壬基酚在活性污泥曝气池中的迁移转化行为研究

以实测地形资料和水环境资料为分析研究的依据,采用水流、水质数学模型对余姚城镇污水经处理后,尾水排钱塘江河口的水环境影响进行综合分析评价,推荐优化入江管工程布置方案,可为城市污水尾水河口处置分析研究提供借鉴.

Study of the removal for the Nonylphenol of municipal wastewater in an aeration basin

Basis on the analysis of Nonylpheoel (NP) in the aeration basin of a municipal wastewater treatment plant in Beijing, the behavior of the translation-conversion and the removal rate for NP were investigated with a sequence batch reactor simulating process. It showed that the remove process of NP in a municipal wastewater treatment plant was taken place in foreside of an aeration basin (aeration 0-3 h), the remove rate of NP was about 80%. The mechanism of remove process of NP includes both the adsorption and bio-degradation of active sludge, among which 79. 1% of the remove quantity was biodegraded and 20. 9% was by adsorption. The biodegradation of NP followed linearity dynamics process.
