如何破解工业固废处置难题?
Zhong Guo Huan Jing Bao· 2025-08-27 02:11
当前在一些地方,工业固体废物综合利用率提升缓慢,加之消纳场地容量有限,导致出现工业固废产生 和消纳不均衡的问题。存量工业固废通常采用临时堆场填埋,部分堆场标准不高、管理粗放,生态环境 风险突出,亟须破解存量工业固废综合利用和无害化处置难题,规范堆场标准化建设。 工业固废处置面临的问题 综合利用率低,临时贮存成为主要处置方式。工业固废综合利用手段缺乏创新,过分依赖制作成建筑材 料和无害化处置填埋消纳。但由于多种原因,大量工业固废既未被综合利用也未被处置。比如某热电厂 在运行过程中会产生大量脱硫石膏和粉煤灰,对其的综合利用和无害化处置手段主要是送至建筑行业企 业作为原辅材料。但由于建筑行业不景气,脱硫石膏和粉煤灰只能临时贮存,综合利用率不足21%。过 剩的工业固废长期得不到处置,临时堆场变成长期贮存点,带来较大的生态环境风险。 堆场建设不规范,带来生态环境污染风险。工业固废贮存受土地性质、建设成本、场地使用批复等多方 面因素限制,一些地方在建设临时堆场时缺乏长远考虑,建设标准不高。由于综合利用率低,临时堆场 变成永久贮存点,部分企业将其交由第三方公司监管,但因资金等制约,存在长期运维不到位的问题。 比如因利用率下 ...
