综合治理技术在沈阳南运河污染防治中的研究应用

针对沈阳市南运河富营养化、黑臭、水草疯长等现象,确定了以其中的彩塔湖河段为示范区,以其上游青年公园和其下游河段为技术推广区的污染治理范围,制定了以复氧技术、药剂技术和水生植物技术相结合的综合整治方案.经过1年的研究实践,目前南运河水质明显改善,水体富营养化、黑臭及水草疯长被有效控制,治理区域水环境质量明显好转,取得了较好的社会效益和环境效益.

The Study and Application of Integrated Pollution Control Technology in South Canal in Shenyang

Aim at eliminating the nutrient-enriched, black and odorous phenomena and rapid growth of aquatic plants in south canal in Shenyang, we selected Cai-ta Lake as the demonstration cite of pollution control and prevention, area, and selected Youth park at the upwards of south canal and downwards area as the technology extent area, we established the aeration skill, medicament and aquatic plant absorbing technology as the main integrated technology. After one year contro ling and prevention, the water quality of south canal was improved obviously, and the rapid growth of aquatic plants and the black water and bad smell was controlled effectively, all water area of south canal is in fine circle and in self-purification state, and better effect has been gotten in social and environmental benefit respectively.
