Abstract

The invention discloses a three-dimensional electrochemical coupled baffle anaerobic reactor water treatment device which comprises a three-dimensional electrochemical reactor and a baffle anaerobic reactor connected with the three-dimensional electrochemical reactor, wherein an electrolytic cell is arranged in the three-dimensional electrochemical reactor; the electrolytic cell comprises an anodeplate and a cathode plate of which two ends are respectively arranged; a plurality of particle electrodes are arranged between the anode plate and the cathode plate; a stirrer is arranged on the electrolytic cell; a stirring rotor on the stirrer penetrates through the plurality of particle electrodes; a water inlet is formed in the three-dimensional electrochemical reactor; a water outlet is formed in the baffle anaerobic reactor; a circulating pipeline is arranged between the water outlet end of the baffle anaerobic reactor and the three-dimensional electrochemical reactor. The invention further discloses a sewage treatment method by utilizing the device. Sewage passes through the two reactors, high-concentration organic sewage, low C / N livestock breeding sewage and high-salt toxic chemical wastewater can be effectively treated, the effluent quality is stable, and the advantages of energy conservation and consumption reduction are obvious.

Description

Technical field [0001] The invention relates to the field of sewage treatment, in particular to a three-dimensional electrochemical coupling baffle anaerobic reactor water treatment device and a sewage treatment method thereof. Background technique [0002] Nowadays, with various low-C / N livestock and poultry farming sewage and various high-salt and toxic chemical sewage, it is difficult for the simple anaerobic reaction process to meet the corresponding treatment requirements, and the treatment efficiency is low. As a current research hotspot, three-dimensional electrochemistry can effectively treat C / N sewage and high-salt and toxic chemical sewage. At the same time, it also faces some problems. The effluent is difficult to discharge and needs to be combined with other processes. The particle electrode is easy to compact. The temperature of the outlet water is too high, causing energy waste and so on. To a large extent, the practical application of three-dimensional electroche...

AI Technical Summary

Problems solved by technology

[0002] Nowadays, with various low C / N livestock and poultry breeding sewage and various high-salt and toxic chemical sewage, it is difficult for the simple anaerobic reaction process to meet the corresponding treatment requirements, and the treatment efficiency is low

As a current research hotspot, three-dimensional electrochemistry can effectively treat C / N sewage and high-salt and toxic chemical sewage. At the same time, it also faces some problems. It is difficult to discharge the effluent up to the standard. It needs to be combined with other processes. The outlet water temperature is too high, resulting in waste of energy, etc.

Practical applications of 3D electrochemistry are largely limited

At present, in the field of sewage treatment, there is no sewage treatment device that directly combines anaerobic reaction process with three-dimensional electrochemical treatment.
