Method for evaluating effect of adsorbing CODMn (Chemical Oxygen Demand) by powdered activated carbon in raw drinking water

The invention discloses a method for evaluating the effect of adsorbing CODMn by powdered activated carbon in raw drinking water, and the evaluation method comprises a method for stopping a test of the removal effect of adsorbing CODMn by powdered activated carbon in raw drinking water and a method for calculating the removal rate of CODMn, and the removal effect in a specific adding mode is evaluated by calculating the removal rate of CODMn before and after the powdered activated carbon is added. According to the method, the current situation that domestic and overseas carbon-containing water detection methods are diverse and uneven in form is relieved, and the stability and comparability of similar experimental data of different teams and different water areas are greatly improved. The device and the filter membrane material adopted by the invention are convenient to purchase in the market, the pretreatment technology is simple and controllable, and the device and the filter membrane material are easily pop
