铜冶炼车间重点防渗区的防渗工艺探讨

Discussion on anti-seepage technology for key impervious area of copper smelting workshop

铜冶炼过程中经常产生或使用酸、碱等具有腐蚀性或毒性的危险化学品,我国早期建设的铜冶炼车间普遍只考虑防腐蚀,但现在新建或改、扩建的铜冶炼车间一般都要求防渗。文章从防渗标准、防渗材料、防渗结构以及检漏设施等方面探讨了铜冶炼车间重点防渗区的防渗要求及工艺,并提出将HDPE膜作为主要防渗材料的4种防渗结构层以及采用HDPE管设置检漏设施,可为同类项目防渗处理提供借鉴和参考。

In the process of copper smelting,the corrosive or toxic dangerous chemicals such as acid,alkali will be produced or used.In the early construction of copper smelting workshops in China,anti-corrosion measures are generally considered,while anti-seepage treatment is basically required for the new constructions,renovation projects and expansion peojects of copper smelting workshops.This paper discusses on the anti-seepage requirements and technologies for the key impervious area of copper smelting workshop from the anti-seepage standard,anti-seepage materials,anti-seepage structure and leakage detection facilities,and puts forward four kinds of anti-seepage structure layers with HDPE film as the main anti-seepage material and leakage detection facilities with HDPE pipe,aiming to provide a reference for the anti-seepage treatment of similar projects.
