Abstract
Abstract. Sufficient dissolved oxygen (DO) is one of the important factors on the treatment of contaminated water by using aerobic microbes. So that oxygen transfer becomes one of the hot spots on the research and development of the wastewater treatment engineering. Oxygen transfering is intensified by the accelerator for biological reaction. In this paper, the schoolyard domestic sewage was processed by the method of sequencing batch reactor (SBR) activated sludge processing. Some important factors, e.g. the dosage of the accelerator for biological reaction, and the effect of the aeration time and intensity on the CODCr removal efficiency have been investigated, the optimum conditions have been chosen.
