摘要
西门子法多晶硅生产时产生大量的副产物SiCl_4等氯硅烷为有毒物质,如不能有效地回收利用将造成资源的极大浪费和严重的环境污染。国内某大型多晶硅生产企业通过采取有效的综合利用措施,将氯硅烷副产物最大限度地转化为生产原料及产品,使多晶硅生产形成了完整的物料闭路循环系统,对促进我国多晶硅企业可持续发展,实现资源的再利用起到了示范作用,符合循环经济的原则。
A large amount of by-product, e. g poisonous chlorsilane of SiCl4 and etc. have been produced during polysilicon production by Simens Method. These poisonous substances may cause great resource-wasting and serious environment pollution if they can not be recycled effectively. Through taking effective measures of comprehensive utilization, large polysilicon-production enterprises in China have most unlimitedly translated polysilicon by-product into raw material and products, makes polysilicon production form complete closed-loop recycling system, serves as a model for promoting sustainable development of polysilicon enterprises in China, realizing recycle of resource. It is in conformity with the principle of recycle economy.
