NOVELTY - Apparatus has plant and fermentation tank in the plant. The fermentation tank includes storage tank, mixing tank, primary fermentation tank, secondary fermentation tank, aging tank and finished product tank. The corrugated baffle is mounted at top of the plant. The spacers and gutterways are arranged around the plant. The plant comprises inflation and oxygen supply pipes which is connected with porous stainless steel pipes of all the tanks.    USE - The apparatus is useful for disposing organic garbage from kitchen and bathroom (claimed).    ADVANTAGE - The apparatus is convenient to use and environmentally-friendly, enables rapid fermentation of organic garbage, and improves economic benefit of fermented organic garbage.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method of disposing organic garbage from kitchen and bathroom, which involves (a) storing organic garbage in the storage tank, which is fully mixed with compost from the finished product tank in the mixing tank, where water content of the mixture is 55%, and turning the compost to primary fermentation tank, and treating the subsequent organic garbage, (b) inserting porous stainless steel pipe in compost of the primary fermentation tank for inflation and oxygen supply, turning the compost once every day, and heating the compost in the presence of mesophilic microorganism, increasing temperature of the compost while evaporating water from the compost after 8 days, increasing temperature of the compost to about 50 degrees C, and turning the compost into the secondary fermentation tank, (c) adding two compost from the primary fermentation tank to the secondary fermentation tank, inserting porous stainless steel pipe in the compost of the secondary fermentation tank for inflation and oxygen supply, turning the compost once every day, and performing secondary fermentation for 7 or 8 days, evaporating water of the compost, reducing the quantity of the compost, increasing the compost in fertilizer efficiency and humus, and turning the compost to the aging tank for stable rotting, (d) gradually cooling the compost in the high temperature area in the phase of rotting, weakening activity of microorganism by reducing oxygen and stopping oxygen supply, reducing water content of the mixture to 35%, decreasing temperature of the compost, rotting the compost under stable condition for 7 or 8 days which gradually turns into fertilizer, and turning the fertilizer to finished product tank, and (e) reducing water content of the compost to 33%, and cooling compost to environment temperature, and obtaining compost as finished product which is mixed with new input organic garbage for next fermentation cycle.
