Chlorine has a strong inactivation effect on pathogenic microorganisms, so that the chlorine is widely used in a sterilization link of water treatment. However, the treated water contains residual chlorine, which can affect and damage drinking water taste, human health, food and beverage quality, ion exchange and membrane separation technical equipment. In particular, tap water is chlorinated, although effective in killing germs, more halogenated hydrocarbon compounds are produced at the same time, and the content of chlorine-containing organic matters is multiplied, so that the chlorinated tap water is a major source for various diseases of human beings. The main purpose of the chlorination of public water is to prevent water from spreading diseases, the method is popularized to the past 110 years, has more perfect production technology and equipment, and most of domestic and foreign water works still adopt the technological methods of precipitation, filtration and chlorination so far, and river water or underground water is simply processed into potable water.
The residual chlorine-containing water can damage the nutrient components such as vitamins, minerals and the like in vegetables, fruits and grains when used for cleaning the vegetables, fruits and grains, and seriously affects the absorption of the nutrient substances by human bodies. The chlorine used in tap water can be absorbed easily and quickly on any oxidized surface layer with capillary holes such as skin, nostril, oral cavity, lung, hair, eyes, meat, vegetables and fruits, etc. Because the skin surface layer of the human body spreads over pores and sweat glands, residual chlorine can easily enter through the fine pores to be absorbed by the human body at the moment of contact with tap water. The bath is carried out by tap water containing residual chlorine, four components in the total amount of chlorine in the bathroom are inhaled through respiratory tract, and the three components are absorbed by skin, 6-8 times of chlorine entering the human body through drinking in general, and the light people generate itching, so that the cancerogenic rate of the people in the middle-aged is increased by 30 percent. After the chlorine is heated, the chlorine and organic humus in water generate cancerogenic substances such as chloroform, the chloroform is increased by 3-4 times than tap water, and if the residual chlorine can not be removed, coffee, tea or soup drunk by people every day is heated and boiled for drinking, and the cancerogenic substances are increased by 3-4 times in the body. The long-term drinking of water containing residual chlorine can greatly increase the incidence of heart diseases, coronary atherosclerosis, anemia, bladder cancer, liver cancer, rectal cancer, hypertension, allergy and other diseases.
In order to avoid the damage caused by residual chlorine, the removal of residual chlorine in water has become an important problem. It is highly desirable to provide a solution for efficiently removing residual chlorine in water.

20. In the 30 s of century, it was first proposed to degas liquids and liquid metals using the ultrasonic cavitation effect. Ultrasonic wave propagates in liquid, pressure fluctuation occurs in time and space, and negative pressure phenomenon occurs. In the negative pressure region, acoustic cavitation occurs and microbubbles are formed. Under the action of ultrasound, cavitation bubbles undergo a series of dynamic processes: oscillation, expansion, contraction or even collapse. These activities can cause high pressures within the cavitation bubbles of thousands of degrees and high temperatures and pressures of thousands of atmospheres. This accelerates hypochlorous acid decomposition in the water. At the same time, ultrasound gradually permeates chlorine and oxygen into cavitation bubbles and is released from the water by means of the ultrasound degassing effect, which further promotes the decomposition of hypochlorous acid.
