摘要
提出一种采用交流调制双光源技术的污泥浓度传感器方案,采用这种技术可以有效克服自然条件下的干扰并且传感器不用经常清洗,降低了维护成本。基于Lambert-Beer定律从理论上证明了方案正确性和可行性,并设计了一系列实验,从而证明传感器达到了设计要求。
A scheme of activated sludge sensor using dual AC modulation light source is provided. This technique can overcome interferences under nature condition and does not need to clean frequently and lowers the maintenance costs. The feasibility is proved by Lambert-Beer law and also a series of experiments are designed to demonstrate the requirements reached.
