| Abstract: | The pre-chlorination technology was applied for removal of reductive compounds such as cyanide compounds,sulfide and hydrazine hydrate in drinking source water.The performance and influence factors of pre-chlorination technology were studied through the simulating tests.Results showed that the concentration of cyanide was decreased with increasing the active chlorine dosage,when active chlorine>5.0 mg/L,the residue cyanide lower the standard value(0.05 mg/L) and when active chlorine>6.0 mg/L,residue cyanide... |
| Keywords: | cyanide compounds sulfide hydrazine hydrate pre-chlorination emergent water-treating technology |
