关于COD预制试剂测定煤直接液化废水的二次使用探究
  

为降低煤直接液化废水COD项目检测和COD废液处理的高成本,同时提高高量程COD试剂的利用率,针对高COD废水进行了专门实验分析。在试剂的量程允许的范围内,同一水样,连续重复使用一支试剂俩次,发现两次测定结果虽不相同,呈递减趋势,但是减小的趋势成一定的规律性,第二次的测定结果是第一次测定结果的90.31%~91.82%。所以,在仪器误差和方法误差允许的范围内,第二次的测定结果就变的有据可循。

Abstract In order to reduce the high cost of COD project detection and COD waste treatment of coal direct liquefied wastewater, and improve the utilization rate of high-range COD reagents, a special experimental analysis was carried out for high-COD wastewater. Within the allowable range of the reagent, the same water sample, reuse a reagent twice in a row, and find that although the two measurement results are different, there is a decreasing trend, but the decreasing trend is a certain regularity, and the second measurement result is 90.31%~91.82% of the first measurement result. Therefore, within the scope of instrument error and method error, the results of the second measurement become well-documented.
