Biomass adsorbent and preparation method thereof

Abstract

The invention discloses a biomass adsorbent, which belongs to the field of waste gas treatment. The biomass adsorbent consists of punched corn cobs or straw cores and microbial agent coated thereon. The invention also discloses a preparation method for the biomass adsorbent, which comprises the following steps of: punching a hole with diameter of 0.5 to 1 centimeter in the center of each corn cobor straw core by using a punching machine, then spraying the microbial agent capable of decomposing harmful compounds in the waste gas onto the punched corn cobs or straw cores, and finally, sequentially piling the punched corn cobs or straw cores sprayed with the microbial agent into a waste gas adsorption pipeline. The simply processed biomass corn cobs or straw cores are used as a special gas adsorption material for waste gas treatment, so the gas generated by composts can be effectively purified, the cost is low, the equipment is simple, the rural waste resources are fully utilized, and recycle of agricultural waste resources is really realized.

Description

A kind of biomass adsorbent and preparation method thereof technical field The invention belongs to the field of waste gas treatment, and in particular relates to a biomass adsorbent and a preparation method thereof. Background technique During the process of fermentation industry, food industry production, agricultural waste composting, etc., a large amount of waste gas will be generated. If it is directly discharged into the environment without treatment, it will cause varying degrees of pollution to the atmosphere. The principles of exhaust gas treatment mainly include activated carbon adsorption method, catalytic combustion method, catalytic oxidation method, acid-base neutralization method, probe plasma method, etc., but most of these methods are expensive, complicated to operate, and easy to cause secondary pollution. Not widely applicable. In rural areas, there are a large amount of biomass such as corncobs and straw cores. These biomasses can be used as a new type...
