摘要： PROBLEM TO BE SOLVED: To provide a treatment method of methane fermentation residue capable of reducing the amount of a flocculant used in the treatment of methane fermentation residue to reduce the treatment cost and capable of easily composting dehydrated sludge, and an equipment therefor. SOLUTION: After ammonia is removed from fermented residue from a methane fermentation tank 10 by an ammonia diffusion column 20, a flocculant is added to the residue in a sludge separator 30 and the residue is dehydrated to be separated into sludge and a filtrate. The ammonia diffusion column 20 has a liquid feed means for receiving the residue from an upper introducing port 21 to lead out the same from a lower lead-out port 22 and an aeration means introducing steam or air from an air introducing port 23 to aerate ammonia.

摘要： PROBLEM TO BE SOLVED: To provide a methane fermentation method and an apparatus which can perform methane fermentation stably for a long time by preventing an organic waste feeding line from being clogged. SOLUTION: Electromagnetic induction type conductance meters E1, E2 measuring the electric conductivity of the organic waste circulating in the feed lines and a cleaning means cleaning the insides of the feed lines are arranged in the feed lines L1, L6 of the organic waste. The cleaning means carries out methane fermentation by using the apparatus for methane fermentation designed to clean the feed lines when the measured values of the electric conductivity E1, E2 fall bellow the predetermined value, and the inside of the feed lines is cleaned when the measured values of the electric conductivity of the organic waste circulating in the feed lines fall below the predetermined value.

摘要： PROBLEM TO BE SOLVED: To provide a methane fermentation apparatus for organic waste which can stably methane-ferment organic waste with a high solid concentration, can make the whole system of the fermation apparatus compact, and has a high treatment capacity. SOLUTION: Immobilized microorganisms 43 packed in a methane fermentation tank 34 are composed of a meterial in which anaerobic microorganisms mainly consisting of methane fungi are supported on a carrier formed by knitting a synthetic resin wire rod in the shape of a string, a carrier of a synthetic resin polyhedron having the largest diameter or one side of 5-20 mm length or granules, or a biodegradable plastic carrier. The carrier is preferably hydrophilicized by an oxidizing agent, and the oxidizing agent is preferably ozone gas. Preferably, the organic waste is circulated in the methane fermentation tank 34, a gas produced by the methane fermentation is introduced into the organic waste in the tank 34, and the waste is methane-fermented while being agitated mechanically, for example, with agitation blades 51.
