饮用水安全保障关键技术集成及工程示范

以北江水为原水，通过中试试验分别考察了以强化混凝、两相催化氧化助凝、活性炭吸附、膜分离和紫外消毒为核心的多种饮用水安全保障关键技术。结果表明以强化混凝为核心的工艺在重金属去除方面有优异的表现，两相催化氧化助凝技术在节能减排方面表现突出，超滤膜技术在浊度去除方面有优势，臭氧一生物活性炭工艺对有机物的去除效果较好，紫外消毒技术能有效减少消毒过程中有毒有害副产物的生成。

Integration of Key Technologies and Demonstration of Engineering Project for Drinking Water Safety and Security

Pilot study was performed to investigate several processes for the safety gnarantee key technology of drinking water from Bei River source water. The combined processes used enhanced coagulation, two phase catalytic oxidation of coagulant, activated car- bon （AC） adsorption, membrane separation, ultraviolet （UV） disinfection as the core unit respectively. Results show that the combined processes using enhanced coagulation as the core unit achieve better heavy metal removal, the process of two phase catalytic oxidation of coagulant performs better in energy conservation and emission reduction, ultrafiltration （UF） membrane technology performs better in turbidity removal, the ozonation-biological activated carbon （BAC） process performs better in removing organic matter, and UV dis- infection can effectively reduce the formation of toxic by-products in the disinfection process.
