Cod Measurement Methods And Rapid Monitoring System

In view of the environmental conservation managements' request that COD should be measured in the lump, we put forward the design "the on-line fast automated monitoring system based on internet for COD " and the COD measurement' s property right belongs to us. The system is designed in a block structure that is made up of three parts: monitor instruments in the worksite, transmission through networks and a host computer.Compared with the traditional instruments for COD, the system cuts down a second time pollution and long heating time. The system can demarcate, measure and clean automatically. Long time measurement is easy to be satisfied. It gives out optic alarm when bearing dangerous status, processes and stores history data that are out of the range of permission, and sends them to the host computer automatically. The system meets the need of instrument development: smaller, blocked, intellectualized, network connected. So the system is worth disseminating.This article mainly introduces: The necessity of developing fast monitoring system for COD and the system' s gross characters The means for measuring COD and the development trends of instruments. The realization of this system. Difficulties of this system Result and prospect...
