Study On The Use Of Potassium Permanganate In Combination With Damp Powered Activated Carbon For The Removal Of Odor

The water quality of the lakes and reservoirs is getting to worse ,the algae increase. Algae could produce Geosmin(GSM) and 2-Methylisoborneol,the last ones lead to odor.Odor in drinking water makes people uncomfortable,resulting in distrust to water quality. This text studied on the use of potassium permanganate in combination with damp powered activated carbon for the removal of Odor,the result incicated that Odor can be controlled effectively.This text discussed the reason of causing Odor ,the mechanism of odor made by algae and analysed the varieties of Odor ,offered advanced measure to controlled Odor.This text set up the method which can examine the conten of GSM and MIB in the water,made sure that algae is the mostly matter which can cause odor.The experimental results with brake showed that the best way of the use about potassium permanganate in combination with damp powered activated carbon is to apply the PAC in Reservoir under the dose of 20mg/L and the KmnO4 before coagulation under the dose of 0.5 mg/L.The experimental results in manufacture showed that conventional treatment processes has few effect on the removal of odor,nor has the chlorin. Odor can be controlled effectively with increasing KmnO4 if TON of the raw water is low,the removal of odor is above 80%.Compared with those technics above, it has the best effect on the removal of odor by potassium permanganate in combination with damp powered activated carbon,the removal of algae is 84.87%,the removal of MIB is 100%,the removal of TON is 90.63%.The damp powered activated carbon has few pollution in manufacture.
