P
harmaceuticals and Personal Care Products (PPCPs) are
one of the most popular emerging pollutants. PPCPs
represent a large range of micro-pollutants, including
antibiotics, anti-inflammatory drugs, lipid-lowering drugs,
musk and hormones. PPCPs possess the features of high
persistence, bioaccumulation and low bioavailability,
therefore resulting in the long-term exposure to human, as
well as aquatic and terrestrial organisms. Based on the source
investigation, most of PPCPs are from domestic wastewater,
however, the urban wastewater treatment plant (WWTP)
can not guarantee the effective removal of PPCPs. In recent
years, several researchers already demonstrated microalgae
has good capability of the degradation of organic pollutants.
Thus, the present work focused on the degradation of five
typical PPCPs (Bisphenol A, Tetracycline, Ciprofloxacin,
Sulfadiazine and Sulfamethoxazole) and biofuel production
by Chlamydomonas sp.Tai-03. The concentration of
those PPCPs for batch tests was set at 1, 5 and 10 ppm,
respectively. The result showed that Tai-03 could completely
remove Bisphenol A, Tetracycline and Ciprofloxacin at 10
ppm in 145h, 170h and 120h, respectively. The removal
percentage of sulfadiazine and sulfamethoxazole was
both approximately 50% and 20% regardless with the
concentrations used. Furthermore, We also studied the
effect of photodegradation, hydrolysis and adsorption on
the removal of PPCPs. The photodegradation of bisphenol A,
tetracycline, ciprofloxacin, sulfadiazine and sulfamethoxazole
were 13.3%, 21.8%, 17.3%, 34.4% and 1.4%, respectively.
Hydrolysis rate of tetracycline, ciprofloxacin and sulfadiazine
was 48.9%, 9.8% and 2.5%, respectively. The hydrolysis of the
other two PPCPs and adsorption capacity was both almost
none. According to the analysis of five PPCPs’ degradation
intermediate products, open-loop reaction occurred in
Bisphenol A, Tetracycline and Ciprofloxacin, chain-breaking
reaction occurred in sulfadiazine and sulfamethoxazole.
These findings indicate micro-algea could be an efficient way
to achieve the effective degradation of these five PPCPs.
