农村生活污水处理技术模式的层次分析研究

Analytic Hierarchy Process of Techniques in Rural Domestic Sewage Treatment

在当前农村环境的治理中,生活污水处理技术和模式一直是农村环保不断探索的问题。根据农村实际情况选择合适的处理技术显得尤为重要。通过实地调研,对农村生活污水产生现状、常见处理工艺进行了分析。根据当前实际应用情况,选定了四种典型农村生活污水技术模式,以及对模式选择有影响的六个主要因素,按照层次分析法进行了研究,以期为农村生活污水处理工艺的选择提供参考。分析结果表明首选方案为"A/O+人工湿地"处理技术,与目前农村生活污水实际状况相吻合。

In current rural environmental treatment,it has always been a continuously issue in seeking for rural domestic sewage treatment technology and mode. It is especially important to select an appropriate treatment technology according to rural actually situation. Through field investigation,current status of rural domestic sewage and common treatment techniques were analyzed. On the base of investigation,six influential factors in selection of techniques were chosen to study by analytic hierarchy process. This work will provide a reference on selection of rural domestic sewage treatment technology.
