A Multidimensional Ecosystem Restoration Method

Abstract

The invention provides a multi-dimensional ecological system remediation method. The remediation method comprises the steps of: treating multi-dimensional ecological water quality, controlling internal contamination and controlling external contamination, wherein the step of treating the multi-dimensional ecological water quality is mainly for constructing a multi-dimensional ecological system in a water body; the step of controlling the internal contamination is mainly for eliminating contamination caused by release of nutritive salts from bottom mud of a lake body and performing dredging and bottom mud remediation improvement on an artificial lake, an original lake body or river which is seriously contaminated; and by the step of controlling the external contamination, an external water body entering the lake body mainly includes rainwater and a part of life non-drinking water so that the water quality of water bodies entering the lake can not generate a destructive influence on a lake body ecological system and a water quality effect. The remediation method has the beneficial effects that from the angle of internal contamination and external contamination influencing water body quality, a general survey of the whole process from a water source to completion of a waterscape function of the water body is combined with all advantageous measures for maintaining the water body quality, so that the water body quality effect is all-around ensured and the multi-dimensional remediation is realized.

Description

technical field

[0001] The invention belongs to the field of aquatic ecosystem restoration, and in particular relates to a multidimensional ecosystem restoration method for ecological self-purification of natural lakes or artificial lakes. Background technique

[0002] The pollution of lakes in my country is mainly due to point source pollution of industrial wastewater and domestic sewage, overfishing, etc. The most important thing for ecological restoration of degraded river ecosystems caused by these driving forces is to reduce or eliminate the pollution caused by river ecosystems. Drivers of degradation, allowing rivers to recuperate. In addition, the following two methods can also be adopted: one is to reduce the degree of artificial linearization of the river and increase the degree of curvature of the river to increase the diversity of river habitats, thereby increasing the diversity of aquatic biodiversity; the other is to plant biological barriers ( The type and widt...

Examples

Embodiment 2

[0058] A city lake in the south is selected as the experimental landscape lake, with an area of ​​about 20,000 cubic meters and an average depth of 1.0m.

[0059] The lake was originally planned to be the central landscape lake of the plot area, but under the high-speed construction environment of the city, the improper use of the lake, the leakage of the municipal sewage pipe network and the rainwater pipe network, and the collection of water caused the current lake water to be turbid and low in visibility. , the water body in most areas is black, the organic pollution is serious, and there is a very serious eutrophication problem.

[0060] The conventional water source of the lake is mainly rainwater from the surrounding residential areas and public green belts, and there is another mountain (smaller) rainwater catchment branch channel into the lake; in dry climate years, the lake replenishment water is drawn from a large water system running through the city, and the water q...
