Wave-energy aeration, flocculation and purification device

Abstract

The invention belongs to the technical field of energy conservation and emission reduction, and relates to a wave-energy aeration, flocculation and purification device which comprises a buoy. The upper side of the buoy is fixedly connected with a protective shell, a connecting rod is fixed to the top of the protective shell, a coil is connected with the connecting rod and can swing along with the connecting rod, the wall surface of the protective shell is surrounded by a permanent magnet, the coil can swing along with the connecting rod under the effect of waves to cut magnetic induction lines so as to generate power, and is connected with an alternating-current and direct-current converter by a conducting wire, an aeration pump and a storage battery are respectively connected to the lower side of the alternating-current and direct-current converter, the storage battery is connected with the aeration pump, a polymeric flocculant and polyaluminum chloride release layer is arranged inside the buoy, and the alternating-current and direct-current converter, the storage battery and the aeration pump are arranged in the buoy; a flocculant layer is further arranged in the buoy, is positioned below the storage battery and is provided with a release opening formed in the outer wall of the buoy, and the release opening of the flocculant layer can be opened or closed under the control of the storage battery; the bottom of the buoy is connected with a bottom counterweight by a tied rope. The wave-energy aeration, flocculation and purification device has the advantages of good aeration and flocculation coupling effects, high efficiency and feasibility.

Description

technical field [0001] The invention belongs to the technical field of energy saving and emission reduction, and relates to a wave energy aeration flocculation purification device. Background technique [0002] my country is a country seriously short of water, the total amount of water resources is not rich, the total amount of fresh water resources is 28000 [0003] billion m3, ranking sixth in the world, while the per capita water resource utilization is about 900 m3, which is only a quarter of the world's per capita water resources. More than 400 of the more than 600 cities in the country have insufficient water supply. In addition to the lack of water resources, with the development of economy and society, China has gradually fallen into a serious water quality crisis, and water pollution has become one of the important ecological and environmental problems in China and the world. The causes of China's water pollution are complex, wide-ranging and large-scale, with man...

Problems solved by technology

Although the effect of the activated carbon method is better, it is not suitable for large-scale use because of the high cost

[0013] Biological methods include aquatic biology method and aquatic plant method, but both will cause the invasion of other species and eventually destroy the ecological balance
