Description

technical field

[0001] The invention relates to a cyclone rainwater collection and reuse integrated device, which belongs to the technical field of rainwater collection devices. Background technique

[0002] With the continuous development of economy and rapid population growth, the demand for water supply in industry, agriculture and life is constantly escalating. Human beings are facing more and more serious threats of water shortage, water body deterioration and environmental pollution. Water crisis has become a global issue. One of the hot issues. my country's water resources rank 6th, but the per capita water resources are only 2400-2500m 3 , is less than 1 / 4 of the world average level, and the average water volume of cultivated land is only 4 / 5 of the world average level, and the distribution of water resources is uneven. Many cities in our country are in a state of water shortage, and rainwater, as a long-term and stable non-traditional water source, is easy to obta...
