Submerging type ecological restoration water cube used for black and stink water body treatment and water quality improvement

Abstract

The invention discloses a submerging type ecological water cube system used for black and stink water body pollution treatment, ecological restoration, and water quality improvement in rivers, lakes,reservoirs, river mouths, and gulfs. The submerging type ecological water cube system comprises submerged plants, a net-shaped framework, submerged plant plantation interfaces, a biological filling material inoculated with microbes, and light sources; the submerged plants grow on system upper surface and peripheral side surfaces respectively, so that full utilization of the three-dimensional spaceof the water body is realized, and the contact effect area of plants with water body is enlarged; the external light sources are used for supplement of deficiency of natural illumination; the biological filling material is inoculated with a microbial agent to realize adsorption, conversion, and degradation of pollutants with microbes, promote water plant photosynthesis and adsorption effect on nitrogen and phosphor eutrophication salts, eliminate water body black color and stink smell, establish a water body ecological system, and recovery and improve water body self cleaning capacity.

Description

technical field [0001] The invention relates to the technical field of ecological environment engineering, in particular to a submersible ecological water cube system used for black and odor pollution control, ecological restoration and water quality improvement of rivers, lakes, reservoirs, estuaries and bays. Background technique [0002] With the rapid development of industry and the acceleration of urbanization, the pollution of lakes, rivers and other water bodies is increasing day by day. A large number of rivers in cities have become black, smelly or eutrophic. The shortage of water resources has gradually become an important problem to be solved in modern society. . [0003] Submerged plants absorb nutrients (such as nitrogen, phosphorus, etc.) in the water body during their growth, so they play an important role in the aquatic ecosystem. For eutrophic rivers, lakes, and reservoirs, the method of harvesting submerged plants in a planned way can be used to transfer e...

Problems solved by technology

[0004] However, the current submerged plant purification technology has the following problems: 1) General planting needs to be artificially cultivated after river drainage and dredging, which is costly; 2) Cultivation methods include throwing seeds, throwing seedlings, cuttings, etc. After the incremental pollution exceeds the scope of its pollution-holding and pollution-resistant capacity, its maintenance and cost requirements are high, and it is not suitable for this planting method in flood channels or seasonal rivers and lakes; 3) Submerged plants are not suitable for hardened riverbeds. ; 4) Plant roots are easily damaged by benthic aquatic animals and water flow; 5) In heavily polluted water bodies in cities, high levels of suspended solids will not only significantly reduce the transparency of water bodies, but also allow suspended solids to adhere to the surface of submerged plants, limited by light , will seriously affect the photosynthesis and respiration of submerged plants, inhibit the normal growth and reproduction of submerged plants, thus affect the treatment effect of submerged plants and bring secondary pollution
