Abstract

Conventional wastewater treatment technologies have been extensively studied for degrading organic matter, suspended solids, nutrient removal, and lowering microbial loads. They produce acceptable-quality effluent, but researchers have reported several limitations. Recently, advanced wastewater treatment technologies have preceded as an alternative to the degradation of recalcitrant wastes such as persistent organic compounds (POPs), pharmaceutically active compounds (PhACs), contaminants of emerging concern (CECs), and heavy metals (H.M). They can be physical, chemical, biological, or integration between one or more technologies. This is to meet the requirements for reuse for different purposes, minimize or prevent the negative impacts on the environment, and create new untraditional water resources to solve the water shortage problem. This article is a collected review of advanced wastewater treatment technologies. Also, the applications of these technologies with special concern for partially/hardly degradable pollutants from wastewater are indicated. They are eco-friendly, cost-effective, low-energy systems with a small footprint. Their selection depends on the characterization of wastewater, biodegradability, available footprint, quality of treated effluent required, cost, availability of funds, and personal skills.
去除废水中污染物的先进处理技术
传统的废水处理技术在降解有机物、悬浮固体、去除营养物和降低微生物负荷方面已得到广泛研究。这些技术能产生可接受质量的污水,但研究人员也发现了一些局限性。最近,先进的废水处理技术已成为降解持久性有机化合物 (POP)、药物活性化合物 (PHAC)、新出现的污染物 (CEC) 和重金属 (H.M) 等难降解废物的替代方法。它们可以是物理的、化学的、生物的,也可以是一种或多种技术的集成。这样做是为了满足不同用途的回用要求,最大限度地减少或防止对环境的负面影响,并创造新的非传统水资源来解决水资源短缺问题。本文收集整理了先进的废水处理技术。此外,还介绍了这些技术的应用,特别关注废水中的部分/难降解污染物。这些技术都是环保、经济、低能耗、占地面积小的系统。对这些技术的选择取决于废水的特性、生物降解性、可利用的占地面积、所需处理废水的质量、成本、可用资金和个人技能。
