Problems and Countermeasures in Chicken Manure Drying
2018-05-23 17:01:00
There are five major defects in the ratio of dried chicken manure to organic manure: First, harmless treatment is not as good as organic manure. Dry chicken manure is basically not harmless. Chicken dung drying process, by a short time, a higher temperature will not completely kill some of the more stubborn harmful viruses, bacteria, pests and weed seeds. Scientific experiments have proved that livestock and poultry excrement need to be able to kill harmful viruses, germs, pests and weed seeds at a high temperature of 60-70°C for about 10 days. Organic manure is increased in temperature under the decomposition of biological bacteria and maintained at 60-70°C for more than 10 consecutive days. Therefore, the virus, pathogens, pests and weeds can be basically killed to achieve harmless standards.
Second, the protection of the environment is not as good as the organic fertilizer. During the transportation of chicken manure, the odor overflows. All the places passed are affected. During the drying process, the chicken odor emitted by the drying oven makes it difficult for the residents who live several kilometers away from the drying oven to suffer. This is even more serious under special weather conditions. As a result, many civil disputes and mass opinions were triggered. Now some provinces (cities) have explicitly banned the drying of chicken manure production. Organic fertilizer production, according to the requirements of environmental protection standards design production equipment and production processes. First of all, livestock and poultry manures are treated in a timely manner at the farm. The wastes are then processed and transported to the factory for secondary treatment and packaging. Therefore, it is a production process that cleans and purifies the environment.
Third, the intrinsic quality is not as good as the effect of organic fertilizer Dry chicken manure production by coal, electric energy heating to exclude chicken dung moisture. The higher temperature in the furnace during heating causes some loss of nutrients in the chicken manure, reducing the effectiveness of the fertilizer. In the organic fertilizer production process, the treatment of livestock and poultry manure is carried out under the action of the decomposition of biological bacteria. The temperature is gradually increased and maintained at a temperature of 60-70°C. The loss of nutrients in the livestock and poultry manure is not lost, but rather promotes the excrement. The conversion of molecular nutrients to small molecule nutrients and the development of more favorable crop growth materials, such organic fertilizers make plants more easily absorbed, and enhance the organic fertilizer's immediate effect.
Fourth, energy use is inferior to organic fertilizer science. Chicken manure is dried by coal and electricity. Each ton of dry chicken manure consumes 166 kg of coal and 32 kWh of electricity. Organic fertilizer production mainly depends on solar energy, bioenergy and a small amount of electricity. Each ton of powdered organic fertilizer produces less than 5 kWh of electricity. It helps to save non-renewable energy.
Fifth, it is not as good as the organic fertilizer production model. The use of agricultural waste is widely spread. The chicken manure drying furnace is mainly based on livestock and poultry manure, especially egg chicken manure. The organic fertilizer production model utilizes a variety of human, livestock, and poultry manure as the main raw materials. Can be more mixed, less mixed and not mixed with crop straw. It is better to produce organic fertilizers and add crop straws. The ratio of livestock manure to crop stalks is 3:1, and the organic content of fertilizer produced can reach more than 85%. Straw returning can maintain soil structure, increase soil fertility, facilitate agricultural production, reduce straw burning, and promote environmental sanitation.
Countermeasures for dealing with livestock and poultry manure Farmers need cheap, organic manure. How to come up with a set of organic fertilizer production equipment and technology that can produce cheap and plump to reduce production costs and reduce intermediate links?
The establishment of a centralized breeding area, the centralized management of livestock and poultry, the centralized epidemic prevention, and the centralized disposal of excrement are a modern intensive aquaculture model and a development direction. At present, the livestock and poultry excrement processing in the farms (districts) is slow. Many of the most important problems are the owners of the farms. They fear that the high prices of organic fertilizers produced cannot be sold, and that the investment in equipment is too large to receive investment. Special invited experts of the Hang Lung State Organic Fertilizer Technology Promotion Center, Mr. Wang Yan, a biochemist from Japan, and Mr. Zhuang Sen from Dr. Yoonji Machine Co., Ltd., after cooperation with the cooperation unit, solved this problem after several years of research and practice. The project has passed the acceptance test. And identification. The technology and equipment investment is small, one year to recover the investment, there are profits.
