Ecological dredging handling method for riverways or lakes

Abstract

The invention discloses an ecological dredging handling method for riverways or lakes. The method comprises the steps that firstly, bottom mud excavation and drying handling are performed; secondly, a supporting layer, a transition layer, a reaction layer and a safety coverage layer are sequentially arranged on a riverbed upwards after bottom mud dredging is performed, and a river bottom biological membrane recovery system is formed; and thirdly, the river bank and a river levee are handled to form an ecological bank protection system. According to the riverway water ecological system, under the background that bottom mud is polluted, an ecological recovery project implemented according to the development ecological theory is applied, and the method essentially achieves the purpose of sustainably-developing ecological niche recovery for the riverways or the lakes with the combination of projects, environment and ecology.

Description

technical field [0001] The invention belongs to the field of pollution control of rivers and lakes, and further refers to an ecological dredging treatment method for rivers or lakes. Background technique [0002] Rivers are an important carrier of civilization continuation and economic development, an important part of the harmonious coexistence between man and nature, and one of the symbols of urban quality. In recent years, as my country's economy has taken off, the pace of urbanization has accelerated, and the amount of urban sewage has increased. Many urban rivers have been seriously polluted, and black and odor problems have become prominent. [0003] The main pollution sources of rivers and lakes are: ①domestic sewage; ②surface runoff; ③domestic garbage; ④construction pollution; The specific manifestations are: serious leakage of domestic sewage along the coast, and part of the sewage directly flows into the river; the fluidity of the river water body is poor, and the...

AI Technical Summary

Problems solved by technology

Although these methods play a positive role in the pollution control of rivers and lakes, when the dredging volume is large, a large amount of mechanical equipment and labor are required, the construction intensity and labor intensity are high, the management is inconvenient, and the implementation is difficult.

Moreover, the dredging method mentioned above only stays at the level of general engineering dredging in the traditional sense, without considering the combination of engineering, environment, and ecology to solve the problem of sustainable development of rivers and lakes or the restoration of "ecological niches"
