Abstract

The invention discloses an anodic protection type automatic descaling salt-containing organic wastewater electrolysis device which is characterized in that a first anode a1, a second anode a2, a firstcathode c1 and a second cathode c2 are arranged in an electrolytic cell 1, and the first cathode c1 and the second cathode c2 are arranged between the first anode a1 and the second anode a2; during electrolysis, the first anode a1 and the second anode a2 are connected in parallel and then are connected with the positive electrode of a power supply 10 in series; and the first cathode c1 and the second cathode c2 are connected in parallel and then are connected with the negative electrode of the power supply 10 in series; when the electrodes are reversed, a first anode a1 circuit and a second anode a2 circuit in an original electrolysis circuit are disconnected, the first cathode c1 and the second cathode c2 are alternately connected with the positive electrode and the negative electrode ofthe power supply 10 respectively to serve as the positive electrode and the negative electrode in an electrode reversing circuit, and therefore surface descaling of the first cathode c1 and the second cathode c2 is achieved. The electrolysis device can effectively reduce scaling on the surface of the cathodes, anode loss is avoided, the electrolysis efficiency is high, and the sewage treatment energy consumption is reduced.

Description

technical field [0001] The invention relates to the field of treatment and reuse of salt-containing organic waste water, in particular to an anode protection type salt-containing organic waste water electrolysis device which has the function of reversing poles, can automatically remove the scale body of the pole plate, and avoids anode loss at the same time. Background technique [0002] The composition of produced water in oil and gas fields is relatively complex, not only containing crude oil, mechanical impurities, inorganic salts (high-priced metal ions), but also dissolved a large amount of gas and bacteria. Reservoir acidification is one of the main measures to increase production and injection in oilfields at home and abroad, but it also produces a large amount of iron ions. When the water contains Fe 2+ At the same time, it can promote the growth of sulfate-reducing bacteria (SRB), and black water containing FeS is easy to appear. At the same time, a large amount of...
