Method for treating agricultural ecological waste by using polymeric membrane

Abstract

The invention relates to a method for treating agricultural ecological waste by using a polymeric membrane. The method comprises the following steps: mixing livestock and poultry manure with a water content of 60-80% and agricultural waste with a water content of 20-40% according to a mass ratio of (5-10): 1 to form a fermentation raw material; stacking the fermentation raw material into a fermentation pile body; coating the top surface and the periphery of the fermentation pile body with a selective permeable membrane; and inputting oxygen-containing gas into the fermentation pile body so as to subject the fermentation pile body to aerobic fermentation. When oxygen-containing gas is blown into the fermentation pile body, a micro-high-pressure cavity is formed in the selective semi-permeable membrane, and the micro-high-pressure cavity can provide a suitable fermentation environment for aerobic microorganisms in the fermentation pile body, so organic substances in the livestock and poultry manure can be fully degraded, and absorption and utilization of the livestock and poultry manure by crops are facilitated; and meanwhile, water vapor and carbon dioxide can be diffused out by virtue of a microporous structure of the selective semi-permeable membrane, so air flow balance inside and outside the fermentation pile body is maintained, oxygen easily flows into the fermentation pile body, and organic substances in the livestock and poultry manure can be further fully degraded.

Description

technical field [0001] The invention relates to the technical field of livestock and poultry manure treatment, in particular to a method for treating agricultural ecological waste with a polymer membrane. Background technique [0002] Livestock breeding and agricultural planting are important parts of agriculture and animal husbandry, and the two are closely related. The planting industry can provide feed for the breeding industry, and the breeding industry can provide sufficient fertilizer for the planting industry. The organic combination of the two achieves the purpose of improving the rural ecological environment and promoting the development of ecological agriculture, and enables the resource utilization of livestock and poultry manure that originally polluted the environment. It not only solves the increasingly serious environmental pollution problem in rural areas, but also enables sustainable development of ecological agriculture and drives regional economic develop...
