Abstract：

The powder activated carbon-diatomite biologically enhanced dynamic membrane reactor (PAC-DE DMR) is designed for low turbidity raw surface water treatment. Experimental results indicated that the reactor had the advantages of high ?ltration ?ux, high removal efficiency of the pollutants, and low filtration resistance. The filtration process of the dynamic membrane obeyed the standard filtration model. The scanning electron microscopy analysis indicated that the dynamic membrane consisted of cake layer, gel layer and the support layer, and the gel layer was tightly adhered to the support layer. The gel layer was formed by the PAC-DE particles and microbial products, which made the self-forming time of dynamic membrane short.
