【摘要】 从当前水体水质恶化,藻类、红虫控制的迫切性入手,重点介绍了紫外线给水预处理技术的试验研究和经济分析,结果表明,紫外预处理技术在灭藻效果上较预氯化好,能避免由氯化带来的消毒副产物问题,并在一定程度上有效控制红虫,且应用成本相对较低,是一种安全、经济、有效的给水预处理方法。更多还原

【Abstract】 The technology and economical analysis of ultraviolet water pretreatment are presented, the factors, which cause water quality deterioration in recent time like algae and red worms are most attended. The results show that UV pretreatment without disinfection by-products has better removal on algae than pre-chlorination and certain control of red worms. Also the expenses of UV are lower and it is believed this is a method of safety, economical and effective for raw water pretreatment.更多还原
