Problems solved by technology

For example, the Chinese patent application whose publication number is CN 104524965 A utilizes ceramsite, nutrients and other materials to form regular shape biological fillers. A large amount of nutrients are beneficial to the growth of microorganisms, and the fillers shrink during the molding process. No effective buffs, limited strength stability
The Chinese patent application with the publication number CN 105597696 A uses the bamboo charcoal powder on the surface of the filler to adsorb pollutants in the water phase, and then absorbs and purifies them through microorganisms. However, the composition of VOCs is complex and most of them are hydrophobic. The effective adsorption capacity of pollutants is not significant, which increases the difficulty of obligate microorganisms in the treatment of pollutants and reduces the treatment efficiency
[0005] For the development of biological fillers, the domestic technology is uneven, and the development and production of biological fillers with unique properties are still in the preliminary stage. When dealing with hydrophobic components, the limitations are more obvious. Enterprises that really invest a lot of manpower and material resources in the research and development of biological fillers There are only a handful of them, so that the country has not found a method that can simply and effectively absorb and degrade VOCs with complex components

Abstract

The invention discloses bio-filler for absorbing and degrading hydrophobic organic waste gases, and a preparation method of the bio-filler. The bio-filler is prepared from the following raw materials:modified iron-based beta-cyclodextrin, diatomaceous earth, biochar, ceramsite, calcium oxide, silicate inorganic gel and water. The preparation method of the bio-filler comprises the following steps:dissolving the modified iron-based beta-cyclodextrin and the calcium oxide to obtain sol A; evenly mixing the diatomaceous earth, the biochar and the silicate inorganic gel to obtain powder B; dipping the ceramsite into the sol A for 5min, then placing the product in a drum granulator for granulating together with the powder B, spraying the sol A in the granulation process so as to obtain preliminarily-cured gel granules, and curing to obtain the bio-filler for absorbing and degrading the hydrophobic organic waste gases. The bio-filler prepared by the method can be widely applied to various types of organic waste gas biological purification systems, and enables the hydrophobic organic waste gases to more easily penetrate a wet water film on the surface of the filler and be in contact withmicroorganisms so as to enable the hydrophobic organic waste gases to be subjected to efficient catalytic degradation.

Description

technical field [0001] The invention belongs to the technical field of material chemistry and environmental protection, and in particular relates to a biological filler for adsorbing and degrading hydrophobic organic waste gas and a preparation method thereof. Background technique [0002] At present, it is the general trend for the country to tighten the emission limits of organic pollutants. How to ensure that the concentration of organic pollutants reaches the standard in the future, it is urgent to upgrade the existing organic pollution control technology to adapt to the new emission standards. As my country pays more and more attention to volatile organic pollutants (VOCs) and environmental protection regulations continue to strictly control the emission of VOCs, VOCs treatment technology is gradually improving and perfecting. The main reason why VOCs are difficult to deal with is because of their wide variety and wide sources. The complex organic pollution waste gas i...
