交叉缩放管内生物污垢热阻与水质参数的关联分析

Correlation Analysis of Microbe Fouling Resistance and Water Quality Parameters in the Alternating Elliptical Axis Tube

为了研究电厂循环水中的水质参数对铁细菌生物污垢热阻的影响,以交叉缩放椭圆换热管为对象,研究铁细菌生物在其内部的污垢特性。采用灰色关联分析了水质参数对污垢热阻的影响。结果表明:各水质参数中权重最大为COD,最小为亚铁离子含量。流动工质的p H值、电导率随铁细菌污垢的热阻先升高后趋于平缓;而亚铁离子含量、COD和DO含量随铁细菌污垢的热阻逐渐下降。

For researching the effect of the water quality parameters in recycled water on iron bacteria microbe fouling resistance,taking the alternating elliptical axis tube as the experimental subject,the lab analyzes the characteristics of iron bacteria microbe by the way of grey correlation analysis on the water quality parameters effecting on fouling resistance. The results indicate that the maximum weight is COD,and the minimum is ferrous ion content. With the fouling resistance fluctuation,the p H value and electrical conductivity are increased at first and steady later on,but the ferrous ion concentration,COD and DO are declined.
