摘要:<p>PROBLEM TO BE SOLVED: To treat waste water relatively high in the concn. of a sulfur compd. by simple constitution. SOLUTION: In an apparatus for methane fermentation consisting of an acid forming tank 1 for decomposing an org. substance in org. waste water to lower fatty acids by acid producing bacteria and a reaction tank 2 further decomposing the lower fatty acids into methane and carbon dioxide by methane bacteria, as a ventilator for ventilating the gas in the acid forming apparatus 1, for example, a gas sending-out fan is equipped. By this constitution, the volatilization of hydrogen sulfide formed in the liquid phase of acid forming tank 1 to a gaseous phase is accelerated and the sulfur compd. can be efficiently removed from the liquid phase.</p>
