低温污水生物处理技术研究现状与展望

摘要

The efficiency of wastewater treatment decreases due to the low temperatures in the winter season in most parts of China, which results of the increase of the operation cost, and hence an adverse impact on the environment and damages to human health. The recent advances on the biological wastewater treatment technologies at low temperatures were sammanzed. In terms of the morphological types of sludge(e.g.2 floc sludge, anaerobic granular sludge and aerobic granular sludge), their advantages and disadvantages were compared and the trends on biological wastewater treatment at low temperatures were prospected.%我国绝大多数地区冬季污水处理能力降低,处理成本增加,进而影响周边环境,危害人类健康.总结了近年来国内外学者对低温污水生物处理技术的研究成果,以不同形态污泥(絮状污泥、厌氧颗粒污泥和好氧颗粒污泥)为出发点展开分析,通过对不同形态污泥的优缺点的对比,展望了低温污水生物处理技术的发展前景.
