北京理工大学珠海学院2020届本科生毕业设计Design of Waste Gas Treatmentfor Pig Farm in Qingyuan City,Guangdong ProvinceAbstractAccording to the production and characteristics of waste gas from variouspig farms in China,the present situation and common problems in the treatment of commonfeces in pig farms in China are analyzed and summarized.The NHs and H2S.produced inbiogas were treated by "UASB anaerobic digestion of manure and treatment of iron oxideby dry desulfurization process"The HS emission standards of air pollutants in farmsare 0.06 mg /m,NH after consulting the GB18596-2001>of emission standards of wastegas pollutants and the Standard of emission of odor pollutants (GB14554-93)3 Emissionstandards 1.5 mg /m.this design uses the "USAB limestone/wet desulfurization"process to treat NH3,H2S and other harmful gases in biogas produced by anaerobicdigestion,which requires the final treated exhaust gas to meet this standard.Keywords:pig farm manure;anaerobic digestion;waste gastreatment;limestone/gypsum wet desulfurization-2-
