上海市位于东海之滨,水源每年受海水入侵影响,本文收集、分析了近十年源水氯化物、硫酸盐、总硬度、溶解性总固体浓度的资料,对两个含氯化物不同浓度的地区作人群味觉和流行病学调查,又对青少年和职工进行了味觉测试,建议以Cl~-400mg/L、SO_4~=250mg/L、TH450mg/L、TDS1200mg/L作为海水入侵期的最大容许浓度,作为上海市长江引水取水点的选址和蓄水库容量设计的依据。
Shanghai is located on the coast of the East China Sea. The water source is affected by seawater intrusion each year. In this paper, we collected and analyzed the data of chloride, sulfate, total hardness and total dissolved solids in the source water over the past decade. In order to test the taste and epidemiology of the population, we also tested the taste of teenagers and workers. It is suggested that Cl ~ -400mg / L, SO_4 ~ = 250mg / L, TH450mg / L and TDS1200mg / L be the maximum allowable seawater intrusion Concentration, as the Shanghai Yangtze River water intake and drainage points site selection and storage capacity design basis.
