Abstract: For the monitoring of on-site sewage discharge, COD is usually used as a testing parameter for water quality analysis. COD is chemical oxygen demand, mainly used to measure the content of organic matter in water quality. The measurement results of COD are of universal reference. However, the analysis process of the measurement method takes several hours. Once abnormal data appear in the field, the results cannot be obtained in time to guide the analysis judgment. Combined with the actual production of the device, the device carried out the total alcohol content monitoring and data collection on the main emission anomalies on the basis of the original COD detection and analysis. Because the analysis process of total alcohol content is simple and convenient, the results can be obtained quickly after sampling testing once abnormal increases occur in field emissions. Through the analysis and judgment of auxiliary problems by comparison of results, it is possible to identify the causes and deal with it as soon as possible, reduce environmental hazards, and even avoid the occurrence of environmental anomalies.
