Our country's energy burns coal primarily, to have the nearly hundred million tons pulverized coal ash to discharge massively every year, not only takes the land, moreover causes the very big harm to the Because in the pulverized coal ash adding water pollutant has the strong adsorbability, not only may achieve with the pulverized coal ash processing waste water by governs the waste goal waste, moreover the disposal cost is this article takes the adsorption material with the pulverized coal ash, the methyl orange is an adsorbate, uses the pulverized coal ash to carry on the adsorption to For the better understanding pulverized coal ash's adsorption performance, has carried on the static adsorption experiment and the dynamic adsorption experiment In the static adsorption experiment, through a series of balanced experiments, the use spectrophotometric method track adsorption process density change, under the computation related condition's adsorptive capacity, the definite adsorptive capacity and the pulverized coal ash particle size, the time, the pulverized coal ash throws between the increment, the temperature, the pH value adsorption rule, then appraisal pulverized coal ash adsorption In the dynamic experiment, has carried on the different pulverized coal ash column high the experimental result indicated that in static experiment, above pulverized coal ash to methyl orange adsorption 40 minutes later, the adsorptive capacity increases the change along with the time not to be big, namely 40 minutes later adsorbs achieves balanced basically; Just started the methyl orange to increase to the pulverized coal ash allocated proportion, may make the adsorptive capacity to increase, but in the methyl orange is bigger than 8mg/10g after the pulverized coal ash allocated proportion, the adsorption basically achieves saturated, this explained increases the allocated proportion, its adsorption performance change is not big; In 250C, 280C, 310C, the 340C a series of balanced adsorption experiment sees, along with temperature elevation, the adsorptive capacity has the drop tendency, therefore determined that the optimum temperature is a normal temperature; The solution pH value in 3-11 scopes, is not remarkable to the adsorptive capacity influence, but adsorbs the effect under the neutral condition slightly many; The particle size in 80 items to 140 item of scopes, the adsorption effect obviously rises, after being bigger than 140 items, the adsorption effect increases obviously no longer; In the dynamic experiment, has done the preliminary study to the methyl orange solution in the pulverized coal ash packing column's adsorption, finally indicated the pulverized coal ash packing column tests the effect is friends with in the ordinary conical flask vibrates the
