摘要：
Oxidative cleaning of reverse osmosis membranes fouled by steel industry secondary effluent has been investigated. The foulants were characterized by means of EDX and FTIR, and we found that the organics and metal oxide were deposited on the membrane surface. H2O2 (pH=12.0) was selected to regenerate the fouled membrane. Considering the membrane resistance values, the cleaning kinetic was illustrated by Langmuir-Hinshelwood kinetics model.
