本论文针对安徽省来安县CH村镇水厂出厂水进行水质提升研究。CH水厂水源来自当地小型水库，水质波动比较大；CH水厂采用强化常规处理工艺，其出水水质不能满足国家生活饮用水卫生标准【GB5749-2006】要求，主要超标项目是浊度、CODMn、Mn和嗅味等。本论文采用新型臭氧/陶瓷膜-活性炭组合工艺，研究了组合工艺出水水质和运行参数等。本论文还进一步研究了新型工艺处理排泥水的去除效果以及运行成本。本论文采用中试规模实验装置，处理量为10 m3/d，常规检测指标包括浊度、色度、CODMn、Mn、氨氮、亚硝酸盐氮和微生物等，非常规检测指标包括典型嗅味物质(2-MIB、DTMS和GSM)、药物与个人护理品(PPCPs)和内分泌干扰物(EDCs)等。本论文系统地研究了臭氧/陶瓷膜与活性炭组合工艺处理效果、运行参数和运行成本。臭氧/陶瓷膜与活性炭组合工艺能够显著改善常规工艺出水水质，相关水质指标达到国家饮用水标准。在臭氧投加量为3 mg/L，陶瓷膜通量为90 LMH条件下，组合工艺对浊度、色度、CODMn和Mn平均去除率分别为91.6%、96.7%、58.4%和76.0%。组合工艺还能够有效去除水中嗅味物质，对2-MIB 、DMTS和GSM的去除率达到100%。臭氧/陶瓷膜与活性炭组合工艺能够直接净化ST水厂原水，当臭氧投加量为3 mg/L，陶瓷膜通量为100 LMH时，其对浊度、色度、CODMn、氨氮、EDCs、PPCPs的去除率分别为99.8%、99%、72.9%、99%、92.8%和82.2%，组合工艺出水中未检测到大肠菌群，水质达到了国家饮用水卫生标准，而且大幅度提高了净化工艺集成水平。采用臭氧/陶瓷膜与活性炭组合工艺直接处理排泥水，结果表明，当臭氧投加量为3 mg/L，陶瓷膜通量为100 LMH时，其对浊度、色度、CODMn、氨氮、PPCPs、EDCs、DMTS和2-MIB的平均去除率分别为99%、100%、86.1%、72.3%、95.4%、78.3%、90.3%、100%，其出水能够达到国家饮用水标准，实现排泥水回收利用，提高水资源利用率。本论文研究表明，臭氧/陶瓷膜与活性炭组合工艺能够适应供水系统中不同类型水质净化要求，水质能够达到国家饮用水质标准，工艺集成度高，运行稳定，经济可行，为农村饮用水提供了新型高效处理工艺，这对于保障农村居民饮用水安全健康具有重要意义。

This paper focuses on the water quality improvement of CH village Waterworks in Lai'an county, Anhui Province. The water source of CH water plant comes from local small reservoirs, and the water quality fluctuates greatly. The process of CH water plant is enhanced conventional treatment process, and its effluent quality can not meet the national standard for drinking water (GB5749-2006). and its main exceeding standard items are turbidity, CODMn, Mn and odor, etc. In this paper, a new integrated process of ozone/ceramic membrane-activated carbon is used to study the effluent quality and operation parameters of the combined process. In addition, this integrated process is applied to treat the sludge water in the water plant and study the removal efficiency and operation cost of the new process. A pilot-scale experimental device with a treatment volume of 10 m3/d is used during the experiment. The turbidity, concentrations of chroma, CODMn, Mn, ammonia nitrogen, nitrite nitrogen, microorganisms and emerging organic contaminants are measured to assess the water quality. Three kinds of odorants (2-MIB, DTMS and GSM), 37 kinds of drugs and personal care products (PPCPs) and 7 kinds of endocrine disruptors (EDCs) are detected in the raw water and the treated effluents. The synergistic effects between the ozone/ceramic membrane unit and the activated carbon on the removal of pollutants have been analyzed. Moreover, the costs of this integrated process for the treatment of drinking water and sludge water are estimated to evaluate the economic feasibility.The combined process of ozone/ceramic membrane and activated carbon can significantly improve the effluent quality of conventional process, and the relevant water quality indexes can meet the national standard for drinking water. Under the condition of ozone dosage of 3 mg/L and ceramic membrane flux of 90 LMH, the average removal rate of turbidity, chroma, CODMn and Mn by the combined process are 94.8%, 99.9%, 56.7% and 77.3%, respectively. In particular, the combined process effectively removes the odorous substances and achieves a complete removal of 2-MIB, DMTS and GSM.Further, the combined process of ozone/ceramic membrane and activated carbon is used to directly treat raw source water of ST water plant. Under the condition of ozone dosage of 3 mg/L and ceramic membrane flux of 100 LMH, the removal rates of turbidity, chroma, CODMn, ammonia nitrogen, EDCs, and PPCPs are 99.8%, 99%, 72.9%, 99%, 92.8%, 92.8%, and 82.2%, respectively. No coliform was detected in the effluent of the combined process, and the water quality reached t the national standard for drinking water, and the integrated level of purification process was greatly improved.`The combined process of ozone/ceramic membrane and activated carbon is also applied for the reuse of sludge water, and the results show that when the ozone dosage is 3 mg/L and the flux of ceramic membrane is 100 LMH, the average removal rates for turbidity, chroma, CODMn, ammonia nitrogen, PPCPs, EDCs, DMTS and 2-MIB are 99%, 100%, 75.9%, 72.3%, 95.4%, 78.3%, 90.3%, and 100%, respectively. The effluent quality meets the national standard for drinking water, indicating the potable reuse of sludge water and enhanced utilization of water resources.It is evident to conclude from the findings above that the combined process of ozone/ceramic membrane and activated carbon can meet the requirements of different types of water purification in water supply system, and its effluent quality can meet the national standard for drinking water, and the process has high integration, stable operation and economic feasibility, which provides a new efficient treatment process for rural drinking water, which is of great significance to ensure the safety and health of rural drinking water.
