摘要：考察了上海市几条中小河流的水质特征及生物膜对漕河泾和青春河水的净化效果,对污染河流修复方法作了讨论。结果表明,单靠生化方法难以达到修复中小河流的目的,可采用先生化后混凝或先混凝后生化的方法对其进行修复。
The water quality characteristics of Beixinjing,Caohejing,Zhangjiatang and Qingchunhe rivers across Shanghai Municipality were investigated.The purification efficiencies of the river water of Caohejing and Qingchunhe by biofilms apparatus were also inspected.The remediation method for polluted river water was discussed. The results showed that DO values of the four rivers are all less than 3 mg/L,CODcr values ranged from 26.19mg/L to 36.98 mg/L, BOD5 values ranged from 3.63mg/L to 18.70 mg/L,the content of nitrogen-ammonia and total phosphorous are all 5～10 times of the value stipulated by national standard for surface water quality(GB).The water quality of the four rivers conforms to IV or V grade standard of surface water.The biofilms apparatus cannot effectively remove CODcr in Qingchunhe river water,but the nitrogen-ammonia can be effectively removed.The maximum removal rate of nitrogen-ammonia is 80%.The removal rate of CODcr in river water of Caohejing by the biofilms apparatus is more than 40%,and the removal rate of NH3-N is relatively low.The results showed that only biological method can not reach the goal for remediating the polluted rivers. The river water should be restored by the method of 'biodegradation+ flocculation' or 'flocculation+ biodegradation'.
