摘要
针近年来,我国产生大量报废CRT电视机,其中含铅废玻璃的处置缺乏问题没有被有效地解决。采用斯坦福估算模型,计算出近年我国CRT电视机的表观消费量后,结合技术进步与政策支持的加速因素,估算2013年理论报废量达3500万台,并预测2015~2020年均报废量约为1000万台。通过调研9~32寸CRT电视机的玻璃重量与结构,典型29寸CRT电视机含铅量约2公斤。估算2013年报废CRT中铅含量约677吨,今后至2020年年均产生量为277吨,社会累积量从2013年的33万吨上升至2020年的43万吨。得出废铅的环境小于显著高于其资源效益,电视机使用寿命与回收率是影响社会累积量的关键因素,并提出相应的政裳建议。
In recent years, a large amount of obsolete CRT TVS, which leaded glass waste disposal problem were not treated properly. In this paper, Stanford estimation model is used, with the calculated apparent consumption of CRT television in recent years, combined with the acceleration of technological progress and policy factors, it's estimated in 2013, the amount of obsolete CRT TV will reach to 35 million, and it's forecasted that the average annual amount is 10 million units during 2015-2020. Through researching the weight and structure of 9-32 inch CRT TV glass, it's found that lead content in a typical 29-inch CRT TV is about 2 kilograms, and it's estimated lead content is about 60,000 tons in 2013, and this average number will be 20,000 tons until 2020. The society cumulative amount is 330,000 tons from 2013 to 43 million tons in 2020. It's found that environment lifecycle and recovery rate are the key factors affect the are proposed.
