Alternatively biological filter pool waste gas treatment equipment

The utility model relates to a biological filter pool waste gas treatment device composed of a pre-treatment device, a fixed bioreactor and a gas communication pipe. The pre-treatment device is provided with an air outlet. The fixed bioreactor is provided with an inlet port. The gas communication pipe is respectively communicated with the air outlet and the inlet port. The utility model is characterized in that the fixed bioreactor is provided with at least two inlet ports; the upper part and the lower part of the fixed bioreactor are respectively provided with an inlet port. The utility model overcomes the prejudice and the habit that the fixed bioreactor with the prior art is only provided with an inlet port. The utility model is provided with at least two inlet ports to obtain air admittance from a plurality of ports and make the alimentation of the filler in the fixed bioreactor homogeneous. The microbial biomass cultivated is homogeneous. That the biological film on the filler of the admission end is thicker to cause the block can be avoided. The utility model can enhance the load-carrying capacity of resistance to impact and make full use of the volume of the filler.
