Description

[0001] SYSTEM FOR REFINING ORGANIC WASTE [0002]

The present invention relates to an organic waste refining system capable of effectively purifying organic wastes by firstly separating raw wastewater from organic wastes, heating and then separating the three phases, and purifying the separated wastes.

As is well known, organic wastes such as food wastes collected from households or businesses are subjected to a predetermined treatment process, and then, most of the organic wastes are removed from the solid material and incinerated and buried, or dried and fermented to remove organic fertilizer or compost .

The wastewater generated in the process of treating the organic wastes is treated mainly by a method of directly dumping the wastewater on the seawater using a ship or a purification treatment in a state where various sludges are removed by using a conventional wastewater treatment facility.

However, wastewater from organic wastes contains a large amount of oil components originating from fish, meat, and various kinds of oil products. When the oil component is not removed, it is contained in wastewater dumped on the pollution Which can lead to various environmental pollution due to the oily material and can cause a serious problem of destroying the ecosystem of the oceans.

Particularly, since the oily substance contained in the wastewater is composed of a refractory component and is not easily decomposed, it is difficult to obtain a satisfactory degree of purification when the wastewater treatment plant is used for purification treatment.

Furthermore, since the oily substance has a high viscosity, it easily adheres to the inner wall surfaces of various tanks and pipes of the wastewater treatment facility, which can cause a load in the wastewater treatment, thereby decreasing the treatment capacity of the wastewater and the efficiency of the facility .

In addition, since the oil material is stuck to the fluid tank or the pipe body during the wastewater treatment periodically, it must be removed periodically.
