Abstract

The invention discloses a harmless processing method of sesame duck farm wastes. The processing method comprises steps: waste collecting, duck feather processing, duck manure and urine processing, duck corpse processing, earthworm culturing, and reasonable utilizing. The pollution caused by a large amount of duck feathers, duck manure, duck urine, and corpses of irregularly dead ducks in a large sesame duck farm is eliminated by the provided method; at the same time, the wastes are fully utilized; the environment is protected; the virtuous cycle is created; moreover, the cost is low, and the method is safe and reliable. The wastes are processed, at the same time, great benefits are generated for the farmers; farmers are pleasure to process the wastes; the wastes are biologically fermentedand decomposed by earthworms, the processing is timely and efficient, secondary pollution is avoided, ecological circle is formed, no pollution or residue is generated, and the method is feasible andenvironmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of waste treatment, and in particular relates to a harmless treatment method for waste in sesame duck farms. Background technique [0002] With the rapid development of my country's animal husbandry and breeding industry, the scale of the current breeding enterprises is also rapidly moving towards the direction of intensification and scale. At the same time, this large-scale breeding has exposed a variety of very serious problems. The most serious of these problems is environmental pollution, which has aroused widespread public concern. For example, some large-scale duck breeding enterprises produce more and more wastes such as feces due to the large scale of breeding. However, the commonly used treatment technologies for wastes such as duck feces, duck carcasses, and duck feathers produced every day have their own problems. There are various problems such as high processing costs, and the processing capacit...
