摘要:

由于硫氰化物是影响焦化废水脱氮的主要因素,所以对焦化废水处理工艺进行改造时,在生化系统前增加了预脱氰池,有效降低了废水中硫氰化物的含量,以保证后续生化处理系统稳定运行。

Abstract:

Since thiocyanide is the most important factor influencing de-nitrification in the phenol cyanide effluent,pre-decyanation tank is therefore added before the conventional bio-chemical treatment system as modification,which can dramatically reduce the content of thiocyanide in the effluent to ensure a stable running of the downstream bio-chemical system.
