Problems solved by technology

[0003] A lot of organic wastewater that is difficult to decompose needs to be treated by electrolysis, but the speed of ordinary organic wastewater electrolysis is slow, and the sewage is easy to adhere to the electrode plate, which affects the electrolysis speed. Therefore, we propose a method for organic wastewater treatment. Electrochemical Treatment of Wastewater

Embodiment 1

[0032] 1. An electrochemical treatment method for organic waste water, comprising the steps of:

[0033] S1, check the equipment, confirm that the driving motor 16, the ultrasonic generator 7, the air pump 3 and the drain valve 61 are normal;

[0034] S2, add pure water, inject pure water into the pure water area 9 at both ends of the insulating water tank 1, open the ultrasonic generator 7, and start working;

[0035] S3. Sewage injection. The sewage is guided into the insulating water tank 1 through the water inlet pipe 11. When the water level reaches half of the inner depth of the insulating water tank 1, the air pump 3 is turned on for aeration;

[0036] S4, energize, turn on the power supply to energize the wave-shaped anode electrode plate 5 and the wave-shaped cathode electrode plate 10 respectively;

[0037] S5, dosing, drop into environment-friendly ultrasonic cleaning liquid and antiscalant from water inlet pipe 11;

[0038] S4, start the drive motor 16, adjust th...

Abstract

The invention discloses an electrochemical treatment method for organic waste water. The electrochemical treatment method for the organic waste water comprises the following steps: S1, checking equipment; S2, adding pure water: injecting the pure water to pure water areas at the two ends of the interior of an insulated water tank; S3, injecting sewage: guiding the sewage into the insulated water tank via a water inlet pipe; S4, electrifying: switching on a power supply to enable a wavy anode plate and a wavy cathode plate to be correspondingly electrified; S5, putting chemicals: putting an environmentally friendly ultrasonic cleaning fluid and a scale inhibitor from a water inlet pipe; S4, starting a driving motor and adjusting forward and backward rotation angles and frequencies of the driving motor; S5, opening a water drain valve to electrolyze the organic waste water in circulation to achieve a purpose of treating the organic waste water. The electrochemical treatment method for the organic waste water, disclosed by the invention, has the advantages that the electrolysis speed of the sewage is increased to increase the sewage treatment speed by using an aeration pipe and an ultrasonic generator to vibrate the sewage; and in the sewage flowing process, the contact areas between the sewage and the electrode plates are increased, and the sewage electrolysis speed is increased.

Description

technical field [0001] The invention belongs to the technical field of organic wastewater treatment, and more specifically relates to an electrochemical treatment method for organic wastewater. Background technique [0002] Organic wastewater is wastewater mainly composed of organic pollutants. Organic wastewater is likely to cause eutrophication of water quality and is relatively harmful. Organic wastewater generally refers to the wastewater discharged from printing and dyeing, papermaking, leather and food industries with a concentration of more than 2000mg / L. Industrial wastewater such as textile printing and dyeing, domestic sewage, food processing, and papermaking contains organic substances such as dyes, carbohydrates, proteins, oils, and lignin. These substances exist in the sewage in a suspended or dissolved state and can be decomposed by the biochemical action of microorganisms. Oxygen-depleting pollutants are called oxygen-depleting pollutants because they consum...
