本文根据杭州袁浦—东洲岛地下水中砷的含量和分布特点,研究了砷与pH、铁、硬度、水化学类型和地层岩性的关系,得出了该地区地下中砷含量过高。主要原因是砷本身的水文地球化学性质和它所处的特定水文地球化学环境的影响,属于原生环境污染,而不是现今污染作用造成的结论。相应地提出了降砷处理的力法。
According to the content and distribution of arsenic in the groundwater of Yuanpu-Dongzhou Island in Hangzhou, the relationship between arsenic and pH, iron, hardness, hydrochemical type and lithology of the strata was studied in this paper. It is concluded that the arsenic content in the underground is too high. The main reason is that the hydrogeochemical properties of arsenic itself and the specific hydrogeochemical environment in which it is located belong to the primary pollution of the environment rather than to the current pollution effect. Correspondingly, arsenic reduction method is proposed.
