污染河流治理与修复技术现状及展望

Present situation and prospect for treatment and repairing technology of polluted river

对河流治理与修复技术进行了综述,将其归纳为物理、化学、生物修复技术三大类:物理技术包括人工曝气、引水冲污、底泥疏浚;化学技术包括化学除藻、重金属固定;生物修复技术包括微生物强化、植物强化、生物膜法。对每种技术的研究现状进行了简介和评价,并展望了这三类技术今后的发展方向。

In this paper the treatment and repairing technology of polluted fiver was summarized, which were physical, chemical and bioremediation technologies; physical techniques include artificial aeration, polluted watercourse flushing, sediment dredging; chemical techniques include chemical alga- killing, heavy- metal fixer; bioremediation techniques include microorganism str- engthen, plant strengthening, biofihn process. These techniques are briefly included and evaluated. The future developments of these technologies are prospected.
