Rapid method for constructing river way water ecosystem

Abstract

The present invention belongs to the technical field of water ecological restoration, and specifically discloses a rapid method for constructing a river way water ecosystem, the method includes the following steps: 1, collecting of to-be-repaired river way water ecological information; 2, detailed analysis of pollution information, sewage interception reoxygenation and blackness and odor removal by microbial decomposition; 3, planting of emergent proper aquatic plants, submerged plants and the like according to water and hydrological information; 4, control of algae by aquatic animals; and 5, water ecosystem maintenance; wherein aquatic plants are usually harvested in November each year, and plant body residues are cleaned up in early spring. Through combination of an ECO-EGG plug-flow aerator and the constructed river way water ecosystem, physical, chemical and biological-ecological approaches are effectively combined for phased treatment, water quality is rapidly improved, water eutrophication is controlled, water self-purification capacity can be improved, the water ecological structure and function can be restored, water quality can be long term and effectively improved, meanwhile the effectiveness, long effectiveness, economical efficiency and ecological compatibility of polluted water treatment can be unified.

Description

technical field [0001] The invention relates to the technical field of water body ecological restoration, in particular to a method for rapidly constructing a river water body ecosystem, which rapidly restores polluted river courses, ponds, etc. by using a combination of physics, chemistry and biology-ecology. Background technique [0002] Urban rivers are the infrastructure of urban construction, and most rivers undertake the functions of flood control, drainage and water supply. [0003] It is the carrier of material flow, energy flow and information flow in the urban ecosystem, directly or indirectly affecting urban production, life and ecological environment; Cutting bends and straightening and channelizing projects will result in a simplification of river sections and smooth and hardened riverbed surfaces. In addition, water conservancy projects will interfere with the continuity of river forms, causing serious damage to the structure and ecological functions of urban r...

Problems solved by technology

[0003] It is the carrier of material flow, energy flow and information flow in the urban ecosystem, directly or indirectly affecting urban production, life and ecological environment; Cutting bends and straightening and channelizing projects will result in a simplification of river sections and smooth and hardened riverbed surfaces. In addition, water conservancy projects will interfere with the continuity of river forms, causing serious damage to the structure and ecological functions of urban rivers, and a large number of organisms in the rivers will disappear; At the same time, with the acceleration of urbanization, a large amount of industrial wastewater and domestic sewage are discharged, many urban rivers have problems such as black odor, eutrophication, sharp decline in biodiversity, and monotonous ecosystems. Water facilities, people are gradually moving away from the river

[0004] People pay more and more attention to the treatment of polluted rivers. The following methods are mainly used for traditional river improvement: 1) Engineering measures, such as artificial aeration, sediment dredging, overflow dam construction, water change, water diversion, etc.; 2. ) Chemical methods, such as flocculation and sedimentation, chemical algae removal, etc.; 3) Biological methods, such as adding microbial agents, planting aquatic plants, etc., but these methods have their own defects: 1) Engineering measures and chemical methods are mostly fast It is effective, but it cannot fundamentally eliminate water pollutants and restore the self-purification ability of the water body, and the water body will return to the polluted state after a period of time; 2) The dredging of the sediment will have a negative impact on the benthic habitat and have an adverse impact on the flow of flood discharge. , a large amount of dredged sediment needs to be disposed of properly, otherwise it will easily cause secondary pollution; 3) chemical methods can easily cause secondary pollution; 4) most complex bacteria have poor removal effect on total phosphorus in water; 5) single biological method The built system has a simple structure, poor ability to resist external interference, and the effect is very limited under the action of external interference

So far, there is no single biological, physical or chemical method that can effectively remove pollutants in polluted water bodies, improve the self-purification ability of water bodies, and restore the ecological functions of water bodies.
