摘要： PURPOSE:To make the release effect of a biological membrane and the separation effect of caught SS(suspended solid) sufficient by simultaneously performing the drain of water from the bottom part of a treatment tank and the supply of washing air to the bottom part of said tank and disturbing the liquid level gradually falling in the tank by said washing air. CONSTITUTION:Air is supplied to the bottom part of a treatment tank 1 from an air source 5 such as a blower or an air compressor to be uniformly diffused into the water in the tank 1. Raw water to be treated is supplied to the treatment tank 1 from above from a storage tank 7 by a pump P and BOD or the like is treated with the bacteria of the biological membrane bonded to a packing material when the raw water passes through the packed bed 2 in the tank 1 as downward flow and SS mixed in the raw water is simultaneously collected and removed by the packed bed 2 while treated water is drained to the outside from the bottom part of the treatment tank. By this method, washing can be performed only by air without using washing water and excellent washing effect is obtained.

摘要： PURPOSE:To obtain treated water wherein fluoride is highly removed by mixing raw water containing fluoride with a precipitate containing Mg(OH)2 and CaCO3 to adjust the pH of raw water to 6.5 or less. CONSTITUTION:In the first process, raw water is introduced into the first reaction tank 1 from a raw water introducing pipe 11 and the precipitates of the first sedimentation tank 3(third process) and the second sedimentation tank 5(fifth process) are respectively introduced into the first reaction tank 1 from return pipes 12, 13 and sulfuric acid (H2SO4) is added to the reaction tank 1 from a chemicals injection pipe 14 to adjust the pH of raw water to 6.5 or less, pref., 4-6.5. When the pH of the raw water is adjusted to 4-6.5 by the addition of H2SO4 in the first process, an acid-resistant container becomes unnecessary and, since the return precipitate is not perfectly dissolved, seed crystal effect is developed with respect to the CaSO4 scale in the first process to prevent the generation of scale. As a magnesium compound to be added, magnesium oxide, magnesium hydroxide or magnesium chloride can be used.

摘要： PURPOSE: To effectively and highly treat water containing a fluoride ion, by producing sediments under the presence of a magnesium ion and by separating the sediments.
CONSTITUTION: At the first process, a crude water is introdiced to the first reaction tank 1 from a crude water pipe 5, and pH of the crude water is adjusted to 5W8.5 under a condition where calcium ions and/or aluminium ions exist. When pH of the crude water is adjusted, sediments are prodiced. The reacted liquid in the first reaction tank 1 is separated into a solid and a liquid in a precipitation tank 2. The sediment thus obtained is discharged to the outside of the process line through a sludge discharging pipe 8, and the supernatant liquid is introduced into the second reaction tank 3. At the second process, pH of the liquid introdiced from the first process is adjusted to ≥9.5 under the presence of magnesium ions and sediments are produced. The reacted liquid in the second reaction tank 2 is separated into a solid and a liquid in a precipitation tank 4. The supernatant liquid is discharged to the outside of the system through a treat water pipe 11 and a neutralization treatment is performed on the liquid if necessary. The sediments are returned to the first reaction tank 1 through a returning pipe 12 in the third process.
