In order to study and analyze the comprehensive benefits of pollution control engineering of livestock and poultry breeding, the comprehensive evaluation index system was protocoled according to the investigation and analysis of present situation in China. At the same time, 8 typical engineerings were used as examples. The analytical hierarchy process(AHP) and grey relational grade(GRG) analysis were used as evaluation methodology. The assessment results showed that larger scale and comprehensive engineering can achieve higher comprehensive benefits than others. Only biogas engineering used to control livestock pollution couldn't achieve ideal comprehensive benefits, because the economics of biogas engineering is very poor under the current conditions in China.
