Abstract

The invention provides a self-purification type rainwater harvesting cistern system suitable for a rural area. The system is suitable for being built at a low-lying terrain and comprises a reservoir, a water collecting tank, a filter layer, a vegetation system and a collection system, wherein a cover is arranged at the top of the reservoir; the water collecting tank is arranged around the reservoir; the elevation of the water collecting tank is lower than the elevation of surrounding ground surface; the filter layer fills the interior of the water collecting tank; the vegetation system is planted at the top of the filter layer; the collection system is provided with a collecting pipe which is communicated with the water collecting tank and the reservoir. The self-purification type rainwater harvesting cistern system has a rainfall runoff water quality purification function under the condition of no power and no guard, the water quality of a rainwater collection cistern is greatly improved, and the self-purification type rainwater harvesting cistern system has the advantages that the structure is simple, the cost is low, the remoulding is easy and the like.

Description

technical field [0001] The invention relates to a water quality non-powered purification technology for rural rainwater cellars, and belongs to the technical field of water treatment. Background technique [0002] After the rainwater falls to the ground, surface sediment pollutants enter the rainwater runoff, resulting in aggravated rainwater runoff pollution. Natural conditions such as geography and environment have a direct impact on the pollution load of rainwater runoff. With the increase of rainfall interval and air pollution load, the quality of runoff water will decline, which will have a serious impact on the water quality of water cellars. Conventional rainwater cellars only perform the function of collecting rainwater runoff and cannot realize simultaneous water purification. Therefore, the overall quality of rainwater collected in water cellars is poor, and various diseases caused by it continue to rise, restricting the sustainable use of rainwater resources. Wa...
