城镇生活污水处理技术研究进展

随着城市化的发展和人民生活水平的提高，城镇生活污水排放数量大，呈逐年增长趋势，且污水成分日趋复杂，是导致水体环境恶化的重要污染源，城镇生活污水迫切需要治理，本文在对实施城镇生活污水处理难点进行概述的基础上，就近年来采用生物法、膜分离技术和强化一级处理工艺处理城镇生活污水的研究进展、优势和局限性进行了较为系统的分析，探讨了城镇生活污水处理技术的发展方向。

Advances in Treatment Technology of Urban Domestic Wastewater

With the development of urbanization and the improvement of people's living levels,there is more and more urban wastewater which is discharged into the environment at a high increasingly rate.The composition of domestic wastewater is also becoming increasingly complicated.As an important pollution source of aquatic environment deterioration,Municipal effluent is to be treated urgently.Based on the summarization of difficulties in implementing urban domestic wastewater,recent advances,advantages and limitations of wastewater treatment technology including the biological treatment,membrane separation and the intensified primary treatment were systematically analyzed.In addition,the developing directions of the techniques in treating municipal wastewater were discussed.
