In this paper, Kevlar or Polysulfonamide (PSA) pulp were used to replace plant fiber pulp partially or completely and by adjusting their ratios and a variety of Kevlar or PSA pulp reinforced activated carbon fiber paper (ACFP) were prepared via wet-laid paper making technology. The influences of addition of Kevlar or PSA pulp on the permeability, mechanical property, filtration performance, adsorption property of ACFP were discussed by maintaining the addition content of activated carbon fiber unchanged. Results showed that with the addition content of Kevlar or PSA pulp increased, the permeability and filtration performance of ACFP decreased obviously, while the bursting strength and the static CCl4 adsorption performances were firstly increased and then decreased. Generally, the permeability and filtration performance of Kevlar pulp reinforced ACFP were slightly worse than that of PSA pulp reinforced ACFP, while the bursting strength as well as the static CCl4 adsorption properties of Kevlar pulp reinforced ACFP were better than that of PSA pulp reinforced ACFP.

Biofilms on fiber-based carriers have attracted much concern in wastewater treatment processes recently. In this study: (1) a novel sandwich structure fiber-based biofilm carrier was produced, which consisted of an inner core composed of polyacrylonitrile-based activated carbon fiber felt (PAN-ACFF) and an outer coat made of polyester reticular cloth with polypropylene fiber loops; (2) the novel carrier was filled in a step-feeding pilot-scale modified University of Cape Town process (MUCT) for sewage treatment; the MUCT contained a series of pre-anoxic/anaerobic/anoxic-1/anoxic-2/oxic tanks, wherein nitrification liquor was recycled to the anoxic-2 tank and an extra liquor return from the anoxic-1 to the pre-anoxic tank was set up; and (3) the removal efficiencies of chemical oxygen demand (COD), total nitrogen (TN) and total phosphorus (TP) were continuously tested for two periods as operational parameters alternated. The optimum values were collected in Period II, when the influent loads were 2,100.6 ± 120.3 gCOD/(d m3), 205.5 ± 20.4 gTN/(d m3), 39.9 ± 3.9 gTP/(d m3), the removal percentages were 93.1 ± 1.1% of COD, 39.4 ± 3.5% of TN, and 84.6 ± 3.4% of TP. For COD, NH4+-N, and TP, the specific removal loads of filler were 291.5 ± 18.2, 22.9 ± 3.1, 4.8 ± 0.5 (g d)/kg.
