Ecological remediation method and remediation system for natural water body

Abstract

The invention discloses an ecological remediation method for a natural water body. The method is characterized by comprising the following steps: constructing a plurality of filter bed type constructed wetlands on the bank of a natural water body to be ecologically remediated, guiding water in the natural water body into the filter bed type constructed wetlands for treatment, and re-discharging the treated water into the natural water body, so as to fulfill the aim of ecologically remediating the natural water body by such cyclic treatment; automatically regulating speed at which the water in the natural water body enters the constructed wetlands according to light intensity in a treatment process, and further regulating treatment speed of the constructed wetlands according to the light intensity. The invention also discloses an ecological remediation system for the natural water body. According to the ecological remediation method and the remediation system for the natural water body, the filter bed type constructed wetlands, the natural water body, submerged plants, fish, a circulating pump and a solar power generation device form a micro-ecological system, and the micro-ecological system can be automatically regulated according to a climate condition without an externally input energy resource; the natural water body can be stably kept at a low-alga and low-turbidity level for a long time.

Description

technical field [0001] The invention relates to the field of ecological restoration of water bodies, in particular to a method and system for ecological restoration of natural water bodies. Background technique [0002] At present, the traditional water ecological restoration technologies on the market mainly include adding biological enzymes, planting submerged plants, circulating air flotation, circulating filtration and other technologies, which have a certain effect on improving the quality of water environment, eliminating black and smelly rivers, and improving the transparency of surface water. However, its defect is that it does not solve the problem from the perspective of ecological balance, and does not start from improving the self-purification ability of water bodies. Many water body restoration projects cannot stand the test of time, and they will return to pollution and blackness in a short period of time. Contents of the invention [0003] In view of the abo...
