摘要
存量污泥是我国目前环境治理的一大难点,其对周边大气、土壤及地下水造成了严重威胁,尤其存量工业污泥危害更为严重。以辛集某制革污泥堆场为例,探索了一套“垂直阻隔+真空预压/浅层固化+原位固化稳定化+水平阻隔”的工程设计方案,经工程验证实施效果良好,可用于存量污泥场地的原位修复。
Stock sludge is a major difficulty in China's current environmental control,which poses a serious threat to the surrounding atmosphere,soil and ground water,especially the stock industrial sludge.Taking a tannery sludge dump in Xinji as an example,this paper explores a set of engineering design scheme of“vertical blocking+vacuum preloading/shallow solidification+in-situ solidification and stabilization+horizontal blocking”.The project has proved that the implementation effect is good and can be used for the in-situ restoration of the sludge storage site.
