Title: Modeling of Heavy Metal Pollutant Purification in Conventional Process and Investigating of Health Risk of the Purified Water
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 health risk and the selection principle of the purification process based on the health risk were carried out. Results shows that the purification project to make turbidity and metal pollutant to achieve the standard synchronously by adjusting the parameters of conventional process such as the dosage of coagulant,the kinds and formulations of coagulant,and the filtration rate should be adopted firstly,and advanced treatment will be consider if the health risk would not be avoided by adjust the parameters of conventional process,when raw water is polluted by metal pollutant.
