溶解氧测量
应用背景溶解氧的含量与水温、氧分压、盐度、水深深度、水生生物的活动和耗氧有机物浓度有关。
水中溶解氧含量受到两种作用的影响:一种是使DO下降的耗氧作用,包括好氧有机物降解的耗氧,生物呼吸耗氧;另一种是使DO增加的复氧作用,主要有空气中氧的溶解,水生植物的光合作用等。这两种作用的相互消长,使水中溶解氧含量呈现出时空变化。
在自然条件下,水在流动时,复氧过程比较迅速,较易补充水中氧的消耗,使水体中溶解氧保持一定的水平,反之,在静水条件下,复氧过程缓慢,水中含氧得不到及时补充,处于嫌气状态。关键技术水被有机物污染后,由于好氧菌作用使其氧化,消耗掉溶解氧。如果得不到空气中氧的及时补充,那么水的溶解氧就减少,最终导致水体变质,溶解氧越少,表明污染程度越严重。溶解氧在评价标准中作为水体感官指标及保护水生生物生存指标。
