A rainwater collection and reuse system for urban parks

Abstract

The invention relates to a rainwater collection and reuse system in an urban park, which comprises a rainwater collection pool (1), a power water tower (6), a disinfection pool (9) and a water storage pool (15); a rainwater collection pool (1) 1) The outlet of the rainwater collection tank is provided, the middle and upper part of the power water tower (6) is provided with a control door (5) that is in fluid communication with the outlet of the rainwater collection tank, the lower part is provided with the outlet of the power water tower, and the disinfection tank (9) is provided with the power water tower. A regulating door (18) in fluid communication with the outlet of the sterilization tank and the reservoir (15) is provided with a reservoir inlet in fluid communication with the outlet of the sterilization tank. The beneficial effects of the invention are: the interception of pollutants such as soil, sand and gravel in rainwater is realized by the sludge baffle, the use of a large number of treatment equipment such as grilles is omitted, and the construction cost of the system is reduced; the stirring fan is driven by natural wind power. Rainwater and disinfection reagents are stirred in the disinfection tank to reduce the power cost of system operation.

Description

technical field [0001] The invention relates to a rainwater collection and reuse technology, in particular to a city park rainwater collection and reuse system. Background technique [0002] Water is the source of life and an important natural and strategic resource. Since human history, water has been a necessary condition for the survival of human beings and ecosystems, and has always played a vital role in the development of human society. But as we all know, with the development of economy, the growth of population and the continuous improvement of people's material and cultural living standards, the demand for water resources around the world is also increasing. All kinds of contradictions are becoming more and more serious. The United Nations pointed out in the 1997 report "Comprehensive Evaluation of the World's Fresh Water Resources": "The problem of water shortage will seriously restrict the economic and social development in the 21st century, and may lead to conf...

Problems solved by technology

[0006] The traditional rainwater collection and treatment system must rely on external power in the rainwater collection and purification process alone. In the rainwater decontamination and purification process, a large number of decontamination hardware equipment needs to be designed and used, and the operating cost of the system is relatively high.
