摘要
用焦化厂自产的熄焦粉对生化后的废水进行吸附处理 ,出水COD从 2 33mg/L降至5 0mg/L ,达到GB8978— 1996一级排放标准 ;用熄焦粉与微生物联合曝气处理焦化废水 ,出水COD从 10 86mg/L降至 119mg/L。
The effluent of biological treatment plant for coking wastewater was treated by adsorption process using extinguishing coke powder from the coke oven plant. The COD is decreased from 233 mg/L to 50 mg/L, which can meet the first grade discharge standard in GB8978-1996. The coking wastewater was treated by extinguishing coke powder adsorption bioaeration process with the reduction of COD from 1086 mg/L to 119 mg/L.
