Abstract

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