IPC: C08F2/46
Filed: 1992-02-13
Abstract: PURPOSE:To coat a tube with an organic thin film on its inside surface by setting a tube in which a gas is flowing in a cylindrical reactor, controlling the gas pressures inside and outside the tube and converting an organic compound and a non-polymerizable gas into plasma. CONSTITUTION:A tube 2 is set through the joint 3 to the inside of the cylindrical reactor 1.

Abstract: PURPOSE:To prevent release of ozone to the atm. by calculating the actual value of a decreased COD load value from the COD value of activated sludge treated water and the COD value after an ozone treatment and controlling the amt. of the ozone to be generated from this calculated value. CONSTITUTION:The ammonia water generated in a coke furnace is passed through an activated sludge treating chamber and a settling chamber, by which the ammonia water is purified. The supernatant water thereof is introduced into a reaction chamber 5, where the COD is removed by reaction with the ozone from an ozone generator 3. The ozone consumed in this reaction chamber 5 is subjected to sepn. of the unreacted ozone in an ozone separating chamber. The unreacted ozone is subjected to ozone cracking in waste ozone cracking equipment 9 and thereafter, the ozone is released to the atm. At this time, a deviation between the inlet side COD and the outlet side COD and the decreased COD load quantity from the volume of the treated water are calculated in an ozone concn. control section 18. The optimum amt. of the ozone to be generated is calculated from the measured values of the load quantity and the waste ozone concn. and the flow rate of raw material oxygen is controlled. The generated ozone canon. is lowered according to the excess rate of the waste ozone concn. if the waste ozone concn. is above 2mg/l.
