Embodiment Construction

[0019] The present invention will be further described below in conjunction with embodiment.

[0020] A kind of method that promotes the fast decomposing and composting of potato starch processing waste residue, comprises the steps:

[0021] 1. Raw materials are dehydrated, and the pressing method is used to complete the overall dehydration of the potato starch processing waste residue, and the dehydration rate of the potato starch processing waste residue reaches more than 30%;

[0022] 2. Add an appropriate amount of biochar to the potato starch processing waste residue, adjust the carbon-nitrogen ratio, and increase the nutrient content of the potato starch processing waste residue;

[0023] 3. Add an appropriate amount of calcium additives to the potato starch processing waste residue. The calcium additive is calcium hydroxide or calcium carbonate to adjust the pH value of the fermentation broth, increase the enzyme activity of the fermentation broth, and promote the rapid...

Abstract

A method for promoting rapid composting of potato starch processing waste residues relates to the technical field of agriculture, and comprises the following steps: adding biomass charcoal, a calciumadditive and a complex microbial inoculant into a main raw material potato starch processing waste residues, turning and throwing the raw materials, uniformly mixing the raw materials, and rapidly composting the mixture. The invention provides a rapid and efficient development potato waste residue resource utilization technology. According to the technology, the carbon-nitrogen ratio is effectively adjusted and the enzymatic activity of fermentation liquor is improved; rapid composting of the potato waste residues is accelerated; and the effective utilization rate of the potato waste residuesis improved. The method has the advantages of simple operation, reduction of the caused resource waste and the pollution of the potato starch processing wastes to the environment, realization of the efficient, fast, environmentally-friendly, resource utilization and industrial promotion of the potato starch processing wastes, low resource utilization cost, easy operation, abundant nutrition of theprepared fertilizer, effective improvement of the soil structure, and facilitation of the crop planting.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a method for promoting rapid decomposing and composting of potato starch processing waste residue. Background technique [0002] The rise of the potato starch processing industry has strongly promoted the development of the potato industry, extended the industrial chain, and provided a new economic growth point for the development of agriculture and rural areas; however, the environmental pollution caused by the potato waste residue produced in the potato starch production process is also increasing. It has become a bottleneck problem that restricts the further development of processing enterprises. Potato waste residue is the main by-product in the potato starch production process, about 7 tons of waste residue is produced for every ton of refined starch produced; the main components of potato waste residue are water, cell debris and residual starch granules, and...
