Abstract

地表水水质浊度检测方法,采用散射法图像传感器线阵作为光敏元件,当一定波长的光束照射到被测水样时,浊度水样中的颗粒物质使光产生折射,散射光强度与水样浊度成正比的特性测定水质浊度,所述图像传感器线阵是指至少五个光敏二极管组成,所述光敏二极管是硅衬片表面蒸镀二氧化硅层,在硅衬片和电极加偏置电压。本发明方法散射光的强度大、灵敏度高,同时因散射式浊度仪相较而言能够消除水体色度产生的影响,可以应用于许多常规检测受限的环境水体。

Description

地表水水质浊度检测方法
技术领域
本发明涉及水体检测技术领域,特别涉及地表水水质浊度检测方法。
背景技术
浊度是水的透明程度的量度,是由微小颗粒,如淤泥,粘土,浮游生物及其它微生物和有机物等引起的,其表征了水中悬浮物对光线透过时所发生的阻碍程度。目前广泛将浑浊度作为水净化效果好坏的标志。自来水厂的出厂水浑浊度直接展现源水净化工程的效果,出厂水末梢水的浑浊度表示供水与配水设施是否正常,是衡量水质优劣的重要指标之一。水中的无机物泥砂不一定直接有害健康,但它们能吸附细菌和病毒,是一种潜在的不安全因素。因此实现饮用水浊度的高准确度及实时测量对人健康具有重大的实际应用意义。
尽管悬浮固体会产生浊度,测定浊度和测定悬浮固体是不同的。测定悬浮固体测的是样品中固体的重量,而浊度测定结果反映出悬浮固体散射光的程度,许多样品的单位悬浮固体含量与浊度值之间也并无线性关系。这可能是由颜色、颗粒物形状、分布和对光线的吸收等干扰因素造成的。
发明内容
本发明的针对折射光法测浊度存在干扰性,提供地表水水质浊度检测方法,其特征在于,采用散射法图像传感器线阵作为光敏元件,当一定波长的光束照射到被测水样时,浊度水样中的颗粒物质使光产生折射,散射光强度与水样浊度成正比的特性测定水质浊度,所述图像传感器线阵是指至少五个光敏二极管组成,所述光敏二极管是硅衬片表面蒸镀二氧化硅层,在硅衬片和电极加偏置电压。
所述方法采用90度方向的散射法来测量水质的浊度。
所述的二氧化硅层厚度为600A-800A。
所述光敏二极管排列排列,以四相工作方式把相应的电极并连在一起,并在每组电极上加上一定时序的驱动脉冲。
本发明方法散射光的强度大、灵敏度高,同时因散射式浊度仪相较而言能够消除水体色度产生的影响,可以应用于许多常规检测受限的环境水体。
具体实施方式
下述非限制性实施例可以使本领域的普通技术人员更全面地理解本发明,但不以任何方式限制本发明。
