湖泊重金属污染检测系统的设计

Detection system design of heavy metals pollution in lake

设计了一种湖泊重金属污染检测系统,该系统能够对湖泊中的酸碱度、水质环境以及重金属含量进行实时监控,并根据不同的安全隐患检测项目进行针对性的及时报警,以帮助工作人员及时准确的检测湖泊的污染情况。系统整体结构简单,使用方便,同时能实时反映水环境重金属的浓度,并在超标时主动发出警报。

In this paper, a detection system of heavy metals pollution in lakes was designed, which included PH detection u- nit,water environment detection unit,heavy metals detection unit,CPU,warning unit and wireless communication module.The function of partial unit is as follows：pH detection unit is mainly used for testing water acidity and alkalinity,water envi-ronment detection unit was mainly used in water temperature, dissolved oxygen, and heavy metals detection unit was mainly used for mercury,cadmium,lead and zinc concentration in lakes in real time. The system can monitor the real time pH val-ue ,water quality and heavy metal concentrations in lakes, and can also be targeted timely to alarm according to test items of different security risks. The aim was to detect lake pollution timely and accurately. Moreover,the whole system was simple in structure and easy to use. Mean while, it can reflect the concentration of heavy metals in water environment and give an alarm when it exceeds the standard.
