By this chance, I would like to thank Prof. Dr. -Ing. Knut Wichmann and Prof. Dr. -Ing.
Ralf Otterpohl so much for providing me this precious chance to accomplish this challenging
and meaningful research work. As the fatherlike supervisors, Prof. Wichmann and Prof.
Otterpohl supported both my work and my life constantly, whereby I can finally achieve my
doctorate.
I would like to heartily thank Dr. Joachim Behrendt. Besides the invaluable support and
input to my research work, he is also like an old brother taking care of me all long, which can
be never forgotten. I would like to cordially thank Dr. Claudia Wendland. In the often-raining
city of Hamburg she and her family made me feel like at home, which will be remembered as
long as I live. I would like to thank Dr. Martina Winker so much for her support, consideration,
generosity and patience. Especially, I am very grateful for her help to revise my dissertation. I
would like to thank Mr. Felix Tettenborn very much for being always considering me, and for
bringing me to another wonderful world. I would like to thank Mr. Kay Möller very much for
his plenty of help to my dissertation. Besides, I appreciate very much those profound
discussions with him and those touching encouragements from him. I would like to thank Mr.
Stefan Deegener so much for the light-hearted and jolly time, and for sharing my burden. As
the colleague, I thank Dr. Stefan Kohl very much for his help, understanding and kindness;
as the officemate, I enjoyed and appreciate very much the time that we spent in the same
office.
I would like to thank the programme of International Postgraduate Studies in Water
Technologies (IPSWaT) for financing my research work. Meantime, I would like to thank Dr.
Ulrike Schaub for being supportive and considerate to me and my research all the time.
I appreciate the whole Institute of Water Resources and Water Supply for providing such
comfortable conditions and ambience for scientific research. I appreciate the whole Institute
of Wastewater Management and Water Protection for always considering me as a family
member and giving me the considerable support.
Very special gratitude is for my parents and my sister. Without their support and
encouragements either in spirit or in matter, I would never be able to surmount all those difficulties
and go through all those tough days, and I could never reach this grand goal and have this
dreamy life. They are the best parents and the best sister for me.

Day and night, black and white, the world consists of two ultimate fringes. Traveling
between the two sides of the world, from birth to death, I draw my life with all my passion.
