Abstract

Excessive amount of nutrients content such as phosphorus could pollute the river (e.g., organic pollution) and harm the ecosystem, in long term, to eutrophication. Hence, it is essential to monitor and control the concentration of NPK (Nitrogen, Phosphorous, K for Potassium or Potash) elements for sustaining good water quality and reducing water pollution of natural water. Hence, the main idea of this research is to develop an integrated optical sensor to quantify the concentration of phosphorus to reduce river pollution. Design of the optical sensor comprises of LED at specific wavelength for the transmission system and LDR as detection system together with the associated circuitry and power systems and signal analysis is done at the microcontroller. System performance has been very good and is validated against standard lab measurements.
河流磷污染感官检测与定量系统
磷等营养物含量超标会造成河流污染(如有机污染),损害生态系统,长期造成富营养化。因此,监测和控制NPK(氮、磷、钾或钾)元素的浓度对于维持良好的水质和减少天然水的水污染至关重要。因此,本研究的主要思路是开发一种集成光学传感器来量化磷的浓度,以减少河流污染。光传感器的设计包括特定波长的LED作为传输系统,LDR作为检测系统,以及相关的电路和电源系统,并在微控制器上进行信号分析。系统性能非常好,并通过标准实验室测量验证。
