Abstract

The present invention provides a chlorophenol-containing wastewater treatment technology by ultrasonic ozonation, wherein a stainless steel ultrasonic wave reaction tank is adopted, the ozone contacts with the waste water through a pore diffuser fixed at the bottom of the reaction tank, the chlorophenol of the waste water is removed under the condition of a sound wave frequency of 40 kHz, a sound energy density of 50~150 W / L, a ozone amount of 10~30 mg / L.h, a pH value of 8.0~8.2 and a water power residence time in the tank of 60~90 min. In the present invention, by optimizing the technological parameters, the purpose of lower energy consumption, high removing efficiency is realized, and the technology is adapted to the practical chlorophenol-containing wastewater treatment and has excellent market development prospect.

Description

(1) Technical field

[0001] The invention relates to a process for treating chlorine-containing phenol wastewater with ultrasonic ozone. (2) Background technology

[0002] Chlorine-containing organic compounds are widely used in chemical, petrochemical, and pesticide production, and are discharged into the environment in gaseous and liquid forms, resulting in the "three effects". Acoustic, ozone and other advanced oxidation technologies are known as a type of "environmentally friendly" technology because of their good environmental compatibility, which provides a broad prospect for the pollution control of chlorinated organic compounds. Related research and application have been It has aroused widespread attention from domestic and foreign counterparts, especially the combined use of oxidation technology can form a synergistic effect, which represents a development trend of advanced oxidation technology in this field.

[0003] Chlorophenols are a class of pollutants that are...
