摘要
在焦化污水处理工艺中,通过对亚硝酸型反硝化生物脱氮与硝酸型反硝化生物脱氮工艺的比较,探讨了需氧量、耗碱量及投资降低的机理。试验得出的优化方案是以NaOH为碱源的亚硝酸型反硝化生物脱氮工艺。
In the coking waste water treatment process,by comparison between nitro us acid type denitrification biological nitrogen removal process,the mechanism of oxygen demand,soda consump-tion and lower investment is studied.The optimal proposal obtained from the test is the nitrous acid type denitrification biological ni trogen removal process in which NaOH is used as soda source.
