Description
Technical Field

Background
Most waterworks at home and abroad still adopt an old process method of precipitation, filtration and chlorination for disinfection so far to bring rivers into contact
Water or ground water is simply processed into potable water. However, in the face of industrial sewage, agricultural sewage and domestic sewage rampant and flooding into domestic water sources, water works are overwhelmingly unable to take the best. In addition to the additional pollution caused by the fact that tap water reaches the drinking water terminal from a water plant through a water delivery pipe network and a high-rise water storage tank, municipal tap water is dare to be sanitary. Chlorine is widely used in the sterilization of water treatment because it has a strong inactivation effect on pathogenic microorganisms. However, the treated water contains residual chlorine, which can affect and harm the taste of drinking water, human health, food and beverage quality, ion exchange and membrane separation technical equipment. In particular, chlorination of tap water is effective in killing germs, but also produces a large amount of halogenated hydrocarbon compounds, and the content of chlorinated organic compounds is multiplied, which is a serious source of various diseases for human beings. Even if tap water is boiled, the residues are still remained, and carcinogens such as nitrite and chloroform are increased. The removal of residual chlorine from water has become an important issue in order to avoid the harm caused by residual chlorine. The existing water quality purification products or wading products which take city tap water as source water are basically physical treatment processes of medium adsorption or interception and filtration of pollutants in water by adopting various aperture filter membranes. Since the activated carbon-based adsorption material is easily saturated and fails, and various filter membranes are easily clogged or damaged by bacteria or organic matters, the actual situation cannot be as expected by the theoretical design to sufficiently purify the pollutants in the water. In the face of increasingly serious source water pollution, the existing physical water treatment process for intercepting and filtering pollutants in water by medium adsorption or by adopting various aperture filtering membranes is far from ensuring that the water quality reaches the standard.
The ultrasonic wave is sound wave with frequency more than 20kHz, has high frequency and short wavelength, has the characteristics of good directivity, high power, strong penetrating power and the like, and can also cause cavitation and a series of special effects, such as mechanical effect, thermal effect, chemical effect and the like. In the 30 s of the 20 th century, the first use of ultrasonic cavitation to degas liquids and liquid metals was proposed. Ultrasonic waves are transmitted in liquid, pressure fluctuation can be generated in space and time, and a negative pressure phenomenon occurs. In the negative pressure region, acoustic cavitation occurs and microbubbles are formed. Under the action of ultrasound, a series of dynamic processes of cavitation bubbles occur: oscillate, expand, contract, or even collapse. These activities generate thousands of high temperatures and thousands of atmospheres of high pressure inside the cavitation bubbles. This accelerates the decomposition of hypochlorous acid in the water. At the same time, the ultrasound causes chlorine and oxygen to gradually penetrate into the cavitation bubbles and to be detached from the water by means of the ultrasonic degassing effect, which further promotes the decomposition of hypochlorous acid.
The utility model discloses utilize the supersound to remove surplus chlorine in the aquatic and kill the microorganism, utilize the cavitation effect of supersound, make safe, the high efficiency of getting rid of surplus chlorine, purifying water matter and becoming. Meanwhile, multi-stage filtration is carried out after ultrasonic treatment, so that the service life of the filter element of the filtering clapboard is prolonged, and the quality of water purification is ensured.
