Embodiment Construction
[0023] The present invention will be further described in detail below in conjunction with specific embodiments.
[0024] In this example, a four-layer biological trickling filter is used to treat ethylbenzene waste gas, and a surfactant and its co-solvent are used to enhance the removal efficiency of the device for ethylbenzene.
[0025] The main body of the device is two plexiglass columns with an inner diameter of 100 mm and a height of 780 mm. The column is equipped with four layers of polyurethane sponge packing (10 PPI) with a diameter of 100 mm and a height of 100 mm, and the layers are separated by sieve plates with dense small holes. The wetted ethylbenzene gas is passed into the column through the upper air inlet, and is discharged from the lower air outlet after being treated by the microorganisms grown on the filter material. The nutrient distribution system of the device consists of a spray device at the top of the column, a water pump, and a nutrient solution st...
