A small watershed water ecological restoration integrated management system and method

Abstract

The invention discloses a small watershed water ecological restoration integrated treatment system and a small watershed water ecological restoration integrated treatment method. The small watershed water ecological restoration integrated treatment system comprises a dredging repair subsystem, a catalytic degradation subsystem and an ecological floating island subsystem, wherein the systems are sequentially arranged in a to-be-treated watershed along a river course flowing direction, the catalytic degradation subsystem is arranged at the central position of a to-be-treated river course, and isused for catalytically degrading macromolecular organic substances and non-active metals in the water body of the watershed, the dredging repair subsystem is arranged in the upstream area of the river course of the to-be-treated watershed, and is used for differentially settling the riverbed silt at the bottom portion of the river course, and the ecological floating island subsystem is arranged in the downstream area of the river course of the to-be-treated watershed, and is used for planting aquatic organisms so as to balance and reduce the nutrients in the water body. According to the present invention, with the system and the method, the river course dredging and the catalytic degradation of macromolecular organic substances and non-active metals are achieved, the nutrients in the water body are absorbed so as to avoid the circulating pollution caused by the eutrophication of the water body.

Description

technical field [0001] The invention relates to the field of environmental engineering, in particular to an integrated management system and method for water ecological restoration in small watersheds. Background technique [0002] The origin and development of human beings and life are inseparable from the nourishment and supply of water. Only with water can there be life. However, the current water environment situation is not optimistic, especially due to the characteristics of strong fluidity, large treatment area, and inability to collect and treat in a centralized manner in rivers and river basins. As a result, there is currently no economical, affordable, and long-term effective way to restore the ecological and regulatory functions of the water system. An economical, long-term and effective water treatment plan will be a long-term topic for many years to come. At present, catalytic decomposition technology is the most popular research topic, such as a low-power elect...

Problems solved by technology

From the mechanism of the catalytic reaction, we can see that the pure catalytic degradation technology will consume the dissolved oxygen in the water body, reduce the dissolved oxygen in the water body, decompose the organic matter into the inorganic state, and remove a small part of the deep mineralization into CO2, H2O, N2 , P, etc., most of the mineralized N and P in the water body still exist in the form of no ground state, resulting in eutrophication of the water body and the formation of cyclic pollution.
