氧化塘自流式回流强化措施的可行性研究 A FEASIBLE STUDY ON INTENSIFICATION MEASURE OF GRAWITY FLOW-RETURN IN OXIDATION POND 张甲耀 1 first-author 夏淑芬 1 陈厚华 1 武汉大学环境科学系 武汉大学环境科学系 用自流式回流代替氧化塘中传统的回流方式,研究了自流式回流氧化塘的处理能力。结果表明,回流塘对污水的处理效果优于无回流塘,其中COD平均去除率提高10%,BOD 5 去除率提高2.59%,溶解氧含量提高1.64mg·L -1 ,异养细菌数降低一个数量级。 The gravity flow-retun was presented to replace the traditional return flow type in oxidation pond and its purification ability was studied. The results indicated that return flow pond was superior to non-return flow pond in was- tewater treatment effect, the average removel ratio raised 10% for COD, 2.59% for BOD respectively, dissolved oxygen raised 1.64mg/L, the amount of hetero- trophic bacteria reduced one order of magnitude. All showed that the intensi- fication measure of gravity flow-return could raise the treatment capacity in oxidation pond and possess actual value of application. 氧化塘 污水处理 回流 oxidation pond wastewater treatment return flow X703 “七五”国家科技攻关资助项目 1992-03-01 2021-04-01 3
