盘脚盘的顺口溜摘要：PURPOSE:To treat the waste water from dye works efficiently and inexpensively by a method wherein raw water is at least subjected to removal of org. substrnaces and, then the treated water is subjected to adsorbing treatment in an adsorbing treatment using activated carbon and, thereafter, subjected to oxidation treatment using ozone. CONSTITUTION:The waste water of dye works of which COD is 430mg/l and chromaticity is 3,800 is subjected to biological oxidation treatment to obtain the treated water with COD of 190mg/l and chromaticity of 3,000. Said treated water is subjected to coagulating and precipitating treatment and succeedingly subjected to filtering treatment and, after the treatments the obtained filtrate is pasd through a column packed with particulate activated carbon to be subjected to activated carbon adsorbing treatment. Next to this treatment, ozone oxidation treatment (an ozone injection amount is 20mg/l) is applied to said treated water to obtain the treated water of which COD is 60mg/l or less. By this method, an adsorbing amount of COD and chromaticity components to the ac tivated carbon becomes twice or more as compared to the conventional methods and a ud amount of the activated carbon can be reduced considerably and a treating cost is lowered to 2/3 or less as compared to a conventional cost.
