Abstract

Guangzhou municipal wastewater contains low organic matters and C, N and P ratios are not fitting for conventional biological treatment. A sequencing batch reactor (SBR) process was tested in municipal wastewater treatment. When sludge loading was 0.14～0.26 kg/(kg·d), the indices of effluent from SBR were as follows: BOD5 = 5.12～13.6 mg/L, COD Cr=10.7～32.2mg/L, NH 3-N= 2.83～9.23 mg/L and TP =0.1～0.45 mg/L.The result shows that using SBR to treat municipal wastewater with low content carbon and nitrogen is applicable.
