[0043] Example 1:
[0044] See figure 1 , A closed self-draining type biofiltration membrane module, comprising a self-draining filter 1 on which microorganisms are cultivated, and the upper and lower ends of the self-draining filter 1 are respectively equipped with a tubular filter 2 and a microfiltration membrane 3 , The inner end of the tubular filter 2 is excavated with a net-shaped flow channel, the outer end of the tubular filter 2 is fixedly connected with a connected air inlet pipe, and the lower end of the tubular filter 2 is fixedly connected with a plurality of evenly distributed air filling pipes 6, and The refueling pipe 6 is matched with the deformed oxygen storage ball 4 and communicated with the net-shaped flow channel. The tubular filter 2 initially filters large-diameter pollutants while reducing the filtration pressure of the self-draining filter 1 and the tubular filter 2 At the same time, it can establish a communication pipeline with the deformed oxygen stor...
