摘要
若水体有机物污染严重、水中溶解氧低于4mg/L,藻类将大量繁殖,导致鱼类死亡、黑臭水体及水华现象,因此水中三氧监测是地表水或污水的必测项目,研究水中三氧对水源自净作用有重要意义。本文基于长江荆江河段水质监测成果资料,探讨了三峡水库蓄水前后荆江河段水体三氧变化情况,表明长江荆江河段随着清水下泄,水中悬浮物含量降低,有机物污染减小,水体水质得到一定改善。
If the organic matter pollution is serious,the dissolved oxygen in the water is lower than 4mg/L,the algae will multiply,which will lead to the death of fish,the black smelly water and the water bloom.Therefore,monitoring of three oxygen in water is surface water or sewage project will be measured,three oxygen in water has important significance for water self purification.According to the Jingjiang reach of the Changjiang River quality monitoring data,It discusses the changes of Jingjiang River water three oxygen before and after impoundment of Three Gorges reservoir.and shows that the Jingjiang River with water discharging,reduce the suspended solids content in water,organic pollution reduction,water quality has been improved.
