Description

High-efficient filterable breathing dam

Technical Field

The utility model relates to the technical field of dams, in particular to a breathing dam with efficient filtration.

Background

For some small watershed river channels with larger span and smaller flow, the small watershed river channels serve as a certain agricultural irrigation water effect when flowing through a crop planting area, and also have a certain landscape effect and play a certain pollution discharge effect when flowing through a city or other people's mouth land. If such river is polluted and blocked, a series of effects are caused, and if water body sludge is accumulated, water flow is blocked, eutrophication is serious and the like, black and stink and other phenomena are generated, so that not only is the agricultural irrigation unfavorable, but also a certain negative effect is generated on residents living around.

Therefore, the river channels need to be filtered, aerated and the like in time to remove a large amount of impurities in the river channels, promote the growth of microorganisms, eliminate the eutrophication of water bodies and avoid the generation of black and odorous substances, sludge and the like. For example, CN102677629B is a filtering dam system, CN108824373a is an environmental protection dam for treating river pollution and purifying water quality, and these common water treatment dams are seemingly good in water treatment effect, and in fact, they are mainly concentrated in cleaning water surface or floating impurities in water, and have no good cleaning effect on sludge accumulated at the bottom of water, and long-term operation can also cause sludge accumulation, water blockage, etc.

In conclusion, the dam with a good water body cleaning and filtering effect is designed, and normal operation of the river in the small river basin can be guaranteed to a certain extent.
