Abstract

The invention belongs to preparation methods of environment-friendly original ecological green bio-adsorbents, particularly relates to a method for preparing a formaldehyde adsorbent by wine making residues, and mainly solves the problem of wine making residue waste resource reuse. The technical scheme includes that raw materials are treated, dried, sheared, digested, soaked in ammonium oxalate, soaked in alkali liquor, dried and crushed into particles to obtain a finished product. Formaldehyde adsorption rate is systematically researched by quadratic rotary orthogonal experiment combination design to optimize formaldehyde adsorption conditions. Compared with traditional adsorption experiment research of activated carbon, pure diatom, bamboo charcoal and the like, the adsorption effect ofthe formaldehyde adsorbent is superior to that of the materials, so that a theoretical basis is provided for wine making residue resource application, and a reference is provided for effectively purifying formaldehyde pollution in air. Waste resource reuse can be realized if the formaldehyde adsorbent can be brought into production, the win-win situation of waste control by waste is achieved, andthe method has positive significance for economic cycle development and environmental protection.

Description

technical field [0001] The invention belongs to the preparation method of an environment-friendly original ecology green biological adsorbent, and in particular relates to a method for preparing a formaldehyde adsorbent by using grape wine residue. Background technique [0002] Today, human beings are facing "soot pollution" and "photochemical smog pollution", among which the most harmful ones are: formaldehyde, benzene, ammonia, esters and trichlorethylene. A large number of facts have confirmed that indoor air pollution has become an "invisible killer" that endangers human health. Formaldehyde has been identified as a class of carcinogens by the World Health Organization, and it is believed that there is a causal relationship between formaldehyde and leukemia. [0003] The products currently on the market that adsorb formaldehyde mainly include activated carbon, bamboo charcoal, diatoms, super oxygen purifiers (Germany), green foliage plants, etc. Activated carbon needs ...
