<p>PURPOSE:To prevent a pellet separation device from plugging due to the generation of a biological film by filling the treated water side of the device with a filler which helps habitation for microbes. CONSTITUTION:This waste water treatment device uses immobilized microbe pellets 12 which immobilize microbes with a polymer substance entrappingly, and at the same time, is equipped with a mesh or a linear pellet separation device 18 for separating a water-to-be-treated side from a treated water side near an outlet of treated water. In addition, a filler 20 for microbial habitation which facilitates the proliferation of microbes is provided in the space of the treated water side.</p> |
