In this study, the fate and removal of 15 pharmaceuticals (including stimulants, non-steroidal anti-inflammatory drugs, antibiotics, etc.) in unit processes of a sewage treatment plant (STP) were investigated. Mass loads of pharmaceuticals were 2,598 g/d in the influent, 2,745 g/d in the primary effluent, 143 g/d in the secondary effluent, and 134 g/d in the effluent. The mass loads were reduced by 95% in the biological treatment process, but total phosphorous treatment did not show a significant effect on the removal of most pharmaceuticals. Also, mass balance analysis was performed to evaluate removal characteristics of pharmaceuticals in the biological treatment process. Acetaminophen, caffeine, acetylsalicylic acid, cefradine, and naproxen were efficiently removed in the biological treatment process mainly due to biodegradation. Removal efficiencies of gemfibrozil, ofloxacin, and ciprofloxacin were not high, but their removal was related to sorption onto sludge. This study provides useful information on understanding removal characteristics of pharmaceuticals in unit processes in the STP.

해수담수화의기술방식은 2000년대이후증발식담수방법 에서 분리막 방식인 역삼투 방식으로 전환되어 많은 연구가 진행중에있다 (GWI 2010 ; Desalination Markets 2010). 또 한, 수처리 기술은 물부족 지역에서 활용해야하기 때문에 전 세계이동식수처리시장은점차확대되고있다. 이동식수처 리시장은 2016년 9억 달러수준에서 2019년까지매년 11.2% 의 성장이가능할것이며, 이는아시아지역에서주도할것으 로 예측하고 있다 (GMR 2016). 본 연구에서는 미국 플로리다 주, 호주 시드니의 정수 혼 합 시스템과 해수담수화 공정에서의 워터 블랜딩 기술에 관 한 연구에 관한 사례(Xiao, 2004; Taylor et al., 2005)를 바탕 으로 다중수원을 활용한 연구를 수행하였다. 다중수원을 활 용한수처리공정을진행하고, 이의전력소모량을줄이기위 해 컨트롤밸브를 활용하였고, 워터블랜딩 공정을 기반으로 유입수를 블랜딩하는 pre 블랜딩, 공정내 블랜딩을 수행하는 inter 블랜딩, 처리수를 블랜딩하는 post 블랜딩을 활용하고 결합하는 연구를 수행하였다.
海水淡化的技术方式自2000年以后由蒸发式淡水方法转变为分离膜方式的逆渗透方式，正在进行大量研究(GWI 2010;desalination markets 2010)。另外，韩、水处理技术必须在缺水地区使用，因此全世界移动饮用水处理市场正在逐渐扩大。移动饮用水处理市场预计将从2016年的9亿美元到2019年每年增长11.2%，这将在亚洲地区主导(GMR 2016)。本研究以美国佛罗里达州、澳大利亚悉尼的净水混合系统和海水淡化工程中的水混合技术研究为例(Xiao, 2004;Taylor et al.(2005))的研究。多重弓可以利用水源进行处理工程,减少电量也提出三点异议,利用控制阀门,水流入“landing”工程基础数博客landing的pre布拉landing,公正我博客进行landing的inter布拉布拉landing landing,处理可能的post博客利用landing,完成相结合的研究。
