摘要
用活性污泥法处理焦化污水,将一年内监测的曝气池山水和入水中酚、氰、氨氮、COD等指标建立数据库,并进行时间序列、正态分布性、自相关和线性回归分析.统计分析结果表明,多数指标呈正态分布而周期性特征不明显;经多元线性回归分析,出水COD与入水COD、出水酚之间的关系较为密切.
A database was set up to hold the routine monitoring results of phenol, CN, COD, NH3-N concentrations in effluents and influents of the aeration tank of an activated sludge process for coke-chemical wastewater treatment. The outputs of time series analysis and frequency distribution analysis based on those data indicated that the majority of data are best fitted by a normal distribution while no periodic behavior was observed. The effluent COD was significantly correlated with influent COD and effluent phenol.
