基于嵌入式的污水多参数监测系统研究与设计 The Design andl pollution has become one of the important issues in today's society. Water pollution is an important component of environmental pollution, the state and local governments have attached great importance to the reasonable discharge of sewage and comprehensive treatment. Monitoring of chemical oxygen demand of sewage is an important indicator of sewage, and therefore achieve chemical oxygen demand of sewage line monitoring is in the market,there a lot of monitoring equipment to get the chemical oxygen demand of sewage. but most of the instruments with little high precision monitoring, measurement takes a long time, can not achieved online surveillance and secondary the monitoring of foreign equipment do a lot of improvement on the accuracy,the monitroring time and the seconday pollution, foreign equipment is expensive, not suitable for popularization and promotion in our project use the new principle-the electrochemical theory to measure the chemical oxygen demand of only to solve the long time monitoring time probleom and the secondary pollution problem, and equipment manufacturing costs are lower, but also with intelligent network ,the advantages of miniaturization, is a more ideal instrument for monitoring chemical oxygen demand of sewage.
In this project,we completed the choice of the principles of the wastewater chemical oxygen demand ot the monitoring,the hardware design of the monitoring equipment,the software design,and in the end of the paper presented the instrument to further improve the method.
During the choice of the principle of the monitoring, due to the traditional principles of wastewater COD measurements need a long time to monitor, unable to meet the online requirements of measurement and the real-time measurement, the monitoring of chemical oxygen demand of the tr
