Odor sources and damages£º |
|
| |
¡¡Offensive odors mainly come from urban sewage, sludge and garbage disposal. |
| |
¡¡These odors do great harm to human¡¯s respiratory and digestive systems, cardiovascular, endocrine and nervous systems. Even worse than that is people who expose to a high concentration of odor may suffer pulmonary edema or even die by suffocating. |
| |
¡¡Odor pollutants could disturb people¡¯s normal life, causing lower work efficiency. Normal production could also be affected, causing deterioration of social economy. |
| ¡ô |
National rules and regulations on odor pollutants£º
|
| |
Waste gases must be well treated to meet China¡¯s Emission Standard for Odor Pollutants. The following table gives related standards.

Basic principle£º |
| |
Under appropriate circumstance, microbes attached to the bio-filter medium could consume waste gas pollutants and decompose them. As a result, the pollutants are broken down into CO2, H2O and various inorganic salts and thus waste gas is cleaned.
¡¡ Wastewater resulting from the above process is ready to discharge after simple treatment, not resulting in secondary pollutants |
¡ô |
Explanations to the chemical technology£º |
| |
Natural microbes are strictly selected and rationally graded to serve as filter medium. Meanwhile, nutrient solution is sprayed on moistened waste gas so as to create an appropriate environment for microorganism growth.
In addition to low investment and operating costs, HISUN bio-filter beds for deodorization have realized unmanned operation. |
