Automatic On-line COD Analyzer use multi-syringe of injecting sending System

摘要

The present invention uses potassium bichromate as a driving force for the multi-syringe suction and delivery method of chemical oxygen demand (COD) dissolved in industrial sewage and wastewater treatment plants, sewage treatment plants, or aqueous aqueous samples such as rivers, rivers, and lakes. It is oxidized with aqueous solution and measured in real time with an optical sensor using Visible Rays.The measured electrical signal or data is transmitted to the signal transmission control device. Sends data to general managers in real time to check the abnormal condition of effluents discharged to the water system when discharging, and multi-cylinder to monitor and manage the COD concentration of effluents at a long distance without deploying on-site personnel at low cost. The present invention relates to a COD _Cr continuous automatic measuring device using a suction and a feeding method.;The present invention, such as COD, a representative item for measuring water pollution, is reacted with an aqueous solution of potassium dichromate, which is highly oxidizing, and analyzed in real time using a visible ray absorbance sensor to measure the amount of organic substances discharged into the water system. Tens of thousands of targets can be monitored and managed at the same time by the central control center, and the need for personnel to constantly monitor the site situation can be eliminated, thereby significantly reducing the cost of monitoring pollutants and TMS (Tele-). By supporting monitoring system related integrated management network, it is easy to connect with peripheral equipment and apply on site. In addition, the present invention is a device capable of laboratory scale analysis as well as field application, and it is possible to improve the difficulty of maintaining reproducibility due to the change of water pollution with time of sample water and the error of analytical data according to the experimenter. Measurements can be made continuously and the experiments and manipulations are simple to get fast and accurate analysis data.
