| Abstract: | Polypropylene felt was used in this experiment to adsorb waste oil from the oily wastewater produced in printing and dyeing mill. The maximum adsorption could reach 10 g/g. The effects of static adsorption time, temperature and pH value of wastewater on oil removal efficiency were investigated. The optimum condition was obtained through orthogonal test. Oil removal efficiency could reach 87.12 % in the optimum condition with temperature at 35 ℃, pH at 9, the adding amount of polypropylene felt in wastewater at 7.5 g/L and the adsorption time at 1 h. The dynamic adsorption experimental results indicated that oil removal efficiency was in inverse proportion to water flow rate. |
