Research on the Monitoring of Odor Pollution in Anaerobic Digestion Plant of Kitchen Waste
Odor pollution is one of the common environmental pollution problems in the wet waste treatment process.Taking a wet waste anaerobic treatment facility in Shanghai as an example,we carried out a study on the components,concentrations and emission characteristics of the internal workshop,the organizational emission outlet and the plant boundary in the production process of the facility.The results show that:under the deodorization measures of"front-end deodorization+end collection and treatment",the concentration of malodor pollution at the plant boundary and the emission outlet can meet the requirements of Emission Standards for Odor Pollutants(DB 31/1025-2016);the pre-processing and sorting workshop is more seriously polluted by malodors,and the characteristic factor of malodors is Total Volatile Organic Compounds(TVOCs);the odor concentration is the highest at the peak period of garbage entry and treatment.
