Abstract
The invention discloses an electric hydroxyl oxidation purification device and method for acetone-containing production wastewater. The invention belongs to the field of chemical engineering and technology. According to the invention, a 108L reactor is designed and manufactured and is used for treating and researching water with acetone content of 15000 ppm / L; wherein the current intensity is changed by adjusting the alternating-current voltage, so that the influences of the current intensity, the reaction time, the oxygen introduction amount, the pH value of the solution and the temperature change on acetone removal are measured respectively; therefore, optimal removal rate condition is obtained, and the technical defects that in the prior art, the acetone-containing wastewater treatmentprocess is long, the treatment time is long, a treatment pool is large, the treatment efficiency is low, and the solid waste generation amount is large are overcome.
Description
technical field [0001] The invention belongs to the field of chemical engineering and technology, and in particular relates to an electro-oxygen oxidation purification method for acetone-containing production wastewater. Background technique [0002] Due to the needs of the process in production, acetone and water are mixed, and most of the acetone is recovered through rectification. However, when the concentration of acetone is low, water and acetone are evaporated at the same time. Therefore, the remaining water after distillation still contains tens of thousands of ppm of acetone. Acetone is an organic matter, which affects the COD index of chemical oxygen demand in the discharged water. [0003] There are many ways to remove organic matter in water in industry, such as flocculation sedimentation, chemical sedimentation, hydroxyl oxidation, anaerobic aerobic and other methods, each of which has its own advantages and disadvantages. [0004] With the development of indus...
