摘要
为解决外排焦化污水中COD和氨氮的超标问题,在对蒸氨系统进行改造的同时,将生化处理装置与A-O法生物脱氮工艺相结合,使外排废水全面达标排放。
In order to solve the over -standard d ischarge of COD and NH 3 -N in coking waste water.During the modificatio n of ammonia stripping system,the bi ochemical treatment unit and A-O biological denitrifica tion process are combined,by doing t hese all the indexes of waste water discharged can meet th e standard.
