| 摘 要： | 为研究在常规处理单元中实现浊度和重金属污染物同时达标的可能性,基于表面络合(吸附)理论及物料衡算原理建立了重金属污染物在常规净水工艺单元的去除模型,分析了工艺参数与重金属污染物出水浓度及其健康风险的关系,提出了减少健康风险的工艺调控方法及基于健康风险的净水工艺选择原则。结果表明,当原水重金属超标时,应优先选择通过合理调整常规净水工艺的投药量、改变药剂种类和配比、调整滤池滤速等工艺参数使浊度与重金属污染物同时达标的方案,若调控工艺参数不能消除出水重金属的健康风险时,要考虑设置后序深度处理单元。 |

| Abstract: | In order to investigate the possibility of making turbidity and metal pollutant to achieve the standard synchronously by conventional process,the model of heavy metal pollutant purification by conventional process were established according to superficial complexation (adsorption)theory and mass conservation principle,and the relations between the process parameters and the concentration or health risk of metal pollutant in purified water were analysed,and the controlling method adjusted to reduce the healt... |
| Keywords: | heavy metal pollutant conventional process surface complexation purification model health risk assessment |
