“生态活水”治水原理与扬州黑臭水体治理

为探索黑臭水体治理的根本途径,在研究自然水体净化功能,分析水体黑臭根本原因和直接原因的基础上,深入阐述了“生态活水”的科学内涵和生态功能,全面揭示了“生态活水”治水的科学原理和技术优势。“生态活水”治水为原位原生态治水,通过水体快速复氧,创建活水微生态系统,并借助微速循环流水的载体作用,实现持续高效净化。扬州黑臭水体治理的实践表明:采用“生态活水”方法治水后3～5 d可以完全消除黑臭,并将黑臭水体转化为“绿水”;15～20 d后水质达国家地表水Ⅲ类水标准。说明“生态活水”治水技术是一种占用资源少、设备投资省、治污速度快、运行成本低、治水效果好、标本兼治的可持续治水技术体系。

Principles of “ecological living water” to purify sewage and its application in black and smelly water treatment of Yangzhou

To explore the fundamental way of black and odorous water treatment, based on the study of the purification function of natural water body and the analysis of root cause and direct cause of black and odorous water body, we elaborated the scientific connotation and ecological function of “ecological living water”, and fully revealed the scientific principle and technical advantages of “ecological living water” for sewage treatment. “Ecological living water” was the original ecological water control in situ. Through the rapid water reaeration, the micro-ecosystem of living water was created. Meanwhile, with the support of micro-speed circulating water, the continuous and efficient purification was realized. The practice of black and odorous water treatment in Yangzhou showed that, 3-5 days after the treatment of “ecological living water”, the black and odorous water was completely eliminated and transformed into “green water”. 15-20 days after the treatment, water quality reached the national surface water class Ⅲ water standard. Therefore, “ecological living water” may be a kind of sustainable water control technology system with investment of less resources and equipment, fast pollution control speed, low operation cost, good water control effect and both symptoms and treatment.
