A system for collecting and reprocessing rainwater

Abstract

A rainwater collection, reprocessing and utilization system includes a rainwater collection device and a rainwater reprocessing and utilization device; the rainwater collection device collects rainwater into a first water collection tank (6), and the water inlet pipe (B3) of the rainwater reprocessing and utilization device is connected to The first water collection tank (6), the rainwater collected by the first water collection box (6) enters the rainwater reprocessing and utilization device through the water inlet pipe (B3). The rainwater collection device can collect the rainwater collected on the roof in layers, which is convenient for users on each floor. Drainage is difficult. The rainwater reprocessing utilization device can automatically add medicine while adding water, and automatically turn off the medicine after adding water, which can effectively improve the quality of rainwater purification and reduce labor intensity.

Description

technical field [0001] The invention relates to the technical field of sponge cities, in particular to a system for collecting, reprocessing and utilizing rainwater. Background technique [0002] Sponge city refers to a city that can be like a sponge and has good "elasticity" in adapting to environmental changes and responding to natural disasters. Utilization, the construction of sponge cities should follow the principles of ecological priority, combine natural methods with artificial measures, and ensure the safety of urban drainage and waterlogging, maximize the accumulation, infiltration and purification of rainwater in urban areas, and promote rainwater resources. utilization and ecological environment protection. There are currently some rainwater harvesting facilities. [0003] After searching, it is found that the invention of patent No. CN201610619621.7 provides a rainwater collection and treatment system. The system includes a water diversion system, a rainwater ...

Problems solved by technology

[0009] However, problem 1: the existing buildings collect water on the roof through the parapet, and then drain it to the ground through the drain holes and drain pipes opened on the side or to the ground-mounted cisterns. Although this method can reduce rainwater However, if users on higher floors need to use water for watering flowers or other purposes, they need to re-add pipes to pump them up from the bottom reservoir, which increases the cost

[0010] Problem 2: In the process of rainwater collection and treatment, it is often necessary to use rainwater purification equipment. At present, the general rainwater purification equipment often cannot realize the automatic dosing function during purification. Adding different proportions of medicines, it is difficult to master this proportion when adding medicines manually, resulting in a decrease in the quality of purification
