摘要:
常规重力流管道+提升泵站的排水方式用于乡村污水收集时，存在收集率低、建设费用高、雨污难以分流等问题。因此，管径小、布置灵活、流速快、施工对周边扰动小、可收集高浓度污水的负压排水技术更适合乡村污水收集，其改进、提升和优化上值得关注。提出了乡村负压排水的4种基本形式，即室内重力流室外负压混合收集、室内负压厕所室外负压混合收集、室内重力流室外负压分质收集、室内负压厕所室外负压分质收集，并介绍了具体案例。该案例的实践表明，负压排水技术可规模化收集高浓度黑水，为黑水的资源化利用提供了新的技术手段。
Abstract:
When the conventional drainage mode of gravity sewer combined with lifting pump station is applied in rural areas, there are problems such as low collection rate, high construction cost and difficult diversion of rainwater and sewage. Therefore, the negative pressure drainage technology is more suitable for rural sewage collection with small pipe diameter, flexible arrangement, fast flow rate, small disturbance to the periphery of construction, high concentration sewage collection. So its improvement, lifting and optimization deserve attention. Four basic patterns of rural negative pressure drainage are put forward, namely indoor gravity flow+outdoor negative pressure mixed collection, indoor negative pressure toilet+outdoor negative pressure mixed collection,indoor gravity flow+outdoor negative pressure separation collection, indoor negative pressure toilet+outdoor negative pressure separation collection, and the specific case is introduced. The practice of this case showed that the negative pressure drainage technology could collect high concentration black water on a large scale, which could provide a new technical means for the utilization of black water resources.
