生物-生态修复技术在景观污染水体治理中的应用

采用生物治理与生态修复技术对昆山市环城北路景观池塘水体因富营养化、流动性差等引起的黑臭现象进行治理。治理后TN、TP的去除率均超过85%,水质达国家地表水Ⅲ类水标准,水体透明度达1.28 m,生物多样性增加,景观效果显著改善。结果表明,生物-生态修复技术对没有或仅有少量污水排入的受污染景观水体较为适宜。

Application of bio-ecological restoration techniques to treatment of polluted landscape water

The polluted water of a landscape pond located in North Huancheng Road in Kunshan City was treated using bioremediation and ecological restoration techniques, in order to abate the malodorous odor caused by eutrophication and poor mobility of water. After the treatment, the removal rates of TN and TP exceeded 85 %, the water quality met the Class III national standard of surface water, and the water transparency level reached 1.28 m. Accordingly, there has been an increase in biodiversity, and the landscape effect has significantly improved. The results show that the techniques are practicable for polluted landscape waters with a small amount of sewage or without sewage.
