By purifying by deodorizing and deodorizing the odor is safely invented.

Quicklime is a common name for calcium oxide, which is obtained by processing lime or baking hydroxide, but it has a function of natural digestion (calcination by pouring water in quicklime and making it into hydrated lime), which produces high heat when it comes in contact with moisture and hydrolyzes. Therefore, hydrolysis of organic waste and waste by using this action causes organic waste and waste to react with natural fire extinguishing agent, causing hydrolysis. In this process, high heat is generated and strong alkaline component acts. Wastes can be sterilized, disinfected and deodorized and digested to neutralize salt and toxicity.

Dolomite is dolomite or high-dilution as referred is a carbonate minerals reacted put in a lot of waste water as alkali many content of magnesium double salt of CaCo ₃ and MgCo ₃ reacted as calcium oxide is hydrolysed calcium oxide tipping the high temperature in the process As it has a digestive effect, the organic waste can be digested in a short time by removing salt and odor while disinfecting organic waste.

In the present invention, the natural fire extinguishing agent is added to a certain ratio so as to correspond to the amount of the object to be treated in a closed treatment chamber, and the reaction is stirred in a sealed state, thereby avoiding the action of steam pressure and strong alkali generated by the reaction heat and the reaction heat. The treatment is softened and sterilized, decomposed, salts and odors are removed and forced extinguishing is achieved in a short time, and the steam produced during the treatment can be used for wastewater purification.
