According to the properties of hydrograph, constructing a arsenic-containing slag yard adjust measures to local conditions. Add solid arsenic and improved additive to slag yard can prevent arsenic-containing waste residue pollution on soil efficiently. 根据水文、地质的特点,因地制宜科学建含砷渣场,在渣场投加固砷和改性添加剂,可有效治理含砷废渣对土壤的污染。
In1994, Montgomery County, Alabama imposed a ban on the disposal of yard trimmings, which accounted for18 percent of the solid waste heading to a landfill. 在1994年,美国亚拉巴马州的蒙哥马利郡颁布了一项禁令,有关于处理庭院修剪下的草,那些草占垃圾填埋地固体垃圾的18%。
At present, the utilization of phosphogypsum rate less than 10 %, and most of them stacking in open-air yard, which not only occupy land resources, environmental pollution, but also caused the waste of resources. 目前我国磷石膏利用率不足10%,大量的磷石膏被堆放于露天堆场,不仅占用土地资源,造成环境污染,也造成资源浪费。
