摘要： PROBLEM TO BE SOLVED: To efficiently obtain treated water having excellent water quality by effectively improving the settleability, concentratability, and filterability of sludge in an activated sludge mixed liquor in a biological treatment tank by adding an iron salt. SOLUTION: In biological treatment of organic wastewater after adding an iron salt, the organic wastewater is subjected to decarbonation treatment, the iron salt is added to and mixed with the decarbonated water, and the mixed water is mixed with activated sludge to be subjected to the biological treatment. The decarbonation treatment of the organic wastewater beforehand prevents generation of iron carbonate, and mixing the organic wastewater with the iron salt at around the optimum pH of ferric hydroxide prevents turbidity of treated water due to generation of iron oxide and iron carbonate.

摘要： PROBLEM TO BE SOLVED: To provide a chemical washing method of an immersion type membrane separation device having a membrane module 2 arranged in a water tank 1 by conducting the membrane filtration of a water to be treated in the water tank 1 by means of a suction pressure and/or gravity difference, which does not need special equipment or working and which conducts the chemical washing of the membrane module efficiently and reduces the amount of the washing waste liquid with a simple method.
SOLUTION: The immersion type membrane separation device discharges the water to be treated to the outside of the water tank 1, and leaches the water to be treated to a primary side by starting to inject the chemical for washing to a secondary side when a part of the membrane of the membrane module 2 emerges from the surface of the water to be treated. The chemical for washing injected to the secondary side is leached to the primary side of the membrane from the membrane surface which has emerged. Since the water to be treated in the water tank is further discharged to the outside of the water tank, almost all the chemical leached to the membrane surface is retained on the membrane surface without contacting with the water to be treated and then flows down. Therefore, the high chemical washing effect is obtained by the washing chemical with a sufficient concentration. The water to be treated discharged from the water tank does not become the washing waste liquid because there is almost no inclusion of the chemical.

摘要： PROBLEM TO BE SOLVED: To provide a membrane treatment apparatus having a detecting means which detects an occurrence of membrane fracture without fail as well as at a low cost.
SOLUTION: When a hollow fiber membrane 4 is fractured, a pressurized gas from a compressor C flows through a fractured part into a treating room 12 and passes a detecting part for membrane fracture 50. An electric current or voltage between an electrode 54 and 55 varies in case of existence of a bubble in a treating water. The occurrence of membrane fracture is detected by this varying pattern. A groove 53 is disposed on a ceiling surface part of a short conduit 51 and the electrodes 54 and 55 is provided in the groove 53 in order for the bubble to contact with the electrodes 54 and 55 without fail.

摘要： PROBLEM TO BE SOLVED: To obtain coagulation-treated water with a low concentration of dissolved aluminum and dissolved organic materials by preventing the coagulation from being hindered by coagulation hindering materials in raw water through appropriate control of the amount of inorganic coagulants added in coagulation, and by a stable and efficient coagulation with a small amount of inorganic coagulants through appropriate control of the amount toward the required minimum.
SOLUTION: When a separated liquid obtained by solid-liquid separation of water to be coagulated is subjected to pressurizing- or sucking-filtration through a filter under a predetermined pressure, a filtering time required for filtering a predetermined amount of the liquid to be separated, a filtration performance defined by the amount of filtered water which can be filtered in a predetermined time, and the ratio of a variation with time of the filtration performance are detected. When the detected filtration performance and the detected ratio of variation with time of the filtration performance satisfy predetermined reference values, respectively, the amount of inorganic coagulants added is kept in a predetermined reference value. When the detected filtration performance or the detected ratio of variation with time of the filtration performance does not satisfy the corresponding predetermined reference value, the amount of the inorganic coagulants added is adjusted.
