Energy-saving and water-saving multifunctional water conservancy ecological complex and application thereof

Abstract

The invention discloses an energy-saving and water-saving multifunctional water conservancy ecological complex and application thereof. The energy-saving and water-saving multifunctional water conservancy ecological complex comprises an underground part and an overground part, and the underground part comprises an underground regulation and storage system, an underground water purification systemand a recycling system; the overground part comprises an overground ecological park, an overground urban building and an urban lake inland river; the underground regulation and storage system collectssurface runoff rainwater and domestic sewage, regulates and stores the surface runoff rainwater and the domestic sewage and sends the treated sewage to the underground water purification system; theunderground water purification system purifies sewage sent by the underground regulation and storage system and sends purified water to the overground ecological park, the overground urban building and the urban inner lake inland river, and the combined ecological floating island and the river and lake water ecological purification platform are installed in the urban inner lake inland river. According to the invention, urban rain sewage area regulation and storage and distributed on-site treatment can be effectively carried out, the functions of flood drainage, pollution control, water saving,energy saving, ecology, economy, beautification and science popularization are integrated, and a leisure and comfortable working and living environment is provided for surrounding residents.

Description

technical field [0001] The invention belongs to the field of water treatment and application, in particular to an energy-saving and water-saving multifunctional water conservancy ecological complex and its application. Background technique [0002] At present, there is no urban ecological complex integrating drainage, pollution control, water saving, energy saving, ecology, economy, beautification, and popular science in China. The current sewage treatment ecosystem is generally divided into: [0003] 1. The sewage treatment plant itself only has the function of sewage treatment, without other derivative functions such as water-saving, energy-saving and ecological science popularization. The form is single and wastes urban land; [0004] 2. The current urban artificial wetlands are generally only used for tail water standardization, and the viewing degree is poor. They are not open to the outside world, wasting wetland resources, and cannot perform multiple functions such as...

AI Technical Summary

Problems solved by technology

[0003] 1. The sewage treatment plant itself only has the function of sewage treatment, without other derivative functions such as water-saving, energy-saving and ecological science popularization. The form is single and wastes urban land;

[0004] 2. The current urban artificial wetlands are generally only used for tail water standardization, and the viewing degree is poor. They are not open to the outside world, wasting wetland resources, and cannot perform multiple functions such as ecological landscape and reclaimed water reuse;

[0005] 3. In the current landscape parks and wetland parks in the suburbs of cities and towns, ecological wetlands are only used as landscape ornamental functions, taking into account some water purification functions, without functions such as regulation and storage, sewage treatment, reclaimed water reuse, science and education;

[0006] 4. The tail water reuse process of centralized sewage treatment plants is long, and it is difficult to reuse upstream urban rivers at low cost, and decentralized sewage treatment is a better solution;

[0007] 5. Urban waterlogging is discharged through the rainwater pumping station. Due to the serious pollution of the initial rainwater, the waterlogging also causes the river to become black and smelly
