Black smelly water is a manifestation of water body after it has been polluted by various organic substances and exceeded its environmental tolerance. It basically loses its use function and poses a serious threat to the urban ecosystem and the health of citizens. In this study, a laboratory-made compound microbial preparation was used to simulate the black smelly water body of Xidagou in Xixia District of Yinchuan City, Ningxia. The results showed that the degradation rates of CODcr, NH3-N and turbidity of black smelly water were 68.74 %, 80.13 %, 65.40 % and the growth rate of DO was 197.30% in the indoor simulation test, which were significantly different from those of the control(P<0.05);in the field test, the degradation rates of CODcr, NH3-N and turbidity of black smlly water were significantly different from those of the control(P<0.05). Degradation rates were 40.15 %, 56.89 %, 20.78 %, DO growth rate was 85.71 %, which provided technical support for the treatment of black and odorous water.
