Electroflotation/ultraviolet rainwater purification device and use method thereof

Abstract

The invention discloses an electroflotation / ultraviolet rainwater purification device and a use method thereof, and belongs to the field of ecological environment. A liquid level detector, an electrode plate, an ultraviolet lamp tube, a slag suction machine and a water outlet are arranged in the device, rainwater enters the device through a lifting pump, and a flow detector detects flow change in a pipe and controls the water outlet to be closed. The rainwater submerges the liquid level detector, the electrode plate, the ultraviolet lamp tube and the slag suction machine are started after being electrified. The electrode plate electrolyzes and oxidizes rainwater to generate microbubbles capable of adsorbing and wrapping suspended matter particles in water, when floating to the water surface, the microbubbles are removed by the slag suction machine, the electrode plate can directly electrolyze and oxidize organic matter in the water, and meanwhile ultraviolet light can effectively kill pathogen microorganisms in the water body. When the flow detector does not detect the flow change, that is, no rainwater enters the device, the water outlet is controlled to be opened, and the rainwater in the device is completely drained. The device is simple in structure, rainwater purification can be completed without manual control, meanwhile, the sterilization and disinfection effects are achieved, and the device is suitable for various rainwater recycling ways.

Description

technical field [0001] The invention belongs to the field of ecological environment, and in particular relates to a purification device for purifying middle and late rainwater by using electric floating / ultraviolet rays. Background technique [0002] At present, the current situation of my country's water resources is severe, and the problems of water resource shortage, waste, uneven distribution and pollution are becoming more and more prominent, which seriously restricts the sustainable development of my country's economy and society. Rainwater is a high-quality fresh water resource, and its recycling has good ecological, social and economic benefits. However, with the rapid development of China's urbanization process, urban road surface pollution, acid rain pollution and air pollution have become increasingly serious, and various water sources including rainwater have been seriously polluted. In the process of resource utilization of rainwater, although the initial rainw...

Problems solved by technology

[0004] Aiming at the current mid-to-late stage rainwater purification devices on the market, the device functions are single and the purification process is relatively cumbersome, and the follow-up sterilization and disinfection process mostly adopts the method of adding chemical agents, which easily leads to the problem of secondary pollution of the water body
