Fluviolacustrine water body purification treatment apparatus capable of floating on water surface

Abstract

The invention relates to an apparatus for treating fluviolacustrine water pollution. The apparatus for treating the fluviolacustrine water pollution comprises an oxygen making machine, an ozone generator, a flow ejector, a catalytic reactor, a plate heat exchanger, a circulating pump, a pure water box and a titled-plate catalytic reaction kettle. These apparatuses are connected through pipelines according to a process flow, are mounted in a modularized box body in an integrated manner, and are put on a platform which floats on a water surface, so as to form a floatable and movable fluviolacustrine water body purification treatment apparatus. The apparatus can float and be moved on the water surface, does not need civil engineering, is convenient to mount and simple to operate, and can be used for realizing quick mounting and quick putting into use. By using the apparatus for treating the fluviolacustrine water pollution, macromolecular organic compounds such as a surface active agent can be efficiently degraded; the total phosphorus content and ammonia nitrogen in a water body can be reduced; further, alga and fungus substances can be quickly killed. The design of the same style of the scenic belt of a surrounding river course landscape can be adopted for the appearance of the floating platform of the apparatus for treating the fluviolacustrine water pollution, which is provided by the invention, so as to form a scene harmonious with the scenic belt.

Description

technical field [0001] The invention relates to a device for treating pollution of river and lake water, in particular to a device for purifying and treating river and lake water that can float on the water surface. Background technique [0002] The problem of water pollution has deteriorated rapidly with the rapid advancement of industrialization. The Haihe River, Huaihe River, and Liaohe River in the north have turned black and smelly, and have almost become super sewage ditches. Nutritious, often loses use value due to algal blooms. Moreover, water pollution is still deteriorating, spreading and developing from tributaries to main streams, from cities to rural areas, from surface to underground, and from land to sea. [0003] Usually, the treatment methods adopted for surface water such as rivers and lakes include physical restoration technology, chemical restoration technology and biological restoration technology. Physical methods include dredging sediment, mechanical...

AI Technical Summary

Problems solved by technology

Physical methods include dredging sediment, mechanical algae removal, aeration, water diversion to wash away silt, etc. This method is simple to operate and low in cost, but it often treats the symptoms but not the root cause; chemical restoration is to add chemicals and adsorbents to change the oxidation-reduction potential, pH, adsorption of suspended matter and organic matter in the sedimentation water, using the chemical reaction of pollutants to separate and recycle harmful substances in sewage, or transform them into harmless substances. Although chemical methods are effective, they require a large amount of chemical agents , the cost is expensive, and it is easy to cause secondary pollution. Moreover, it generally needs to be introduced into a sewage treatment plant for treatment, which requires a large amount of engineering and troublesome operation; bioremediation uses plants, animals, and microorganisms to absorb, degrade, and transform water bodies Pollutants in the environment, this method has a high degree of enrichment of metal ions and refractory toxic organic substances, and the end of the biological chain will enrich metal ions and toxic organic substances, and the living conditions required for biological growth are harsh, and some water bodies are too polluted. It is difficult for organisms to grow, and some biological functional bacteria are added, but the reproductive rate of functional bacteria is slow, requiring more than 24 hours on average, and the sewage after treatment is difficult to meet the standard, and it is easy to introduce foreign bacterial contamination.
