Corresponding on 5th side of room 3 and the 6th side to be equipped with multiple grooves, then the muti-piece electrode plate is inserted into institute respectively
In the corresponding recesses for stating multiple grooves, as shown in Figure 2.
In embodiments of the present invention, as shown in Figure 1, further including in the tank house 3：Homogenizing plate 4 is installed on the water inlet
Between mouth 2 and muti-piece electrode plate 7, it is inserted into corresponding recesses；Between homogenizing plate 4 can make the discharge of sewage uniformly pass through electrode plate 7
Gap makes all electrode plates 7 uniformly and effectively participate in cell reaction, reduces electrode reaction rate difference and degree difference.
Specifically, an entire plate can be set into the homogenizing plate, it is evenly distributed on the homogenizing plate of this monolith more
A hole makes the gross area in multiple holes close to water inlet open area, and then the discharge of sewage uniformly passes through this some holes.It is also possible to set
Setting the homogenizing plate includes muti-piece, and the block number of homogenizing plate is identical as the block number of muti-piece electrode plate；The muti-piece homogenizing plate is in flat
Row arrangement, the muti-piece homogenizing plate are parallel with third side and the 4th side.The sky that is formed between any two of muti-piece homogenizing plate in this way
Gap is corresponding with the clearance position that muti-piece electrode plate is formed between any two, and makes the gross area in gap between homogenizing plate close to water inlet
Open area can also make the discharge of sewage uniformly pass through 7 gap of electrode plate in this way.
When not including homogenizing plate in the tank house 3, the number and muti-piece of the 5th side or the groove on the 6th side
The block number of electrode plate is identical, when in the tank house 3 including homogenizing plate, the number of the 5th side or the groove on the 6th side
The block number of block number and homogenizing plate including muti-piece electrode plate.
