Fast composting technique suitable for cold area and preparation method of microbial inoculant

Abstract

Provided are a fast composting technique suitable for a cold area and a preparation method of a microbial inoculant. The method comprises the steps of (1) preparing heavy metal passivating agent in compost, (2) preparing compost compound microorganism inoculant, (3) preparing compost material, (4) preparing air-breather, (5) placing the compost material on the air-breather, centered around the straw bundle, placing the compost material in long strip bundles with 1.5 meters height, 8-10 meters length and 2.5-3 meters of width, making the sections into trapezoidal or semi-oval shape, using air blower to ventilate the straw bundle, controlling the ventilatory capacity at 2-4 cubic meters/hour in the beginning of the heating stage of the compost material, controlling the ventilatory capacity at 0.5-1.5 cubic meters/hour in the fermenting stage, and at last finishing the livestock manure high temperature aerobic composting process. The method can be applied in the fields of resource utilization of waste materials and organic fertilizer production.

Description

[0001] Technical field: [0002] The invention relates to a rapid composting technology suitable for cold regions and a preparation method of a rot-promoting bacterial agent. [0003] Background technique: [0004] With the development of the livestock and poultry breeding industry from decentralized management to large-scale and intensive models, breeding communities and thousand-head pastures continue to emerge. While providing people with meat, milk, eggs and other living materials, the environmental problems they bring are also increasing. Seriously, due to the limited land for waste disposal around the farms and the lack of efficient harmless treatment and resource utilization technologies, a large amount of livestock and poultry manure and other pollutants are randomly piled up or directly discharged into the environment, seriously affecting The production and life of the people around the farm have been greatly improved. Composting treatment is the most effective way to...
