大型深水湖泊和水库普遍存在水温热分层现象，导致水质也存在分层现象，中间层或上下层混合水体水质比表层和底层水体水质好。结合具体实例，建立了双孔口混层取水水质分析模型，并利用模型成功分析了7种取水模式下的取水水质情况。研究结果表明，通过调节不同高度取水口的开度，可获得不同的供水水质；在所选择的实例中，工况3和工况4在相同条件下出流水质优于其余工况。研究结果对多孔口取水塔取水有指导意义。

Thermal stratification exists generally in large and deep reservoir and results in water quality stratification, and the water quality at middle layer or upper-middle layer is better than that at surface or bottom. In the combination of concrete case, water quality analysis model for dual water intakes is established and water quality for 7 water intake conditions are analyzed by the model. The simulation results show that by adjusting the openings of water intakes at different elevation, the different water quality can be obtained, especially the water quality of mode 3 and mode 4 is better than other modes under the same condition. The simulation results can provide guidance for water tower with multiple intakes.
