制药,个人护理产品(PPCP),和内分泌干扰化合物(EDC)的使用最近持续增加,导致废水中的排放和积累增加。传统的水处理和消毒方法在有效解决这种微污染物问题方面有些受限。超声(美国),作为高级氧化过程,是基于超声波照射的原理,将水暴露在高频波中,诱导H2O热分解,同时使用产生的自由基氧化和分解溶解的污染物。这篇综述评估了过去五年对基于美国的有效降解水中EDC和PPCP的技术的研究,并评估了可能影响去除率的各种因素:溶液pH值,水的温度,背景常见离子的存在,天然有机物,作为启动子和清除剂的物种,和美国条件的变化(例如,频率,功率密度,和反应类型)。这篇综述还讨论了各种类型的碳/非碳催化剂,O3和紫外工艺结合US工艺可进一步提高EDC和PPCP的降解效率。此外,考虑了许多类型的EDC和PPCPs以及这些有机污染物的最新研究趋势。
Pharmaceuticals, personal care products (PPCPs), and endocrine-disrupting compounds (EDCs) have seen a recent sustained increase in usage, leading to increasing discharge and accumulation in wastewater. Conventional water treatment and disinfection processes are somewhat limited in effectively addressing this micropollutant issue. Ultrasonication (US), which serves as an advanced oxidation process, is based on the principle of ultrasound irradiation, exposing water to high-frequency waves, inducing thermal decomposition of H2O while using the produced radicals to oxidize and break down dissolved contaminants. This
review evaluates research over the past five years on US-based technologies for the effective degradation of EDCs and PPCPs in water and assesses various factors that can influence the removal rate: solution pH, temperature of water, presence of background common ions, natural organic matter, species that serve as promoters and scavengers, and variations in US conditions (e.g., frequency, power density, and reaction type). This
review also discusses various types of carbon/non-carbon catalysts, O3 and ultraviolet processes that can further enhance the degradation efficiency of EDCs and PPCPs in combination with US processes. Furthermore, numerous types of EDCs and PPCPs and recent research trends for these organic contaminants are considered.
