摘要

对连续流电凝法处理医院污水的技术可行性进行了评价。根据化学需氧量(COD)、生化需氧量(BOD)、总悬浮物(TSS)、萘普生、苯酚和磷酸盐等参数对废水进行理化表征。采用Box-Behnken实验设计和统计响应面法(RSM)评价独立参数(pH、电位、停留时间)的单一效应和综合效应，并考虑COD响应变量，优化电凝工艺条件。最佳电絮凝条件为pH(7.92)、电势(40 V)、停留时间(15 min)， COD去除率为75.5%、BOD去除率为59.2%、酚类去除率为80.7%、磷酸盐去除率为85.3%、TSS去除率为75.6%、萘普生去除率为55.7%。电凝法是一种高效、技术可行的医院污水处理方法。

Continuous Flow Electrocoagulation as a Hospital Wastewater Treatment

The technical feasibility of the continuous flow electrocoagulation process for hospital wastewater treatment was evaluated. The wastewater physicochemical characterization was performed according to the chemical oxygen demand ( COD) , biochemical oxygen demand (BOD), total suspended solids (TSS), naproxen, phenol and phosphates parameters. An experimental Box-Behnken design and statistical response surface methodology (RSM) were used to evaluate the simple and combined effects of the independent parameters (pH, potential, retention time), and to optimize electrocoagulation process conditions, considering the COD response variable. The removal percentage was: COD (75.5%), BOD (59.2%) phenols (80.7%), phosphates (85.3%), TSS (75.6%) and naproxen (55.7%), under optimal electrocoagulation conditions at pH (7.92), potential (40 V) and retention time (15 min). The electrocoagulation process proved to be an efficient and technically viable alternative for hospital wastewater treatment.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
