反渗透耦合多催化臭氧氧化(RO-MCO)处理印染废水和膜浓缩物:去除性能和机理

在江苏省印染废水集中处理中，面对印染行业对回用的高要求，反渗透（RO）工艺被常规用于废水回用。然而，膜浓缩物盐度高，色度高，成分复杂。臭氧氧化作为一种高效、清洁的高级氧化工艺，应用广泛，但也存在传质和催化效率差等问题。本文设计了一种新型的铝碳基金属掺杂复合臭氧催化剂，并构建了RO耦合多催化氧化法处理生物处理尾水。得到了催化剂用量为0.5 g L−1、臭氧浓度为5 mg L−1和30%H2O2用量为10 mg L−2的最佳工艺参数。经过长期的运行试验，联合工艺已被证明可以实现尾水的安全排放和循环利用，对外部水环境的生态风险较低。

期刊介绍： Water Resources and Industry moves research to innovation by focusing on the role industry plays in the exploitation, management and treatment of water resources. Different industries use radically different water resources in their production processes, while they produce, treat and dispose a wide variety of wastewater qualities. Depending on the geographical location of the facilities, the impact on the local resources will vary, pre-empting the applicability of one single approach. The aims and scope of the journal include: -Industrial water footprint assessment - an evaluation of tools and methodologies -What constitutes good corporate governance and policy and how to evaluate water-related risk -What constitutes good stakeholder collaboration and engagement -New technologies enabling companies to better manage water resources -Integration of water and energy and of water treatment and production processes in industry
