Technical Field
The utility model relates to a sterilization device, in particular to a stirring ultraviolet sterilization device for geothermal recharge water.
Background
The geothermal water is extracted and subjected to heat exchange by a secondary heat exchanger to generate a large amount of geothermal wastewater. Because geothermal wastewater contains high salinity and chemical components contained in the geothermal wastewater are toxic and harmful, if a large amount of geothermal wastewater is discharged, the problem of serious environmental pollution is caused, and meanwhile, the water level of geothermal water is reduced in the past, so that the heat storage and production capacity is reduced. If the geothermal waste water is re-filled to the heat storage, not only the environmental pollution can be avoided, but also the heat production capacity of the heat storage can be maintained. After geothermal water is mined from the ground, the geothermal water is subjected to chemical reaction precipitation due to the change of conditions such as temperature, pressure and the like, and suspended particles, microorganisms and the like carried by the geothermal water can directly cause the blockage of the geothermal wastewater recharging process. The microorganism propagation can block a heat reservoir, and iron bacteria contained in geothermal wastewater can aggravate the corrosion of a pipeline and influence the normal recharging process.
At present, the sterilization method in the geothermal tail water recharging process is to add a sterilization agent into water or to remove bacteria by adopting an ultrafiltration membrane for filtration. However, both methods have disadvantages, and the use of the bactericide may pollute the underground water on one hand and cause the bacteria to have problems of drug resistance and the like on the other hand; and the ultrafiltration mode requires large matched ultrafiltration equipment, so that the equipment investment is large and the occupied area is large.
