Abstract:
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.
