Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0033] Such as figure 1 As shown, an electrolytic treatment device for organic wastewater includes a reactor and a power supply. The reactor is provided with a plurality of connected reaction chambers. The water inlet and the water outlet are respectively connected to the two outermost reaction chambers. There is a diversion hole for the flow of waste water between the two reaction chambers, and the reaction chamber is covered with a top cover; the current is kept at a constant current of 10A through the regulation of the power supply.

[0034] The reaction chamber includes at least two electrolysis chambers. Different types of electrode pairs are arranged in the electrolysis chambers, and the electrode pairs are connected to the power supply through connecting wires. At least one reaction ch...

Abstract

The invention discloses a device and a method for electrolytic treatment of acid organic wastewater with high salinity. The device comprises a reactor and a power supply, wherein the reactor is provided with a plurality of reaction chambers which are connected; a water inlet and a water outlet are respectively connected with the reaction chambers on the outermost sides; a flow guide hole for wastewater flow is formed between each two adjacent reaction chambers; and top covers cover the reaction chambers. The reaction chambers comprise at least two electrolytic chambers, wherein different types of electrode couples are arranged in the electrolytic chambers and are connected with the power supply through connecting lines, and at least one reaction chamber used as a homogeneous pool or a buffer chamber is arranged between the electrolytic chambers. According to the invention, a multistage-electrode electrolysis combining method is adopted to improve the electrolytic efficiency of different pollutants, so that the pollutants in the wastewater are degraded to a maximum extent, and the concentration of chloride ions is lowered and the acidity is neutralized at the same time. Therefore, the multifunction of an electrolytic reaction is realized. Besides, based on a multistage continuous electrolytic reaction, the pollutants can be removed more thoroughly, and the removal efficiency is higher.

Description

technical field [0001] The invention belongs to the technical field of wastewater electrolytic treatment, and relates to an electrolytic treatment device and method for high-salinity acidic organic wastewater. Background technique [0002] With the rapid development of my country's industry, a large amount of waste water is produced at the same time, most of which are refractory organic waste water, such as synthetic dyes, synthetic pharmaceuticals, petrochemical waste water, printing and dyeing, waste water produced by chlor-alkali industry, etc. The organic composition of these waste water is complex, so for waste water The ingredients are different, and the processing method should be selected according to its ingredients. Among them, waste water with high salinity (mainly chlorine salt), high COD, high chroma, high toxicity, and low pH value cannot be directly treated by biochemical methods. Coagulation and sedimentation can transfer pollutants from water to sediment , b...
