Abstract:

The process of phenol-cynaide-containing waste water treatment in coking plants is introduced.The reasons for the high ammonia nitrogen concentration in waste water after bio-chemical treatment of phenol-cynaide-containing waste water are analyzed.Based on the analysis result,improvement measures are taken,after which the ammonia nitrogen concentration meets the design requirement.
