Effect of short-term atrazine addition on the performance of an anaerobic/anoxic/oxic process

Changyong WU, Xiaoling LI, Zhiqiang CHEN, Yongzhen PENG,

Frontiers of Environmental Science & Engineering 2010, Volume 4, Issue 2,   Pages 150-156 doi: 10.1007/s11783-010-0020-9

Abstract: accidental pollution on the operation of a wastewater treatment plant (WWTP) in relation to Chemical OxygenThe specific NH NO reduction rate decreased slightly due to the short-term atrazine addition.The phosphorus removal rate was not affected by the short-term addition of atrazine under the appliedThe results of the oxygen uptake rate (OUR) showed that the respiration of nitrifiers decreased significantly

Reduction of wastewater toxicity and change of microbial community in a hydrolysis acidification reactor pre-treating trimethylolpropane wastewater

Xin Xing, Yin Yu, Hongbo Xi, Guangqing Song, Yajiao Wang, Jiane Zuo, Yuexi Zhou

Frontiers of Environmental Science & Engineering 2018, Volume 12, Issue 6, doi: 10.1007/s11783-018-1055-6

Abstract:

HAP was verified to reduce the toxicity of TMP wastewater effectively.

Actual TMP wastewater was fed in HAP with different dilution ratios for 240 days.

Formaldehyde, 2-ethylacrolein, TMP and 2-ethylhexanol were all greatly removed.

Firmicutes became the dominant phylum (the abundance increased to 57.08%).

Frontiers of Chemical Science and Engineering 2014, Volume 8, Issue 4,   Pages 387-404 doi: 10.1007/s11705-014-1457-3

Abstract: Nanocarriers have been designed to enhance their cellular uptake via endocytosis but following theircellular uptake, endosomal escape is the rate limiting step which restricts the value associated withthe enhanced uptake by nanocarriers.In this review, we first discuss different endocytic uptake pathways and endosomal escape mechanisms.we highlight the important design elements of recent virus-based nanocarriers for efficient cellular uptake
