摘要: 为研究填料表面亲水改性对移动床生物膜反应器（MBBR）处理废水的影响，考察了氧化处理、酸处理和碱处理3种亲水改性方法所得不同聚丙烯K1型填料（水的液面接触角分别为41°、62°和75°，未处理填料为87°）对模拟船舶生活污水的处理效果。结果表明，亲水性越强，挂膜量越多，膜结构越致密。在亲水性较低的情况下，挂膜量是限制污水处理的主要因素，亲水性越强污水处理效果越好；在亲水性较高的情况下，膜结构成为污水处理的限制因素，亲水性增强对水处理有不利影响。比较不同亲水性填料的污水处理结果可知，表面酸处理所得接触角为62°的填料污水处理效果相对最好，COD和氨氮的平均去除率分别为87%和61%；其次依次为液面接触角41°、75°和87°的填料。

Abstract: The moving bed biofilm reactor (MBBR) was used to investigate the influence of carriers' surface hydrophilicity on the effect of wastewater treatment. Four kinds of K1 carriers with different surface hydrophilicities (water surface contact angle were 41°, 62°, 75°, and 87°) treated via oxidation, acid, alkaline and untreated were prepared and studied. The results showed that the stronger hydrophilic, the more quantity of microorganism hanged on carriers, and at the same time, the more compact of membrane structure. In the situation of low hydrophilic, the quantity of microorganism is a limiting factor of wastewater treatment; in the situation of higher hydrophilic, membrane structure becomes a limiting factor of wastewater treatment. Comparing with four kinds of hydrophilic carriers, surface contact angle of 62° was best for wastewater treatment, for which the average removal rates of COD and ammonia nitrogen were 87% and 61%, respectively. The order of others were carriers with water surface contact angle of 41°, 75° and 87°.
