The phenomenon of dead pigs floating on the Huangpu River has sparked peoples attention and concern about safe disposal of dead livestock and poultry. Currently, there are still a lot of problems existing in the disposal of dead livestock and poultry in China, such as insufficient numbers of harmless treating pool, single technology, serious secondary pollution, lack of compensation mechanisms, etc.. This paper summarized the harmless disposal methods of dead livestock and poultry, and existing problems in these treatments. The paper also systematically sumsed up the theory of aerobic fermentation technology for treating dead livestock and poultry, and researched status and progress at home and abroad. The authors suggested that China should learn from foreign experience, promote the aerobic fermentation technology, carry out studies on optimizing dead livestock and poultry aerobic fermentation technology, and on controlling harmful gas, etc. At the same time, the paper suggested the rational selection of dead livestock and poultry harmless treatment methods, and to adopt comprehensive measures according to local conditions.

Key words: dead livestock and poultry, harmless disposal, aerobic fermentation
