采用新型弹性塑料填料生物膜法处理太湖入湖典型污染河流（林庄港）。中试规模的实验运行了约0.5年。结果表明，弹性塑料填料生物膜对高锰酸盐指数的平均去除率为5.4%，最大去除率为9.9%，对氨氮的平均去除率为5.35%~ 39.91%，对TP的最大去除率为28.6%。细菌学实验结果表明，高锰酸盐指数的去除率与异养菌数量的变化规律一致，氨氧化菌（AOB）和亚硝酸盐氧化菌（NOB）的数量与NH（4+）-N的去除率相匹配。
The biofilm process using a new-type elasticity plastic filler was adopted in a typical polluted stream entering the Tai Lake (the Linzhuanggang). The experiments at pilot scale ran for about 0.5 years. Results show the average removal percentage of permanganate index by biofilm attached to the elasticity plastic filler is about 5.4%, the biggest removal percentage is 9.9%, the average removal percentage of NH(4+) -N is approximately 5.35%-39.91%, the biggest removal percentage of TP is 28.6%. And the bacteriological experimental results show there is the same change laws between the removal percentage of permanganate index and the numbers of heterotrophic bacteria; the numbers of ammonia-oxidizing bacteria (AOB) and nitrite-oxidizing bacteria (NOB) are matching with removal of NH(4+) -N.
