Oil-containing chemical waste water treatment equipment and treatment method

Abstract

The invention discloses oil-containing chemical waste water treatment equipment and a treatment method. The oil-containing chemical waste water treatment equipment comprises a power source, a reaction device, a shaft type negative pole, a spiral positive pole, an air floating device and a biochemical treatment device; the shaft type negative pole is vertically fixed to the center of a cylindrical reaction part through a negative pole fixing device, and the top end of the shaft type negative pole is connected with a negative pole of the power source through a wire; the periphery of the shaft type negative pole is sleeved with a rotatable positive pole fixing device, the spiral positive pole comprises multiple conducting blades, and the conducting blades are spirally distributed on the outer wall face of the positive pole fixing device; the air floating device is connected with a reaction water outlet; the biochemical treatment device is connected with an air floating water outlet. The collaborative coupling function of all processes can be achieved in the same reaction device, the processes complement and promote one another, defects when the processes respectively take effect are overcome, the treatment effect is improved remarkably, energy consumption is reduced, the structure of the reaction device is optimized, and the occupied area is reduced.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to equipment and a treatment method for oily chemical wastewater. Background technique [0002] In recent years, with the continuous development of the economy, industrial wastewater, especially chemical wastewater, has become more and more serious to the environment. Wastewater discharged after incomplete treatment will threaten human health and ecological security. [0003] Chemical wastewater often has complex components and contains a large number of refractory components. Traditional sewage treatment technologies are difficult to achieve satisfactory treatment results, and the process is complex, with high energy consumption, large volume, and long time-consuming. Therefore, treatment equipment and technology with small size, high efficiency and easy operation have always been a difficult point and research hotspot in water treatment work at home and abroad. [0004] For oily wa...

AI Technical Summary

Problems solved by technology

However, it is difficult to remove solid impurities in water electrochemically. Gas-liquid mixing is slow in the electrochemical air flotation process. The generation of bubbles is greatly affected by the area and position of the electrode. The redox degradation of pollutants in the water on the electrode surface is affected by mass transfer. It has a large impact and is often difficult to be degraded when it is not in contact with the electrode

[0006] The traditional wastewater treatment technology generally purifies water quality through the series operation of multiple processes and the combined application of multiple processes, but this brings problems such as large footprint and cumbersome operation and management.
