Abstract:

The complex dynamic membrane formed of the complex material, which consists of nano molecular sieve and diatomite cross -linked with polymer under dynamic state has been studied. Membrane forming test, the determination of inlet flow and membrane lasting time and the removal result of phosphate from wastewater have been carried on in the reactive process. The formation of dynamic membranes at different flocculant doses and different flow rate and their effects on the removal of phosphate from wastewater, and the existing time of the membranes have been tested. The results show that under certain conditions the complex material can form stable membranes and remove the phosphate fromthe wastewater. It provides industries with referential data.

Key words: nano molecular sieve, diatomite, dephosphorization

摘要：

研究了纳米分子筛与硅藻土组成的复合材料与聚合物交联形成的复合动态膜层，测试了不同絮凝剂用量和不同流速下动态膜层的形成状况以及对废水中PO₄^3-的去除效果。实验结果表明，复合材料在一定的条件下，能够形成稳定的膜层并能很好的去除废水中的PO₄^3-。为该复合材料在实际生产中应用提供了参考。
