摘　　要：蒸氨废水含高浓度的硫氰酸根会导致焦化废水中氨氮含量增高。剩余氨水直接蒸氨可以将蒸氨废水的硫氰酸根浓度从3876.45mg/L降至712.45mg/L,有效降低蒸氨废水中硫氰酸根的浓度,确保焦化废水处理系统的稳定运行。The high concentration of thiocyanate ions in ammonia stripping wastewater can lead to increased ammonia nitrogen content in coking wastewater.Direct ammonia stripping for residual ammonia water can reduce thiocyanate concentration in the stripping wastewater from 3876.45 mg/L to 712.45 mg/L,effectively lowering thiocyanate concentration and ensuring stable operation of the wastewater treatment system for the coke oven.
