The cosmetics industry has been growing steadily for the past several years in China, yet very few researches exist on cosmetic wastewater treatment system. This study gave new insight to develop a combined anaerobic baffled reactor (ABR) and upflow biological aerated filter (UBAF) system for the treatment of cosmetic wastewater. The chemical oxygen demand (COD) removal efficiency in the cosmetic wastewater was mainly investigated in the front two compartments of ABR reactor, while it was treated by the same reactor with six compartments. When the influent COD load was set at 1.5 g COD/L.d, the COD removal efficiency reached a maximum in the No. 1 compartment. The highest COD removal efficiency achieved 2.0 g COD/L.d for the complete ABR reactor. The optimal hydraulic retention time (HRT) of the ABR was 48 h. A UBAF reactor was applied to advanced treatment for ABR effluent. The coke powder with the diameter of 0.5–1.0 mm and the gas-water ratio of 7:1 were chosen the optimal experimental conditio...

To reclaim the lignite-derived created during the dehydration procedure of lignite as cooling water; a laboratory-scale horizontal subsurface flow constructed wetland was designed to treat this lig...

Increased attention is currently being directed towards the potential negative effects of antibiotics and other PPCPs discharged into the aquatic environment via municipal WWTP secondary effluents. A number of analytical methods, such as high performance liquid chromatography technologies, including a high performance liquid chromatography-fluorescence method (HPLC-FLD), high performance liquid chromatography-UV detection method (HPLC-UV) and high performance liquid chromatography-mass spectrometry method (HPLC-MS), have been suggested as determination technologies for antibiotic residues in water. In this study, we implement a HPLC-MS/MS combined method to detect and analyze antibiotics in WWTP secondary effluent and apply a horizontal subsurface flow constructed wetland (CW) as an advanced wastewater treatment for removing antibiotics in the WWTP secondary effluent. The results show that there were 2 macrolides, 2 quinolones and 5 sulfas in WWTP secondary effluent among all the 22 antibiotics considered. After the CW advanced treatment, the concentration removal efficiencies and removal loads of 9 antibiotics were 53-100% and 0.004-0.7307 μg m(-2) per day, respectively.
