The intensification of wastewater treatment using combined ozonation and Fenton process (O₃/Fe ²⁺/H₂O₂) for removal of toxic heavy metals such as Lead, Chromium (VI), Zinc, and Manganese in actual municipal wastewater was investigated. RSM was used to optimize process parameters viz. ozone concentration, initial pH, Fe (II), and H₂O₂ concentration. The high value of the coefficient of determination (R² =0.9793 for Pb; 0.9824 for Zn; 0.9735 for Mn; 0.9724 for Cr (VI)) confirms that RSM effectively predicted the performance of the O₃/Fe ²⁺/H₂O₂ process. The heavy metal removal efficiency of 98.66% for Pb, 99.22% for Zn, 95.11% for Mn, and 94.55% for Cr (VI) obtained at optimized conditions were comparable with RSM predicted efficiencies. The present intensification approach has enhanced the treatment efficiency and was found to be cost-effective than ozonation.

研究了采用臭氧化和Fenton工艺（O ₃ / Fe ²⁺ / H ₂ O ₂）联合处理废水的强化处理，以去除实际市政废水中的铅，铬（VI），锌和锰等有毒重金属。RSM用于优化工艺参数，即。臭氧浓度，初始pH值，Fe（II）和H ₂ O ₂浓度。测定系数的高值（铅的R ² = 0.9793；锌的0.9824；锰的0.9735；铬（VI）的0.9724）证实RSM有效地预测了O ₃ / Fe ²⁺ / H ₂ O的性能。_2个过程。在优化条件下获得的重金属去除率分别为98.66％（铅），99.22％（锌），95.11％（锰）和94.55％（铬（VI）），与RSM预测的效率相当。本发明的强化方法提高了治疗效率，并且发现其比臭氧化更具成本效益。
