道路除尘、抑菌喷洒用水的研究

Study on Spraying Water for Road Dust Removal and Bacteriostasis

目的:研究一种含有2.5%的氯化钙的作为道路除尘、抑菌喷洒用水,并对其可行性进行评价。方法:采用路面喷洒实验和路边植被喷洒实验验证其对路面保湿和吸纳尘埃效果。采用悬液定量法验证其抑菌效果,采用金属腐蚀性实验验证其对洒水车罐体的安全性。结果:2.5%氯化钙溶液对路面具有明显的保湿作用和吸纳近地面尘埃的效果,对路旁绿化带植物正常生长无不良影响,对金黄色葡萄球菌作用15 h时,有较强抑菌效果,对洒水车罐体基本无腐蚀。结论:所研究的2.5%的氯化钙溶液有吸纳尘埃效果,有抑菌作用并且对洒水车罐体基本无腐蚀,用于道路除尘、抑菌喷洒用水是可行的。

Objective:To study the water containing 2.5%calcium chloride used as a spraying water for road dust removal and bacteriostasis,and evaluate its safety.Methods:Using spraying experiments on road surfance and green plants beside the road to verify its moisturizing effect on the road and the dust absorption effect near the ground.The method of Suspension quantitative was used to verify the antibacterial effect,and metal corrosion test was used to verify the safety of the sprinkler tank.Results:The solution of 2.5%calcium chloride had obvious moisturizing effect on the road and dust absorbtion near the ground,no adverse effect on the normal growth of plants beside the road,showing strong bacteriostatic effect when it was applied to Staphylococcus aureus for 15h,no corrosion on the tank of sprinklers.Conclusion:The 2.5%calcium chloride solution has the effect of dust absorption,antibacterial effect and no corrosion on the tank of sprinkler,which is feasible for road dust removal and antibacterial spraying water.
