Problems solved by technology

[0003] However, the traditional composting process takes a long time and has low efficiency, making it difficult to meet the needs of the development of large-scale aquaculture. Moreover, during the composting process, malodorous gases, such as ammonia and hydrogen sulfide, are often produced, which have a negative impact on the air environment.
And due to the volatilization of ammonia, the loss of nitrogen nutrients in the compost, which reduces the agricultural value of compost products, directly affects the survival and development of compost products in the market

Embodiment

[0011] The composting period is 20 days, and the composting raw materials are livestock and poultry farming waste (chicken manure, duck manure, pig manure), rice straw and sawdust. % and 86.34%. First, mix the compost raw materials with a total weight of 100kg evenly, adjust the initial moisture content to 66%, and the carbon / nitrogen ratio to 25%, spray bamboo acetic acid 11 with a dilution ratio of 1:1500, and perform forced ventilation static aerobic composting, composting During the process, the highest temperature is controlled below 65°C. After composting for 5 to 7 days, 1L of bamboo acetic acid with a dilution ratio of 1:1500 is sprayed on the surface of the raw materials. After composting, the moisture content of raw materials is 49.5-54.2%, the content of organic matter is 54.24-67.59, and the temperature of the compost is 42°C. After one month of composting, it can be applied to the farmland as organic fertilizer. The nitrogen loss rate in the raw materials after c...

Abstract

The invention discloses a high effective composting method of domestic breeding waste through bamboo acetic acid, which comprises the following steps: controlling initial moisture percentage of composting material at 62-68%; setting the rate of carbon and nitrogen at 25%; reinforcing to ventilate to do aerobic compost below 65 deg.c for 5-7d; adopting domestic waste, straw, sawdust as raw material; allocating 100g compost and 2L bamboo acetic acid with diluting rate at 1:500-1:2000.

Description

technical field [0001] The invention relates to the field of treatment and recovery of livestock and poultry breeding waste, in particular to a method for efficiently composting livestock and poultry breeding waste by using bamboo acetic acid. Background technique [0002] The composting process has been widely used in the treatment of livestock and poultry farming waste because of its high degree of resource utilization and low environmental hazards after treatment. [0003] However, the traditional composting process takes a long time and has low efficiency, which is difficult to meet the needs of the development of large-scale aquaculture. Moreover, during the composting process, malodorous gases, such as ammonia and hydrogen sulfide, are often produced, which have a negative impact on the air environment. And due to the volatilization of ammonia, the loss of nitrogen nutrients in the compost is caused, the agricultural value of the compost product is reduced, and the sur...
