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.

In a water treatment apparatus, the time for treatment after water to be treated is introduced into an electrolytic bath is reduced. The water to be treated in a reservoir is subjected to electrolysis at a first electrolytic bath. Electrolysis is carried out at respective first and second electrolytic baths. By the electrolysis at the second electrolytic bath, hypochlorous acid is generated from chloride ions at the anode side. The solution subjected to electrolysis at the second electrolytic bath is mixed at a predetermined site of the pipe connected between the reservoir and the first electrolytic bath with the water output from the reservoir via a pipe prior to introduction into the first electrolytic bath. Accordingly, the water subjected to electrolysis at the first electrolytic bath can be sterilized in advance by the hypochlorous acid generated by electrolysis at the second electrolytic bath.

A water treatment apparatus includes a storage unit storing water to be treated including a pharmaceutical drug, an apply unit applying the water to be treated to the storage unit, an addition unit adding into the water to be treated metal salt generating halide ions when dissolved in the water to be treated, and an energizing unit applying a current to a pair of electrodes immersed in the water to be treated in the storage unit. The pharmacological activity of the pharmaceutical drug is eliminated or reduced by decomposing or altering at least a portion of the chemical structure of the pharmaceutical drug included in the water to be treated through electrolysis.

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.

A method of detecting abnormalities in flow rate in pressure-type flow controller. The method checks the flow rate for abnormalities while controlling the flow rate of fluid in a pressure-type flow controller FCS using an orifice—the pressure-type flow controller wherein with the upstream pressure P1 maintained about two or more times higher than the downstream pressure P2, the downstream flow rate QC is calculated by the equation QC=KP1 (K: constant) and wherein the control valve CV is controlled on the basis of the difference signal QY between the calculated flow rate QC and the set flow rate QS.
