A green low-carbon ecological water purification system for river embankments

Abstract

The green and low-carbon ecological water purification system for river embankments provided by the present invention relates to the technical field of water environment treatment, and includes ecological filter dams, water storage tanks and ecological ponds connected in sequence. The position of the overflow outlet inside the dam body makes the water flow inside the dam body baffled, and plant boards are placed on the top of the dam body to grow plants; the water storage tank is provided with stilling sills and tail sills, and the bottom is provided with pipes connected to the bottom of the ecological pond; inside the ecological pond The water body is suspended with plant floating boards and biological ropes, and a plant buffer zone is arranged outside; the present invention makes full use of the low-lying pits and ponds of the river ecosystem, the front end of the stepped filter dam acts as a river bank dam, and the water drops at the rear end to supplement the dissolved oxygen in the water body; the ecological pond from the bottom The water inlet solves the problem of stagnant water at the bottom of the pond, and the pipeline layout can realize rapid drainage of the river during the wet season, and direct replenishment of the river during the dry season; in the present invention, the water body of the system flows by itself, and the water is aerated by falling water, and the water body is purified in a green and low-carbon way, and at the same time, the landscape effect.

Description

technical field [0001] The invention relates to the technical field of water environment treatment, in particular to a green low-carbon ecological water purification system for river embankments. Background technique [0002] In recent years, with the rapid development of township urbanization, the increasing domestic sewage, industrial wastewater and initial rainwater have gradually weakened or even lost the original self-purification ability of the river, and the concentration of various pollutants in the water body has increased, causing water quality to deteriorate. The life of surrounding residents is seriously affected, especially in the rainy season. [0003] There are large and small abandoned low-lying pits and ponds on both sides of the river in towns and villages, which are in a state of drought or stagnant water all year round. Taking advantage of the terrain difference to design a bypass ecological management system can not only purify the water body of the rive...

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.
