Abstract
The invention discloses a rainwater garden circulating system which comprises a purified water storage chamber, a rainwater garden system and a central water tank system, wherein rainwater passes through aquatic plants and a planting soil layer in sequence to primarily filter large granular impurities in rainwater; then the rainwater flows into a gravel drainage layer for further secondary filtration, flows into a purification filter layer for deep automatic adsorption and purification of the rainwater, and flows into a purified water storage chamber through solid-waste permeable concrete; meanwhile, rainwater is primarily filtered by the surface plants and the solid waste permeable bricks, then is secondarily adsorbed and purified by the nutrient soil layer and the purification filter layer, and flows into the purified water storage chamber through the solid waste concrete layer; the water collecting device is arranged in the water purifying and storing chamber and is connected with the plant irrigation spray head to guide water to the plants on the ground surface. The invention can effectively adsorb and filter garbage, organic pollutants and heavy metals in the rainwater runoff, and plays a good role in reducing pollution of sponge cities and controlling the rainwater runoff.
Description
Technical Field
The invention relates to a rainwater circulation system, in particular to a rainwater garden circulation system.
Background
The sponge city is a new generation of urban rainfall flood management concept, which means that the city can be like a sponge, has good elasticity in the aspects of adapting to environmental changes and coping with natural disasters caused by rainwater, and can also be called as a water elasticity city, wherein a rainwater garden is the most typical product in the sponge city, is a naturally formed or artificially excavated shallow-concave greenbelt, is used for gathering and absorbing rainwater from a roof or the ground, purifies the rainwater through the comprehensive action of plants and sandy soil, and gradually infiltrates soil to contain underground water or replenish urban water such as landscape water and toilet water, and is an ecologically sustainable rainfall flood control and rainwater utilization facility. The sponge city has good adjusting capacity in the aspects of coping with natural disasters, adapting to environmental changes and the like a sponge, mainly solves the problems of urban waterlogging, urban water environment deterioration and the like, realizes the protection and utilization of drinking water sources, sewage, ecological water, natural rainfall, surface water, underground water and the like, fully considers the water resources, the water environment, the water ecology and the water safety, and ensures that the social water circulation can be communicated with the natural water circulation.
In recent years, the improvement of the concept of sponge cities solves many problems in urbanization construction, but does not completely solve the problems. Foreign sponge concepts are mainly urban development and design which mainly aim at rainwater runoff management, rainwater collection, landscaping and the like for solving urban rainstorm flood. The common black and odorous water body and water resource shortage phenomena still exist, and the problems have certain obstruction to the urbanization construction and influence the life quality of people. At present, China faces a specific development period, and sponge city construction is in line with the national conditions of China. In order to provide a better living environment, the basic meaning provided by the sponge city concept is researched and is completely integrated into city construction, so that the rapid development of the city construction can be realized.
Currently, sponge city construction faces many problems, for example, the sponge city construction is not a small-scale construction due to insufficient overall coordination, and the involved site has small areas, road surfaces, landscaping and water systems. The filtration of water resources is not thorough and can not reach the corresponding standard, and the like; sponge city construction is not a single design concept, and the comprehensive performance is relatively strong and has certain innovation.
