Description
Technical field
This utility model relates to environmental protection class water purification technology field, is specifically related to the reoxygenation device of a kind of unpowered river surface water.
Background technology
Fast development along with China's economy, environmental pollution situation is increasingly serious, the natural water such as urban river, lake is contaminated to some extent, the most middle-size and small-size water body is chronically at eutrophic state, black smelly phenomenon even occurs, have a strong impact on resident living and urban environment, constrain Construction of Ecotypic City.Urban polluted water all shows common phenomenon, i.e. dissolved oxygen content is too low, even level off to zero, its basic reason is that water pollutant causes heterotrophic microorganism raised growth to breed, cause the oxygen consumption rate of water body more than reoxygenation speed, run out of the dissolved oxygen in water body, aerobic microbiological is made gradually to lose growth vigor, anaerobe occupies leading, water body presents anaerobic state, organic pollution is decomposed, by anaerobe, materials such as generating methane, ammonia, hydrogen sulfide, and water body emits bad smell, water degradation.
The most direct measure improving Dissolved Oxygen in Water content is to use the method being manually filled with air to water body, make up the deficiency of natural reaeration, accelerate water reoxygenation process, to improve the dissolved oxygen levels of water body, recover and strengthen the vigor of aerobic microbiological in water body, make the pollutant in water body be purified, improve the environmental quality of water body, recover water ecosystem as early as possible.
