Abstract
Effect and experimental method on disinfection by chlorinated trisodium phosphate in hospital sewage. water in swimming pool, water in shallow well and river water were studied in laboratory. The results showed that disinfection effect of sewage in hospital with 9mg/L available chlorine in chlorinated trisodium phosphate for 1h could come up to draw off standards of GBJ48-83 on sewage in hospital; disinfecton effect of water in swimming pool with 0. 8mg/L available chlorine for 1h could come up to sanitation standards of water in swimming pool; disinfection effect of water in shallow well with 0. 8mg/L available chlorine for 30min could come up to sanitation standards of drinking water; disinfection results of river water with 1. 25mg/L available chlorine for 1h could make microbiological index to be close sanitation standards of drinking water, and improve water quality greatly.
