用水射器投氨技术的改进

IMPROVEMENT ON JET-AMMONINATION

我国自来水传统采用氯消毒法。近年来不少水厂开始使用氯氨消毒,效果优于前者。但投氨器出水口常被 CaCO_3和 MgCO_3沉积堵塞,影响正常消毒效果。佛山市自来水公司利用加氯水射器余压和加氯后出水呈酸性的特点,采用同一个水射器同时加氯加氨的方法,克服了上述堵塞现象的发生。现已运行四年,消毒效果一直稳定。

Recent years the chlor-amine disinfection process has been accepted in some waterworks in the country to replace the traditional chlorization with better effect as a result. However the normal operation of chlor-amine process always defeated because the outlets of the amine-dosing apparatus was blocked up by CaCO_3 and MgCO_3deposits.In virtue of the surplus head of chior-jet and the acid properties of chlorinated water,a simultaneous dosing of both chlorine and amine by one jet operation had been developed in Fushan Water Supply Company, Guangdong province to overcome the deposit problems.Four years performance with satisfied disinfection stated that this operation was successful.
