Detailed description of the invention

The principles and features of this invention are described below in conjunction with the following drawings, the examples of which are set forth to illustrate the invention and are not intended to limit the scope of the invention.

First, after the activated carbon block 30 is completely soaked in the test water, the contaminated particles in the test water are adsorbed by the activated carbon block 30 (step 1). An activated carbon block 30 is loaded into an activated carbon capacitance type water quality detection system 20 as shown in fig. 1 (step 2). Under the elastic force of the elastic reed 5, the active carbon block 30 keeps good contact with the electrode 3. The system is started, the main controller 1 judges a current target to be detected through the voltage on the electrode electric control lead wire after obtaining running electric power through the power supply wire 13, the ultrasonic generator 2 is controlled to emit ultrasonic vibration through the ultrasonic generator electric control lead wire 11, the ultrasonic generator 2 is connected with the electrode 3 in a hard connection mode, the ultrasonic vibration can be efficiently acted on the active carbon block 30 through the electrode 3, and redundant water molecules in the active carbon block 30 generate ultrasonic cavitation effect under the action of the ultrasonic vibration to change into gaseous molecules to leave the active carbon block 30 (step 3). The main controller 1 applies a high-frequency electric field on the electrodes through the electrode electric control lead 12, the high-frequency electric field acts on the active carbon blocks 30, and the capacitance of the active carbon blocks 30 is continuously reduced because water molecules are continuously removed. When the capacitance is reduced and stabilized, which indicates that water molecules in the activated carbon block 30 are removed, the main controller 1 controls the ultrasonic generator 2 to stop working through the ultrasonic generator electric control lead 11, and records the final stable capacitance value of the activated carbon block 30 (step 4). The main controller 1 compares the final stable capacitance value of the activated carbon block 30 with the initial capacitance value of the activated carbon block 30 preset by the system, and calculates the water quality detection result according to the change value of the capacitance value (step 5). The main controller 1 controls the display 6 to display the corresponding detection result through the display electric control lead 14 (step 6), and the system mission is completed.
