DETAILED DESCRIPTION - A mobile sewage treatment station combined with unit-type membrane with biological decomposition, comprises biological treatment pool and tubular hollow fiber membrane filter. The outer side of sewage treatment chamber is provided with moving device. One side of sewage treatment chamber is provided with electrical cabinet and hollow fiber membrane filter device; and the other side is provided with biological treatment pool. The end of biological treatment pool is provided with regenerated water circulation chamber. The outlet pipe of regenerated water circulation chamber is connected with inlet of regenerated water pump. The outlet of regenerated water pump is connected with regenerated water pipe in hollow fiber membrane filter device. The hollow fiber membrane filter device comprises tubular hollow fiber membrane filter group, regenerated water pipe, purified water pipe, circulating water pipe, pneumatic butterfly valve, manually operated valve, water pressure gauge, measuring pump, flow meter, back-washing water pipe, back-washing device and electric contact water pressure gauge. The regenerated water pipe is distributed with tubular hollow fiber membrane filter group having tubular hollow fiber membrane filters. The inlet in lower end of each tubular hollow fiber membrane filter is connected in regenerated water pipe. The pipe section in one end of regenerated water pipe between regenerated water pump and tubular hollow fiber membrane filter group, and the pipe section in one end of circulating water pipe between regenerated water circulation chamber and tubular hollow fiber membrane filter group are sequentially provided with pneumatic butterfly valve, manually-operated valve and electric contact water pressure gauge. The other end of regenerated water pipe is connected with one end of pneumatic butterfly valve. The other end of pneumatic butterfly valve is connected with blow off pipe. The end of blow off pipe is sewage draining exit. The other end of blow off pipe is connected in circulating water pipe. The other end of circulating water pipe is connected with regenerated water circulation chamber. The side outlet in upper part of every tubular hollow fiber membrane filter is connected in pipe section of circulating water pipe. The pipe section in the other end of circulating water pipe is connected with pneumatic butterfly valve. The outlet in upper end of each tubular hollow fiber membrane filter is connected in pipe section in one end of purified water pipe. The pipe section of the other end of purified water pipe is sequentially connected with measuring pump and pneumatic butterfly valve. The end of purified water pipe is connected in pipe section of back-washing water pipe. Each pipe section of back-washing water pipe for connecting two sides of ends of purified water pipe is sequentially connected with manually operated valve. One end of back-washing water pipe is connected with regenerated water circulation chamber. The other end of back-washing water pipe is connected in back-washing device. The bottom surface in chamber in front side of tubular hollow fiber membrane filter group is provided with air pressure accumulation tank. The pipelines of air pressure accumulation tank are separately connected with inlet in lower end of tubular hollow fiber membrane filter group and air distribution pipe tie-in (19). The bottom surface in corner of chamber that is opposite to tubular hollow fiber membrane filter group is provided with electrical cabinet. The working procedures of hollow fiber membrane filter group are automatic.
