In recent years, marine oil pollution resulting from exploitation spills and accidents during oil transportation and use has affected the marine ecosystem safety, and oil polluted sea water remediation becomes a global problem. Rice hull possesses a good property of adsorption pollutants and it can be easily obtained from the abundant produce of rice all around the world. This experiment used carbonized rice hull (CRH) as adsorbent, aiming to purify oil polluted sea water and explore optimal adsorption条件和影响。初始油浓度为1.35 mg/L，CRH剂量分别为0、6.67、13.33、20、26.67、33.33 g/L，进行六组实验。在理想投加量13.33 g/L下，油分去除率达70%，最低油分浓度为0.39 mg/L。在吸附时间0 h、1 h、2 h、3 h、4 h、5 h和相同CRH剂量13.33 mg/L下进行了另外六组实验。吸附3小时后，COD（35.5％）和油（71％）的去除率达到理想水平，最高COD去除率达到47.5％。
