The invention discloses a mountain area rainwater potential energy recycling and purification and reutilization integrated system and a rainwater recycling and purifying method. The system is composed of a water diversion and desanding subsystem, a rainwater storage subsystem, a rainwater treatment unit and a rainwater power generation unit; the water diversion and desanding subsystem is formed by a water diversion canal and a sand settling pool; the rainwater storage subsystem is formed by a rainwater storage pool I and a rainwater storage pool II; the rainwater treatment unit is formed by a flocculation and sedimentation device, an ozone water treatment assembly, an ultrafiltration membrane assembly, a non-drinking water tank, a drinking water tank, a static mixer, connecting pipelines, overlfow pipes, valves and a water pump; the rainwater power generation unit is formed by a hydroelectric generator, power transmission lines and a power storage and transmission device. The system has the functions of reducing water and soil loss of small regions of a mountain area, achieving regulation and storage of the small regions of the mountain area for preventing floods, maintaining the surrounding environment, recycling the mountain area rainwater potential energy for generating power, supplying water for residents of the mountain area and achieving water supply by different quality. By means of the rainwater recycling and purifying method, the function of conducting water supply by different quality on rainwater is achieved.
Description
technical field [0001] The invention belongs to the fields of resource development, renewable resources and energy utilization, and in particular relates to a comprehensive system for recovering and purifying rainwater potential energy in mountainous areas and a method for recovering and purifying rainwater. Background technique [0002] Water is a precious fresh water resource. With the increasing shortage of water resources in the world, the development and utilization of rainwater resources has become a new way to solve the water crisis in many countries and regions. my country is rich in rainwater resources, with an annual average total precipitation of 6.2 trillion yuan and a huge amount of available rainwater resources. But on the whole, the utilization rate of rainwater resources in my country is low, and the utilization rate of natural rainfall is only 10%. Compared with other countries with high utilization rate, my country has great potential for utilization of ra...
