摘要： PROBLEM TO BE SOLVED: To make efficiently performable the methane fermentation of an easily degradable organic waste and to make efficiently treatable excess fermentation sludge. SOLUTION: At the time of performing the methane fermentation by successively sending the easily degradable organic waste such as garbage to an acid fermentor 16 and a methane fermentor 19, the excess fermentation sludge having a proper concentration is kept in the methane fermentor 19 by drawing the excess fermentation sludge 21 in the methane fermentor 19 and extracting a fermentation liquid 27 from the fermentation sludge 21 in the vessel by a membrane separation device 26. The acid fermented material is the acid fermentor 16 is conditioned by dehydrating the drawn fermentation sludge 21 without charging chemicals by a centrifugal dehydrator 22 and returning the separated dehydration filtrate having high released SS concentration and alkalinity to the acid fermentor 16. As a result, the fermentation liquid 27 enables to be sent to a water treating process and to be treated. The acid fermentation is accelerated by the dehydration filtrate 24 to accelerate the methane fermentation.

摘要： PROBLEM TO BE SOLVED: To efficiently utilize carbides, which are treatment products of organic wastes. SOLUTION: After being flocculated by an iron-type flocculant 7 and dewatered, digestion sludge 6 generated by fermentation of organic wastes is carbonized to recover a carbide 11 containing a iron oxide-type compound derived from the iron-type flocculant 7 and capable of carrying out desulfurization. In the case the recovered carbide 11 is packed in a desulfurization tower through which an object gas such as methane gas is to be passed, H2 S contained in the object gas reacts with the iron oxide-type compound capable of carrying out desulfurization to be converted into iron sulfide and together with other sulfur compounds and water, the iron sulfide is adsorbed on the porous carbide and removed.
