Bank slope water ecological landscape type waterfall type water quality purification system and purification method thereof

Abstract

The invention discloses a bank slope water ecological landscape type waterfall type water quality purification system and a purification method thereof, the bank slope water ecological landscape typewaterfall type water quality purification system comprises a purification slope surface and hierarchical small retaining wall steps which are arranged along a lake bank near water slope land, a solarwater supply device arranged in lake / river water, a water lifting pipeline is arranged on the solar water supply device, the water lifting pipeline is buried under the purification slope surface and is arranged along the water-facing slope of the lake bank, a plurality of water distribution pipelines are sequentially arranged below the purification slope surface and the steps of the hierarchical small retaining wall, the water inlet ends of the water distribution pipelines are communicated with the water lifting pipeline, and aquatic plants are planted on the purification slope surface. The system is simple in structure and convenient to use, and coarse sand physical filtration and aquatic plant and aquatic plant root system group biological filtration are fully utilized; the solar water pump system is used for lifting water to the platform and the filtering ditch, and gravity flow is used for saving energy and protecting environment.

Description

technical field [0001] The invention relates to the technical field of lake water quality treatment, in particular to a bank slope water ecological landscape type waterfall water purification system and a purification method thereof. Background technique [0002] In recent years, the environmental quality of surface water has been generally good, and the water quality has generally remained stable. However, from the monitoring sections of lakes and rivers, the overall situation is not optimistic. The water quality of some high-quality lakes and rivers has declined, and the water quality has dropped from Grade III to Grade IV or lower. The main impact indicators are turbidity, total phosphorus, chemical oxygen demand, and five-day biochemical oxygen demand. [0003] At present, in order to solve the problem that the water quality of lakes and rivers is not up to standard, the main measures are to control the amount of sewage discharge and allow the water body to recover from...

AI Technical Summary

Problems solved by technology

[0003] At present, in order to solve the problem that the water quality of lakes and rivers is not up to standard, the main measures are to control the amount of sewage discharge and let the water body recover from self-purification. ~10 years, at a slower pace

In addition, the lakes and rivers related to the landscape are partly greened by building floating flower bed landscapes (such as the landscape ecological floating platform structure of aquatic landscape plants disclosed by the Chinese utility model whose publication number is CN208617488U) or slope protection projects, and the water body is protected by the plant community. Biosorption and absorption of total phosphorus, nitrogen, chemical oxygen demand and five-day biochemical oxygen demand in the water, although it has a certain effect on improving the surrounding water quality and plays a role in greening and landscape, but because the water flow does not flow, Too inefficient and time-consuming

[0004] Moreover, the floating landscape devices in the prior art are only suspended on the water surface for planting, and the water purification has not realized circulation flow, and the root system of aquatic plants is well developed, which can adsorb, intercept and promote settlement of particulate nitrogen and phosphorus.

[0005] However, the purification function of the root system of aquatic plants cannot be fully utilized in the existing devices, the water purification has not realized the circulation flow, and the purification efficiency has not been fully exerted
