渭河流域陕西段城镇污水处理厂提标改造状况调查与问题分析

Investigation and Analysis of Condition of Municipal Sewage Plants in Shaanxi section of Wei River Basin

在渭河流域陕西段60家城镇污水处理厂现场调查与资料收集基础上,通过对13家污水处理厂年达标率的计算与分析,最后认为在提标改造中应将重点放在SS与TP的去除2个方面。此外,还对该区域现有污水处理工艺提标改造措施(低碳源、低SS达标率、低温以及强化脱氮除磷的采取措施)进行了归纳总结与深入分析。针对调研发现问题,提出了相应建议。

Based on filed survey of 60 municipal sewage plants in Shaanxi section of Weihe River basin and the gathering of the related data, the calculation and analysis of the annual qualified rates were made. It was suggested that the SS and TP should be focused on in the project of upgrading and reconstruction. Besides, the measures of the project of upgrading and reconstruction（including low carbon sources, low SS standard-reaching rate, low temperature and the measures taken to enhance the removal of nitrogen and phosphorous） in this area were summarized and deeply analyzed. Aiming at the problems found in the investigation, related suggestions were made.
