【摘要】 文章建立了一种准确、有效、适用于远程监控的新型水质综合指数(WQCI)评价方法。该方法是基于可采用电化学传感器测量的水质五参数指标:温度(T)、溶解氧(DO)、氧化还原电位(ORP)、电导率(K)、酸碱度(p H),结合数学统计K-star模型以《地表水环境质量标准》(GB-3838-2002)为参照标准,通过K-star模型的分类和运算得出未知水体水质类别。同时还对此水质综合指数(WQCI)评价方法进行了一系列的优化实验,并将检测结果与环保局发布数据做了比较分析,发现结果基本一致。与其它的水质综合评价方法相比,该方法能够实现检测参数所用仪器的一体化,便于现场和远程自动监控分析。若与网络技术结合起来,则可实现水质实时、在线监测。更多还原

【Abstract】 A new type of water quality comprehensive index evaluation method(WQCI) which could be applied to the remote monitoring of water quality with its accuracy and effectiveness was established. The method is based on the electro-chemical sensor measuring five water quality parameters, namely temperature(T), dissolved oxygen(DO), oxidation reduction potential(ORP), electrical conductivity(K) and p H. Combined with the K-star model of the mathematical model and the sur-face water environment quality standard(GB-3838-2002) as reference, the unknown water quality category is obtained by classification and calculation of K-star model.At the same time, the water quality comprehensive index(WQCI) evaluation method was optimized by a series of experiments. By comparing the results of the experiments with the statistics released by the environmental protection agency,we find the results are basically consistent.Compared with other water quality compre-hensive evaluation method, this method can realize the integration of the testing instruments which is used to detect the pa-rameters. It is easy for the on-site and remote automatic analysis.If combined with network technology, it can realize the realtime,on-line monitoring of water quality.更多还原
