The environmental pollution caused by environmental pollution has increased day by day, and the government has been taking extreme measures due to environmental pollution such as marine dumping and discontinuation of marine dumping.

Therefore, livestock manure and waste through long-term, repetitive experiments in a separate pilot facility to solve the above problems and improve the conventional patented process. In the waste treatment method, it greatly reduces initial capital investment and facility maintenance cost, handles a large amount by low cost, produces high-quality organic fertilizers generated in the processing process, and distributes them to farms, raising livestock manure without environmental pollution, It relates to a method and apparatus having the purpose of treating waste, feces.

Solids containing organic matter. Liquid organics and livestock manure. There are many methods for producing high-quality organic fertilizers by discharging wastes into rivers or producing zero-quality organic fertilizers without discharge. Promoting acidification of soil due to lack of proper use of chemicals, pollution of rivers and streams during discharge, desolation and red tide of coastal shores during ocean dumping, evasion of livestock farms by expensive waste treatment, and lack of organic fertilizer In the facility investment, there are many problems such as an increase in the initial investment cost due to unnecessary duplication of equipment and an increase in the number of facilities, and the maintenance cost of the facility is constantly being developed to solve the problem.

Conventional techniques for the treatment of solid, liquid organics and livestock manure wastes include fertilizers by mixing other subsidiary materials with the solids of manure and discharging liquid excrements that are not solids. In the non-discharge system, there are many conventional techniques, such as fermentation of liquid, solid organic matter, livestock manure, and waste by mixing other subsidiary materials, but the above problems have always been raised.

The present invention relates to a system for producing fertilizer by mixing and fermenting livestock manure, organic solids, liquids and wastes with other subsidiary materials as described above. It is technology that can

Problems that current zero discharge systems have to address;

1) Redundant parts of the facility can simplify functions, delete unnecessary processes,

2) stable supply and demand of chaff, sawdust and straw pellets

3) Problems in creating aerobic fermentation conditions to promote short-term first and second fermentation processes

4) Microbial sanction problem suitable for the promotion of the short-term 1.2 fermentation process

Although there are additional facilities to solve the above problems, there is no environmental pollution due to mass processing, no discharge and no odor, and the whole amount of animal waste and organic waste is produced in natural circulation type, that is, high quality organic fertilizer. Although the effect was much better than expected, it has not yet had a great effect on the reduction of initial investment cost and maintenance cost of facility.

The present invention relates to a method and apparatus for fertilizing livestock excrement and waste containing organic matter. The pilot equipment is operated for a long time and repeated for a long time to reduce facility investment and facility maintenance costs.
