Problems solved by technology

Few of these crop straws can be used for silage, and most of them are used as fuel and fertilizer. Even if they are used as a small part of the feed, the traditional direct feeding method is mostly used, and the digestion and utilization rate is very low.

Embodiment 1

[0022] A. Crushing and mixing

[0023] About 10 tons of perishable garbage per car is crushed within 3 hours until it can pass through a 1.2cm×1.2cm sieve, and then enters the aerobic fermentation bin, and adds EM from Guangzhou Yibang Biotechnology Co., Ltd. to the aerobic fermentation bin - For type 1 strains, mix well, adjust the carbon-nitrogen ratio of perishable waste to 25:1, and the moisture content to 50% by weight;

[0024] B. In piles

[0025] Take the mixed perishable garbage per two cars obtained in step A as a pile unit, and evenly distribute 4 forced ventilation pipes in the pile. The height of the pile is less than 2 meters, the bottom width is less than 5 meters, and the surface of the pile Cover with 10cm semi-clinker, the ventilation pipe is connected with the ventilation equipment, and a thermometer is installed in the pile;

[0026] C. The first maturity stage

[0027] The perishable garbage after step B is piled up is the first maturity period within 1...

Embodiment 2

[0037] The same as in Example 1, except that the perishable garbage in the step A is crushed for 5 hours, the carbon-nitrogen ratio is adjusted to 35:1, and the moisture content is 70% by weight; in the step B, 8 forced ventilation pipes are evenly distributed in the pile body, and the pile body The debugging is 1.5 meters, the bottom width is 4 meters, and the surface of the pile is covered with a 20cm sieve; the first decomposing period of step C is 15 days, and when the temperature of the pile reaches 65 degrees, it is extended to 40 minutes, and the moisture content of the pile is controlled to 60% Percentage by weight; step D turned over for the first time when heaped for 14 days, and adjusted the moisture content to 70% by weight; 20 days after the first turning of step E was the second maturity period, turning once every 3 days, and water replenishment control in the first 10 days The moisture content is 60%.

Embodiment 3

[0039] The same as in Example 1, except that the perishable garbage in the step A is crushed for 4 hours, the carbon-nitrogen ratio is adjusted to 30:1, and the water content is 60% by weight; in the step B, 6 forced ventilation pipes are evenly distributed in the pile body, and the pile body The debugging is 1 meter, the bottom width is 3 meters, and the surface of the pile is covered with a 15cm sieve; the first decomposing period of step C is 13 days, and the temperature of the pile is extended to 50 minutes when the temperature of the pile reaches 75 degrees, and the moisture content of the pile is controlled to 70%. Percentage by weight; D step turns the pile for the first time when it is piled up for 15 days, and adjusts the moisture content to 60% by weight; 17 days after the first turn of the E step is the second maturity period, turns once every 2 days, and controls water replenishment in the first 10 days The moisture content is 55%.

Abstract

The invention aims to provide an aerobic composting method for organic perishable garbage. The method comprises the following steps: adding effective microorganism (EM) strains; crushing and mixing uniformly; forming a pile; entering a first composting period; turning the pile; entering a second composting period; sieving; and entering a later composting period so as to obtain the initial fertilizer. According to the method, the perishable garbage is utilized completely, and the perishable garbage is decomposed into the initial fertilizer according with the national standard by simple methods of composting, turning the materials and the like. Due to proper ventilation, pile-turning time and two-stage composting period, no odor and flies exist in the composting process, and the popularization and the application are more convenient.

Description

technical field [0001] The invention relates to a method for treating organic waste, in particular to an aerobic composting method for organic perishable waste. Background technique [0002] Three major problems facing the modern world: food problems, environmental problems and energy problems. It can be said that the solutions to these three major problems are all related to microorganisms. As far as feed is concerned, with the development of animal husbandry production, the protein feed necessary to ensure livestock is increasingly scarce. It is necessary to solve the serious shortage of feed protein in my country and actively use it. It is an important way to use renewable resources to produce feed protein from waste materials from various agricultural and sideline products processing. According to relevant estimates, there are about 100 billion tons of cellulose resources in the world every year, and about 5 billion tons in my country, of which crop straw (table straw, r...
