Six proposals for improving water quality in rivers
Hunan Kinglv Environmental Engineering Co., Ltd. tells you six proposals for improving water quality in rivers:
(1) Wetland engineering water purification technology
The natural wetland treatment system is constructed through natural artificial lakes through reasonable artificial dressing. Under the combined action of water-resistant plants and soil, the water quality of rivers and lakes is purified to a certain extent.
(2) Contact oxidation technology of natural and artificial fillers
When the water flows through the natural filter material, the filter adsorption occurs, and the surface growth biofilm oxidatively decomposes the organic matter; or the artificial material such as plastic (rope, fiber) is used as the contact oxidation filler to purify the polluted water body of the river.
(3) Jet aeration and aeration technology
The floating-type diffusion aeration device is used to increase the dissolved oxygen value in the water to provide conditions for the oxidation of organic matter in the water body. It can create a huge circulating water flow in the water, and at the same time aerate the gas, and stir the huge lake water with a small amount of energy. On this basis, some fillers are properly laid on the flow path of the water flow, and it succeeds in polluting the lake. The contact oxidation rule of law is realized, which can reduce the BOD content in the lake water quickly, efficiently, and with low energy consumption, prevent the accumulation of organic sludge, and eliminate the odor of the lake water. At the same time, the aeration aerator and the filler are all sunk in the water without affecting the water surface.
(4) Biological floating bed water quality improvement technology
In heavily polluted waters, since the aquatic ecosystem has been completely destroyed, the self-purification capacity of the water body is lost, and the mechanism of natural recovery no longer exists. Artificially construct artificial ecosystems, use environmental biotechnology to absorb and reduce N, P and harmful substances in water, purify water quality, and rebuild and restore aquatic ecosystems in limited areas.
(5) Into the river sewage dispersion treatment technology
In order to reduce the investment in water pipelines and the scale of sewage treatment plants, especially in the suburbs, the sewage treatment system is designed to make the point source sewage be treated in situ before entering the river.
(6) Bypass new water and water technology - integrated membrane bioreactor
The integrated membrane bioreactor can reduce COD and NH3-H, and its effluent quality can reach the first-class A standard of urban sewage treatment discharge standard, and its effluent is stable, with small footprint and movable. It can be easily managed in river treatment. And can guarantee the water quality.
