Preparation method of macromolecule activated carbon composite filler

Abstract

The invention discloses a preparation method of macromolecule activated carbon composite filler. The preparation method comprises the following steps: fixing fungi with special effect, which is cultured for harmful pollutant, into powdery activated carbon by adopting a microorganism fixing method, then mixing a macromolecule material prepared from polyving akohol and sodium alga acid with activated carbon particles by adopting a crosslinking method, and fixing a mixture on an corrosion-resistant fabric vector with a certain shape, thereby preparing the fixed biological compound filler. The macromolecule activated carbon composite filler provided by the invention has high resilience, is internally provided with a rich net-shaped structure and is beneficial to the adherence and growth of cells; the types and quantity of effective degraded fungi can be controlled, the processing capability of equipment can be greatly improved, the time at the initial stage of starting of waste gas biological processing equipment is shortened, due to large increase in effective area and effective fungus types, the occupied areas and the investment expense during the waste gas processing are reduced compared with those of a common biological method, so that the preparation method of the macromolecule activated carbon composite filler has important popularization value.

Description

technical field [0001] The invention relates to a method for manufacturing a polymer activated carbon composite filler for treating waste gas, in particular to a method for manufacturing a polymer activated carbon composite filler for treating malodorous and organic waste gas. Background technique [0002] In industrial production, along with the processing and manufacturing of products, a large amount of harmful gases, such as various malodorous substances and volatile organic compounds, will be produced. In the absence of effective control and treatment, these exhaust gases will stimulate and poison the human body, greatly endangering human health and the ecological environment. There are many ways to deal with this kind of waste gas, among which biological filtration technology is one of the effective methods to deal with this kind of waste gas. The method is to use a filter or reaction tower equipped with a biological packing layer. When the wetted exhaust gas passes th...

AI Technical Summary

Problems solved by technology

The microorganisms in these fillers need a process of inoculation attachment and culture proliferation. For some special degrading bacteria with a small number in the natural environment, a longer enrichment time is required, and the types and quantities of effective bacteria in the filler after cultivation cannot be determined. Human control, which limits the treatment capacity, is mostly used to treat low-concentration organic waste gas

When the concentration of organic matter in the exhaust gas is high, the particulate matter in the exhaust gas accumulates too much in the filter bed and the biomass grows rapidly, which easily leads to plugging of the packing, the resistance of the gas passing through the tower body increases, and problems such as gas short circuit occur, which affect the mass transfer effect. The thickness of the filler layer is limited, generally only about 30-1000mm

Due to the large resistance and thin packing layer, it is usually necessary to increase the cross-sectional area of ​​the filter bed to expand the treatment capacity of waste gas, resulting in a large footprint of the entire treatment device.
