When liquefying and decomposing wastewater containing organic substances such as food crushed solids and fats and oils with a grease trap, the organic substances also contain difficult-to-decompose substances that are difficult to liquefy and decompose. This accumulates downward, and if it is not taken out of the grease trap, a large amount of gas is generated, which causes a bad smell. In addition, the oil and fat exist in an emulsified state, and when the oil and fat are in a large amount, they are less likely to be dissolved and decomposed, and the floating oil and fat and organic substances are rotted, bacteria are propagated, and a bad odor is caused. When it is discharged into sewage, etc., it contains a large amount of organic substances,
If the OD and SS values are high and the effluent is discharged without being sufficiently treated, it will cause pollution problems such as water pollution.

However, taking out the sludge accumulated in the grease trap is a very troublesome and difficult work, so it is neglected, and it is naturally discharged without being able to prevent the generation of oil stains and odors. The wastewater will also contain undecomposed sludge. Therefore, microorganisms and drugs are administered to the grease trap, and the microorganisms solubilize it in the liquid, but it is also possible to artificially supply a fixed amount to the grease trap periodically and manage it. Practically impossible.

From the above point of view, the present invention facilitates solubilization of organic matter, fats and oils, etc. in purification of wastes containing garbage, such as organic substances such as crushed food solids, fats and oils, and sterilization of wastes containing garbage.・ Let's provide a treatment device for wastewater containing garbage that cleanses and deodorizes, facilitates the maintenance of the device, and clarifies the treated water that is discharged without causing pollution such as water pollution.
