十年换新颜:华煤的绿色嬗变

2017-08-16 06:42:24   中国青年网

偌大的矿区里,不管是储煤场、洗煤车间,还是生活办公区域,都见不到灰尘飞扬,绿荫却随处可见。华亭煤业集团是甘肃省最大的煤炭企业,记者日前来到该集团的华亭矿区,不禁眼前一亮。

10多年前的华亭矿区,无论矿区还是居住区域都时常弥漫着煤尘。近年来,华亭煤业集团坚持走绿色发展的路子,将生态文明建设作为企业可持续发展的动力和源泉,推动生态华煤建设,竭力保护矿区的碧水蓝天。

“节能环保、绿色发展,华亭煤矿的主色调由黑向绿转变,这是国家生态文明建设的基本要求,更是我们企业自身可持续发展的动力和源泉,抓节能环保,就是抓煤炭企业的未来。”华亭煤业集团党委书记、董事长马宝彦说。

在华亭矿区陈家沟煤矿污水处理站,职工刘小华正在向COD检测仪中添加检测水质所用的药剂。

为保证水质监测的及时性和精确性,近年来,华亭煤业集团给各生产矿井购入了技术先进、监测精准的COD在线监测仪。“经过一年运行,我们监测的COD数据一直在每升10毫克~20毫克之间,数据和平凉市环保局的监测数据一致,符合环保达标要求。”刘小华告诉记者。

为了让矿区污水变清流、实现水质达标,华亭煤业集团足足花了10年时间。

自2008年以来,华亭煤业集团累计投资约5亿元,集中开展生产污水治理和生活污水治理工作。10年来,新建和改扩建工业污水处理站11座,设计处理能力每天2.94万立方米;生活污水处理站11座,设计处理能力每天5444立方米。

在华亭矿区,污水经过处理后重复使用,既变废为宝,也减少了环境污染。2013年以来,华亭煤业集团累计处理工业污水2393万立方米,污水经处理后用于井下生产、洗煤及矿区绿化,重复利用率达到75%以上。如今,流经矿区的河流清澈见底,不复多年前黑水河的模样。

此外,华亭煤业集团对全产业链加大技术投入,对锅炉烟气脱硫、煤制甲醇公司污水处理等系统进行了技术改造,实现了达标排放。去年11月,陈家沟煤矿锅炉烟气脱硫除尘改造工程顺利竣工,锅炉投入运行,意味着这台锅炉的二氧化硫、烟尘实现了达标排放。

在陈家沟煤矿,记者在锅炉房看到,脱硫塔监测工尤明星正在目不转睛地盯着监测屏幕。除了监测数据之外,尤明星还要定时巡查,和现场操作人员沟通协调,确保脱硫工作平稳运行。“脱硫是降低煤炭排放污染的关键,抓住这个关键,才能确保矿区的一片蓝天。”尤明星说。
