聚丙烯酰胺絮凝剂处理黄河水系高浊度水已有十余年历史,经过较长时期的试验和生产运行,证实有较大的经济技术效果。但有关使用聚丙烯酼胺絮凝剂处理高浊度水时的水质卫生标准,产品质量控制要求和在给排水其它领域及食品卫生等行业中,使用情况却较少研究和报道;尤其是水质卫生标准和产品质量要求,自开始使用以来一直有较大的分歧意见。为了全面、系统地掌握聚丙烯酰胺的毒理性质,确定水质卫生指标中聚丙烯酰胺最大容许量,兰州地区曾组织了
Polyacrylamide flocculants have been used for more than ten years in the treatment of high turbidity water in the Yellow River water system. After a long period of trials and production operations, it has proved that there are great economic and technological effects. However, regarding the use of polypropylene indoleamine flocculant in the treatment of high turbidity water quality standards, product quality control requirements, and in other areas of water supply and drainage and food hygiene, the use of the situation is less studied and reported; especially water quality hygiene Standards and product quality requirements have been widely disagreed since the beginning of use. In order to fully and systematically grasp the toxicological properties of polyacrylamide and determine the maximum allowable amount of polyacrylamide in the water quality hygiene index, Lanzhou has organized
