河北某河段水体应急治理实例

An Example on Eemergency Treatment of A Water Body in A Section of A River in Hebei Province

针对河道污染特点,利用应急药剂多点投加并配合人工增氧措施和微生物活化装置,在治理河道进行三段强化治理。治理前,通过采集河道水样,选取PAC、COD去除剂和氨氮去除剂三种应急药剂进行试验,结果表明三种药剂最佳投加量分别为40 mg/L、600 mg/L、300 mg/L。经过10天应急治理,河道水质明显改善,水质指标达到《大清河流域水污染物排放标准》中重点控制区排放限值,运行费用约为0.57元/(m^( 3)·d),具有良好的经济效益。

In view of the characteristics of river pollution,emergency agents were mainly used to add and cooperate with artificial oxygenation measures and microbial activation devices to strengthen the treatment of three sections of the river.Before treatment,by collecting river water samples,three emergency agents of PAC,COD remover and ammonia nitrogen remover were selected for testing,and the optimal dosage of the three agents was determined to be 40 mg/L,600 mg/L and 300 mg/L,respectively.After 10 days of emergency treatment,the water body of the river was improved significantly,and the water quality reached the discharge limits of the key control areas in the Daqing River Basin Water Pollutant Discharge Standards.The operating cost was about 0.57 yuan/(m^(3) ·d),which had good economic benefits.
