摘　　要：国家标准中重铬酸盐法测定化学需氧量 ,操作时间长 ,占用空间大 ,采用催化快速法测定COD大大缩短了测定时间 ,同时耗能低 ,占用空间小。Dichromate method,the determination of the COD(Chemical Oxygen Demand)takes long time and large space to get the satistory result. To solve these problems, COD determination by catalytic rapid method is used. This method can shorten the time of determination,lower energy consumption and take smaller space. The precision and accuracy of the method can meet the quality control requirement.
