Different distributed sewage treatment processes and various oxygenation methods in an aerobic zone comprise micropore aeration, perforation aeration, micro-nano aeration, a dynamic jet aerator and the like.
The Chinese patent publication No. CN109502777A discloses a high-efficiency jet injector, which performs high-efficiency jet aeration and oxygenation by gas-liquid mixing and pumping, and although the mass transfer effect of the jet mode is improved, the aeration efficiency is improved to a certain extent, a power device is needed, the operation cost is increased, and gas-liquid mixing is needed, organic carbon in sewage is digested by aerobic bacteria, so that the carbon source in an anoxic and anaerobic zone at the front end is insufficient, and the carbon source needs to be additionally supplemented, and the operation cost is increased.
The device conveys sewage into a bubble generator through a power device, a gas-liquid mixture is obtained and then goes downwards, the bubbles of about 1mm are obtained through a bubble refiner, and the gas-liquid mixture is aerated and oxygenated from the bottom in the horizontal direction in an inclined upward manner. On one hand, the device can ensure the retention time of oxygen, but a pumping system is needed to ensure the uniformity of gas-liquid mixing, and the power of a sewage pump is far greater than that of an air pump, so that the energy consumption is much higher than that of a system without the pumping system; on the other hand, the problems that organic carbon in sewage is digested by aerobic bacteria due to gas-liquid mixing and a carbon source in a front end anoxic-anaerobic zone is insufficient exist, and the carbon source needs to be additionally supplemented, so that the operation cost is increased.

The micro-nano hole aeration pipe disclosed in the patent with the Chinese patent publication No. CN208632221U has the advantages of simple structure, convenient assembly and disassembly and good oxygenation effect; however, in the case of a slightly large aerobic zone, when the observation port is small, the device is difficult to assemble and disassemble; and because the elastic micro-nano hole pipe is sleeved outside, the hole diameter is small, the turning effect of the whole aerobic zone is difficult to form, the filling is easy to accumulate, the influence on the mass transfer process and the digestion effect is great, and the elastic micro-nano hole pipe is particularly not suitable for the aerobic zone of the sponge filling, because the filling of sponges easily grows a thick biological film, and the sponge filling with a certain weight is turned under the pressure formed by micro-nano hole bubbles.
Although the aeration device disclosed in the patent with the Chinese patent publication No. CN207877403U has a simple structure, the aeration effect of the micro-nano holes is difficult to form by the air pressure, the mass transfer effect of a biological film on the filler and organic matters in sewage is insufficient, the contact time is short, and the digestion effect is influenced.
