Environmentally friendly waste disposal system

The present invention relates to a waste treatment system that treats livestock waste, food waste, sewage sludge and various organic and inorganic wastes (hereinafter referred to as "waste") in an environmentally friendly manner. Odors and gases generated are removed from the deodorization chamber and deodorization tower implemented at the ceiling of the waste treatment plant, and the sewage generated during the deodorization process is recycled and recycled in an environmentally friendly manner by aeration and purification plants in the sewage purification plant. To prevent pollution, improve the work environment of the treatment plant, improve workability, and raise various kinds of vegetables, fruit water, purified plants (lotus, parsley) and fish in the sewage purification room to increase the purification power of sewage as well as additional income. While using hot water, especially waste heat from the fermentation process, On the low winter it relates to environment-friendly waste disposal system for heating the firebox ohsujeong.

In general, food waste generated in homes and restaurants contains a large amount of water and nutrients, so it is easy to rot, and as a result, odors and pests are generated, resulting in environmental pollution. Even though landfills are buried, odors and leachate from corruption are generated, and environmental pollution cannot be avoided, resulting in huge waste of resources.

In addition, a large amount of livestock waste (manure) generated from livestock farms is bad smell, pests multiply and cannot be used as agricultural compost, and when discharged into rivers, it causes water pollution, Pollution is a serious social problem.

Therefore, in recent years, organic wastes have been collected from homes, restaurants, and livestock farms and produced as organic fertilizers through aerobic fermentation process by microorganisms. In addition, the use of chemical fertilizers is improving the soil being acidified.
