转自:贵州日报 本报讯(记者 杨媛媛)2月8日,安顺市普定经开区贵州智慧快刻环保科技有限公司生产现场,脱硫石 膏经破碎、烘干、煅烧、搅拌等工序后,被加工成细腻均匀的喷涂石膏产品,随即发往贵阳、重庆等 地。 公司负责人聂盛介绍,燃煤电厂在发电过程中,会通过脱硫工艺减少二氧化硫排放,由此产生大量脱硫 石膏。同时,燃煤燃烧后还会产生粉煤灰。如何高效、安全地处置这些固体废物,一度是电厂面临的现 实难题。 沿着园区道路前行,几百米外的贵州胜焱新型建材有限公司生产车间内,一块块刚下线的加气砖整齐排 列,等待养护完成后运往施工现场。 公司董事长姚富胜介绍,这些产品以粉煤灰为主要原料,混合电厂冷却水制浆,再通过高温蒸汽养护成 型,重量仅为传统黏土砖的三分之一,具备良好的隔音、隔热性能,市场需求稳定。 在普定,这样"变废为材"的企业已形成集群。目前,普定经开区共有大宗固废综合利用企业11家,每年 可消纳脱硫石膏103万吨、粉煤灰37万吨。 普定周边有国能安顺电厂、盘江(普定)电厂两座大型电厂,固体废物产出量大、种类集中。正是看中 这点,该公司选择在普定落地,依托园区完善的配套条件,很快形成规模化生产能力,目前每小时可处 理脱硫 ...
