Waste gas treatment equipment of biological filter

Abstract

The invention discloses waste gas treatment equipment of a biological filter. The waste gas treatment equipment of the biological filter is composed of an inner barrel and an outer barrel, which have a sleeve type design, wherein the inner barrel 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; the inner barrel biological filter bed is internally provided with plastic packing; the inner barrel further comprises an inner barrel nutritional solution storage groove, an inner barrel nutritional solution circulating pump and an inner barrel nutritional solution circulating pipeline for connecting the inner barrel nutritional solution storage groove and the inner barrel annular water distributor. Each grade of the filter adopts packing with different properties, an independent circulating nutritional solution system and corresponding supporting facilities, so that the requirement of efficiently removing gas-state pollutants with different properties can be met; and the waste gas treatment equipment of the biological filter can be used for laboratory research, domestic sewage treatment engineering and part of small-sized industrial and agricultural waste gas treatment engineering.

Description

technical field [0001] The invention relates to a waste gas biological treatment device, more specifically, to a biological filter waste gas treatment device. 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 waste gas treated by the biological trickling filter has a large flow rate (generally controlled at 0.015 - 0.03 m / s), and the residence time in the biological trickling filter is short (only 20-30s). Therefore, effectively using the biomass in the...

Problems solved by technology

The design of the biological trickling filter system needs to consider the limitations of the above factors in order to achieve better exhaust gas pollutant removal effect. However, the existing biological trickling filter and its deformation form are rarely designed according to the different properties of the pollutants. Multifunctional integrated biofilter to control the growth of biofilms with different properties and quantities to meet the requirements of different pollutant removal
