工业废水处理现状

Current Situation of Industrial Wastewater Treatment

快速的城市化和工业化与水的消耗和废水的产生有着密不可分的联系。从工业废水中回收资源已被证明是一种极好的二次原材料来源,即能够提供经济和财政利益、清洁和可持续的弹性环境,并实现可持续发展目标。处理工业废水以获得可重复利用的资源已成为一项繁琐任务。大多数现有方法是常规的,不能为工业提供经济效益,并且具有某些缺点。然而,未经处理的工业废水被排入明渠、湖泊和河流,会造成环境污染和严重的健康危害。本文介绍了与废水处理相关的当前趋势、机遇、瓶颈和最佳实践,以及现有技术的进步范围。随着资源的有效回收,废水可以在增值材料、能源和产品回收的开发中得到理想的探索。

Rapid urbanization and industrialization are inextricably linked to water consumption and wastewater generation.Extracting resources from industrial wastewater has proven to be an excellent source of secondary raw materials,i.e.able to provide economic and financial benefits,a clean and sustainable resilient environment,and the achievement of sustainable development goals.Treating industrial wastewater for reusable resources has become a cumbersome task.Most of the existing methods are conventional,do not provide economic benefits to industry,and have certain drawbacks.However,untreated industrial wastewater is discharged into open channels,lakes and rivers,causing environmental pollution and serious health hazards.The current trends,opportunities,bottlenecks,and best practices related to wastewater treatment,as well as the scope of advancements in existing technologies,were described.With the efficient recycling of resources,wastewater could be ideally explored in the development of value-added materials,energy,and product recovery.
