Ozone has strong oxidizing property, the oxidizing capability of the ozone is second to that of fluorine and higher than that of chlorine and potassium permanganate, and the ozone can be automatically decomposed in a short time without secondary pollution, so the ozone is an ideal green oxidizing agent. However, the cost of ozone oxidation alone is high, and most of macromolecular organic matters can only be oxidized into micromolecular organic matters, but the organic matters cannot be completely removed. The membrane aeration bioreactor is essentially a biofilm method, namely a treatment unit which fills biological fillers in an aeration tank and degrades pollutants in water by utilizing the biological membranes attached to the surfaces of the fillers. Due to the characteristics of the selected filler, the surface of the filler is easy to be attached with a biological film. Numerous species and numbers of microorganisms, including aerobic bacteria, facultative bacteria and anaerobic bacteria, grow in the biological membrane, so that the biological aerated filter has a good removal effect on various organic matters in water, and has high removal efficiency on ammonia nitrogen. However, although the biological aerated filter has high efficiency, the biological aerated filter is only suitable for the advanced treatment of low-concentration sewage and the treatment of water sources with raw water micro-pollution, and can not remove organic matters which are difficult to biodegrade.
