- 摘要：介绍了一种全新的光电检测方法---透光脉动检测技术。它利用悬浮液颗粒组成的随机脉动变化特性,可以分析和检测出悬浮液中颗粒的聚集状态及其变化情况。将该检测技术用于水处理中的絮凝过程的研究,便成为一种非常有效的方法和手段,可适用于高浊度水、低浊度水、工业废水和污泥脱水等多种水质的絮凝过程及其影响因素的研究中,具有广泛的应用前景。这种检测技术可进行流过式连续在线检测,不需要进行清洗和标定,可达到完全免维护的程度,为絮凝过程的研究提供了一种非常独特的方法。
- Abstract：A new photoelectric monitoring method,the monitoring technique of fluctuation of transmittedlight,is introduced. It is based on the characteristic of random variations in composition of the suspended particles. The aggregating state and its detailed flocculating procedure of particles in suspensions can be analyzed and monitored continuously. It can be used to study the flocculation processes and their influence factors in the water treatment field,such as high turbidity or low turbidity water,industrial wastewater and sludge dewatering. The on line monitor operates continuously in a flow through mode and shows the complete processes of flocculation in considerable detail. Especially,the output of the monitor remains unaffected by fouling of optical surfaces or electronic drift of electrical elements. There is no need to clean up the sampling tube or calibrate the output during the operation.
