River course black and odorous water body treatment device and method based on mbbr process

Technical Field

The embodiment of the invention relates to the technical field of environmental protection, and particularly relates to a riverway black and odorous water body treatment device and method based on an mbbr process.

Background

The shallow water river channel, lake and other water areas are large and shallow, the water bottom is frequently disturbed by wind and wave, and is easily influenced by human activities, and eutrophication and aquatic vegetation degradation become the problems of wide existence of shallow water areas in the global range. As one of the important primary producers in the water ecosystem, the structure and spatial distribution of aquatic vegetation communities have a significant impact on the water ecosystem.

Aquatic plants generally grow in areas with slow water flow and in areas with wet edges of the water system. Aquatic plants are generally classified into emerging plants, floating plants, submerged and floating plants, and hygrophytes according to their lifestyle. In natural waters, these several plants grow together, constituting the aquatic plant system of the water.

The aquatic plants improve the diversity of species such as fishes, benthonic animals, protozoa and the like by increasing the space ecological niche of the ecological system, and maintain the abundance of the species of the aquatic ecological system. During the growth process of the aquatic plants, the nitrogen and phosphorus nutritive salts in the water body can be directly absorbed to improve the water quality, and the root parts can also have the capacity of absorbing and accumulating heavy metals (Zn, Cr, Pb, Cd, Co, Ni and Cu). The resistance of the aquatic plant leaves to water flow and the fixing force of the root system to underwater sediments can effectively reduce the hydrodynamic disturbance intensity of the water column body and the water-soil interface, thereby reducing the release of endogenous pollution caused by sediment resuspension. To a certain extent, the structure and distribution of the aquatic plants determine the state of the ecosystem of the water area, and the health level of the ecosystem of the clear water type water area taking the non-phytoplankton as a main primary producer is superior to that of the muddy water type water area taking the phytoplankton as a primary producer. Therefore, the aquatic vegetation recovery and regulation become important means for improving the water environment and improving the health of the water area ecosystem.

Generally, the growth width of the aquatic plants can reach 1050cm when the water flow speed is less than 10cm/s, and is only 210cm when the water flow speed is more than 10cm/s, and emerging plants are taken as the main part. When the water temperature is lower than 30 ℃ and the water depth is less than 1.5m, the substrate condition is completely suitable for the growth of the submerged plants, but the application of the submerged plants is limited due to the fact that the water flow speed is too high, the water level is too deep or planting soil is lacked at the bottom of a water system.
