粉末活性炭强化絮凝联用应急处理震后微污染源水

【摘要】 面临震后成都市沙河段微污染原水的水质情况,提供切实有效的应急处理措施,并为给水厂的粉末活性炭应急投加提供依据,通过烧杯试验确定了适宜的活性炭投加量和投炭点。结果表明,投加点在流程上越靠前越有利于活性炭吸附作用的充分发挥;活性炭与混凝剂的竞争吸附现象并不明显。活性炭的投量需根据不同水质情况通过试验确定,针对成都沙河段的原水水质,试验所确定的活性炭最佳投加量为10～15mg/L。更多还原

【Abstract】 Aim to the micro-polluted raw water situation of Chengdu sand-river after earthquake,provides the practical effective emergency processing measure,and for gives the water works the PAC intreatment to provide the basis emergency,through the jar test determined the suitable activated carbon quantity and the coal spot. The result indicated that,the dot depends on the flow is more advantageous to the activated carbon adsorption full display;The PAC and the coagulant competition adsorption phenomenon is not obvious. The activated carbon throws the quantity to have to act according to the different water situation through the experimental determination,in view of the Chengdu sand-river original water quality,the activated carbon which the laboratory determined throws the increment is 10～15mg/L best.更多还原
