The result demonstrated that, because of high organic load, metabolism of aerobic-microorganism and aerobic decomposition of organics being extremely vigorous, DO was not enough mostly in all ponds and ’OXYGEN BE IN DEBT’ phenomenon happened sometimes in cold climate. But the degree of DO and prelimnary productivity displayed raising tendency from pond No. 1 to No. 5, it showed that the water quality was improved in certain extent. 复合氧化塘 溶解氧 初级生产力 complex oxidation pond DO Preliminary productivity X524 1993-02-01 2021-04-01 2
