If COD level in stripped water goes high,it would do no good to the stability of phenol-cyanide waste water treatment system.Analysis was made from overall process,with Coking Plant of Jiugang (Group) as an example.Measures were taken,such as coal blend ratio was optimized and free space temperature on oven roof was adjusted,which could eventually stabilize the COD level in the stripped water.Biological index were adjusted to the extent that the normal metabolism of micro-organism can stay away from influence and its effluent can remain stably acceptable.
