Description

technical field [0001] The invention relates to the technical field of deuterium-depleted water production, in particular to a deuterium-depleted water wastewater recycling device and method. Background technique [0002] Deuterium-depleted water refers to water with a deuterium content lower than 150ppm. Experimental studies have shown that deuterium-depleted water has a variety of biological effects beneficial to the human body: such as activating human cells, enhancing human immunity, and preventing cancer and health care. The large-scale production methods of deuterium-depleted water mainly include electrolysis, distillation and water / hydrogen dual-temperature exchange method. Among them, the distillation method is widely used because it does not require the use of catalysts or chemical reagents, and the production process is simple and mature. The distillation method to prepare deuterium-depleted water is carried out in a distillation tower equipped with several trays o...

AI Technical Summary

Problems solved by technology

However, the existing distillation production equipment for deuterium-depleted water has the following technical problems after separation in actual use: high-deuterium water will be produced in the distillation tower, and high-deuterium water is directly discharged as waste water, although Direct discharge will not cause environmental pollution, but it will cause waste of water resources
