摘要:
Hydrogen peroxide in a hydrogen peroxide reservoir is supplied to an effluent. Ozone gas generated in an ozone generating apparatus is delivered through branched piping to two ozone supplying points and is supplied to the effluent. The ozone and the supplied hydrogen peroxide react to generate hydroxyl radicals. The hydroxyl radicals react with the materials in the effluent to decompose and remove them.
摘要:
An ozone producing apparatus comprising an ozone generator, an adsorption/desorption tower, and an ozone desorbing means for desorbing adsorbed and stored ozone for supply, wherein the apparatus further includes an ozone density measuring means, and a control circuit for adjusting an amount of electric power for the ozone generator by comparing the measured value detected by the measuring means with a set value. A specified amount of ozone can be desorbed and treated in a stable manner in a just sufficient amount also in a case in which characteristics of the adsorbent or the ozone generator, temperature or degree of pollution of the water, multiplication speed of microorganisms or reaction speed of ozone should happen to be changed, so that adhesion of slime can be prevented in a stable manner over a long period.
