The influence to COD removal efficiency such as electrolysis time, pH value has carried out exploratory experiment, as follows as the result is shown:
Current density: trial stretch is from 0.1Acm-2According to 0.01Acm-2Incremental amplitude be gradually increased, and survey
COD removal efficiency situation is tried, as the result is shown: being 0.1-0.2Acm in current density-2Between range, with the increasing of current density
Greatly, COD removal rate is gradually increased, and speedup is larger, and increases to 0.2Acm in current density-2When above, COD removal
The speed that rate increases gradually decreases, and electrolytic efficiency is decreased obviously, and as current density is gradually increased, energy consumption is remarkably reinforced,
The electrode material proportion of goods damageds obviously increase；And pass through and in test the color throw of organic wastewater is observed and detected simultaneously,
As the result is shown are as follows: current density be 0.1-0.2Acm-2Between, COD removal efficiency is gradually increased, and electrolytic efficiency is higher, and

Two groups of comparative tests of Fe/Al bimetallic are not added by addition and in 10-15V, equally controlled in voltage in 1-10V, 15-30V
Deng range adjustment under, be added and do not add two groups of comparative tests of Fe/Al bimetallic, as the result is shown: being 1-10V in voltage
Between 15-30 in change procedure, addition assists the COD removal efficiency influential effect of electrolysis processing little with bimetallic is not added；
And voltage control in change procedure, is added by bimetallic, electrolysis is assisted to assist to be electrolysed than not adding bimetallic between 10-15V
The COD removal efficiency effect of processing is preferable, and removal efficiency is enabled to have apparent amplification；It can be seen that for using electricity
Voltage-controlled system is between 10-15V, it will facilitates Fe/Al bimetallic and assists electrolysis wastewater, removes COD.
(3) difference Fe/Al, which is added, assists to be electrolysed indigo Wastewater than bimetallic
