Description
Technical field
The present invention relates to Accrete clearing device field, particularly relate to a kind of bank self-circulation type aeration Accrete clearing device for Landscape River lake and control method.
Background technology
In recent years, construction or maintenance urban landscape rivers have been the target that each metropolis is competitively chased.Especially after " 18 is large ", build the ambitious goal that " beautiful China " becomes Ecological Civilization Construction, and water becomes important element indispensable in urban planning with its distinctive intelligence.The construction and development in city is puted forth effort to advance Green Development, cycle development, low carbon development.Certainly, only have the water yield to enrich, sense organ be graceful, function that healthy harmless water body (Landscape River, artificial lake etc.) could realize its view and Ecological regulation well.
But, compared with the water body such as natural lake, river, artificial landscape lake, secondary river course, city etc. have mobility relatively slowly, the water yield is less, update time is longer, with the feature that connectedness is poor, environment capacity is less of periphery water system, and weak to pollution load resistivity, water quality easily worsens.The survey showed that in a large number, and some landscape lake water quality of China is general worsening, and water transparency is low, and explosive China of flooding, distributed stench, not only lost landscape function, even welding, be detrimental to health summer.According to the hydraulics feature of artificial landscape lake, adding Great Lakes's partial water liquid flowability, improve water reoxygenation rate, is the measure effectively keeping water quality good.
Improve in the method for water quality multiple, drop water aeration is one of effective measures improving Dissolved Oxygen in Water; And the many employings of lake, river desilting dam after the mode of artificial mechanism carry out, management and running difficulty is large, cost is high.Traditional Accrete clearing device mostly is land use, recently also has Accrete clearing device that is amphibious, diving function.But its operating principle be all utilize submersible sewage pump realize cleaning and dispatch mud, operability and operating efficiency lower.
Summary of the invention
The invention provides a kind of bank self-circulation type aeration Accrete clearing device for Landscape River lake and control method, the present invention is by building self-circulation type aeration Accrete clearing device on loke shore limit, river, improve water reoxygenation rate, remove bottom sludge, thus improve the water quality condition in waters, local, Landscape River lake, described below:
For the bank self-circulation type aeration Accrete clearing device in Landscape River lake, described aeration Accrete clearing device by pump house, aerating system and desilting system three part form,
Described pump house is built on loke shore limit, river, is close to described pump house and is building drop water aeration pond near He Hu side, and drop reoxygenation groove is equipped with in the upside in described drop water aeration pond;
