Urban hard riverway modular multi-system coupled ecological restoration system

Abstract

The invention discloses an urban hard riverway modular multi-system coupled ecological restoration system, which mainly comprises: a microbial attachment substrate module purification system, a submerged plant module purification system and a large-scale macrobenthic module purification system. The submerged plant module purification system is located at the downstream of the microbial attachment substrate module purification system, and the large-scale macrobenthic module purification system is located at the downstream of the submerged plant module purification system. The system provided by the invention can effectively treat urban hard riverway black odor and water deterioration, enhance the self-purification ability of riverway, and make the riverway water reach the surface water standards. The system provided by the invention is conducive to constructing a complex aquatic organism habitat, enhancing riverway animal and plant habitat diversity, and increasing the riverway ecosystem stability.

Description

technical field [0001] The invention relates to the fields of environmental engineering, ecological engineering and water conservancy engineering design, in particular to a modular multi-system coupling ecological restoration system for urban hardened river courses. Background technique [0002] Rivers are rich in water, water conservancy and aquatic resources, and also have the functions of maintaining biodiversity, regulating climate, storing floods, regulating surface runoff, and ecologically restoring water quality. However, with the rapid development of industry and agriculture in our country, the acceleration of urbanization and the low-level and extensive economic development model, the discharge of industrial wastewater and domestic sewage is increasing, and a large amount of nutrients continue to flow into rivers, which has caused adverse effects on many rivers. Black and odorous rivers have become a common pollution problem in small and medium-sized rivers in my cou...

Problems solved by technology

[0004] A method for ecological purification of black and odorous river water (CN103332789A) discloses a water ecological purification technology for black and odorous rivers by setting up artificial wetlands and utilizing the comprehensive effects of soil-plant-microbes. Although it can purify the river water to a certain extent, But it is not suitable for urban rivers, and the hardening of river beds cannot construct an ecosystem of soil plant microorganisms

The river ecological construction and water restoration system (CN102276068A) uses an appropriate aeration system to re-oxygenate the river water, and then add beneficial bacteria. Although the bioremediation of the polluted river water has enhanced the water microbial community, it has not Setting up the microbial attachment base will easily lead to the loss of the beneficial bacteria flora put in, resulting in waste of resources
