采用混凝-沸石-微滤联用工艺对景观海水进行深度处理,探讨该工艺对景观水体主要污染物的去除效果。结果表明,该组合工艺对景观海水净化效果明显,在连续运行条件下,出水的水质稳定,浊度、色度、总磷、氨氮、CODMn浓度分别低于1.0 NTU、25(°)、0.1 mg/L、0.5 mg/L和4 mg/L,未检出粪大肠菌群,处理后的水质达到《地球水环境质量标准》GB 3838-2002中Ⅳ类水质标准,能够满足景观用水的要求。该试验结果为景观海水强化处理技术提供了理论依据。
Abstract：A combined process of coagulation-zeolite adsorption-microfiltration was carried out for advanced treatment of landscape seawater,in order to discuss the removal efficiency of the process on the main pollutants in landscape water. The experimental results showed that the purification effect of the combined process on landscape seawater was obvious. Under the condition of continuous operation,the turbidity,chromaticity,total phosphorus,ammonia nitrogen,COD concentration were less than 1. 0NTU,25( °),0. 1 mg / L,0. 5 mg / L,4 mg / L respectively with no fecal coliform bacteria detection,and the effluent quality was stable,which has reached the Ⅳ standard of surface water environment quality standard GB 3838-2002,and meets the requirements of landscape water. The research can provide the theoretic basis and technical support for strengthening treatment of the landscape seawater.
