Problems solved by technology

[0004] At present, the method of removing formaldehyde in China is mainly to use some activated carbon and diatoms sold on the market to adsorb formaldehyde, but the cost of these materials is relatively high, and their adsorption is limited, which is easy to cause secondary pollution

Embodiment Construction

[0031] In order to make it easy to understand the technical means, creative features, work flow, and use methods of the present invention to achieve the purpose and effect, the present invention will be further elaborated below.

[0032] A method for preparing an environmentally friendly original ecological green biosorbent, the process flow is: material→sampling→slicing→cooking→pressing→filtering, rinsing until neutral→soaking in alkali→drying→crushing→sieving→finished product; the specific steps are as follows :

[0033] Sampling: choose lettuce leaf, watermelon peel, orange peel, wheat bran as material, and rinse;

[0034] Cooking: steaming 10-30min with boiling water;

[0035] Squeeze: add water to squeeze into material slag;

[0036] Filtration and rinsing until neutral: filter the material residue, take the filter residue and rinse it with running water until neutral;

[0037] Alkaline soaking: Soak the filter residue rinsed to neutral in an alkaline solution with a p...

Abstract

The invention relates to an environment-friendly primitive ecological green bio-adsorbent preparation method. The technical process comprises the following steps: selecting materials, sampling, slicing, boiling, pressing, filtering, rinsing to neutral, soaking with alkali, drying, pulverizing, and screening to obtain a finished product. According to the invention, the primitive ecological bio-adsorbent material is prepared from the following common domestic wastes: asparagus lettuce leaves, watermelon peels, orange peels and wheat bran; systematic research is performed on the formaldehyde adsorption rate through quadratic regression orthogonal rotation combined design to optimize formaldehyde adsorption conditions; certain achievements are got in comparison with the traditional activated carbon adsorption test research; the preparation method provides a theoretical basis for application of peels and other wastes, and provides a reference for effective purification of formaldehyde pollution in habitable rooms; and in case of going into production, the preparation method can realize waste recycling and create a win-win situation of treating wastes with processes of wastes against one another, thereby having positive meanings for realizing both circular economy development and environment protection.

Description

technical field [0001] The invention belongs to an adsorbent for formaldehyde gas in a living room, in particular to a preparation method of an environment-friendly original ecological green biological adsorbent. Background technique [0002] Indoor air pollutants include some indoor toxic and harmful gases, such as formaldehyde, benzene, ammonia, carbon oxides, etc. Formaldehyde, as one of the main pollutants of indoor air, is also the most common, serious and most concerned pollutant, with a wide range of sources. A large number of studies at home and abroad have shown that a large number of decorative materials, furniture and coatings used in the decoration process are the main sources of indoor air pollution, such as building structural materials and decorative materials. Formaldehyde mainly exists in the deep part of decorative materials, and has the characteristics of slow release speed and long release time. At present, there are many kinds of adhesives, and the most...
