Electrode module applied voltage regulates and controls to realize optimization process efficiency of the process unit to target waste water.
Beneficial effects of the present invention are further proved by following instance：
1. decolorizing azo dye waste water efficiency
The present apparatus is investigated to the treatment efficiency containing azo dye wastewater using intermittent water intake mode first, is given up according to target
Water water quality characteristic is mainly removed conversion using anaerobism and cathode module area azo dyes.It is individually continuous in anode module
It intakes, dyestuff is not contained in water, anaerobic zone and cathode module area individually intake, and dye strength is 80mg/L, electrode mould in water inlet
Block both ends applied voltage 0.7V, as shown in Fig. 2A, 2B, apparatus of the present invention SADB-BES is significantly faster than that list to the removal efficiency of dyestuff
Pure bio anaerobic device AD, after 5h, the dye strength of electrode district reduces to obtain 15mg/L, dyestuff in SADB-BES devices
Percent of decolourization reaches 72%, and sludge area also reaches 60% to the removal efficiency of dyestuff, is higher than the 55% of AD devices.
On this basis, water intake mode is changed to continuous stream mode, further investigates the stability and antithesis of apparatus of the present invention
The treatment efficiency of nitrogen waste water from dyestuff.Water inlet dye strength is divided into three gradients：50,70 and 90mg/L, applied voltage 0.7V, waterpower
Residence time HRT is 12h, as shown in Fig. 3 A, 3B, under the conditions of different water inlet dye strengths (50,70,90mg/L), and this hair
The electrode district water outlet of bright device SADB-BES is always maintained at highest percent of decolourization, respectively 92.9%, 93.2% and 87.7%, table
The removal of the bright coupled system azo dyes has apparent invigoration effect, this is because living things catalysis electrolysis zone utilizes electrode
The bioelectrochemistry on surface is reacted, and remaining dyestuff further orient quickly converts in so that anaerobic zone is discharged.Compare SADB-
BES from AD to the removal effect of waste water COD it can also be seen that under the conditions of different water inlet dye strengths, COD during the former is discharged
Removal rate is apparently higher than the latter, this is because on electrode module biomembrane enrichment, on the one hand increase the biomass of device, separately
One side electrode microorganism easily biodegradable organics using in water carry out reducing dye as electron donor, and the collective effect of the two promotes
The further removal of COD in water.This also demonstrates the validity of the present apparatus and method in terms of strengthening dye wastewater treatment.
2. electron recovery efficiency
Living things catalysis electrolysis zone in SADB-BES is calculated by the electric current of electrode, and the amount of the azo dyes of removal
Electron recovery efficiency, to characterize the contribution of living things catalysis electrolysis zone azo dyes removal.As shown in figure 4, electrode contribution rate into
Water dye strength reaches maximum when being 70mg/L, be 10.5%, when dye strength of intaking is relatively low (50mg/L), the contribution of electrode
Relatively low rate is 5.8%, when intake dye strength be increased to 90mg/L when, electrode contribution rate be 7.5%, this result shows that, when
When dye strength is relatively low, the dyestuff in waste water is largely removed by anaerobic zone, at this point, anaerobic organism reaction is to dyestuff in system
Removal play main function, when dye strength improves, the contribution rate of electrode district gradually increases, and shows electrode district to anaerobic zone
Dyestuff in water outlet plays the role of further strengthening removal, but when dye strength higher, coupled system SADB-BES is to dyestuff
Percent of decolourization also decline, dye load has been more than the processing load of system at this time, and the efficiency of electrode district is made to decrease, electrode tribute
It is also restrained to offer rate.
Particular embodiments described above has carried out further in detail the purpose of the present invention, technical solution and advantageous effect
Describe in detail bright, it should be understood that the above is only a specific embodiment of the present invention, is not intended to restrict the invention, it is all
Within the spirit and principles in the present invention, any modification, equivalent substitution, improvement and etc. done should be included in the protection of the present invention
Within the scope of.
