Abstract

sludge (Makisha and Yunchina 2017, Rossini and Bernardes 2006, Sanito et al. 2022). The main treatment and disposal methods include pyrometallurgical (Yang et al. 2022, Kwon and Sohn 2020, Barakat 2003), hydrometallurgical, and bio-hydrometallurgical processes (Dvořák and Jandova 2005, Jha et al. 2001, Rudnik 2019). The stabilization of toxic metals in post-galvanic wastes takes place using various techniques, one of which is solidification, i.e., immobilization in a solid matrix by means of lime hydrate or cement (bituminating in solidified melt (Bednarik et al. 2005), cementation (Luz et al. 2009, Stepanov et al. 2016, ), vitrification (Irisawa et al. 2021, Krstiš et al. 2018, Sanito et al. 2022)). Combined methods also deserve attention because they allow the problem of galvanic sludge to be solved and the search for an optimal process for recovering elements from this sludge with the highest possible purity (Krishnan et al. 2021).

利用土工聚合物从电镀污泥中去除锌（II）离子的研究

污泥（Makisha 和 Yunchina，2017 年；Rossini 和 Bernardes，2006 年；Sanito 等，2022 年）。主要的处理和处置方法包括火法冶金（Yang 等人，2022 年；Kwon 和 Sohn，2020 年；Barakat，2003 年）、湿法冶金和生物湿法冶金工艺（Dvořák 和 Jandova，2005 年；Jha 等人，2001 年；Rudnik，2019 年）。电镀后废物中有毒金属的稳定化采用多种技术，其中一种是固化技术，即通过石灰水合物或水泥（在固化熔体中沥青化（Bednarik 等人，2005 年）、水泥化（Luz 等人，2009 年；Stepanov 等人，2016 年）、玻璃化（Irisawa 等人，2021 年；Krstiš 等人，2018 年；Sanito 等人，2022 年））将其固定在固体基质中。组合方法也值得关注，因为它们可以解决电镀污泥问题，并寻找最佳工艺，以尽可能高的纯度从污泥中回收元素（Krishnan 等人，2021 年）。

期刊介绍： Archives of Environmental Protection is the oldest Polish scientific journal of international scope that publishes articles on engineering and environmental protection. The quarterly has been published by the Institute of Environmental Engineering, Polish Academy of Sciences since 1975. The journal has served as a forum for the exchange of views and ideas among scientists. It has become part of scientific life in Poland and abroad. The quarterly publishes the results of research and scientific inquiries by best specialists hereby becoming an important pillar of science. The journal facilitates better understanding of environmental risks to humans and ecosystems and it also shows the methods for their analysis as well as trends in the search of effective solutions to minimize these risks.
