A three-dimensional integrated intelligent rain garden and its application method

Abstract

The invention discloses a three-dimensional integrated intelligent rainwater garden, which comprises a rainwater purification area, a water storage tank, a water collecting pipe, a water storage tank and an automatic control system. The invention also discloses an application method of a three-dimensional integrated intelligent rainwater garden. The rainwater purification area on the ground and the vegetation area on the roof purify the rainwater to form a three-dimensional rain garden. After the rainwater is purified, it is stored and reused to realize an integrated multi-functional rain garden. The automatic control system automatically controls the operation of the rain garden. In an emergency, the working mode can be controlled through the on-site control terminal. When unattended, the working mode can also be remotely controlled through the remote control terminal to create an intelligent The optimized rain garden helps the construction of smart cities.

Description

technical field [0001] The invention relates to the field of environmental engineering, more specifically, it relates to a three-dimensional integrated energy intelligent rainwater garden. Background technique [0002] Rainwater is an important link in the urban water cycle system, which plays a key role in regulating and supplementing regional water resources and improving the ecological environment. With the rapid promotion of urbanization, the urban form has undergone tremendous changes due to the transformation of land use patterns and the replacement of hardened surfaces with natural surfaces, and the problem of urban rainwater has become more and more prominent. Urban non-point source pollution caused by rainstorm runoff has already aroused the great attention of the international community. Rain gardens emerged as a municipal landscape technique to address stormwater runoff. Rain garden is an effective natural rainwater purification and disposal technology, and it i...

Problems solved by technology

[0004] However, for many rainy areas, due to the large amount of rainfall and the large amount of organic pollutants contained in the rainwater runoff, the runoff velocity is relatively large, and the scouring effect is obvious.

When a large amount of rainwater runoff enters the rain garden, the filtration capacity of the rain garden is limited, resulting in a decrease in flow velocity, an increase in water flow resistance, and sedimentation and retention in the rain garden. Over time, it will lead to a decrease in the water purification and absorption capacity of the rain garden, which is not conducive to rainwater Timely elimination and effective use of
