| 中文摘要: |
| 对于我国城市景观水体由于水体特性和外源性污染严重引起的水质不良现象,人们越来越多地采用净化技术开展异位及原位水质修复与保育工作。而在相应的水质净化工程设计与运行中,净化规模的确定依据与方法还有待完善,本研究就景观水体水质修复及保育工程开展净化循环比计算模式的研究。通过对基本处于封闭状态的水体水量及水质内外源污染物的平衡分析,进行了修复与保育两个阶段水质净化循环比数学模式的推演,建立了相应的计算模式与方法,并结合案例进行分析计算。结果表明:水质净化循环比可以作为合理确定工程规模,控制建设投入与运行费用的重要依据。 |
| 英文摘要: |
| As the urban landscape water was polluted by endogenous and exogenous pollution, the ex-situ or in-situ purification technology is being increasingly used in water restoration and conservation engineering. But during the design and operation of the engineering, the method of determining purification scale remains to be perfected. With the balance analysis of water quantity and water quality of relatively closed scenic water, a mathematical model of purification recycle ratio based on water restoration and conservation was established. And the case analysis showed that the purification recycle ratio could be taken as the important basis for getting a reasonable engineering scale and controlling the construction investment and operation cost. |
