River channel water body in-situ remediation system, ecological restoration system and application

Abstract

The invention provides a river channel water body in-situ remediation system, an ecological restoration system and an application, and relates to the technical field of ecological pollution treatment.According to the river channel water body in-situ remediation system, a primary water blocking dam and a secondary water blocking dam are arranged in an original river channel, and a water level is lifted by the primary water blocking dam and the secondary dam so that the remaining time of river water in a facultative ecological pond and an aerobic ecological pond can be improved, and accordinglysuspended matters can be trapped, and mud and sand can be settled; solar reoxygenation equipment, floating wetlands, aquatic plants, aquatic animals and carrier fillers in the facultative ecologicalpond and the aerobic ecological pond form a water body self-cleaning system, so that organic matters such as COD, nitrogen, phosphorus and other pollutants in the water are efficiently removed, the water quality of a water body is purified, a river ecological system is improved, and the self-cleaning ability of the water body is helped to be recovered; and in addition, according to the river channel water body in-situ remediation system, the existing river channel can be fully utilized so that construction land can be greatly saved, and less investment, short construction period, simple process and easy maintenance can be realized.

Description

technical field [0001] The invention relates to the technical field of ecological pollution control, in particular to an in-situ restoration system for river water bodies, an ecological restoration system and applications. Background technique [0002] In recent years, due to the discharge of various domestic sewage, industrial production sewage and even the tail water of upstream sewage treatment plants along the river and lake, a large amount of organic matter, nitrogen, phosphorus and other pollutants have poured into the water environment, resulting in more serious water pollution, causing national attention. Water treatment and restoration of the ecological environment of the Black and Stinky River has become a key strategy for a new round of reform and development. The improvement of environmental pressure and the improvement of the quality of the living environment have become a top priority. [0003] The natural river itself has good self-purification ability.

AI Technical Summary

Problems solved by technology

Since the pollutants received by the river are far greater than their own pollution-holding capacity, the water quality of many rivers and lakes is seriously polluted, the self-purification function of the water body is affected, and the ecological environment is seriously damaged.

At present, the treatment technologies for urban rivers and lakes mainly use projects such as sewage interception, dredging, bank revetment, water diversion and water diversion, and greening, which can solve the problem of river pollution in the short term, but often treat the symptoms rather than the root cause. As a result, the aquatic ecosystem of the river will be destroyed instead, and the aquatic ecological function will not be restored.

[0004] At present, the treatment of polluted rivers is mostly ectopic restoration of the river, that is, the river water is led to the water treatment structures on the bank for treatment and then discharged into the river, which not only requires a large amount of land, construction of treatment structures, installation of sewage lifting and treatment equipment etc., and the investment is large, the operating cost is high, and the maintenance is inconvenient
