Problems solved by technology

[0004] 1) Emergent plants are only planted on the surface, or a combination of fillers is suspended under it, but the filler film is affected by water flow, microbial species, etc., and has a single effect on water pollutants, which has limitations
[0005] 2) The utilization rate of water body space is small
Ordinary ecological floating beds or floating islands only use the water surface and shallow surface of rivers, lakes, and reservoirs, and the scope of action space is small, and the governance effect is limited
[0006] 3) The large coverage area will block the sunlight injected into the water body, seriously affect the photosynthesis and respiration of submerged plants, phytoplankton, microorganisms, etc. in the water body, inhibit the normal growth and reproduction of submerged plants, and thus affect the growth of plants. Governance effect and bring secondary pollution
[0007] 4) Limited by dissolved oxygen in water
Polluted rivers, lakes, and reservoirs have low dissolved oxygen and high suspended matter content. Too low dissolved oxygen will affect the growth of plants, thereby affecting the treatment effect
[0008] 5) As the water depth increases, the absorption of pollutants in the middle and lower layers of rivers, lakes, and reservoirs with relatively deep water levels by ordinary ecological floating beds gradually decreases, and has no direct effect on the degradation of pollutants in the bottom sediment of the water body
[0009] The application of submerged plants is also involved in the existing ecological restoration system, but this application also has limitations:
[0010] 1) The planting of general submerged plants needs to be artificially cultivated after drainage and dredging of rivers, lakes, and reservoirs, and the cost is relatively high;
[0011] 2) Cultivation methods include throwing seeds, throwing seedlings, cuttings, etc. After the amount or incremental pollution of rivers, lakes, and reservoirs exceeds the scope of their pollution-holding and pollution-resistant capabilities, the survival rate is low and the maintenance cost is high. , lakes, reservoirs or seasonal rivers and lakes are not suitable for this planting method;
[0012] 3) It is not suitable for growth on hardened river beds;
[0013] 4) It is easily damaged by benthic aquatic animals and water flow, and the maintenance cost is high;
[0014] 5) In polluted rivers, lakes, and reservoirs, high content of suspended solids will not only significantly reduce the transparency of water bodies, but secondly, suspended solids will adhere to the surface of submerged plants, which will seriously affect the photosynthesis and respiration of submerged plants due to the limitation of light. , inhibit the normal growth and reproduction of submerged plants, thus affecting the treatment effect of submerged plants and causing secondary pollution

Embodiment 1

[0077] Embodiment 1 black and smelly river, lake, reservoir control

[0078] A submersible-floating ecological restoration water cube system was put into black and smelly rivers, lakes and reservoirs in a certain place in Jiangsu. The structure of the system is as attached Figure 1-5 Shown:

[0079] An ecological water cube system, including a floating tank 1 and an aeration guide rod 6 running through the center of the floating tank, "ecological scuba", emergent plants 2, submerged plants 10, biological filler 11, artificial light source 9, and aeration device , jet pump 13;

[0080] 1) The buoyant tank 1 is a hollow cavity made of high molecular polyethylene material, and the center of the upper surface and the lower surface of the buoyant tank 1 are provided with through holes, and the aeration guide rod 6 runs through the buoyant tank 1 longitudinally through the through holes, and the buoyant tank 1 Float up and down in the water body along the aeration guide rod 6;

Abstract

The invention discloses a submerging type ecological water cube system used for black and stink water body pollution treatment, ecological restoration, water quality improvement, and water body maintenance in rivers, lakes, reservoirs, river mouths, and gulfs. The submerging type ecological water cube system comprises tank bodies, aeration guide rods, ecological water lungs, emergent aquatic plants, submerged plants, a microbial carrier inoculated with microbes, and external artificial light sources; the emergent aquatic plants and the submerged plants grow on system upper surface and peripheral side surfaces respectively, so that full utilization of the three-dimensional space from water bottom to water surface is realized, the contact effect area of plants with water body is enlarged, full absorption on nitrogen phosphor, reduction of suspension matters, and supplement of ecological oxygen demands are realized; the microbial carrier is inoculated with a microbial agent to increasedmicrobe contact effect specific surface area; the ecological water lungs composed of aquatic animals are used for filtering and eating of eutrophic substances such as planktonic algae, suspension particles, and organic chips, water plant photosynthesis and adsorption effect on nitrogen and phosphor are promoted, water body black color and stink smell are eliminated, and a water body ecological system is established.

Description

technical field [0001] The invention relates to the technical field of ecological environment engineering, in particular to a submersible-floating 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 development of social economy and the increase of population, the problem of water environment pollution in our country is becoming more and more serious. The landscape water body of urban rivers and lakes is a complex ecosystem. Factors affecting the sensory perception of landscape water include suspended solids, dissolved oxygen, nutrient-rich substances, etc., which cannot be completely solved by traditional single technical treatment, but comprehensive technical means , that is, by building a complete water ecosystem and making full use of the advantages of ecosystem restoration capabilities, the problem can be funda...
