高原农村生活污水处理技术进展

Development of Rural Domestic Sewage Treatment Technology in Plateau Region

由于高原地区存在低温和低氧的自然特征,因此采用传统污水处理工艺时会因微生物活性下降导致高原地区农村生活污水处理达不到排放标准。针对高原地区独特的气候特性,目前已开发了多种可适用于高原地区农村生活污水的处理技术,如:人工湿地、地下渗滤和生态大棚污水处理系统。尽管上述处理技术能有效地缓解低温和低氧带来的问题,但仍不能完全适用于高原地区。因此,针对现有研究的不足及高原地区污水处理面临的问题,本文对未来高原地区农村生活污水处理技术的发展方向提出了可行的建议。

Due to natural characteristics of low temperature and low oxygen in plateau areas,the treatment effect of the traditional sewage treatment process on the rural domestic sewage in plateau aresa did not meet the discharge standards.According to the unique climatic characteristics of plateau areas,a variety of treatment technologies for rural domestic sewage in plateau areas have been developed,such as constructed wetlands,underground infiltration and ecological greenhouse sewage treatment systems.Although the above treatment techniques can effectively alleviate problems caused by low temperature and hypoxia,they are still not fully applicable to plateau areas.Therefore,in view of the shortcomings of existing research and problems faced by sewage treatment in plateau areas,this paper puts forward feasible suggestions for the development direction of rural domestic sewage treatment technology in plateau areas in the future.
