Ecological system for governing beheaded creek

Abstract

The invention discloses an ecological system for governing a beheaded creek. The system comprises a flow making circulating device, an ecological floating bed and plant oxidizing regions. The flow making circulating device is used for extracting and filtering and discharging water in a trunk watercourse into the beheaded creek, the ecological floating bed comprises an HDPE floating bed carrier and stain-resistant evergreen aquatic plants located in the HDPE floating bed carrier, and storm sewage ports along the beheaded creek and muddy relatively loose regions of bank slopes are plant oxidizing regions. According to the ecological system for governing the beheaded creek disclosed by the invention, the system becomes an organic ecological system by reasonably configuring the flow making circulating device, a functional ecological floating island and the plant oxidizing regions, so that the water flowability of the beheaded creek can be improved, water quality indexes of the water body are improved by three-dimensional and multi-layered biological means, and sewage entering into the beheaded creek can be governed from the source. The ecological system for governing the beheaded creek disclosed by the invention is worth being popularized.

Description

technical field [0001] The invention relates to the technical field of river water quality improvement, in particular to an ecological system for harnessing broken-headed riverbanks. Background technique [0002] Plain river network areas are generally low-lying, well-developed water systems, criss-crossing rivers, distributed in a network shape, many rivers are semi-closed shallow water bodies, the micro-environment is relatively fragile, and the water quality is very susceptible to external influences. On the one hand, the water body flows slowly or still, the water temperature is high, the evaporation is large, and the surrounding environment is heavily polluted, and the internal ecosystem of the water body is seriously damaged, which leads to the gradual increase of the nutrient concentration in the river water body, creating conditions for the massive reproduction of algae. Sufficient conditions, especially in high temperature seasons, the water body often deteriorates ...

AI Technical Summary

Problems solved by technology

On the one hand, the water body flows slowly or still, the water temperature is high, the evaporation is large, and the surrounding environment is heavily polluted, and the internal ecosystem of the water body is seriously damaged, which leads to the gradual increase of the nutrient concentration in the river water body, creating conditions for the massive reproduction of algae. Sufficient conditions, especially in high temperature seasons, the water body often deteriorates and becomes smelly in a short time; Contains many impurities such as sediment, the water quality is turbid, and the suspension is high

[0003] The current ecological restoration projects of rivers and lakes often pay more attention to the treatment of the main river, while ignoring the branches and banks of the tributaries. However, these rivers and banks with poor fluidity are usually in an anaerobic state, the water body is black and smelly, and the ecosystem damage is serious. The largest endogenous pollution that causes water quality deterioration in main rivers
