Study Progress of Biodegradability

Biodegradability , are known as biological degradation degree of biodegradable organic pollutants by microorganisms. Organic biodegradability can be divided into aerobic biodegradability and anaerobic biodegradability. At present, evaluation methods for biological degradation degree include aerobic biodegradability method of relative oxygen consumption or rate method, integrated test evaluation method and water quality index evaluation; evaluation anaerobic biodegradability include CH4 gas production method, CO2 gas production method, gas production method and COD synthesis method. In this paper the aerobic biodegradability and anaerobic biodegradability evaluation method are commended, and appraise biodegradability methods for next research.
