摘　　要：介绍了水浊度常用的两种测量方法散射法和透射法的原理、特点及其适用范围。结合散射法、透射法特点,提出一种适用于大范围变化浊度测量的综合式探测方法—比值法,并采用了基于比值法的天健TTS浊度计,以及自制的实验平台对福尔玛荆标准液进行测量。列出了TTS浊度计和自制实验平台的测量数据,同时推导了自制实验平台数据处理的公式,并计算出使用不同方法的浊度值。对实验结果的分析和比较表明比值法能有效提高水浊度的测量精度,扩大水浊度的量程。Two kinds of common measuring methods of water turbidity, scattering method and transmission method are introduced-from principles, characteristics and application situations. Then a synthesis detection method-ratio method, suitable for measurement of water turbidity changing in a large range is put forward based on characteristics of scattering and transmission method. Tenging TTS turbidimeter on the basis of ratio method and self-made experiment platform are used to measure the turbidity of Formazine standard solution of different turbidity values. The measured data of Tenging TTS turbidimeter and the self-made experiment platform are listed, the data-processing formulas are deduced and the turbidity values with different methods are calculated. Results indicate that with the ratio method, the measurement accuracy of water turbidity can be improved effectively and measurement range is also extended.
