| 摘 要： | 以京杭运河常州段微污染原水为研究对象,对其进行常规处理的同时增投粉末活性炭(PAC),通过静态吸附试验考察了最佳的投炭点和投加量.结果表明,投炭点在净水工艺流程中越靠前,则PAC对污染物的吸附效果越好;增投粉末活性炭可大幅度提高对有机污染物的去除效果;粉末活性炭的最佳投加点为吸水井,最佳投量为30 mg/L.

| Abstract: | Taking micro-polluted raw water from Changzhou section of Beijing-Hangzhou Grand Canal as study object,powdered activated carbon(PAC) was added when the micro-polluted raw water was treated by conventional process.The optimal PAC dosing point and dosage were investigated by static adsorption test.The results show that the pollutants adsorption efficiency by PAC increases when PAC is dosed into the forepart treatment process.The addition of PAC can greatly improve the removal efficiency of organic pollutants... |
