农村牧区生活污水处理技术选择适用性评价

Evaluation on the Applicability of Domestic Sewage Treatment Technology Selection in Rural and Pastoral Areas of Inner Mongolia

生活污水排放是农村牧区湖泊和河流水体富营养化的主要原因之一,为推进农村牧区污水治理,依据各地区地理环境及经济条件,科学有效地进行污水处理技术方案的技术性、经济性、可靠性的比选十分重要。结合内蒙古自治区农村牧区环境、经济和社会条件,以常用污水处理技术为研究对象,以综合指数评价法为基础,构建了结合技术自身通用性评价和根据不同地区特点进行匹配性评价的污水处理技术适用性评价指标体系,分东、中、西部进行了农村牧区生活污水处理的8种技术适用性评价。结果表明:根据内蒙古自治区各盟市自然环境和经济条件,Engelbart SST一体化设备、序批式生物反应器(SBR)和人工湿地是目前综合适用性较好的技术。

Domestic sewage discharge has become one of the leading causes of environmental pollution in rural and pastoral areas.In order to promote sewage treatment in rural and rustic regions,according to the different geographical environments and economic conditions of other sites,it is essential to compare and select each scheme scientifically and effectively in terms of technology,economy,and reliability.This study combined with the environmental,economic,and social conditions of rural and pastoral areas in Inner Mongolia,took the commonly used wastewater treatment technology as the object,and built a wastewater treatment technology applicability evaluation system based on the comprehensive index evaluation method,which combined with the evaluation of the generality of the technology itself and the matching correc⁃tion according to the characteristics of different regions.The applicability of 8 technologies for domestic sewage treatment in rural and pastoral areas was evaluated.The results show that according to the natural environment and economic conditions of each municipality in Inner Mongo⁃lia Autonomous Region,Engelbart SST integrated equipment,sequencing batch bioreactor(SBR),and constructed wetland are the technolo⁃gies with good comprehensive adaptability at present.
