Abstract

The application of two different processes simultaneously in a single reactor for the removal of persistent compounds from wastewater provides low investment cost, low treatment time, and synergistic pollutant removal. In this study, Magnetite-Powder Activated Carbon (M-AC) and Calcium Peroxide (CaO₂) were used simultaneously in an adsorption/oxidation hybrid process to remove Reactive Blue 21 (RB21) from simulated textile wastewater. M-AC can be separated for regeneration from the hybrid system by applying a magnetic field. CaO₂ is an eco-friendly, strong oxidant that can be used without any activator. Different amounts of M-AC and CaO₂ were used simultaneously in the hybrid process. The RB21 removal efficiency within 45 min was calculated as 99.44% with the simultaneous use of 0.04 g M-AC and 0.2 g CaO₂. It was found that the M-AC/CaO₂ hybrid system is an effective process to remove color from textile wastewater.

摘要

在单个反应器中同时应用两种不同的工艺来去除废水中的持久性化合物，投资成本低，处理时间短，并且可以协同去除污染物。在本研究中，磁铁矿粉活性炭（M-AC）和过氧化钙（CaO ₂）同时用于吸附/氧化混合工艺中，以去除模拟纺织废水中的活性蓝21（RB21）。通过施加磁场，可以将 M-AC 从混合系统中分离出来进行再生。CaO ₂是一种环保型强氧化剂，无需任何活化剂即可使用。不同量的M-AC和CaO ₂在混合过程中同时使用。同时使用0.04 g M-AC和0.2 g CaO ₂时，计算出45 min内RB21去除效率为99.44% 。结果发现，M-AC/CaO ₂混合系统是去除纺织废水中颜色的有效工艺。
