摘要
从共基质条件下的微生物降解处理、厌氧好氧发酵工艺、固定化生物催化剂技术、膜生物反应器以及基因工程技术等方面综述处理难降解有机污染物的降解原理及研究进展。认为目前对难降解有机污染物的生物处理存在的关键问题是技术不够成熟,降解效率还不高。提出今后应该在筛选高效降解菌及基因工程菌,探明高效降解菌株的代谢动力学和代谢机理,创建新的技术手段和多种技术的联合使用,将现有的技术成果转化为实用技术等方面进行深入的研究。
Reviewing the usage of the biodegradation of refractory organic pollutants,including the biodegradation activities under co-substrates conditions, the application of anaerobic-aerobic treatment process, the usage of immobilized microbial cells technology, the appliance of membrane biological reactor and the usage of genetic engineering technology, the principles and advances of these technologies were discussed. Unripe technology and low degradation efficiency is the vital problem to deal with the refractory organic pollutant recently. It shows that we should make further researches of screening high efficiency degradation bacterium and gene engineering bacterium, exploring metabolism kinetic and mechanism of high efficiency degradation bacterium, establishing new means combined with the other technology to convert the existing technology into practice.
