Embodiment Construction
[0015] The present invention mainly considers the following factors. 1) The height of the sedimentation zone in the reactor is not high enough, so that the solid-liquid mixture stays in the sedimentation zone for not long enough, resulting in poor sedimentation effect, which is not conducive to solid-liquid phase separation, and when the immobilized microbial filler is used to treat sewage, the immobilized microbial If the height of the packing is not enough in the sedimentation zone, it is easy to lose with the water flow. Therefore, the height of the sedimentation zone was appropriately increased in the design of the reactor, which is not only beneficial to the separation of solid and liquid phases, but also can effectively prevent the loss of immobilized microbial fillers. 2) For the reflux of the general reactor, a reflux device must be connected outside the reactor. The use of the reflux device will lead to the overall structure of the reaction device being not compact en...
