Static-pile composting method for treating cow dung harmlessly

Abstract

The invention discloses a static-pile composting method for treating cow dung harmlessly. The method comprises the three steps that S1, a microbial inoculant is prepared, in specific, four kinds of microorganisms including ABTNL-2 bacillus subtilis, bacillus licheniformis, bacillus cereus and lactobacillus are utilized to prepare the microbial complex inoculant for cow dung composting; S2, cow dung composting is built, in specific, the microbial inoculant is inoculated to the mixture after the cow dung and plant materials are mixed, composting is built up after the materials are mixed evenly,a ventilation and temperature monitoring device is arranged in the compost, and the surrounding part of the pile body is completely covered with stack to preserve the heat; and S3, compost managementis conducted, in specific, air is injected into the pile body so as to ensure rapid warming and decomposition of the compost, the pile body temperature is monitored, the product after composting serves as biological organic fertilizer. The method can achieve rapid, simple and convenient harmless treatment of cow dung of small-scale farmers, and particularly can rapidly and completely inactivate the enterohemorrhagic escherichia coli O157:H7 in the cow dung, and the composting product can serve as the biological organic fertilizer to achieve resource utilization.

Description

technical field

[0001] The invention belongs to the technical field of agricultural biology, and in particular relates to a static composting method for harmlessly treating cow dung. Background technique

[0002] Beef is one of the main sources of meat in my country. With the improvement of people's living standards, the proportion of beef consumption has increased year by year, and the food safety problems that follow have become increasingly prominent. Beef is one of the main foods that cause enterohemorrhagic E. coli (enterohemorrhage E. Coli, EHEC) O157: H7 bacterial food poisoning. Eating beef contaminated with EHECO157:H7 can cause not only vomiting, diarrhea and other intestinal diseases, but also complications such as hemolytic uremic syndrome and encephalopathy, and even death. Therefore, it is called an emerging infectious disease together with AIDS and Ebola hemorrhagic fever, and is highly valued by the World Health Organization.
