摘要： A waste treatment system permitting treatment of organic wastes at low cost is provided. In the waste treatment system, organic wastes such as sewage, garbage and sludge are introduced into a methane fermentation bath for anaerobic fermentation. The methane gas produced in the bath is refined in a gas holder and then supplied to an electric generator, where the methane gas is used as a raw material for power generation. Digested liquid within the methane fermentation bath is supplied to an electrolytic bath via a flow adjustment bath and a fine screen. In the electrolytic bath, the digested liquid is subjected to electrolysis, by applying potentials to an electrode pair in the electrolytic bath based on the electric power obtained by the electric generator. By the electrolysis, nitrogen components including organic nitrogen and ammonia nitrogen, and BOD, SS and phosphorus components are removed from the digested liquid.

摘要： The object of the present invention is to provide a water treatment device in which temperature does not affect performance in nitrogen removal. Water circulates in a first anaerobic filter bed chamber 5, a second anaerobic filter bed chamber 10, a contact aeration chamber 14, a sedimentation chamber 19, and an electrolytic chamber 59 for phosphorus removal. The supernatant in sedimentation chamber 19 flows into a disinfection chamber 21 and is then sent to an electrolytic chamber 100 for nitrogen removal. An electrode pair is provided inside electrolytic chamber 100. Halogen ions present in the water are oxidized on the anode side. After halogen gas is generated, this gas reacts with water and generates hypohalous acid. On the cathode side, the nitrogen components in the water are converted to nitrate ions, and these nitrate ions are further converted to ammonium ions. The hypohalous acid and ammonium ions react, and the nitrogen components are converted to nitrogen gas by way of chloramine.
