1500条道路尘土“以克论净”
2017-08-22 04:16:35 中国青年网
市城管委环境卫生管理处副处长谢广庆说,从今年3月开始,全市每月检测范围扩大到90条,除城六区每区每月5条不变外,郊区和市直作业单位检测数量均实现翻倍,分别为每区每月4条和每月20条,检测得出的分值在区环境作业月考评体系中占到20%。“目前是对一级保洁道路进行检测,明年计划扩大到二级保洁道路。”同时,市城管委官方网站上也专门设立了“尘土残存量检测”栏目,定期向社会公布检测结果。
重点道路机械冲洗2次以上
据了解,道路尘土量每平方米低于30克后,人的肉眼就很难辨别,只有通过精密测量才能查看。环科所曾经做过测试,对实行洗地作业和未洗地作业的道路路面进行测量,尘土残存量数值差距达到一倍以上。为有效提升城市道路整洁、降低尘土飞扬,从2014年开始,全市环卫系统开始大力引进新工艺、新设备,在重要道路和区域均引入新型多功能清扫设备推广洗地作业。
“我们给一级道路的尘土残存量定的标准是每平方米10克为满分,高于70克就算零分。”市城管委相关负责人说,通过几年来的不断努力,各区、各单位的道路作业水平得到了有效提高,数据显示,从2012年到去年,全年道路尘土残存量检测数据从每平方米19克下降至14.8克,今年1月至7月全市检测数值为每平方米13.5克,比去年同期下降5%。“应该说,道路尘土残存量精准检测解决了环卫作业量化考核的难题。”
为了进一步提升环境质量,今年3月起,本市道路作业标准再次提升,在1500条一级保洁道路每日清洗一次的同时,1900余条二级保洁道路改“隔日一洗”为“每日一洗”,清洗面积超过8500万平方米。进入春夏季节,全市开展夜间冲刷、清扫和白天保洁作业,强化机械洗地作业,全市一、二级清扫保洁道路达到每日冲洗2次以上。此外,新标准还首次对冬季洗地作业进行了硬性规定,日均气温高于3摄氏度时,一、二级道路均要进行路面清洗。
