摘要
测量污水排海稀释扩散模型试验中污水浊度,目的是研究和计算污水在水体中的稀释度.光纤反射型传感器正是这种试验中测量浊度的好方法.对传感器结构、测量原理以及响应特性进行了分析和研究.其不仅能单线测量,而且通过计算机数据采集可以实现多路实时在线测量.试验表明,此方法具有灵敏度高、响应速度快、抗干扰能力强、操作简单、适用于远距离多路检测等优点;其传感器具有体积小、机械强度大、制作成本低等特点.
The objective to measure the sewage turbidity when dilution diffusion model of sewage is tested for discharging sewage into the sea is to research and calculate the dilution rate of the sewage in the water. The fiber reflective-type sensor is a good tool during the test. The configuration, measurement mechanism and response characteristic of the sensor are analyzed and investigated in this paper. Using the sensor not only single-line measurement can be realized, but also multi-line and real-time measurements can be realized by data collected with computer. It＇s showed that this method has many advantages, such as high sensitivity, quick response speed, strong anti-interference capability, simple operation. The sensor is characteristic of small dimension, high mechanical robustness and low manu- facturing cost.
