摘要： PURPOSE:To remove efficiently phosphate ions with a high removal rate over a long period of time by reactivating an aluminum-contg. granular material by an alkali agent and adding the waste liquid of the reactivation as an aluminum compd. to raw water. CONSTITUTION:Phosphate ion-contg. water is passed through a packed bed of the aluminum-contg. granular material under the condition of 3-8.5pH in the presence of the aluminum compd. The packed bed is intermittently developed and washed by upward current in the mid-way of such passing and when the activity thereof decreases, the aluminum-contg. granular material is reactivated by bringing said material into contact with the alakali agent. The waste liquid of such reactivation is added as the aluminum compd. to the raw water. The reactivation is repeated in the above-mentioned way and the raw water is dephosphorized stably and efficiently at a high rate for a long period of time.

摘要： PURPOSE: To remove phosphate in water in extremely good efficiency, by constituting contact layers each containing a phosphate adsorbent in one or more stages in the up-and-down direction in a vertical treating tower by water passable support plates while supplying water to the lower end in the treating tower to flow the same in an upwardly directed stream.
CONSTITUTION: A phosphate adsorbent is continuously or intermittently replenished to the uppermost stage contact layer by a supply pipe 6 and raw water is supplied to the bottom part of a tower from a water supply pipe 7 by a pump to be flowed in an upwardly directed stream while treated water is flooded over a flooding weir 12 from the upper part of the uppermost stage contact layer. In this case, the water passing linear speed of water is set to 5W30m/hr and the adsorbents of the upper stage contact layers are inhibited from mutually falling to the lower stage contact layers through a non-angle-of-repose nozzle 5 by the water upwardly flowed through the non-angle-of-repose nozzle 5. By this method, the phosphate adsorbent of each stage contact layer is fluidized in a boisterous state by the upwardly directed water stream and efficiently contacted with water to remove the phosphate in water by adsorption.

摘要： PURPOSE: To efficiently crystallizedly remove phosphates from water, by supporting powder containing calcium phosphate such as hydroxyapatite on a supporting body containing calcium carbonate such as a fossile coral to form the titled dephosphorizing agent.
CONSTITUTION: The interior of a tank for manufacturing a dephosphorizing agent is packed with calcium carbonate-contg. particles to form a stationary bed. The liquid suspension of powder containing calcium phosphate is cyclically circulated, until most of suspended matter is eliminated. Hence, said powder is captured in the stationary bed of the supporting body. Thereafter, phosphate- contg. water is circulated in a series or cyclically under the condition of a pH above 6, so that said powder is supported on the supporting body to obtain the artificial dephosphorizing agent. This dephosphorizing agent is brought into contact with phosphate-contg. water at a pH above 6 in the presence of Ca ion, to crystallize phosphoric ion in the form of hydroxyapatite on the dephosphorizing agent. Thus, dephosphorization is performed.

摘要： PURPOSE:To speedily accomplish a steady operation at the time of starting, by a method wherein a starting tube into which air is blown at a part of an air diffuser is provided in the interior of a lower end part along one side of a main tube, and a slit or a guide tube is provided at the outside surface of the starting tube. CONSTITUTION:For starting, air is blown into the interiors of an upward flow passage 3 and the starting tube 9 by the air diffusers 8, 8' to achieve the same linear velocity of air in both the passage 3 and the tube 9. As a result, carrier particles located beneath the parts of a stacked layer 11 to which the tube 9 and a draft tube inside a downward flow passae are faced start to be circulated along with the local circulating flow of the blown air, so that the stack begins to crumble at these parts. When the crumbling of the stack reaches the lower end part of a partition wall 9', an upward circulating flow through the passage 3 is generated, then the particles stacked at the lower parts of the passage 3 and the downward flow passage start to be circulated together with the circulating flow, resulting in the steady operating condition.
