Background
The sulfate pulp mill in the paper making industry is generally provided with a high-concentration odor collecting and treating system, and compared with the sulfate pulping process, the low-concentration odor generated in the production and storage processes of waste paper pulping is discharged after being simply washed, so that the odor cannot be effectively removed. From fisher' S law, S-KlgI + C (S is the amount of human odor, K is a constant, I is the odor concentration, and C is an integration constant), it can be seen that the amount of human odor perception is reduced by less than half even if the concentration of low-concentration odor is 10% of high-concentration odor. Therefore, the problem of low strong odor is also an urgent problem to be solved at present.
In the process of recycling and pulping waste paper, a series of odor problems can be caused by the application of deinking chemicals and bleaching chemicals, the bacteria breeding problem caused by closed recycling of white water and other factors. Particularly, as the import of foreign waste is limited, domestic waste becomes the main raw material of the current waste paper making enterprises, because the domestic waste contains a large amount of sizing starch, and as the white water is recycled in a closed way, a large amount of organic substances such as starch and the like are accumulated, a sufficient carbon source is provided for microorganisms, and anaerobic bacteria in a pulp tank, a pulp tower and a pipeline cause the carbohydrase to ferment to generate volatile fatty acid with unpleasant smell. And because the accumulation of organic matters such as protein, starch and the like in water provides rich nutrient substances for the breeding of bacteria, the peripheries of cell walls of the bacteria can generate capsules which are sticky substances consisting of sugar and polypeptide, the capsules can ensure that the bacteria can be adhered to the surfaces of the inner walls of the pulp tower and the pulp tank, a large amount of rotten pulp is formed after growth and reproduction, and the rotten pulp can generate volatile irritant gas such as hydrogen sulfide, so that the timely cleaning of the inner walls of the pulp tower and the pulp tank is another way for controlling the generation of odor.
