Problems solved by technology

[0010] Therefore, as far as the treatment of the entire water body is concerned, the key to comprehensive water treatment lies in the purification and restoration of the water body, and the technology of water body purification and restoration is the key to the final realization of the restoration of water body ecology and self-purification function. Disadvantages, can not fundamentally achieve the above purpose

Embodiment 1

[0025] A specific embodiment of this device is as follows, as figure 2 Shown:

[0026] A non-navigable river flowing into Yangcheng Lake in Xiangcheng District, Suzhou City. The length of the river in the project implementation section is 1200m, the width is 30-40m, the water depth is 1.8-2.5m, and the average flow velocity of the river is 1.2 / s. Using the effective waters of the river, 20 sets of floating solar water purification devices with a length of 60m and a width of 15m are installed at intervals, and the oxygenation capacity of a single device is 300m 3 / h, the solar power is 5kW, and the water in the river is purified for 24 hours continuously. The implementation of this project case has made the COD in the river water Mn , NH 3 -The level of N and TN has risen from the inferior V level before the installation to the IV level, which greatly reduces the pollution of the rivers entering the lake.

Embodiment 2

[0028] Another specific embodiment of the device is as follows, as image 3 Shown:

[0029] An artificial landscape lake in Shanghai, with a water area of ​​about 56,000m 2 , the water depth is 0.9~1.5m, COD Mn , NH 3 -N, TN, and TP are in inferior V level, blue-green algae are overgrown, and they are in a serious eutrophication state. Floating solar water purification devices with a diameter of 4m are installed at multiple points on the lake. The oxygenation capacity of a single device is 100L / min, and the solar power is 0.75kw. It purifies the water in the river continuously for 24 hours. After 70 days of treatment, the landscape lake water body COD Mn Drop below 12mg / L, NH 3 -N and TN reach the standard of Class III water body, and the concentration of TP also drops to about 0.4mg / L.

Abstract

The invention relates to a floating type solar water purification device. The water purification device is composed of a solar power supply device, a floating body device and an oxygen filling device. The solar power supply device comprises a solar panel and a solar power supply. The floating body device comprises a floating raft and a bio carrier constructed on the floating raft. The oxygen filling device comprises an air pump, a pipeline and an oxygen filling-raiser. The whole purification device is freely floating on water surface, the solar energy power supply device is arranged on the floating raft, and the bio carrier and the oxygen filling-raiser are immerged in the water. The solar power supply continuously provides power for the air pump, and the air pump blows air into the oxygen filling-raiser to provide oxygen for the bio carrier. Microorganisms growing on the bio carrier can degrade contaminants in the water under aerobic or anoxic environment to purify the water. Compared with the prior art, the floating type solar water purification device can solve power sources and consumption of water purification facilities, and offshore or in situ purification of surface water in rivers, lakes, reservoirs and the like can be achieved.

Description

technical field [0001] The invention relates to a device in the technical field of environmental protection, in particular to a floating solar water body purification device, which is used for off-shore or on-site purification of surface water bodies such as rivers, lakes or reservoirs. Background technique [0002] The 2011 Bulletin on the State of the Environment in China pointed out that the surface water quality in my country is generally slightly polluted, and the problem of eutrophication in lakes is prominent. [0003] In terms of rivers, among the 469 nationally controlled sections monitored by the ten major water systems of the Yangtze River, the Yellow River, the Pearl River, the Songhua River, the Huaihe River, the Haihe River, the Liaohe River, the rivers in Zhejiang and Fujian, the rivers in Southwest China, and the inland rivers, Class I-III, IV-V The proportions of sections with water quality of Grade V or worse than Grade V were 61.0%, 25.3% and 13.7%, respec...
