北京化工研究院和浦口电器仪表厂联合研制的TOD—1型总耗氧量测定仪于八二年九月下旬在南京通过部级技术鉴定。总耗氧量(TOD)是指污水中的污染物质在高温催化氧化时所消耗掉的氧量,是一种评定水质污染程度的综合性指标。TOD—1型测定仪包括气路单元、控制单元和纪录仪三部分。气路单元主要由电化学氧泵(此为国内首先制成)、高温氧化炉、氧化锆氧量检
Beijing Institute of Chemical Technology and Pukou Electric Instrument Factory jointly developed by the TOD-1 total oxygen meter in late August 1982 in Nanjing through ministerial technical appraisal. Total Oxygen Demand (TOD) refers to the amount of oxygen consumed by pollutants in sewage when they are oxidized at high temperature. It is a comprehensive index to evaluate the degree of water pollution. TOD-1-type analyzer, including gas unit, control unit and recorder three parts. Gas unit is mainly composed of electrochemical oxygen pump (which is the first made in China), high temperature oxidation furnace, zirconia oxygen detection
