河道水体污染治理与修复技术研究进展

The Technology Progress for Treatment and Repairing of Polluted River Water

通过对河道水体污染治理与修复技术进行综述,归纳总结了物理、化学、生物-生态3种修复技术的原理、工艺核心及适用范围等技术研究进展,其中物理技术包括截污分流与引水冲污、底泥疏浚、曝气复氧,化学治理技术包括化学除藻、化学固定,生物-生态修复技术包括微生物强化、植物净化、人工湿地、生物膜净化及组合生物-生态修复技术。同时,提出了河道水体修复涉及学科多,应该根据河道的实际情况,采用合理的治理和修复技术。最后对河道水体污染治理与修复技术进行了展望。

Through reviewing pollution treatment and repairing technology of sewage river, the research advances about principle, process core and application scope of physical, chemical, biological repairing technologies were summarized, the physical technology including sewage intercep- tion and diversion, sediment dredging, aeration, the chemical technology including chemical removal of algae, chemical fixation, the biological res-toration technology containing microbial enhancement, plant purification, constructed wetland, biological membrane purification and combined bio- logical restoration technology. Meanwhile,due to river water restoration involved many disciplines, appropriate repairing technology should be adopted based on the actual situation. Finally ,pollution treatment and repairing technology of sewage river was forecasted.
