Effects of process principles and operating conditions on protozoan community structures in full-scale MWTPs in Beijing, China
INTRODUCTION In the artificial ecosystem of activated sludge, protozoa serving as primary consumers of bacteria and fungi as well as food sources for metazoa, construct an essential trophic link in food web and therefore make a numerically and functionally significant contribution. For building the species-habitat relationship, most previous studies have been devoted to inventorying protozoa as bio-indicators for predicting effluent quality and plant performance. Although the process principle of a treatment system, such as configuration, flow regime as well as aeration mode, etc., also affects the habitat of its microscopic individuals to some extent, its relationship with protozoan community has been poorly understood (Martin-Cereceda et al., 1996). As the largest developing country, China has built many wastewater treatment plants to meet the increasing municipal sewage and industrial wastewater. In order to facilitate the operation of these plants, the investigation of protozoan communities in full-scale municipal wastewater treatment plants (MWTPs) is of great significance.
