摘　　要：采用水产养殖中最常用的生物滤池工艺,以无纺布为填料处理模拟海水养殖废水和牙鲆养殖废水。通过改变水力负荷,研究了水力负荷对滤器性能的影响,并比较了以沸石、煤渣和塑料短管为填料的试验结果。结果表明,以无纺布为填料的滤器处理模拟海水养殖废水的氨氮容积负荷可达1.75g·m-3·h-1;亚硝酸盐负荷可达0.10g·m-3·h-1;处理牙鲆养殖废水时,氨氮和亚硝酸盐氮的负荷分别达2.52和2.34g·m-3·h-1。增大水力负荷可提高滤器的硝化性能。本试验中,最佳水力负荷高于处理生活污水的普通生物滤池的参数。The artificial marine wastewater and Japanese flounder （Paralichthys olivaceus） cultivation wastewater were treated with biofilter process often used in aquaculture by using non-woven fabric as media. The influence of hydraulic loading rate on filter performance was investigated by adjusting hydraulic loadings, and using zeolite, cinder and polythene pipes as the control media. The results showed that the removal rates of ammonia-N and nitrite-N in treated artificial marine wastewater with non-woven fabric filter were 1.75 g·m^-3·h^-1 and 0.10 g·m^-3·h^-1, respectively, while they reached 2.52 g·m^-3·h^-1 and 2.34 g·m^-3·h^-1 in Japanese flounder cultivation wastewater. The nitrification performance of filter would be better with the increase of the hydraulic loading rate. The optimized ranges of hydraulic loadings in our tests were above those of common biofilter for treating municipal sewage.
