Embodiment 1

[0010] Embodiment 1 takes thiazolines as the example of monosodium glutamate production wastewater mainly polluted. The flow rate of the water medium through the high boron-doped diamond film electrode wastewater treatment device is 10ml / S and 15ml / S respectively, the applied voltage is DC 10V, and the electrode current is 1A respectively. The inspection of the chemical plant confirmed that the COD value of the waste water from the original monosodium glutamate plant was 10 4 mg / ml, while the COD value after passing through the high boron-doped diamond film electrode wastewater treatment device is 2×10 3 mg / ml and 9×10 3 mg / ml. The remaining COD value is mainly due to the harmless sodium chloride contained in the wastewater.

Embodiment 2

[0011] Embodiment 2 is an example with sulfide as the main pollution of dye factory production wastewater. The flow rate of the water medium through the high boron-doped diamond membrane electrode wastewater treatment device is 15ml / S, the applied voltage is DC 10V, and the electrode current is 0.9A. Through the inspection of the dye factory, it was confirmed that the COD value of the original production wastewater was 9×10 3 mg / ml, while the COD value after passing through the high boron-doped diamond film electrode water treatment device is 1.2×10 3 mg / ml. The remaining COD value is mainly due to the harmless sodium chloride contained in the wastewater.

[0012] Electrochemistry has a wide range of applications in the treatment of harmful wastewater, especially the high boron doped diamond film electrode, which is becoming a material to replace traditional electrodes due to its excellent electrochemical properties, and is a field with broad prospects. The application of h...

Abstract

A process for removing the pollutants from industrial sewage by efficient electrochemical oxidizing and decomposing method is disclosed. It features that the membrane electrode of diamond is used to degradate the organic pollutants. Its advantages are high and stable chemical performance, high electric potential and low cost.

Description

technical field [0001] The invention belongs to the field of environmental protection technology treatment, and in particular relates to a technology and a device for treating harmful waste water. Background technique [0002] With the rapid growth of worldwide pollution, environmental protection and resource conservation have become the main direction of future technological development. At present, the protection of water resources has increasingly become the focus of attention. Organic chemical pollution is an important part of harmful wastewater pollution sources (main technical indicator COD-chemical oxygen demand). At present, the main treatment method is biodegradation technology, but the treatment speed is slow and cannot adapt to high concentration pollution. Electrochemical oxidation treatment plays a very important role in the treatment of industrial wastewater. The oxidation process has attracted more and more attention in terms of reducing toxic pollution or a...
