Embodiment Construction
[0019] The present invention will be further described below in conjunction with specific examples.
[0020] The device used in the present invention is a vertical biological trickling filter tower, which is mainly composed of a gas distribution system, a liquid distribution system and a biological treatment system. The main body of the biological trickling filter is a plexiglass tube with an inner diameter of 85mm and a height of 1000mm. The plexiglass tube is divided into 2 sections, and each section is equipped with 2.84×10 -3 m 3 Ceramsite is used as filler, its particle size is 2-3mm, 1.8g / cm 3 , specific surface area 1.3m 2 / g. The bottom of the packing is supported by flanged bulkheads. There are round holes with a diameter of 25mm in the two sections of the plexiglass tube, which are respectively connected to the two ends of the U-shaped pressure gauge. The air distribution system is mainly composed of air blowing pump, toluene generator bottle, mixing bottle, ro...
