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 1.0 NTU, 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.
