笔者在工作中实测到北京局部地区浅层地下水温明显增高和水质恶化的数据,从而提出应注意浅层地下水热污染问题。据不完全统计,北京受污染的河渠段已长达500公里,占河段总长70%。特别是高井电厂和石景山电站等冷却废热水(30～37℃)的排放,使永定河引水渠的水温常年高于原天然水温6～10℃。这个数据,已超过了国际上承认的防止地表水受热污染的标准。苏联规定,饮用水和作物栽培用水的水体,接收废热之后的水温,不应超过夏季天
The author measured the data of shallow groundwater temperature and water quality deterioration in some areas of Beijing in the work, and put forward that we should pay attention to the shallow groundwater heat pollution problem. According to incomplete statistics, Beijing’s polluted river channel has reached 500 kilometers, accounting for 70% of the total length of the river. In particular, discharge of cooling waste hot water (30-37 ° C) such as Gaojing Power Plant and Shijingshan Power Plant will make the water temperature of Yongding River diversion canal year-round higher than the original natural water temperature by 6-10 ° C. This figure has exceeded the internationally recognized standard for preventing thermal pollution of surface water. The Soviet Union stipulates that the body of drinking water and crop cultivation of water, water temperature after receiving waste heat, should not exceed the summer days
