摘要
高浓度焦化污水经过生物、物化相结合的方法处理后 ,可使原水 COD从 12 0 0 0 m g/ L 左右、NH3— N从 12 0 0 mg/ L 左右分别降到 <10 0 m g/ L 和 <15 mg/ L,从而达到国家工业污水一级排放标准。
The high-concentration wastewater about 12 000 mg/L of COD and 1 200 mg/L of NH 3-N will be reduced below 100 mg/L and 15 mg/L respectively after treaed by process of combination of biological and physical chemistry treatment, and it win meet grade 1 of national discharging standard for industrial wastewater.
