摘　　要：近年来,无机陶瓷膜因其良好的稳定性而在矿井废水的净化再利用中得到了广泛的应用.为了了解陶瓷膜的通水量与过滤时间、过滤压力以及膜孔径的关系,通过对新化县联合煤矿矿井废水经特定通水量测定装置多次实验的基础上,得出以下结论:陶瓷膜的过滤通量随着压力和孔径的增大而增大,但随着过滤的进行杂质颗粒逐渐累积导致膜孔堵塞,膜的孔隙率下降导致其阻力增大,通水量降低,当滤饼层形成后,阻力逐渐趋于稳定,通水量保持在一定的范围.In recent years,the inorganic ceramic membrane has been widely used in the purification and reuse of wastewater under the mine because of its good stability. In order to understand the relation between the water content of ceramic membrane and the filtration time,and filtration pressure and membrane pore size,the conclusions are drawn on the basis of many experiments of the coal mine waste water in Xinhua County through a certain water flow measuring device. The filtration flux of ceramic membrane increases with the increase of pressure and pore size,but with the filtration,the accumulation of impurity particles leads to the plugging of membrane pore,and the porosity of membrane decreases,which leads to the increase of resistance and the decrease of water flow. When the cake layer is formed,the resistance tends to be stable,and the water flow is kept in a certain range.
