Abstract

The invention discloses a biologically-enhanced waste gas treatment device, which comprises an inner cylinder and an outer cylinder which are designed in a sleeve manner, wherein the inner cylinder comprises a first gas collecting hood, an inner barrel annular water distributor, an inner barrel biological filter bed, a first supporting layer and a flow guide barrel which are arranged in sequence,the first supporting layer is arranged at the bottom of the inner barrel biological filter bed, a plastic filler is arranged in the inner barrel biological filter bed, and the inner cylinder further comprises an inner barrel nutrition solution storage tank, an inner barrel nutrition solution circulating pump and an inner barrel nutrition solution circulating pipeline connected with the inner barrel nutrition solution storage tank and the inner barrel annular water distributor. According to the present invention, various stages of filtration tanks respectively adopt fillers with different properties, independent circulation nutrition solution systems and corresponding supporting facilities, such that the efficient removal requirements of gaseous pollutants with different properties can be met, and the device can be used for laboratory research, domestic sewage and a part of small industrial and agricultural waste gas treatment engineering.

Description

technical field [0001] The invention relates to a biologically enhanced waste gas treatment device, which belongs to the technical field of waste gas treatment equipment. Background technique [0002] With the development of cities and industries, a large amount of waste gas is discharged into the atmosphere. There are various types of pollutants in the waste gas and their components are complex. There are complex synergies (reaction and antagonism) among the pollutants, which cause serious harm to the human body. , there is an urgent need for cost-effective treatment processes and technologies. Biological method is an economical and effective means of waste gas treatment, the most important form of which is biological trickling filter. The flow rate of the waste gas treated by the biological trickling filter is large (generally controlled at 0.015-0.03m / s), and the residence time in the biological trickling filter is short (only 20-30s). Therefore, effectively using the b...
