摘要： PURPOSE: To make a structure simple and enable mass production to be carried out at low cost by binding many flexible ring-like forms of synthetic resin at a specified position into an elastic string-like filter medium and constituting a microbe carrier for a floating bed of the filter medium. CONSTITUTION: This microbe carrier for a floating bed 1 is composed of an elastic string-like filter medium 6 obtained by binding the part of a flexible ring-like form in the direction crossing with the faces of the ring-like forms of synthetic resin to form the elastic string-like filter medium 6. The elastic string-like filter medium 6 of a specified length is of such a double annular form that both ends of a cut piece replicated into the center of the cut piece. The microbial carrier 1 for the floating bed is submerged into water to be treated in a water treatment tank 2 for batch process. When aerating the water, a gas supplied from a compressed gas source 5 is injected into the water using an aeration/stirring machine 7, and the water is stirred and fluidized by the gas. Consequently, the carrier 1 moves due to this fluidization action, so that microbes carried by the carrier 1 come into contact with the water to achieve water purification. The treated water is discharged through a discharge device 4.

摘要： PURPOSE: To efficiently remove iron in waste water with simplified equipment, by adding an oxidizing agent to iron-contg. waste water, aerating said waste water, adding a flocculant to it, passing it through an agitatively mixing water channel to flocculate said iron, and then precipitating the iron in a flocculative precipitation basin.
CONSTITUTION: After an oxidizing agent such as sodium hypochlorite (a) or hydrogen peroxide is added to iron-contg. waste water, the iron-contg. waste water is forcedly oxidized by aeration to form fine ferric hydroxide. Thereafter, an inorganic flocculant (b) such as poly(aluminum chloride) is injected into the waste water, and the waste water is agitated in an agitatively mixing water channel to flocculate ferric hydroxide. Then, a macromolecular flocculant (c) such as kuri Flock EDP-301A is injected, and the waste water is agitated in an agitatively mixing water channel to form bulky flocks. Finally, the flocks are separately precipitated in a precipitation basin, and a supernatant liquid is drained. Since power requiring parts are reduced to the least extent, this method can be easily executed in a site of construction work, and the removal of an iron is facilitated.

摘要： PURPOSE:To make the maintenance control easy and to improve the treating efficiency, by changing the arrangement density and interval of contact material corresponding to BOD concentration of influent waste water. CONSTITUTION:Clogging of the contact material 7 by the living things film sludge, is prevented by lowering the density of the material 7 by enlarging the inserting arrangement space of the contact material frame 6 or enlarging stretching space of the material 7, because waste water flowing in the first oxidation vessel 1, has a highest BOD concentration. The waste water is sent to the second oxidation vessel 3 after separating the mixed sludge in the first sludge separation vessel 2. BOD concentration is decreased in order of the second oxidation vessel 3 and the third oxidation vessel 5 and the clogging is difficult to happen and then, a high grade treatment is carried out by heightening the density of the material 7 and narrowing the space. Further, the sludge mixed in the waste water, is separated by providing the sludge separation vessel 4 between the second oxidation vessel 3 and the third oxidation vessel 5 when BOD concentration of the original waste water is high.
