Rough filtration type floating pontoon water taking device

Abstract

The invention discloses a rough filtration type floating pontoon water taking device. The device comprises a floating pontoon arranged in a reservoir, a water inlet is formed in the side face of a cabin of the floating pontoon, a filtering device is arranged in the position, in the water inlet, of the cabin, and water purified by the filtering device enters a closed water collecting bin arranged on one side of the filtering device; the water inlet is formed in the side face of the cabin, when the filtering device is not opened, water in the reservoir enters the water collecting bin through the water inlet and a water door arranged on the water collecting bin, and the water entering the water collecting bin is drained out through a water outlet pipe arranged in the water collecting bin; a first hydraulic power propeller is arranged at the bottom of the floating pontoon, and the direction of water flow propelled by the first hydraulic power propeller intersects with the direction of water flow entering the filtering device; a back flush water pipe is arranged in the water collecting bin and connected with the filtering device. Siphon-type water outflow is applied in the rough filtration type floating pontoon water taking device, water is pressed into the back flush water pipe through liquid level difference in the back flush process, then back flush is performed, energy consumption is reduced, and the rough filtration type floating pontoon water taking device has the advantages of being easy to run, capable of saving land, convenient to disassemble and maintain and the like.

Description

technical field [0001] The invention relates to a purification water intake structure in the field of water supply technology, in particular to a water intake pontoon installed in surface water sources such as lakes and rivers to reduce particulate matter in raw water, which can realize water collection, coarse filtration, and backwashing when the water quality of the water source deteriorates Integral coarse filter pontoon water intake device. Background technique [0002] The water environment suffers from different degrees of pollution and the continuous improvement of drinking water quality standards. In some specific periods, traditional water treatment facilities, such as eutrophic algae outbreaks in water bodies and flash floods in rainy seasons, cause a large amount of organic matter and sediment to enter the water body. The water quality may not meet the new water quality standards, so how to improve the water quality of water treatment plants and reduce infrastruct...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the problem that a large amount of algae and a large amount of sediment in the raw water directly enter the water treatment plant without treatment, which leads to the difficulty of treatment in the water treatment plant, the purpose of the present invention is to provide a pontoon type that combines the water intake of the pontoon with the coarse filtration device. The water quality purification water intake device improves the raw water quality and guarantees the stability and improvement of the influent water quality of the water treatment plant
