A high water content two-way flow sponge type wetland rainwater purification, regulation, storage and reuse system

Abstract

The invention discloses a high water content bidirectional flow sponge type wetland rainwater purification, storage and recycling system, comprising a grid well, a rainwater purification rubble filter, an aeration adjustment tank, a hydrolysis acidification tank, a contact oxidation tank, a storage adjustment unit and a In the two-way flow wetland purification system, a rainwater purification rubble filter, an aeration adjustment tank, a hydrolysis acidification tank and a contact oxidation tank are arranged in sequence below the grid well, and the aeration adjustment tank is communicated with the hydrolysis acidification tank through the first drainage port, The hydrolysis and acidification tank is communicated with the contact oxidation tank through the second drain, the contact oxidation tank is connected to the regulation and storage unit through the opening, and the rainwater enters the regulation and storage unit through the opening. The flow wetland purification system penetrates into the storage unit for storage. The two-way flow wetland purification system is composed of a pebble support layer, a wetland matrix layer, a reinforcement net and wetland plants. The invention realizes rainwater regulation and storage and ecological purification, can save water resources, reduce energy consumption, and achieve rainwater recycling.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a high water content two-way flow sponge type wetland rainwater purification, regulation, storage and reuse system. Background technique [0002] Many cities in my country are facing frequent flood disasters and water shortages. The sponge-type wetland technology integrates "sponge city" and the latest rain and flood management concepts at home and abroad, and uses sponge-type wetlands to prevent waterlogging and purify rainwater, so as to realize the utilization of rainwater resources and beautify environment. [0003] The well-known sponge-type wetland is an ordinary naturally sunken wetland, which has the ability of natural accumulation, natural infiltration, and natural purification of rainwater, but the ordinary natural subsidence wetland lacks pretreatment of rainwater, which is likely to cause wetland blockage and reduce rainwater storage. At the same time, the wate...

AI Technical Summary

Problems solved by technology

[0003] The well-known sponge-type wetland is an ordinary naturally sunken wetland, which has the ability of natural accumulation, natural infiltration, and natural purification of rainwater, but the ordinary natural subsidence wetland lacks pretreatment of rainwater, which is likely to cause wetland blockage and reduce rainwater storage. At the same time, the water holding capacity of ordinary wetlands depends on the area of ​​wetlands. When the area of ​​wetlands is limited, the storage capacity will be greatly reduced. Moreover, such a system has no reuse space and cannot realize rainwater reuse.
