Problems solved by technology

[0005] (2) Calcium alginate embedding bacteria method, but CaCl is required for calcium alginate embedding 2 The surface of the solution can be solidified to form a film, and the increase in Ca2+ concentration will also increase the impact on bacterial activity. Again, the polymer film on the surface of calcium alginate microspheres will also prevent the entry of nutrients and air, resulting in reduced bacterial activity and resistance to formaldehyde. Reduced absorption efficiency;
[0006] (3) The development of green plants and their transgenes can increase the efficiency of absorbing formaldehyde, and can continuously absorb indoor formaldehyde, but the disadvantage is that green plants need suitable temperature, light, and watering on time, and cannot be placed in dark places such as wardrobes. If the new house is not occupied, watering on time is too troublesome

Abstract

The invention relates to a formaldehyde microbial purifier for building ventilation engineering, and belongs to the technical field of environmental protection, a method comprises the following steps: screening a strain capable of efficiently degrading formaldehyde, embedding the formaldehyde degrading strain with gelatin, algin and inulin, adding a nutrient solution for use, paving a plurality of layers of glass balls in an inner cavity of the purifier, the formaldehyde microbial purifying agent is placed in gaps among the plurality of layers of glass balls. The purifier provided by the invention can be used as an effective formaldehyde scavenger, and has an obvious formaldehyde degradation effect and a long maintenance time.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a formaldehyde microbial purifier used in building ventilation engineering. Background technique [0002] As an important adhesive component, formaldehyde is widely used in the manufacturing industry. Due to its non-specific damage to proteins and nucleic acids, formaldehyde has a strong toxic effect on organisms. With the development of industry and the generalization of interior decoration, formaldehyde pollution in the air is becoming more and more serious. It is particularly important to find an economical and effective formaldehyde removal method without secondary pollution. At present, there are three main methods, the physical method is inefficient, and the most used is activated carbon adsorption, but the activated carbon will be saturated, and formaldehyde will be released under certain conditions to cause secondary pollution; the chemical method is effi...
