Production equipment and preparation method of slow-release bio-organic fertilizer

Abstract

The invention relates to production equipment and a preparation method of a high-efficiency slow-release bio-organic fertilizer. The preparation of the bio-organic fertilizer is completed by utilizing the equipment. The preparation method of the high-efficiency slow-release bio-organic fertilizer comprises flows of crush, solid-liquid separation, high temperature aerobic fermentation, anaerobic fermentation, sterilization and disinfection, drying and granulation and the like. According to the invention, human and animal excreta, crop straws, commercial crop stem leaves, rotten vegetables and kitchen waste in daily life of people are really converted into a novel high-efficiency composite organic fertilizer matrix capable of slowly releasing mineral substances, the aims of resource recovery, reduction and circulation can be fulfilled, and the high-efficiency slow-release bio-organic fertilizer can be widely applied to various soils in various countries and regions all over the world and has obvious effects of improving the yield and quality of crops and reducing the environment problem caused by straw burning.

Description

technical field [0001] The invention relates to a fertilizer production equipment and a preparation method thereof, in particular to a slow-release bio-organic fertilizer production equipment and a preparation method thereof. Background technique [0002] Bio-organic fertilizer substrate is the direction of fertilizer development, and the space for future development is huge. During the "Twelfth Five-Year Plan" period, improving the agricultural ecological environment and improving the quality of agricultural products have become prominent issues in the sustainable development of agriculture in my country. The people's requirements for food quality are getting higher and higher, and the consumer demand for green food is growing at home and abroad. In recent years, my country's agricultural products have shown a low level of surplus. Producers are trying their best to find ways to improve the quality of agricultural products. Consumers are paying more and more attention to fo...

[0006] With the improvement of the quality of life, the kitchen waste of residents is increasing day by day. However, the main disposal method of kitchen waste in our country is to deal with domestic waste together. The disposal methods of domestic waste usually include incineration and landfill. If the municipal solid waste is incinerated Because the moisture content of food waste is often as high as 90%, and the calorific value is about 2100kJ / kg-3000kJ / kg, incineration together with other waste will not only fail to meet the heat generation requirements of waste incineration power generation (about 5000kJ / kg), On the contrary, it will cause the incinerator to burn insufficiently and produce dioxin and other substances; if domestic waste is landfilled, it will also be unsuitable for disposal due to the high moisture content of the mixed food waste

Moreover, incineration and landfill will not only lead to the waste of a large amount of organic matter, but also the landfill leachate will cause non-point source pollution, so it is necessary to treat food waste individually
