Abstract： |
The present invention belongs to the field of waste water treating technology, and is especially repeated aerobic-anaerobic microbe coupling process of treating waste water in environment protection. Biological fluidizing beds and biological fixed beds are connected serially with overflow partition boards and added with two different kinds of porous biological carriers. Via repeated aerobic-anaerobic microbe coupling in different layers, the present invention disposes organic matter and nitrogen compound in waste water while in-situ decomposing sludge. The present invention realizes the effective elimination of organic matter and nitrogen in waste water, the forced separation of the solid particles from water in the fixed beds and the digestion, degradation and final complete decomposition of solid matter. The present invention has high efficiency, low power consumption and low running cost. |
