At the control end, the control module 2 comprises an operation end 21, a memory 22 and a processor 23, the control module is used for controlling a low-pressure switch, a water inlet valve, a first backwashing valve, a second backwashing valve, a one-way valve and a protection valve in the water treatment system and receiving signals of the monitoring module, the monitoring module 18 comprises a thermometer 181, a water quality detection module 182 and a flowmeter 183, the three are sequentially arranged according to the water inlet flow direction, specifically, the thermometer is used for sensing the water temperature, and the water quality detection module is purchased as a scientific water quality detection device and is used for detecting the turbidity, the organic matter content, the trace element content and the like in water; the processor in the control module receives signals transmitted by the thermometer, the water quality detection module and the flowmeter, records and converts the signals (displaying the water temperature, the turbidity of the water body, the content of organic matters and the content of trace elements by an algorithm), displays the signals on the display module, records data, stores the data in the memory and refers the data when needed.
It is worth noting that the display module comprises a mobile terminal display and a device display, the water quality state can be displayed on the mobile terminal through the communication module, and the communication mode is WIFI and/or GPRS.
The operation end is used for the user to issue control command, in this scheme, mainly for clean operation of intelligence and filter core operation that resets.
It should be noted that the division of each module of the above apparatus is only a division of a logic function, and all or part of the modules may be integrated into one physical entity or may be physically separated in actual implementation, and all of the modules may be implemented in a form that software is called by a processing element, or all of the modules may be implemented in a form that hardware is called by a processing element, or part of the modules may be implemented in a form that software is called by a processing element, and part of the modules is implemented in a form of hardware.
The memory of the present invention has stored thereon a computer program which, when executed by the processor, implements a water treatment system for a water purification apparatus and a control method thereof.
The memory includes various media that can store program codes, such as ROM, RAM, magnetic disk, U-disk, memory card, or optical disk.
The Processor may be a general-purpose Processor, and includes a Central Processing Unit (CPU), a Network Processor (NP), and the like; the device can also be a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA) or other Programmable logic device, a discrete Gate or transistor logic device, or a discrete hardware component.
The control method of the water treatment system of the water purification equipment comprises intelligent cleaning operation and filter element replacement operation, wherein in the intelligent cleaning operation state, the water inlet valve 13 and the protection valve 16 are closed, the first backwashing valve and the second backwashing valve are opened, and water flows through the first backwashing valve 19, the first filter element 14, the second filter element 15 and the second backwashing valve 111 to complete the intelligent cleaning process.
The filter element replacement operation is performed according to the residual service life of the filter element on the display module 3, and the filter element is reset after replacement is performed on the control module 2.
The working conditions of intelligent cleaning are divided into three types:
under the water-supply state, the processor senses that the system is switched from the power-off state to the power-on state, starts a control signal, controls the water inlet valve and the protection valve to be closed, enters an intelligent cleaning mode, and displays the intelligent cleaning working state through the display module;
the water and electricity supply state is realized, and the program automatically enters an intelligent cleaning mode at the non-water time and at certain time points (such as 0 point in the morning or 2 points in the morning);
under the water-conducting and power-on state, the user directly enters the intelligent cleaning mode at the operation end.
The three working conditions combine automatic intelligent cleaning and manual intelligent cleaning, and the applicability of the system is effectively enhanced.
In the intelligent cleaning process, the material activation process generates a pore structure with a huge catalytic area, the surface area is 90 ten thousand square meters per cubic meter, and the material has a better adsorption catalytic action.
In the intelligent cleaning process of the first filter element and the second filter element, the hydroxyl on the surface of the material enables the surface of the material to carry strong negative charges, also called electromotive potential (zeta potential boundary potential), heavy metals, organic molecules and the like can be rapidly attracted, and when the materials are polymerized together, the filtration diameter is equivalent to 1-10 mu m, and turbidity can be removed.
The intelligent cleaning function ensures that the medium has the best contact area to ensure the electrochemical work (electron movement and the like), and under the action of a small amount of oxygen or an oxidizing agent, the catalytic surface can generate more abundant free radicals (free radicals) to enable the medium to be self-activated and sterilized.
Therefore, the filter material is reactivated through intelligent cleaning, and the corresponding filter material can be activated through each intelligent cleaning, so that the filter material is regenerated, and the service life of the filter material is greatly prolonged.
And the service life of the filter element is displayed, the processor receives the unit flow of the flowmeter and records the unit flow, the processor records the water consumption of each day, each week, each month and each year, and the residual service life of the filter element is expressed on the display end of the device, and the residual service life of the filter element is = (test service life-service flow)/test service life.
And at the equipment display end, when the residual life of the filter element does not reach a certain proportion, taking 3-10%, the filter element is expressed as green (normal color).
When the residual life of the filter element reaches a certain proportion, 1-10% of the filter element is taken, and the filter element is expressed as yellow (early warning color).
When the residual life of the filter element reaches a certain proportion, the filter element is less than 0-3 percent and is expressed as red (alarm color).
The user can select a proper time to replace the filter element according to the visual display, so that the filter element is intelligently reminded of replacement, and the safety, reliability and health of water quality are effectively guaranteed.
After the core is replaced, the filter element is reset at the operation end, the filter element can be reset, the service life of the filter element is recalculated, the residual service life of the filter element is displayed to be 100%, and the filter element is expressed as green (normal color).
