Problems solved by technology

[0004] (1) The inertness is not good, the electrochemical window is too narrow, the reproducibility and stability of the electrode are poor, and the steady-state current response time is long, so the electrode life is short, and the sewage treatment efficiency and removal rate are low
[0005] (2) The electrochemical oxidation index of the electrode is low, and the performance of the electrode is not good. Sometimes the refractory substances cannot be completely oxidized, and can only be oxidized into less toxic substances that are easy to biodegrade; sometimes the intermediate products produced are more toxic than the original target substances. more toxic
[0010] The electrolyzers with various structures above also have the disadvantage that the efficiency of sewage treatment is not high enough

Embodiment Construction

[0021] The electrolyzer that the present invention proposes is used for refractory sewage treatment, and its structure is as follows figure 1 As shown, it includes an upper cover 5, a lower cover 1, an upper base 4, a lower base and a plurality of electrodes. The upper cover 5 and the lower cover 1 are sealed and connected to each other to form the inner cavity of the electrolytic cell. The upper cover 5 and the lower cover 1 are respectively provided with electrode terminals 6 and water pipe joints 9 . The electrode terminal 6 and the base 4 are linked with each other through the adjustment nuts 7 and 8, and the upper and lower bases 4 are bonded to the adjacent electrodes. Coaxial installation, with gaskets 10 between the electrodes.

[0022] The electrode 3 bonded to the base electrode 4 in the above-mentioned electrolytic cell is a single-sided metal-doped diamond film electrode, and the other electrodes, as shown in the figure, electrode 2 are double-sided metal-doped di...

Abstract

This invention relates to an electrolytic bath used in processing polluted water including a top cover, bottom cover, a upper base, a lower base and multiple electrodes. The two covers are enclosed mutually to form an inner cavity and electrode wiring terminals and water pipe joints are set on the two covers separately. The terminals and the base are inter-linked by adjusting screws, the two bases are adhered with adjacent electrodes, the multiple electrodes are parallel in the inner cavity of the electrolytic bath mounted with the terminals coaxially, pads are set between the electrodes.

Description

technical field [0001] The invention relates to an electrolytic cell for sewage treatment, in particular to an electrolytic cell for sewage treatment using a metal-doped diamond film as an electrode, and belongs to the technical field of environmental treatment. Background technique [0002] With the rapid development of the economy and the rapid increase of the population, the discharge of wastewater is increasing day by day, and the environmental pollution is becoming more and more serious. Environmental protection and resource protection have become the main problems and key factors of economic development. my country is a water-scarce country, and the increasingly serious water pollution is tantamount to worsening the situation, making a considerable part of the originally limited water resources lose their use value. Due to the heavy metals, compounds and organic wastewater in sewage, especially the high-concentration wastewater discharged from industries such as chemic...
