title: [Elasticity plastic filler for purification of polluted streams in situ entering lake].
abstract: 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.
