Development of portable water quality monitoring system using multiwavelength spread spectrum

在本研究中，可以在网站每一瞬间改变水质质量，便携式水质量测量设备由多个带宽传播，使其能够直接测量无过滤的无过滤，开发了非化学饲料样本，以及许多水质量指标的SS， Chl。a、氮氧化物氮、TOC和DOC已对5月在京都市6个站点收集了120个水样本，用于测量散射光强度和荧光强度，以便开始使用散射光强度和荧光强度。1999年11月，对光学强度和水质量指标之间的关系进行了审查。然后，我们从每一个波浪中选择了3个波浪来检测水质量指数。该集中估计的公式是从使用多个回归分析获得的水质量集中中使用光学强度获得的波长度。核实用比瓦湖水域运送（每个月水位0.5米，30米，总共29个样本） ... More ary， 99年，4月，7月，10月订购，以测试这些集中估计的公式的一般性。根据结果，在SS， Chl。a，氮氧化物N，在浓度估计的公式中存在普遍性。这个错误在很大程度上得到了改善，因为这个错误在物体水的协同作用中得到了很大的改善，因为在TOC和DOC中发现了很大的错误，因为被排除的有机物质在水之间也是不同的。24小时固定点在大坝湖泊和河流中进行Coetaneous Monitoring已被运送到订单中，以测试使用该设备实际水域的适用性。这是有可能捕捉大坝湖泊上水位和下水位的变化（0米水深，20米）。因此，需要进一步的改进来进行对细胞从黎明中取出一粒细胞的去除条件的实际应用，等等。在河流中的静态测量，该测量可以稳定24小时，以确定一个恒定的温度在细胞去除条件预防前阶段取出细胞去除条件。而且，这个设备在水质量清晰度上发生了较大的变化，而且它被证明是适用于实际的水区域。Less（低）

In this study, in order to grasp water quality change on a site which changes every moment, portable type water quality measurement equipment by multiwavelength spread spectrum which enables direct measurement of un-filtration, non-chemical feed sample was developed, and many water quality indices of SS, Chl. a, NOx-N, TOC, DOC was measured using scattered light intensity and fluorescence intensity To begin with, 120 water samples were collected in 6 sites in the Kyoto city by May。ォNovember, 1999, and the relationship between optical intensity and each water quality indices concentration was examined. Then, we selected 3 wavelength from the 1 wavelength for each water quality index detection. The concentration estimated formulas which obtained the water quality concentration from optical intensity using this wavelength were obtained by the multiple regression analysis. The verification was carried out using Lake Biwa water (each month water depth 0.5m, 30m, total of 29 samples) in Janu … More ary, 99, April, July, October in order to examine the generality of the these concentration estimated formulas. As the result, in SS, Chl. a, NOx-N, there were the generality in the concentration estimated formulas. The error was greatly improved by deciding the coefficient in the object waters properly, though the error was greatly seen in TOC and DOC, because the dissolved organic substance kind is different between waters. 24 hours fixed point coetaneous monitoring in dam lake and river was carried out in order to examine the applicability to actual water area using this equipment. It was possible to catch the change of water quality in top and bottom (0m water depth, 20m) of the thermocline in the dam lake. However, further improvement was needed for the practical application of dew condensation of the cell from a peep of dawn, etc. In the stationary measurement in the river, the measurement which was stabilized for 24 hours was possible by establishment of a constant temperature oven at front stage for cell dew condensation prevention. And, this equipment had followed large change of water quality sharp, and it was proven to be applicable to the actual water area. Less
