ある。PRIOR ART The most effective method among the various conventionally known methods for composting sludge is to mix the sludge with dry compost powder, etc., adjust the water content to an appropriate moisture content of 40 to 50% by weight, and then mix the sludge into compost. When the sludge is put into a vertical reaction tank and forms a sediment layer therein, when reactive gases such as 9 air, oxygen, and oxygen-containing gases are passed through the sediment, aerobic microorganisms proliferate in the sludge. In this method, sludge is reformed into compost-like material by activating microbial and respiration activities.

The lid 7a, which can be opened and closed, was opened and the mixture was poured into the reaction tank. Lid 7
A was closed, and a blower 8 attached to the reaction tank was operated slowly to blow air into the reaction tank 5 through a pipe 9. (The air that has passed through the layer of material to be treated is oxidized through a pipe.) Carbon dioxide gas is removed by a tank 10 filled with an aqueous IJ solution, and then ammonia is removed by sending sulfuric acid into a tank 11. The water is washed in the tank 12 filled with water (2), and the water is removed by the heat pump dehumidifier 15 (2). Immediately, heat generation due to the Vc microbial reaction began, and after 24 hours, the temperature of the object to be treated reached 75° C. at the highest temperature portion.

It was compost VC. Put this in the dryer 17
A portion of the sludge was dried to a moisture content of 15% and shipped as a product, and a portion was crushed in a crusher 18 and used to adjust the moisture content of the next raw material sludge.

対象も別種の物質であることもある。The success of this example can be ensured by controlling the temperature, humidity, flow rate, oxygen injection amount, etc. of the reaction gas flowing into the reaction tank, but information for control and 1. The temperature, moisture content, etc. of the object to be treated are measured by sensors inserted into various parts of the accumulation layer of the object to be treated, and the temperature, humidity, flow rate, carbon dioxide concentration, and oxygen of the reaction gas at various points are measured. Concentration, ammonia concentration, etc. may be measured and control may be performed using a computer or other means based on this information. Since both ammonia and carbon dioxide gas in the reaction gas are easily dissolved in liquids such as water, they may be largely removed by washing with water, without using sulfuric acid or an aqueous solution of caustic soda. It is convenient to use water flowing out of a heat pump dehumidifier as the liquid for this purpose.
Preferably, the structure of the heat pump type dehumidifier is improved so that ammonia and carbon dioxide gas can be removed simultaneously with dehumidification or immediately following it. There are no restrictions on the method for removing ammonia and carbon dioxide, and the objects to be removed may also be different types of substances.

The shape of the reaction tank is preferably tapered toward the top. The inner surface of the reaction tank and the inner surface of the lid are sometimes coated with Teflon to prevent condensation. In the previous example, the reaction vessel was made of a steel plate with a corrosion-resistant lining. There may be a plurality of reaction tanks and dryers, and there are also cases where the reactors and dryers are stacked upward in multiple stages. There are no restrictions on the method of drying after composting. Although the definition of a composting reaction is problematic, one reaction process is carried out in the presence of oxygen.
