A novel textile wastewater treatment using ligninolytic co-culture and photocatalysis with TiO2

| description |
Textile industries produce effluent wastewater that, if discharged, exerts a negative
impact on the environment. Thus, it is necessary to design and implement novel
wastewater treatment solutions. A sequential treatment consisting of ligninolytic
co-culture with the fungi Pleurotus ostreatus and Phanerochaete crhysosporium
(secondary treatment) coupled to TiO2
/UV photocatalysis (tertiary treatment)
was evaluated in the laboratory in order to discolor, detoxify, and reuse textile
effluent wastewater in subsequent textile dyeing cycles. After 48 h of secondary
treatment, up to 80 % of the color in the wastewater was removed and its
chemical and biochemical oxygen demands (COD, and BOD5
) were abated in
92 % and 76 %, respectively. Laccase and MnP activities were central to color
removal and COD and BOD5
abatement, exhibiting activity values of 410
U L−1
and 1 428 U L−1
, respectively. Subjecting wastewater samples to 12 h
of tertiary treatment led to an 86 % color removal and 73 % and 86 % COD
and BOD5
abatement, respectively. The application of a sequential treatment
for 18 h improved the effectiveness of the wastewater treatment, resulting in
89 % of color removal, along with 81 % and 89 % COD and BOD5
abatement,
respectively. With this sequential treatment a bacterial inactivation of 55 % was
observed. TiO2 films were reused continuously during two consecutive treatment
cycles without thermic reactivation. Removal percentages greater than 50 % were
attained. Acute toxicity tests performed with untreated wastewater led to a
lethality level of 100 % at 50 % in Hydra attenuata and to a growth inhibition of
54 % at 50 % in Lactuca sativa. Whereas sequentially treated wastewater excreted
a 13 % lethality at 6.25 % and an inhibition of 12 % at 75 % for H. attenuata and L.
sativa, respectively. Finally, sequentially treated wastewater was reused on dyeing
experiments in which 0.86 mg g−1
adsorbed dye per g of fabric, that is equivalent
to 80 % of dye adsorption.
