Abstract

The invention relates to a high-efficiency biological deodorizing technology and system. A primary treatment unit in a biological reactor with an integral two-stage cascade structure is used for treating to-be-treated gas to remove most of pollutants; then a secondary treatment unit in the biological reactor with the integral two-stage cascade structure is used for treating pollutant gas from the primary treatment unit to remove residual pollutant, and the treated gas is exhausted out of the biological reactor; fillers in the primary treatment unit are volcanic rock, fishshell and sulfur and iron ore slag, and fillers in the secondary treatment unit are volcanic rock and fishshell. The high-efficiency biological deodorizing technology and system have the beneficial effects that the land occupation area of the biological deodorizing equipment and the total water usage amount of the biological deodorizing system are effectively reduced, the service life of the fillers is prolonged, the pressure loss of the system is reduced, the stability of the biological deodorizing system is enhanced, and the treatment efficiency of the biological deodorizing system on various pollutants is improved.

Description

technical field [0001] The invention relates to the field of odor control, in particular to a high-efficiency biological deodorization process and system. Background technique [0002] There are a wide range of sources of odorous substances, mainly including: municipal sanitation and factory pollution sources. Odor substances have varying degrees of damage to the human respiratory system, circulatory system, digestive system, endocrine system, and nervous system. Therefore, odor pollution control has received more and more attention from the public and the government. "Odor Pollutant Emission Standards" (GB14554-1993) and other regulations have made regulations on the emission of odor pollutants, and the emission requirements are becoming increasingly stringent. [0003] At present, the deodorization process mainly includes: washing process, biological process, ion process, photocatalytic process, thermal oxidation process and adsorption process, and the applicable conditio...
