Description

Photocatalytic treatment system for degrading harmful gases

This invention relates to a treatment system, in particular to a photocatalytic treatment system that can degrade harmful gases such as ammonia.

According to the report, due to the development of livestock-related industries in Taiwan in recent years, the amount of various organic wastes generated each year is extremely large. Especially in some large agricultural counties, the competent authorities are looking for effective solutions for the odors derived from composting sites or livestock farms. These numerous livestock wastes, agricultural wastes, forestry and aquatic wastes, a total of 2,000 tons are generated each year. If they are not properly and quickly handled, they will become a serious source of pollution and have a great negative impact on the environment and ecology.

In the past, there were many examples of composting sites being shut down and livestock farms being relocated due to environmental pollution. Usually, during the composting process in a composting site, when the organic load is too high and the oxygen is insufficient, foul-smelling gases such as indole, skatol, hydrogen sulfide, ammonia, volatile amines, and mercaptans will be produced. Among them, ammonia is the main source of foul odors emitted from composting sites. After actual investigation, when composting sites are "highly fermented", the peak concentration of ammonia is as high as 1,200ppm and the average is 800ppm. Such a high concentration is already a "toxic" pollutant and should not be ignored. In addition, the production of ammonia (NH ₃ ) is the most worrying problem in the poultry production process. When birds ingest protein, they produce uric acid, which is eventually converted into ammonia under the right conditions. In addition to high concentrations of ammonia produced by highly fermented composting processes and poultry production processes, high concentrations of this pollutant have also been found in the exhaust of fish and livestock residue processing, feed industry and food processing plants.

Furthermore, the medical community has also confirmed that long-term exposure to high concentrations of ammonia (>500ppm) may cause fatal injuries, severe pulmonary edema, convulsions, respiratory paralysis, severe hemolytic anemia, coma, and even rapid death; if not properly handled, it will not only easily cause environmental pollution, but will also directly or indirectly affect the quality of life and health of workers or nearby residents. Therefore, how to degrade high concentrations of ammonia and other harmful gases is a problem that the industry is currently eager to solve.

In view of this, this invention provides a treatment system, especially a photocatalytic treatment system that can degrade harmful gases such as high-concentration ammonia, as its main purpose.
