氯化磷酸三钠消毒不同水体应用试验研究

APPLICATION STUDY ON DISINFECTION BY CHLORINATED TRISODIUM PHOSPHATE IN DIFFERENT TYPE WATER

本文报告了氯化磷酸三销对医院污水、游泳池水、浅井水、河水的消毒试验方法和结果。结果表明：医院污水消毒加入有效氯9mg／L的氯化磷酸三钠，作用1h后可达到GBJ48—83医院污水排放标准；游泳池水消毒加入有效氯0．8mg／L作用1h后可达到游泳池水卫生标准；浅井水消毒加入有效氯0．8mg／L作用30min可达到饮用水有关卫生标准；河水消毒加放有效氯1．25mg／L作用1h，水质有很大改善，生物指标接近饮用水卫生标准。

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.
