Abstract: Composting technology is an important way for the harmless treatment of chicken manure,but the waste gas produced in the composting process has adverse effects on the composting quality,and causes harm to the ecological environment and human health.Therefore,the control technology of the waste gas produced by chicken manure composting is one of the restrictive factors for the development of composting technology.These exhaust gases often have complex components,and heavy smell,the exhaust gas containing both nitrogen and sulfur is the key research subject,including NH3,NOX,H2S,and VOCS of nitrogen and sulfur-containing alcohols,ketones,ethers,etc.The paper introduced the production mechanism of the specific components of the exhaust gas,the relationship between the law of the emission intensity and the properties of chicken manure,composting environment and process conditions was briefly described,reduce or removing exhaust gas emissions from compost by optimizing composting process conditions (temperature,oxygen content,pH,carbon-nitrogen ratio and water content),biological methods (adding microbial agents,biofilter and biological combined compost),regulators (adding biochar and other additives) and end technology.Reviewing the academic research achievements of scholars at home and abroad in recent years,analyzing the removal effect of different exhaust gas and the problems in practical application.The prospect of the future production practice was discussed,in order to provide a reference for the waste gas control research in the process of chicken manure and other waste composting.

Key words: chicken manure compost; compost waste gas; ammonia; hydrogen sulfide; volatile organic compounds
