摘要： PURPOSE:To treat waste water at a faster reaction rate by making reaction tanks smaller; minute particle carriers of 100mu or less, to which microorganism adhere, are suspended in waste water, introduced into the inner tank of double reaction tanks, and then put into the outer tank for sedimentation and separation. CONSTITUTION:Nitrogenated waste water, to which acid 2 and methanol 3 are added, is biologically treated in reaction chamber 7 while agitator 6 is rotated by motor 5. In this case, diatomaceous earth or kaolin (grain size 100mu or less) which sticks microorganisms easily and does not liquate any harmful object, is used as the carriers. The quantity to be used of the carrier grains will be 10-90% or preferably 30-60 capacity % of the virtual cubic volume of the reaction tank capacity. The biologically treated water will be put into settling tank 8 where the carriers are settled, and then passed through sludge blanket layer 9 installed at the bottom where the carriers are separated.

摘要： PURPOSE:To accomplish a decontamination of the object safely and easily without any waste production, by such a system that air, abrasive material and Flon liquid are jetted, through a nozzle, on the object followed by separation of the abrasive material which is washed with Flon liquid, the Flon gas generated being condensed to provide for reuse along with said abrasive material. CONSTITUTION:An object 2 is put in a closable decontaminating chamber 1, and a nozzle 3 is fed with, respectively, air from an air feed blower 4, Flon liquid from the corresponding storage tank 14 via a feed pump 15, and abrasive material from the corresponding storage tank 9 to mixing then together followed by jetting the resultant mixture through the nozzle 3 on the object 2 to carry out the decontamination. Thence, the air and abrasive material used and the Flon gas generated are suctioned by a blower 12 to feed to cyclone 6, where the abrasive material is separated from the Flon gas and the air followed by washing said material with Flon liquid in a slurry shifter 8 and sending it to the storage tank 9 to be provided for reuse. The Flon gas generated and the air are purified through a filter 11 followed by condensation with a condenser 13, the resulting Flon liquid being sent to the storage tank 14 for reuse, whereas the resultant exhaust gas being fed to the nozzle 3 with a pump 4 for reuse as the jet air.

摘要： PURPOSE:To avoid closure of powder bearing layer by bearing particles by supplying drainage in downstream flow to utilize a bearing fluidized floor floating on the water to thereby maintain high biological reaction speed so as to reduce the size of the device. CONSTITUTION:Drainage is treated by immersing powder bearing floawing on the water with lighter apparent specific weight than water in water, adhering biology thereto in floated state, introducing the drainage through the powder bearing layer in downstream flow, and treating it in contact with the biology upon passing thereof through the layer to thereby recover treated water layer from the bottom. According to this method, nitrogen gas produced by the denitrifying reaction becomes small bubbles to rise in the fluidized floor to eliminate the disadvantages of the conventional upstream flow method such as introduction of floating the bearing particles, the increase in the powder amount flown with the treated water, but to be preferable for formation of fluidized layer. Since it is aerobic treatment, the air fed from the bottom of the floor performs the same as the nitrogen gas as air bubbles.
