第6题：
某河流断面DO和pH的标准指数均大于1，可能存在的状态有()。A:现状DO浓度低于功能区水质标准
B:现状DO浓度高于功能区水质标准
C:现状存在碱污染
D:现状存在酸污染答案：A,C,D解析：根据水质因子标准指数计算公式SDO,j=10-9（DOj/DOs），式中：SDO,j为DO的标准指数；DOj为在j点的溶解氧实测统计代表值；DOs为溶解氧的评价标准限值。当10-9(DOj/DOs)＞1时，解得DOj＜DOs。根据水质因子pH标准指数计算公式：当pHj≤7.0，SpH,j=(7.0-PHj)/(7.0-pHsd)，当pHj＞7.0时，SpH,j=(pHj-7.0)/(pHsu-7.0)。该式中，SpH,j为pH值的标准指数；pHj为pH值得实测统计代表值；pHsd为评价标准中pH值的下限值；pHsu为评价标准中pH值的上限值。当(7.0-pHj)/(7.0-pHsd)＞1时，解得pHj＜pHsd，则存在酸污染；当(pHj-7.0)/(pHsu-7.0)＞1时，解得pHj＞pHsu，则存在碱污染。
