摘要
U_1是我们研制成功的一种新型杀菌灭藻剂。其有效成分是二硫氰基甲烷和二氯异氰尿酸钠.本文报导该药剂对比目前国内工业循环冷却水常用的5种杀生剂对水土中常见的细菌、霉菌以及工业循环冷却水中主要危害菌、藻的抑杀效果。
U_1 is a novel biocid.Its active ingredient is methyl bisthiocyanate and sodium dichloroisocyanurate.The effect of U_1 was compared with the chemicals commonly used in recirculating cooling water system in factories in China at the present time The results revealed that U_1 is better Than any one of them. The data indicate That U_1 has broad spectrum,strong microbiocidal power,long activity and fast rate of killing.When The water was treated with U_1 at a concentration of 10 ppm,over 99% of the undesirable microorganisms such as slime-forming bacteria,iron bacteria and sulfate -reducing bacteria were killed These organisms are responsible for corrosion and other harmful effdcts in recirculatng cooling water systems.Three days after the test algae had been treated with U_1 at a concentration of 50 ppm,the algae were bleached due to the destruction of their chloropylls and eventually the algae were killed.
