Evaluation Index System of Odour Pollution for Kitchen Waste Treatment Facilities in China

摘要

This paper was based on the survey of odour emission characteristics of Chinese kitchen waste treatmentfacilities and olfactory thresholds of 40 odorants which were measured by State Environmental Protection KeyLaboratory of Odor Pollution Control. An evaluation index system of odour pollution which is composed oftheoretical odour concentration, odorant indicators and theoretical odour intensity was established for kitchenwaste treatment facilities. Xining kitchen waste treatment facilities were chosen as the typical object forapplying to this system. Finally, methyl mercaptan, ethyl sulfide, sulfuretted hydrogen, ethyl alcohol, α–pinene,limonene, and dimethyl disulfide were considered as the primary indicators in this enterprise. In addition, thevalue of theoretical odour concentration and theoretical odour intensity are 59832.13 and 5. This system setup theoretical foundation for the prediction, simulation and control of odour pollution and provide technicalsupport for mastering the public impact degree of odour pollution.
