Efficient electrochemical water treatment technology and device

Abstract

The invention discloses an efficient electrochemical water treatment device. The device comprises an electrolytic tank, a water inlet is formed in one side edge of the electrolytic tank, and a pumping-suction port is formed in the other side edge, of the portion which forms 90 degrees with the water inlet, of the electrolytic tank; electrode plates are symmetrically arranged at the left and rightsides in the electrolytic tank respectively, the electrolytic tank and the electrode plates are fixedly connected through connection mechanisms, and a control mechanism is arranged below the pumping-suction port; each electrode plate comprises a connector, an electrode plate inner ring and an electrode outer ring, and each electrode outer ring is arranged on the outer portion of the correspondingelectrode plate inner ring. According to the device, a circuit switching module is used for controlling the positive and negative polarity of the electrode plate inner rings and the electrode outer rings to be switched in a certain time interval, the positive electrode turns to be the negative electrode, the negative electrode turns to be the positive electrode, a scale layer formed in the surfaceof each negative electrode is dissolved and falls off under the last polarity condition, so that the surface of the electrode is regenerated, and the electrolytic tank always keeps to work at high efficiency.

Description

technical field [0001] The invention belongs to the technical field of high-efficiency wastewater treatment, and in particular relates to a high-efficiency electrochemical water treatment process and treatment equipment. Background technique [0002] Today, with the rapid development of industry, the discharge of wastewater is also increasing, especially in chemical, pesticide, petrochemical, coking and other related industries. The wastewater produced by it is very serious to the environment, and the reasons for these pollution are mainly Because there are too many toxic substances in wastewater, such as high-concentration chemical substances and chemical substances with large chromaticity, the commonly used wastewater treatment methods are mainly physical treatment, biological treatment and chemical treatment. When these methods are used, once they are not handled properly, It is very easy to cause secondary environmental pollution. Based on this, the application and popul...

Problems solved by technology

[0002] Today, with the rapid development of industry, the discharge of wastewater is also increasing, especially in chemical, pesticide, petrochemical, coking and other related industries. The wastewater produced by it is very serious to the environment, and the reasons for these pollution are mainly Because there are too many toxic substances in wastewater, such as high-concentration chemical substances and chemical substances with large chromaticity, the commonly used wastewater treatment methods are mainly physical treatment, biological treatment and chemical treatment. When these methods are used, once they are not handled properly, It is very easy to cause secondary environmental pollution. Based on this, the application and popularization of electrochemical wastewater treatment methods is very important. The electrochemical treatment method is mainly aimed at some organic and inorganic pollutants that are difficult to decompose. The functions of the processing equipment are improving day by day, but there are still some deficiencies to be improved

[0003] The electrochemical treatment equipment of the prior art has the following problems: 1. After the cathode of the existing electrochemical treatment equipment has been used for a period of time, a fouling layer will be produced, which will lead to a decrease in the hydrolysis current, an increase in power consumption, and a significant drop in efficiency. Affect the treatment effect of wastewater; 2. The cathode and anode of the electrochemical treatment equipment currently on the market have a limited service life. In order to ensure the treatment efficiency of the cathode and anode, it needs to be maintained or replaced regularly. Most of the processing equipment has an integrated structure, which is inconvenient to maintain or replace
