River channel water body ecological restoration system

Abstract

The invention relates to the technical field of ecological restoration, and discloses a river channel water body ecological restoration system which comprises a river channel and a river channel water body. An aeration device is arranged at the bottom of the river channel. At least one ecological floating island is arranged on the river channel water body, and aquatic plants are planted on the ecological floating island. Carbon fiber grass serving as a microbial strain carrier is arranged at the bottoms of the ecological floating islands, and a special culture medium for growth and reproduction of microbial strains is put into the river channel water body. According to the river channel water body ecological restoration system, aquatic plants are planted on the ecological floating islands, carbon fiber grass is arranged at the bottoms of the ecological floating islands to serve as a carrier of microbial strains, a special culture medium is put into the water body, and meanwhile, the aeration device is arranged at the bottom of the river channel, so that inherent earth microorganisms in bottom soil can be activated. Therefore, the synergistic effect of the plants on the water surface, the microorganisms in the water and the earthy microorganisms in the bottom mud is realized, a three-dimensional treatment effect is formed, and the treatment efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of ecological restoration, in particular to a river water ecological restoration system. Background technique [0002] With the rapid development of the economy, the acceleration of urbanization and the rise of industry, factories, agriculture, and domestic sewage on both sides of the river are directly discharged into the river without treatment, which leads to the deterioration of the water quality of the river, and even seasonal and perennial black and odorous water bodies. . Therefore, improving the water quality of rivers and restoring the ecosystem and social functions of rivers is one of the key tasks to be solved in the process of urban sustainable development. [0003] The current conventional river surge treatment methods mainly include: sewage pipe network interception, mechanical dredging, adding flocculants, and simply injecting microbial agents.

Problems solved by technology

[0003] The current conventional river surge treatment methods mainly include: sewage pipe network interception, mechanical dredging, adding flocculants, and simply injecting microbial agents. However, these methods have shortcomings: due to the intricate connection network of underground pipes, Sewage is discharged into the river due to the wrong connection or missing connection of the pipe network; the mechanical dredging project has a large amount of work and high cost, and the disposal of sludge is very difficult, and improper disposal will cause secondary pollution

The micro-toxicity of chemical flocculants will affect the river ecosystem; most of the current microbial agents are directly put in, dispersed in the water body, without carrier attachment, easy to lose with water, and it is difficult to achieve the best restoration effect
