“…In the past decades, many attempts have been focused on blending plastic materials with cheap and biodegradable natural biopolymers, such as starch, cellulose, and chitin, to create new materials with desired properties [1][2][3][4][5][6][7][8][9][10][11][12]. These biopolymers, especially starch, are abundant, inexpensive, renewable, and fully biodegradable.…”

“…The Phanerochaete chrysosporium (Ph) was chosen since this fungus has been used in works concerning with the biodegradation of polymeric blends (Aitken and Irvine, 1989;Eriksson et al, 1990;Orhan and Buyukgungor, 2000). The strain Talaromyces wortmannii (BM-10) was chosen because it was not a pathogenic fungus besides it is the second species more common of the existent in soil, having been isolated in several continents (Domsch and Gams, 1980).…”

“…Orhan and Buyukgungor (2000) studied the biodegradability of polyethylene films in soil and found that the soil with higher microbial enrichment showed higher degradability capacity of polyethylene films. However, in our previous study, the same fiber was used to treat urban stormwater but no indication of the release of organic matters was observed, which may be due to the low microbial population in the urban stormwater (Chen et al, 2013).…”

prevention of piggery stormwater is of vital difficulty due to the dispersibility and uncertainty of the occurrence and the pollution source. Piggery stormwater has attracted more and more attention, since it contains high concentration of nutrients (e.g. nitrogen, phosphorus and organic matters), toxic substances (e.g. ammonia, nitrate and toxic organics) and risky pathogens and bacterial. It pollutes rivers and seas (Al-Hafedh et al., 2003;Mearns et al., 2013) AbstractA set of lab-scale polymer synthetic fiber packed column wetlands composing three columns (CW1, CW2 and CW3) with different hydraulic regimes, recirculation frequencies and pollutant loading rates, were operated in 2012. Synthetic fiber tested as an alternative wetland medium for soil mixture or gravel which has been widely used, has very high pore size and volume, so that clogging opportunity can be greatly avoided. The inflow to the wetland was artificial stormwater. All the wetlands achieved effective removal of TSS (94%~96%), TCOD (68%~73%), TN (35%~58%), TKN (62%~73%) and NH 4 -N (85%~ 99%). Particularly, it was observed that COD was released from the fiber during one distinct period in all wetlands. This was probably due to the degradation of polymer fiber, and the released organic matters were found to serve as carbon source for denitrification. In addition, with longer retention time and frequent recirculation, lower effluent concentration was observed. With higher pollutant loading rate, higher nitrification and denitrification rates were achieved. However, although organic matters were released from the fiber, the lack of carbon source was still the limiting factor for the system since the release persisted only for 40 days.
