摘　　要：山区溪流作为水厂水源之一,其水量、水质的常年波动严重增加了水厂的运行负荷,而集蓄坝与岸滤组合取水技术作为一种经济的水处理工艺,通过河岸过滤截留浊质和去除污染物、通过集蓄坝截留和汇集溪流入渗水,可满足水厂对进水水量和水质的要求。探究了3种岸滤系统对不同水质原水的处理效果,结果表明,它们对有机物均有较高的去除率,且相较于砾石层、砂层来说,土石混合层的抗冲击负荷能力更好,并且对抗生素、农药等污染物具有更好的吸附性。Hydrus 2D/3D模拟结果证明,集蓄坝的设置能有效汇集地下水,保证渗井产水量满足水厂要求。可见,在一定条件下集蓄坝与岸滤组合取水技术普遍适用于山区溪流等水源的预处理。As one of the sources of waterworks,the perennial fluctuation of water quality and quantity in the streams in the mountainous areas has seriously increased the operating load of waterworks.As an economic water treatment process,the combined water intake technology of storage dam and bank filter can meet the requirements of influent quantity and quality of waterworks.The mechanism is that the bank can filter and intercept turbidity and remove pollutants,while the storage dam intercepts and collects the streams into the seepage water.The treatment effects of three kinds of bank filtration systems on different water quality were investigated.It was found that the three systems had high removal rates of organic matter.Compared with gravel layer and sand layer,soil‑rock mixed layer had better anti‑impact load capacity and adsorption performance of antibiotics,pesticides and other pollutants.Hydrus 2D/3D simulation results showed that the setting of the storage dam could effectively collect groundwater and ensure the water production of the seepage well to meet the requirements of the waterworks.This study confirms that under certain conditions,the combined water intake technology of storage dam and bank filter is generally applicable to the pretreatment of water sources such as mountain streams.
