摘要： PROBLEM TO BE SOLVED: To obtain a method and an apparatus for aerobic treatment which can reduce the treatment cost and the phosphorus concentration in a treated water by carrying out an aerobic treatment using phosphorus contained in sludge efficiently to reduce the amount of added phosphorus and the amount of generated surplus sludge. SOLUTION: A water to be treated is subjected to an aerobic biological treatment in the presence of a biosludge in an aeration tank 1. The treated liquid is subjected to solid-liquid separation in a solid-liquid separation tank 2, and the separated sludge is returned to the aeration tank 1. After adjusting the pH of the sludge separated in the aeration tank 1 or the solid-liquid separation tank 2, the sludge is reformed to be easily biodegradable by ozonation etc. in a reforming tank 4. Before introducing the reformed liquid into the aeration tank 1 and subjecting it to the biological treatment, a phosphorus insolubilizing agent is added to the reformed liquid and/or the biologically treated liquid to insolubilize phosphorus, and then the liquid is introduced into the aeration tank 1 to retain it during a biological treatment process, thereby phosphorus contained in the sludge is efficiently used to perform the aerobic treatment.

摘要： PROBLEM TO BE SOLVED: To cetainly prevent the generation of calcium carbonate scale by a minium necessary addition of an acid in a method performing biological denitrification treatment in a denitrification reaction tank by adding an aid to calcium nitrate-containing waste water. SOLUTION: In performing biological denitrification treatment in a denitrification reaction tank by adding an aid to calcium nitrate-containing waste water, the amount amt. of addition of the acid (hydrochloric acid) is controlled corresponding to the nitrogen load amt. of a denitrification reaction tank. In actual treatment equipment, the concn. of nitrogen of calcium nirate- containing waste water being raw water and the amt. of water are continuously measured and the inflow nitrogen load amt. to the denitrification reaction tank is calculated and the addition amt. of hydrochloric acid is operated by multiplying the nitrogen load amt. by the coefficient of hydrochloric acid to nitrogen calculated by a preparatory experiment preliminarily performed by using raw water and the addition control of hydrochloric acid is performed on the basis of this result. By this constitution, since the control of the proper charging amt. of hydrochloric acid can be performed on the basis of the nitorgen load amt., the generation of calcium carbonate scale can be certainly prevented.

摘要： PROBLEM TO BE SOLVED: To prevent the rise of the upper boundary of sludge blanket(SB) and the flow-out of the sludge blanket into treated water by making adjustable the height of the heed port of treated water which is arranged in a way that the treated water passes through the sludge blanket formed in the vessel. SOLUTION: This solid-liquid separation vessel 1 is provided with a multi- stage inner cylinder-type feed well 4, and a movable wall 4B, which slides in contact with the fixed wall 4A of the feed well 4, is moved up and down through a hanger 6 by a hoist 5 corresponding to the height of an SB interface. The position of an opening 4S of the feed well 4 is moved up and down to change the height of the feed port from which sludge mixture liquid is injected into the separation vessel 1. At this time, the height of the SB boundary is measured by a sludge boundary detector 7, and the movable wall 4B is moved up and down by the operation of the motor 5M of the hoist based on such a measured result. By this method, solid-liquid separation can be achieved efficiently with a high water-surface area load even in the case of active sludge and flocculated sludge of slow settling velocity.
