Problems solved by technology
Studies have shown that the pollutant content of roof rainwater is relatively low. If pure biological treatment is used, due to poor biodegradability, it is rarely used at present; if pure physical or chemical treatment is used, the cost is relatively high, and there will be secondary pollution risks of

Embodiment Construction
[0052] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.
[0053] In the traditional rainwater purification device, the rainwater generally directly enters the planting layer, which has a strong impact on the soil of the planting layer. In the present invention, the rainwater first enters the storage tank, removes large particle sediment and large particle size suspended matter, and then enters the The vertical flow sedimentation tank of the mobile roof rainwater ecological purification system can not only remove particulate matter, but also reduce the impact of...

Abstract
The invention provides a movable roof rainwater ecological purification system which comprises an ecological purification treatment device and a movable facility. The ecological purification treatment device comprises a vertical-flow sedimentation tank and a packed bed; the vertical-flow sedimentation tank is embedded in the packed bed; outlet water is guided to the packed bed from the upper portion of the vertical-flow sedimentation tank by a water distribution pipe. The movable roof rainwater ecological purification system has the advantages that rainwater can flow into the vertical-flow sedimentation tank of the movable roof rainwater ecological purification system, accordingly, particulate matters can be removed, and impact of the rainwater on planting layers can be reduced; the water can uniformly flow into the packed bed after being distributed by the water distribution pipe and is purified by multiple layers, and accordingly the quality of outlet water can be ultimately improved.
Description
technical field [0001] The invention relates to the field of rainwater ecological purification, in particular to a mobile roof rainwater ecological purification system. Background technique [0002] Roof rainwater is a water resource with relatively low pollutant content. After purification, it can be used as miscellaneous water for urban life or even drinking water. In addition to being used for irrigation and replenishing groundwater, it can also be used for landscape environment, greening, water for car washes, and roads. Flushing, cooling water replenishment, toilet flushing, etc. For areas with less annual rainfall, the purification and reuse of roof rainwater can save water resources and greatly alleviate the problem of water shortage. For areas with a lot of rainfall, the purification treatment of roof rainwater is of great significance to reduce the pollution of rainwater to the environment. [0003] The collection and treatment of rainwater mainly includes four as...
