According to the idea of sustainable development, humanity should make every effort to care for the natural environment along with economic development. Decreasing water resources in the world makes it necessary to take action to reduce the consumption of this resource. This article presents the results of research conducted to improve the use of recyclable materials in line with the circular economy model. The research focused on the development of a technological solution for the recovery of raw materials from galvanic wastewater. The concept of a galvanic wastewater treatment system presented in the article includes wastewater pre-treatment in the ultrafiltration (UF) process and water recovery in the reverse osmosis (RO) process. In addition, the purpose of the work was to manage post-filtration waste (RO retentate) containing high concentrations of zinc in the process of galvanizing metal details. The obtained results indicate that it is possible to reduce the amount of sewage from the galvanizing industry by reusing the recovered water as technical water in the process line. The carried-out model tests of galvanizing confirmed the possibility of using RO retentate for the production of metal parts. The achieved results are a proposal to solve the problem of reducing the impact of galvanic wastewater on the environment and to improve the profitability of existing galvanizing technologies by reducing the consumption of water and raw materials.
根据可持续发展理念,人类应在经济发展的同时全力关爱自然环境。全球水资源的减少使得采取行动减少这种资源的消耗成为必要。本文介绍了为按照循环经济模式提高可回收材料利用率而开展的研究结果。该研究聚焦于开发一种从电镀废水中回收原材料的技术解决方案。本文提出的电镀废水处理系统概念包括在超滤(UF)过程中进行废水预处理以及在反渗透(RO)过程中进行水回收。此外,这项工作的目的是在金属零件镀锌过程中管理含有高浓度锌的过滤后废物(RO浓缩液)。所获结果表明,通过将回收水作为工艺线中的技术用水进行回用,有可能减少镀锌行业的污水量。所进行的镀锌模型试验证实了使用RO浓缩液生产金属零件的可能性。取得的成果是一项建议,旨在解决减少电镀废水对环境的影响这一问题,并通过减少水和原材料的消耗来提高现有镀锌技术的盈利能力。
