【摘要】 目的了解农村饮水卫生质量和水井结构对水质量影响情况。方法选择无锡某一自然村老水井和用浅式漏斗替代老井旁窨阱及阴沟的新井,作2种井水水质的比较。结果水井改进后水质指标硝酸盐氮、氯化物、粪大肠菌群平均值明显好转,耗氧量、氨氮、亚硝酸盐氮平均值有好转。结论水井结构改进后水质卫生质量有明显提高。更多还原

【Abstract】 [Objective]To know the status of the drinking water quality and the effect of well structure on the water quality in countryside.[Methods]Make a comparison between the water quality of some old wells and improved wells covered with shallow funnel in the same natural village.[Results]Compared with the old wells,the water quality of improved wells was better,which expressed that the average value of nitrate nitrogen,chloride and fecal coliform group were significantly improved,and average value of chemical oxygen demand,ammonia nitrogen,nitrite nitrogen also had taking a turn for the better.[Conclusion]After rebuilding the well structure,the water quality were improved remarkably.更多还原
