Abstract:

Based upon the water quality characteristics in Zhengzhou and the water quality and scaling analysis of the central air-conditioning circulating water system of Hualian Trade Center, Zhengzhou, a brand new lowphosphorus environment-friendly water treatment agent，HL-08 has been prepared. Its phosphorus(PO ₄ ^3-) content is less than 5%. The static and dynamic experiments as well as its application in central air-conditioning circulating water systems show that HL-08 has good effects on corrosion and scale inhibition. Meanwhile, the wastewater from the circulating water system contains less than 1.0 mg/L phosphorus，which meets the requirements of the discharge standard (GB 8978—1996).

Key words: central air-conditioner, environment-friendly water treatment agent, corrosion and scale inhibition

摘要：

根据郑州华联商贸城中央空调循环水系统的水质情况和结垢分析,结合郑州地区水质特点,制备了一种新型低磷环保型的水质处理剂HL-08,其磷含量≤5%(以PO43-计)。静态、旋转挂片、动态试验及在中央空调循环水系统中的实际应用结果表明,该处理剂缓蚀阻垢效果良好,循环水排污水中磷质量浓度<1.0 mg/L(以P计),符合国标(GB 8978—1996)的要求。
