Description

【０００６】
【課題を解決するための手段】
このような従来技術における問題点を解決するために、請求項１に記載の発明は、有機性廃棄物の堆肥化設備において発生するガスの脱臭方法であって、上記ガスに含まれるアンモニアを接触液に吸収させ、該アンモニアを吸収させた接触液を微生物により硝化し、該硝化した液を微生物により脱窒し、上記脱窒により発生した窒素ガスを系外に放出することを特徴とする。この場合において、上記アンモニアの接触液への吸収と該接触液の硝化とを一の装置内で同時に行ってもよい。[0006]
[Means for Solving the Problems]
In order to solve the problems in the conventional art, the invention according to claim 1, a deodorization process gas generated in composting facilities organic waste, contact the ammonia contained in the gas The liquid is absorbed by the liquid, the contact liquid having absorbed the ammonia is nitrified by a microorganism, the liquid resulting from the nitrification is denitrified by the microorganism, and the nitrogen gas generated by the denitrification is released out of the system. In this case, the absorption of the ammonia into the contact solution and the nitrification of the contact solution may be simultaneously performed in one apparatus.

Claims

A deodorizing method of the gas generated in composting facilities organic waste,
Ammonia contained in the above gas is absorbed in the contact liquid, the contact liquid in which the ammonia is absorbed is nitrified by the microorganism, the nitrified liquid is denitrified by the microorganism, and the nitrogen gas generated by the denitrification out of the system The deodorizing method in the composting installation of the organic waste characterized by releasing.

In the deodorizing method in the composting facility for organic waste according to claim 1,
A deodorizing method in a composting facility for organic waste, characterized in that a part of the denitrified liquid is recycled as the contact liquid.

A deodorizing apparatus for deodorizing gas generated in an organic waste composting facility, comprising:
It is equipped with a gas-liquid contact device that absorbs ammonia contained in the above gas into the contact solution and simultaneously nitrifies the contact solution that has absorbed the ammonia by microorganisms, and a denitrification reaction device that denitrifies the above nitrified solution by microorganisms. Deodorizing device in organic waste composting facility characterized by

The deodorizing apparatus in the composting equipment for organic waste according to claim 3, wherein the clear water discharged from the denitrifying reaction apparatus is circulated and supplied as a contact liquid to the gas-liquid contact apparatus.
