不同区域农村生活污水处理技术层次分析——以新疆维吾尔自治区为例

The AHP about Rural Domestic Sewage Treatment Techniques in Different Regions:Taking Xinjiang Uygur Autonomous Region as An Example

在对新疆维吾尔自治区(以下简称“新疆”)农村生活污水排污特点、处理现状和常见处理工艺进行调研的基础上,根据新疆农村生活污水处理排放标准要求,筛选了满足标准要求的5种组合处理技术。根据自然环境条件、人口规模和聚集程度、居民生活习惯、经济发展水平、污水收集方式、处理规模和排水水质要求等,将新疆农村分成3类区域。综合考虑排放去向、处理规模、处理效果、处理方式、投资运行成本5个主要影响因素,分区域对5种组合处理技术进行了层次分析,得出3类区域的农村生活污水处理模式优选顺序,以此可为新疆农村生活污水处理规范化管理和技术选择提供参考。

Based on the investigation of the discharge characteristics,treatment status and common treatment process of rural domestic sewage in Xinjiang Uygur Autonomous Region(Xinjiang),and according to the discharge standard requirements of rural domestic sewage in Xinjiang,five combined treatment technologies meeting the standard requirements are selected.In addition,according to natural environment conditions,population scale and aggregation degree,residents′living habits,economic development level,sewage collection,treatment scale and drainage water quality requirements,Xinjiang is divided into three types of regions.Five main factors such as discharge direction,treatment scale,treatment effect,treatment method,investment and operation cost are comprehensively considered to analyze hierarchically five combined processing techniques in different regions,and the optimal sequence of rural domestic sewage treatment modes in three types of regions was obtained,which will provide references for standardized management and technologies choice of rural domestic sewage treatment in Xinjiang.
