%X By setting magnetic pieces in the Cr removal sludge system containing effective strains, magnetic field of 0~4.5 mT and 0~14 mT between pieces could obtained, and the verities of the given anaerobic sludge activity were studied, compared with the control. The results showed that the magnetic field intensity of 0~4.5 mT improved the activity of given sludge more effectively, both Umax.CH4 and methane producing volume per COD reached 64.3 mL CH4/g VSS·d and 0.140 mL CH4/mg COD, compared with the control, which increased by 20.6% and 70.7%, respectively. Meanwhile,it was found that magnetic field increased the efficiency of anaerobic sludge activity on transferring COD of wastewater to methane. The results were significant for the bio-treatment of the low organic load wastewater containing heavy metals.
