Preparation method and application of novel adsorbent resin

Abstract

The invention provides a method for preparing novel adsorbent resin, which comprises the following process steps of: (1) dissolving sodium alginate and nutritional components of a yeast peptone dextrose (YPD) medium in water, heating for dissolving, cooling to room temperature, adding kaolin, sodium hydrogen carbonate and polyethylene glycol to obtain mixed solution, and dripping into calcium chloride solution to prepare gel particles; (2) heating the gel particles to obtain porous gel particles; and (3) drying the porous gel particles at 85DEG C for 15 minutes, cooling, putting into yeast suspension, and culturing to obtain the novel microorganism-loaded absorbent resin. The resin has double performance of oil absorption and water absorption; the porous gel particles prepared from the sodium alginate serve as a microorganism carrier; in organic waste gas treatment application, adsorption and biological treatment are integrated; and the resin can be recycled and is not needed to be regenerated, so that cost and operating expense are saved.

Description

Preparation method and application of a new type of adsorption resin technical field The invention relates to the field of adsorbent and environmental technology, in particular to a novel adsorption resin, especially a preparation method of an adsorption resin loaded with microorganisms and its application to adsorption and purification of organic waste gas. Background technique With the continuous advancement of science and technology, various pollution problems have become increasingly prominent. In the process of chemical, plastic, adhesive production and spraying, a large amount of organic waste gas containing volatile organic compounds is produced. If it is discharged into the atmosphere without treatment, it will form photochemical pollution under certain conditions and cause serious air pollution; and Most of these compounds are toxic, and some of them have been listed as carcinogens, such as formaldehyde, vinyl chloride, benzene, polycyclic aromatic hydrocarbons, e...

Problems solved by technology

Activated carbon adsorption is the most commonly used organic waste gas treatment method at present. It has high adsorption efficiency and good treatment effect. It has good adsorption performance for waste gases containing benzene, toluene and xylene, but poor adsorption for hydrocarbon waste gases.

However, activated carbon adsorption and regeneration is difficult, the operating cost is high, and it is not suitable for treating organic waste gas with high humidity. This is the bottleneck that hinders the use of activated carbon adsorption, and in terms of the nature of activated carbon itself, this weakness is insurmountable.
