirring; introducing into the fermenting section after uniformly stirring; further periodically adding the precipitate generated while preprocessing the precipitate and the waste generated while sinking waste with water; and introducing into fermentation section after adjusting in the hardening and tempering pond according to the condition of the precipitate. After solid liquid separation of wastewater, the liquid is introduced into a methane pond to extract methane, which is introduced into the hardening and tempering pond, the solid waste is directly added into the hardening and tempering pond and delivered into the fermenting section after uniformly stirring, and methane residue is periodically processed in the methane pond into the fermenting section. The padding comprises 30-60% rice hull and 40-70% sawdust. The padding in the fermenting section is as high as 1.0-2.0 m. The sprayed waste can be sunken not deeper than 30-60 cm. The humidity of the padding, which is 30-60 cm below the surface, is maintained at 40-65%, to maintain normal fermentation. The beneficial microorganism comprises not less than 0.1-0.3 kg/m3 of Bacillus subtilis, Saccharomycetes, and Lactobacillus. Preferred Device: The side part of the waste collecting pond is provided with a wastewater ditch, which passes through and communicates with the transit pond. The wastewater ditch is inlaid with a valve. One side of the waste collecting pond adjacent to the wastewater ditch is provided with a wastewater inlet. The dynamoelectric stirring blade is a dynamoelectric stirring blade eccentrically installed in the hardening and tempering pond. The waste delivering pipe is provided with multiple downward output ends arranged at intervals.
