Microwave can not only treat pollutants in water, but also kill bacteria, algae and other microorganisms in water. The principle of its action is due to the thermal effect of microwave radiation, that is, the physiological effect and damage caused by the heating of biological tissues and organs when microwave radiation field irradiates organisms. The polar molecules that make up the cell are heated by the external microwave field, which leads to the temperature rise of the biological cell tissue. When the microwave power density is large, the organism produces too much heat, which exceeds the ability of temperature regulation. The temperature balance function of the organism is out of balance, and the body temperature rises, so the organism has physiological dysfunction and pathological changes, and then dies.
