Research Progress of the Influencing Factors for Flocculating Effect and the Water Treatment Technologies of Microbial Flocculants*

The developments of microbial flocculants in recent years were summarized in this review. It discussed the chemical properties of microbial flocculants and the related factors which infuenced the flocculating activity of microbial flocculants, including dosing quantity, dosing sequence, properties of water to be processed and hydraulic conditions. It focused on the water treatment process of microbial flocculants alone, the compounding of microbial flocculants and coagulants, the composite microbial flocculants and the joint treatment of the physical and chemical methods and the microbial flocculants. It had found that exploring new water treatment technologies combined with the existing research results had important value for industrial application.
