Background

Membrane-aerated bioreactor (MABR) is a product of the combination of membrane technology and biofilm technology, which supplies oxygen through a gas permeable membrane, and under the condition of keeping the gas partial pressure lower than the bubble point, the oxygen in the membrane lumen passes through the micropores on the membrane wall and enters the outside of the lumen, thus realizing bubble-free aeration. The bubble-free aeration mass transfer efficiency is high, the oxygen utilization rate can approach 100 percent, and the oxygen utilization rate is 5 to 7 times that of the traditional aeration.

The membrane material of the MABR can be used as a carrier, a microbial membrane can be formed on the membrane surface, oxygen from the inner side of the membrane lumen diffuses from the inside of the biological membrane to the outside, and substrates from sewage diffuse from the surface of the biological membrane to the inside. Because of the anisotropic mass transfer of oxygen and a substrate, the microbial membrane on the membrane component generates an obvious layered structure which is respectively an aerobic layer, a facultative layer and an anaerobic layer from inside to outside. The microbial membrane in the MABR is functionally layered, so that the microbial membrane can independently complete the oxidation and synchronous nitration of organic pollutants in sewage. In the use process of the existing membrane aeration bioreactor, when a surfactant exists in wastewater, foam is easy to generate and is not easy to remove, and due to the fact that the sludge concentration in an aeration tank is increased, the problem of membrane pollution often exists in the actual operation process, membrane components need to be cleaned often, so that the defects of short service life of membranes, high maintenance cost and the like exist, and therefore, an integrated sewage treatment device based on an MABR is provided for solving the problems.
