Embodiment Construction

[0038] The discharge reaction chamber (7) of the reactor is filled with metal particles (6), and new metal particles (6) are added to the discharge reaction chamber (7) according to the wear degree of the metal particles (6). The sewage is pumped into the reactor (10) through the water inlet (1), the water inlet chamber (11) and the water inlet channel (5) by the water pump at a flow rate of 2 tons per hour. Impurities contained in sewage (mg / liter): Cr 6+ : 37.8, Cu 2+ : 20.0, Zn 2+ : 19.0, Ni 2+ : 28.5, Sn 2+ , Sn 4+ : 10.0, CN - : 13.5, the total pollutant content of sewage is 128.8 mg / liter, and the pH value of water is 3.8. The applied pulse voltages are 700V and 200V, the corresponding pulse currents are 250A and 800A, the pulse energy is 7J, and the average power is 0.6KW. Sewage is discharged into the sedimentation chamber after being treated by the reactor (10), and a sample is taken for detection after 10 minutes. The residual concentration of impurities in th...

Abstract

A process for treating sewage by electric pulse micro plasma features that the sewage is loaded in a reactor equipped with metallic load, and electric pulses are applied to it. Its apparatus is composed of a reactor and a current pulse generator. It can remove various pollutants including heavy metals, petrochemical pollutant, lubricating coolant, organic substance, toxin, microbes, etc..

Description

Technical field [0001] The invention belongs to the application technical field of the combination of plasma physics and plasma chemistry, in particular to an electric pulse micro-plasma water treatment method and equipment. Background technique [0002] There are many existing methods and technologies for sewage treatment and water sterilization and disinfection, including physical methods using membrane filtration and ultraviolet irradiation; chemical methods using redox agents and bactericides, and biochemical methods for microorganisms. These methods all use a certain function to act on specific components in water alone, and cannot treat water comprehensively. For example, the microorganisms used in the biochemical method can decompose the organic components in the water, but they are powerless to the heavy metals in the water. At the same time, these methods also have problems such as high processing cost (such as membrane filtration method), secondary pollution (such...
