摘　　要：针对江水源热泵系统取水量大可能对江水水质产生影响的问题,以嘉陵江重庆主城段水体为研究对象,采用物理模拟的方法对江水源热泵系统温排水进行了系统的试验研究.结果表明,温排水对排放口近水域水温和水质均有一定程度的影响.在模拟大型江水源热泵系统运行工况的条件下,温排水导致排放口附近水域水温上升约3.3℃,间歇运行时水温能得到有效恢复;温排水导致排放口局部水域溶解氧降低8%～12%;并能加快水中营养物质的循环,从而使水体的高锰酸盐指数升高;温排水有利于水体中的有机氮转化为氨氮,加速氮循环,从而使水体氨氮和总氮含量升高,但对总磷影响不显著.Large amounts of water withdrawal with water resources heat pump system have probably impact on river water quality.Taking the water body in Jialing River of main city zone in Chongqing for an example,test of warm water discharge for river water resources heat pump system is carried out by using physical simulated method.The results indicate that warm water discharge has certain influence on water temperature and water quality nearby water area outfall.warm water discharge leads to water temperature of river nearby water area outfall increasing averagely 3.3℃ under simulated operation condition of river water resources heat pump,and water temperature can effectively restore if the system intermittent operation;warm water discharge leads to dissolved oxygen of local water area outfall decreasing 8%~12%;at the same time,it can accelerate nutrient cycle of the water and raises the permanganate index of water body;warm water discharge is also helpful to transformation the organic nitrogen to ammonia nitrogen in water body and accelerating the nitrogen cycle so as to make the content of ammonia nitrogen and total nitrogen increasing;but the effect is not significant on total phosphorus.
