【摘要】：針對(duì)壓力延遲滲透(PRO)過程中正滲透膜片的性能表現(xiàn),采用無隔網(wǎng)、單隔網(wǎng)和雙隔網(wǎng)相互對(duì)照的方法考察了過程中正滲透膜片的水通量和鹽通量的變化情況。結(jié)果發(fā)現(xiàn),實(shí)驗(yàn)過程中無隔網(wǎng)時(shí)濃差極化現(xiàn)象對(duì)水通量的影響比較明顯;單隔網(wǎng)能有效減弱濃差極化現(xiàn)象,水通量平均提升10%左右,鹽通量下降幅度為3.4%左右;雙隔網(wǎng)雖然在一定程度上可以減弱濃差極化現(xiàn)象,但實(shí)驗(yàn)過程中出現(xiàn)的陰影效應(yīng),導(dǎo)致膜片有效滲透面積減少及水通量快速下降。經(jīng)過比較發(fā)現(xiàn)PRO過程中在膜片兩側(cè)添加單隔網(wǎng)可以使膜的水滲透性能和鹽截留性能達(dá)到較好的狀態(tài)。
[Abstract]:In view of the performance of the positive permeable diaphragm in the process of pressure delayed penetration (PRO), the change of water flux and salt flux in the positive permeable diaphragm during the process was investigated by the method of non septum, single screen and double isolation. The network can effectively reduce the concentration polarization, the water flux increases by about 10% and the salt flux decreases by about 3.4%. Although the double isolation network can weaken the concentration polarization in some degree, the shadow effect in the experimental process leads to the decrease of the effective permeable area and the rapid decrease of the water flux. The PRO process has been found in the process of comparison. Adding single spacer on both sides of the diaphragm can make the membrane's water permeability and salt rejection better.
