Process for improving wastewater quality of black and odorous rivers through in-situ bio-ecological comprehensive intervention

Abstract

The invention specifically relates to a process for improving wastewater quality of black and odorous rivers through in-situ bio-ecological comprehensive intervention, belonging to the field of eco-environmental protection technology. The process comprises the following steps: step 1, feeding a microbial product and a bio-complex enzyme; step 2, starting an aeration device and graphene mineralization equipment; and step 3, setting up an artificial floating island. According to the process for improving wastewater quality of black and odorous rivers through in-situ bio-ecological comprehensive intervention, the aeration device is installed in water to increase dissolved oxygen, and the graphene mineralization equipment is installed to activate atomic oxygen bottom mud, so an anaerobic environment of the bottom layer of a river is changed into an aerobic environment; the biological flora of the microbial product 5SSK-EP are activated to mineralize organic matters in the bottom mud into inorganic substances; then various aquatic plants are planted via the artificial floating island to absorb and transfer riverbed sediments and eutrophic substances in water, thereby achieving the effect of water quality purification; and thus, the water quality of black and odorous rivers can be efficiently improved, additional arrangement of microbial implantation is not needed, and production cost is lowered.

Description

technical field [0001] The invention relates to the technical field of ecology and environmental protection, in particular to a process for improving the water quality of black and odorous river channel in-situ bio-ecological comprehensive intervention sewage water quality. Background technique [0002] The water remediation industry has two methods for the treatment of water body silt, one is mechanical dredging, and the other is microbial pollution reduction. Mechanical dredging is still the mainstream of the industry. [0003] Among them, mechanical dredging is to use mechanical equipment to blow and stir the silt deposited on the bottom of the river into turbid water, which will flow away with the river water, thus playing the role of dredging. Although dredging can digest the total amount of sediment in a short period of time, there are still many problems, as follows: [0004] 1) Large amount of work: The current conventional physical dredging technology usually need...

Problems solved by technology

[0006] 3) Pollutants remain: Although the conventional physical dredging process can quickly consume the total amount of sediment, it cannot completely remove the sediment, and the residual sediment still has high concentrations of pollutants, which continue to be released into the water body;

[0007] 4) The cleared bottom mud is difficult to solve: the bottom mud cleaned by the physical dredging method is a mud-water mixture, which is mud with a water content above 90%, and the transportation volume is huge, and it cannot be landfilled or dumped directly. Therefore, once the mud Being cleared out of the water body will become a new problem

[0008] In addition, there are also problems in microbial pollution reduction: the introduction of microorganisms requires a still water body, otherwise the microorganisms will flow away with the water in the flowing water

Additional equipment will increase construction costs

[0009] In the prior art, graphene can adsorb organic matter and inorganic anions, and has discovered great potential in water treatment application research, but graphene has not yet been widely used in water treatment and water restoration industries, that is, graphene The application of materials in the water restoration industry is still in the experimental stage, and the effect on water body restoration has not been maximized
