生活污水处理中COD监测条件的控制

Conditional Control in Monitoring and Analysis for the Chemical Oxygen Demand of Sewage

生活污水中因有大量粒、块状的悬浮物,悬浮物分散的均匀性很差,也是造成此类废水耗氧的重要因素。生活污水最关键的控制因素是样品的代表性,忽略了影响水质代表性的任何一个环节,都将造成测定错误并影响最终处理效果。

Sewage with a large number of tablets, the massive suspended solids, suspended solids dispersed poor uniformity, it is also such an important factor in waste water consumption, the most critical factor of Sewage control is representative of the sample, if ignoring any segment that impact on the representation of quality of water, result in the wrong conclusions to determinate through the analysis.
