Green low-carbon ecological water purification system for river embankment

Abstract

The invention provides a green low-carbon ecological water purification system for a river embankment, and relates to the technical field of water environment governance. The green low-carbon ecological water purification system comprises an ecological filter dam, a water storage tank and an ecological pond which are connected in sequence, the ecological filter dam is piled into a step shape by different filler layers, water flow in a dam body is in a baffling type by designing the position of an overflow port in the step-shaped dam body, and plant boards are placed at the top of the dam body for planting plants; a pipeline is arranged at the bottom of the water storage tank and is connected with the bottom of the ecological pond; and plant floating plates and biological ropes are hung in water in the ecological pond, and a plant buffer strip is arranged outside the ecological pond. Low-lying pools and ponds of a riverway ecological system are fully utilized, the front end of the stepped filter dam serves as a riverbank dam, and water drops at the rear end of the stepped filter dam supplement dissolved oxygen in a water body; water enters the ecological pond from the bottom to solve the problem of stagnant water at the pond bottom, and quick drainage of the river in the wet season and direct water supplementation of the river in the dry season can be achieved through pipeline arrangement; and according to the system, a water body automatically flows and is subjected to drop aeration, the water body is purified in a green and low-carbon mode, and meanwhile the landscape effect is achieved.

Description

Technical field [0001] The present invention relates to the field of water environmental governance, and in particular to a green low-carbon ecological water purification system for river embankment. Background technique [0002] In recent years, the urbanization of townships has developed at the same time, and the increasing domestic sewage, industrial wastewater, and early rain water have gradually weakened the river, and even the original self-net capacity. The concentration of various pollution substances in the water increases, resulting in deterioration of water quality. The life of surrounding residents has caused serious impact, especially in the rainy season. [0003] There is a large and small lant pond on both sides of the township river, which is in drought or dead water. It is used to use the advantage of the earth to design bypass ecological governance system. It can not only purify the river water body, but also beautify the surrounding landscape around the river, ...

AI Technical Summary

Problems solved by technology

[0004] Ecological filter dams have attracted attention because they can purify river water in situ. Due to the limited volume of the dam body, the contact time between pollutants and filter materials is short, and the effect of improving water quality is not ideal. In addition, plants are generally planted on the top of ecological filter dams. When the water level is low, the plants cannot contact the water body and it is difficult to perform the pollutant interception function. Long-term water shortage will also cause the plants to dry up and die, making management more difficult.
