Black-odor urban river three-dimensional in-situ ecological restoration system and in-situ ecological restoration method

Abstract

The invention relates to a black-odor urban river three-dimensional in-situ ecological restoration system and an in-situ ecological restoration method. A water quality online monitoring unit is arranged in the black-odor urban river position; the output of the water quality online monitoring unit is connected with a data control center through a wireless transmission unit. The black-odor urban river three-dimensional in-situ ecological restoration system is characterized by also comprising an ECO Lab ecological model, a pollution control environment-friendly boat, an ecological reaction pool, a plant-natural biological membrane composite ecological floating bed and a micro-nano pushing flow aeration machine; the output of the ECO Lab ecological model is connected with the data control center. The quantity of rotifera, cladocerans and copepod organisms in the water body can be promoted to be obviously increased; the general quantity of the zooplankton can be increased by 1.5 to 3 times. The ecological restoration agent can be completely consumed by microbes; no secondary pollution exists. The system and the method have the advantages that the ammonia concentration is obviously reduced; the transparency is greatly improved; the dissolved oxygen content is improved by one order of magnitudes; the total phosphorus concentration is only 1 / 8 to 1 / 5 of that before the project; the chemical oxygen demand is only 1 / 8 to 1 / 5 of that before the project.

Description

technical field [0001] The invention belongs to the field of water environment restoration, and relates to a method for restoring black and odorous water bodies, in particular to a three-dimensional in-situ ecological restoration system for black and odorous rivers, and a three-dimensional in-situ ecological restoration method using the system. Background technique [0002] With the rapid development of the economy, the continuous acceleration of the urbanization process, and the rapid increase of the urban population, the urban rivers have been seriously polluted, and the phenomenon of black and odorous water bodies has appeared in large areas, seriously affecting the image of the city and the lives of citizens. [0003] Black and odorous water is an extreme phenomenon of organic pollution and a description of the extreme pollution state of water, mainly caused by the metabolism of algae and bacteria in water and the discharge of a large number of pollutants. The blackening...

Problems solved by technology

[0011] Although the above-mentioned prior art discloses some treatment methods for black and odorous rivers, which can meet certain needs and achieve better treatment effects, there are still certain defects in these treatment methods: such as the use of microbial agents or biofilm systems. High system or processing cost limits widespread use

Due to the complexity of black and odorous water bodies, only a single method and technology is used for treatment, the treatment effect is poor, or the duration of the effect is very short, and the effect of curing the root cause cannot be achieved at all. Negative impacts such as the healthy development of the ecosystem

Moreover, most of the existing technologies for treating black and odorous water bodies are based on ex-situ restoration, and in-situ ecological restoration of black and odorous water bodies is rare.
