奎屯河及瑪納斯河流域平原區(qū)地下水中氮素對(duì)砷遷移富集的影響
[Abstract]:To study the effect of nitrogen on the concentration of As in groundwater in Kuitun and Manas River basins, the migration and enrichment mechanism of high-arsenic groundwater in the study area can be deeply understood. Based on the sampling and testing of 34 groundwater samples from the Kuitun and Manas River basins, the chemical composition of groundwater and the relationship between nitrate, ammonia nitrogen and arsenic concentration in groundwater in the study area were analyzed. The effect of redox environment on arsenic migration and enrichment in groundwater system was also discussed. The results show that the hydrochemical types of high arsenic groundwater in Kuitun River and Manas River basin are mainly SO_4 HCO_3-Na and HCO_3 SO_4-Na type respectively. The groundwater with high arsenic in the study area is located in the reductive environment of low Eh and NO_3~-, high NH_4~ / NT,Fe,Mn, and distributes mainly in the drainage area of the basin and the lake plain at the level. The concentration of arsenic in groundwater samples in Kuitun River Basin was higher than that in Manas River Basin. In the vertical direction, it is mainly concentrated in 80-200 m. There is a negative correlation between arsenic concentration in groundwater and NO_3~- concentration because iron and manganese compounds have not been reduced in the groundwater system indicated by NO_3~- in oxidized environment and therefore the arsenic compounds adsorbed by them have not been released. The concentration of arsenic in groundwater increases with the increase of NH_4~ / NT. NH_4~ / NT can indicate the degree of reduction environment of groundwater system. The larger the NH_4~ / NSCT, the stronger the reduction environment of groundwater system. Arsenic compounds are more likely to cause reductive dissolution and release the adsorbed arsenic into groundwater, and the pentavalent arsenic is reduced to trivalent arsenic.
