摘要： PROBLEM TO BE SOLVED: To improve treated water quality and also to enable a highly loaded operation by arranging a flocculating and separating device at the upstream side of an aeration tank. SOLUTION: The flocculating and separating device C consisting of a mixing tank C1 having an agitating means 1i and a liq. chemical feed means 1j, a similar flocculating tank C2 and a flocculating and settling tank C3 is disposed at the upstream side of a membrane separation type activated sludge treating device A having the aeration tank A1 . A settled sludge at the flocculating and settling tank C3 is returned to the mixing tank C1 with a piping P2 . An SS component in a raw water W1 is flocculated and removed, and an SS concn. is reduced till an order of about 20mg/L. An accumulation of the SS component at the post stage aeration tank A1 is prevented by attaining this residual SS concn. A floculant such as aluminum sulfate and a pH adjusting agent such as sodium hydroxide are used at the mixing tank C1 of the flocculating and separating device C. A high-molecular floculant such as nonionic floculant is used at the flocculating tank C2 . In this way, the SS concn. is reduced and BOD components are removed sufficiently.

摘要： PURPOSE:To effectively prevent the generation of scales, by removing calcium from the filtrate resulting from solid-liquid separation after the addition of calcium compound to the water to be treated and sending at least a portion of the treated water back to the addition process for the calcium compound. CONSTITUTION:The method of treating the water containing fluoride ion and sulfate ion such as the waste water resulting from flue gas desulfurization comprises the steps of adding thereto calcium compound such as calcium hydroxide, adjusting the pH to cause a predipitate as required, obtaining filtrate by conventionally effecting solid-liquid separation, removing the precipitate from the water treating device, supplying a carbon dioxide containing gas to at least a portion of the filtrate for calcium removal therefrom and returning at least a portion of the filtrate resulting from the solid-liquid separation to the addition process for the aforesaid calcium compound. This method is effective in preventing the generation of scales.

摘要： PURPOSE:To enable stable denitriding treatment and also to simplify driving operation by detecting nitrogen removing velocity in a denitriding treatment tank and regulating amount of nitrogen load to be introduced into the denitriding treatment tank. CONSTITUTION:Pipelines 17, 18 for taking out liquid which are respectively provided with pumps 15, 16 are connected to a nitration tank 1 and a denitriding tank 2, and both nitrated liquid and denitrified liquid are respectively fed to a nitration velocity measuring device 19 and a denitriding velocity measuring device 20. The detection signals output from these devices 19, 20 are introduced into a controller 21 via signal lines 19a, 20a. The controller 21 treats these detection signals, and outputs a signal controlling amount of raw water to be introduced into a denitriding treatment tank A to a valve 5a via a signal line 21a. In other words, operation is performed in nitrogen load within the range of treatment capacity of microorganism and stable denitriding treatment can be performed even if the fluctuation of nitrogen load is caused. Further complicated driving operation for corresponding to the load fluctuation is not necessitated and the driving operation can be simplified.

摘要： PURPOSE:To efficiently remove boron, by a method wherein boron-containing water is treated by contact with an anion exchange resin and the used anion exchange resin is contacted with an acid to be regenerated while the waste liquid after regeneration is contacted with an extractant to extract boron. CONSTITUTION:Boron-containing water is supplied to an ion exchange tower 1 from a piping 11 to be treated by contact with an anion exchange resin and treated water is discharged out of the system from piping 12. At a stage wherein the anion exchange resin in the ion exchange tower 1 is saturated with boron, the supply of raw water is stopped and a regeneration liquid is passed through the anion exchange resin to elute boron exchanged and adsorbed by said resin. The waste liquid after regeneration is supplied into an extraction tower 2 from a piping 14 and contacted with an extractant to extract and remove boron. The extractant after the extraction of boron is treated with a counter extractant. The residual extractant is drawn out from a piping 15 to be reutilized. By this method, the effective utilization of a boron compound can be attained.

摘要： PURPOSE:To easily prevent the lowering in the activity of sludge, by holding the sludge in a biological nitration and denitrification treatment apparatus in the presence of a nitrate ion and/or a nitrite ion when the supply of load to said treatment apparatus is stopped. CONSTITUTION:In a biological nitration and denitrification apparatus, after steady operation is performed, the supply of raw water is stopped to stop the supply of load. In this state, sludges in treatment tank A-D are held in the presence of a nitrate ion and/or a nitrite ion. By this method, the activity of sludge is kept without lowering a nitration and denitrification speed.
