Abstract :
Three photochemical catalysis water treatment processes that combined by H2O2 AC, O3 with small current corrugated plating are studied in this paper. The results show that each process has a pretty high COD removal rate , especially the UV/H2O2 /AC process whose removal rate reaches 83.6%. At the same time , the clad layer of the process UV/H2O2 /AC has a good quality , and the treated water can be used directly in the bright plating technique in theory.
