辽河源农村生活污水治理方法与技术研究

Study on Treatment Methods and Technologies of Rural Domestic Sewage in the Sources of Liaohe River Sewage in the Sources of Liao River

随着我国经济的发展与社会的进步,在农村居民的生活水平不断提高的同时其生活用水量和排放量也随之增加,且绝大部分污水未经任何处理直接随意排放,因而造成所在区域环境污染,采用合理可行的治理方法与技术是解决问题的关键所在。结合农村的特点,对辽河源的农村生活污水处理方法与工艺进行了分析论述,给出了辽河源区域内农村生活污水处理方法和技术。辽河源头区水污染综合治理技术及示范研究课题是采用农村生活污水处理小型微动力设备,通过气浮装置的预处理,实现部分污染物,特别是浮游、轻油油脂成分的降低,在气浮过程中,适量投加絮凝药剂,使之聚集移除。为保证处理效果的优化,将在尾水部分建设小型生态沟渠,以期达到更好的处理效果。可为减少其他农村地区的生活污水随意排放、污水治理提供可借鉴的方法与技术。

With the development of China’s economy and social progress,the living standards of rural residents are constantly improving,while the domestic water consumption and volume of rural residents are increasing,and most of the sewage is discharged directly and randomly without any treatment,thus causing environmental pollution in the region.The key to be solved is to adopt reasonable and feasible treatment methods and technologies.In this paper,combined with the characteristics of rural areas,the rural domestic sewage treatment methods and technologies in the source region of the Liao River are analyzed and discussed,which can provide reference methods and technologies for reducing the random discharge of domestic sewage and sewage treatment in other rural areas.The research topic of comprehensive water pollution control technology and demonstration in the headwater area of Liaohe River is to adopt small micro-power equipment for rural domestic sewage treatment,and realize the reduction of some pollutants,especially floating and light oil and fat components,by pretreatment of air floatation device.In the process of air floatation,a proper amount of flocculating agent is added to aggregate and remove them.In order to ensure the optimization of treatment effect,a small ecological ditch will be built in the tail water to achieve better treatment effects.
