Embodiment 1

[0029] After passing water into the reaction vessel, turn on the DC power supply, apply 400V voltage to the cathode and anode, and electrolytic reaction occurs in the reaction vessel. Continue to increase the voltage to 500-1500V, the gas at the small hole is broken down, and plasma is formed to treat the influent water.

[0030] Experimental conditions: the volume of the container is 1L; the initial concentration of E. coli is 10 3 CFU / ml; phenol concentration 2mg / l; initial pH 6.5; silver ion concentration 3mg / L; current 25mA, voltage 500-1500V, constant current mode.

[0031] Detection conditions: Escherichia coli is determined by counting method, phenol concentration is determined by high performance liquid chromatography, pH is measured by acidity meter, and silver ion concentration is determined by atomic absorption method. The obtained data are shown in Table 1.

Abstract

The invention relates to a method for processing drinking water and a device using the same, relating to water treatment. A drinking water processing device and a drinking water processing method are provided. The processing device is provided with a reactor, a cathode, an anode, a diaphragm and a power supply. The cathode and the anode are arranged in the reactor and fixed on an electrode carrier which is arranged on the upper part of the reactor; the bottom of the diaphragm is fixed at the bottom in the reactor, the diaphragm divides the reactor into a cathode zone and an anode zone, the top of the reactor is provided with a water inlet, and the bottom of the reactor is provided with an alkaline water outlet and an acid water outlet. After water is introduced into the reactor, voltage is applied on the cathode and the anode to perform electrochemical reaction, the applied voltage is boosted, thus liquid water at the external micropores of the anode is vaporized with the action of joule heating to form plasma; water is processed, when the retention period of inflow water is larger than 10min, the organic matter, pathogen and heavy metal in water are removed, and weak alkaline water and weak acid water are respectively obtained at the alkaline water outlet and the acid water outlet.

Description

technical field [0001] The invention relates to water treatment, in particular to a drinking water treatment method and a device thereof. Background technique [0002] In recent years, the pollution of drinking water sources in our country has been increasing day by day. If it is directly drunk without effective treatment, it will bring serious harm to people's health. At present, water purification plants mainly adopt the traditional process of "coagulation-filtration-chlorination disinfection", which can effectively remove suspended solids, color and pathogenic bacteria in water, but has limited removal effect on heavy metal ions and dissolved organic matter. Moreover, in the process of chlorination disinfection, organic matter will react with chlorine gas to produce a variety of toxic and harmful by-products, such as trihalomethanes (THMs), haloacetic acids (HAAs), etc. Therefore, it is very important to seek an advanced treatment method for drinking water that can simul...
