Electron micrographs of the bamboo charcoal powder before activation and the bamboo charcoal powder after activation in example 4 are shown in fig. 1 and 2, respectively;
the relationship between the mass ratio of chitosan to the mixed powder and the sterilization rate in the electrode sheet of examples 4 to 11 is shown in fig. 3 (the abscissa represents the mass ratio of chitosan to the mixed powder, and the ordinate represents the sterilization rate);
the graphs showing the relationship between different activation patterns and sterilization rates of the electrode sheets of examples 1, 4, 12 and 13 under both of the power-on and power-off conditions are shown in fig. 4 and 5 (the abscissa is the test time and the ordinate is the sterilization rate).
The performance test method of fig. 2 and 3 is as follows:
firstly, adopting 50-by-50 single-side sterilization and desalination electrode plates as a positive electrode, adopting a pure titanium plate as a negative electrode, and enabling the space between 2 electrode plates to be 4mm, wherein the middle part of the electrode plates is provided with a wave-shaped flow channel which is a straight flow channel;
injecting 1L of water into the sterilization and desalination module from the container through a micro pump, and refluxing the water into the container from the other side to form circulation of a water path;
thirdly, the water pump starts to work after being electrified, and the test starts to time (in addition, the test of the electrifying mode is also carried out, and only when the water pump starts to work, the electrode plates are electrified simultaneously);
And fourthly, counting according to the national standard GB T5750.12-2006 Standard test method for domestic Drinking Water microbial indexes.
The electrode plate has the functions of sterilization and desalination, and the reasons are mainly that:
(1) chitosan is a powdery object, chitosan molecules have positive charges, when bacteria contact chitosan, the interaction between the positive charges of the chitosan and the negative charges on the bacterial cell membrane causes protease and other components in cells to leak, thereby achieving the antibacterial and bactericidal effects;
(2) the bamboo charcoal powder has large specific surface area, strong adsorption capacity to ions in water, and desalting function.
In addition, as can be seen from fig. 1 to 5:
(1) after the bamboo charcoal powder is activated by KOH, the specific surface area is greatly improved, and the adsorption capacity of the bamboo charcoal powder can be greatly improved;
(2) the sterilization efficiency is gradually increased along with the increase of the chitosan component, the sterilization rate is basically kept unchanged after reaching a certain degree, and then the sterilization rate is reduced along with the increase of the chitosan, and the mass ratio of the chitosan to the mixed powder is preferably 40-60%;
(3) the bamboo charcoal powder is activated, so that the bamboo charcoal powder not only has a desalting function, but also has a certain influence on sterilization, and pure chitosan has a sterilization effect, but only one surface layer can be contacted with water, namely only one surface layer is contacted with bacteria, so that the bacteria are killed. The activated bamboo charcoal powder can generate more nano holes, so that the specific surface area of the mixed powder is greatly increased, the adsorption capacity of cations is improved, the adsorption capacity of bacteria is improved, the stay time of the bacteria on the surface of the electrode plate is prolonged or the bacteria are completely adsorbed on the electrode plate, the contact chance and the contact time of the bacteria in water and chitosan are increased, and the sterilization efficiency of chitosan on the electrode plate is improved. In addition, the sterilization capability is increased along with the increase of the activation time, and the sterilization effect is best when the mass ratio of the bamboo charcoal powder to KOH is 1: 2;
(4) The electrode plates are electrified to form an electric field, positive and negative ions are transferred to the surfaces of the electrode plates by the electric field due to positive and negative charges, bacteria and the like also carry charges, and therefore the bacteria and the like can be transferred to the positions near the electrode plates by the electric field, and the antibacterial and bactericidal effects are greatly improved.

4. The water storage tank of claim 1 or 2, wherein: and the electrode sheet is connected with a metal probe which penetrates through the box body and is communicated with an external power supply.
5. The water storage tank of claim 1 or 2, wherein: two limiting parts which are in one-to-one correspondence with the electrode plates are arranged in the water storage cavity, the limiting parts are respectively close to the inner side walls of the left side and the right side of the box body, and accommodating spaces for accommodating the corresponding electrode plates are formed between the limiting parts and the adjacent inner side walls of the box body.
6. A method of controlling a water storage tank as claimed in any one of claims 1 to 5, comprising the steps of:
s1, starting a TDS detection device, detecting the water quality in the box body by the TDS detection device, transmitting the detected TDS value to a controller, and executing S2;
s2, the controller judges whether the TDS value is 0, if yes, S3 is executed, and if not, S4 is executed;
s3, judging that the box body is anhydrous, and executing S11;
s4, the controller judges whether the TDS value exceeds the set water quality standard TDS 0 If yes, go to S5, if not, go to S10;
s5, judging that the water quality in the box body does not reach the standard, electrifying the two electrode plates to generate an electric field, and recording the TDS value as TDS 1 Executing S6;
s6, the controller judges whether the electric field opening time T reaches the set time T 0 If yes, go to S7, if not, return to S6;
s7, cutting off the power of the two electrode plates, returning to S1,
S8, the controller judges whether the TDS value is less than the TDS 1 If yes, return to S4, if not, execute S9;
s9, judging that the electrode slice is invalid, and executing S11;
s10, judging that the water quality in the box body reaches the standard, and executing S11;
and S11, ending.
