摘　　要：采用曝气复氧、投加高效微生物菌剂及生物促生液、放养水生植物等构建的组合生物修复技术,对苏州河严重污染支流——绥宁河进行原位污染治理和生态恢复工程试验。结果表明,严重污染的水体消除了黑臭,水体COD平均下降50％以上,DO平均升高2mg/L左右、透明度平均增加10cm以上;单一工程措施的修复效果不及组合技术。试验期间,主要微生物指标以及底泥有机质含量未发生显著变化,说明河流生态的彻底恢复还有待时日。In situ bioremediation of seriously polluted Sui-ning Creek has been conducted for almost two months. It was concluded that average CODCr of waterbody decreased by more than 50%, average clarity increased from 17cm to 28cm and average DO from 0.4mg/L to 2.7mg/L. Combined bioremediation technology was more advantageous than single ones. Microbial parameters such as quantities of heterobacteria, E.coli and desulfate bacteria both in water and settling sludge underwent slight changes.
