[0024] The specific structure of the device in this embodiment is as described above, and will not be repeated here. The above-mentioned device was used to start the anaerobic reactor, and three sets of wastewater treatment devices were operated for comparison. The parameters of the device are as follows; the upper inner diameter of the UASB reactor is 19cm, the lower inner diameter is 11cm, the height is 50cm, the total volume is 6.6L, and the effective volume is 6.38L. The treated wastewater is wastewater containing chlorinated nitrobenzene.
[0025] Among the three groups of devices: R1 group is the traditional UASB reactor (excluding bioelectrode system), R2 group is the wastewater treatment device of the present invention whose cathode potential is controlled at -450mV, and R3 group is the invention whose cathode potential is controlled at -660mV Wastewater treatment plant. The three sets of reactors (R1, R2, R3) have a hydraulic retention time of 24h and an organic loa...
