Description

Technical Field

[0002] Water treatment methods include physical treatment and chemical treatment. Humans have been treating water for many years. Physical methods include using filter materials with different pore sizes to remove impurities from the water through adsorption or barrier methods. The most important adsorption method is adsorption with activated carbon. The barrier method is to pass water through the filter material to prevent larger impurities from passing through, thereby obtaining cleaner water. In addition, physical methods also include sedimentation, which is to allow impurities with smaller specific gravity to float on the water surface and be fished out, or impurities with larger specific gravity to settle at the bottom and then be obtained. Chemical methods use various chemicals to convert impurities in the water into substances that are less harmful to the human body, or to concentrate the impurities. The oldest chemical treatment method should be to add alum to the water. After the impurities in the water gather and become larger in size, they can be removed by filtration. With the improvement of environmental protection awareness, water treatment technology has received widespread attention. Ceramic membrane filter is a set of precision super filtration and purification equipment that can be widely used in various fields.

[0026] Through parallel design, the system's processing capacity can be increased, while ensuring that the working pressure of each module is evenly distributed and extending the service life of the ceramic membrane material.

[0028] The output end of the first water pump 58 is connected to a transfer pipe 67, and the end of the transfer pipe 67 away from the first water pump 58 is connected to the series liquid inlet pipe 62 on the top of a group of serial ceramic membrane devices 61. Three groups of second water pumps 68 are arranged on the top of the serial mounting frame 3 and installed through the connecting frame. The output ends of the three groups of second water pumps 68 are respectively connected to the series liquid inlet pipes 62 on the tops of the other three groups of serial ceramic membrane devices 61. The input ends of the three groups of second water pumps 68 are connected to a connecting pipe 66, and the end of the connecting pipe 66 away from the second water pump 68 is respectively connected to the series liquid discharge pipes 63 on the three groups of serial ceramic membrane devices 61.

[0029] The ceramic membrane materials in the parallel ceramic membrane device 51 and the series ceramic membrane device 61 have good chemical stability and thermal stability, and can operate within a wide temperature and pH range, ensuring the stability of the effluent water quality. The ceramic membrane filtration technology does not require the addition of chemical agents, thus avoiding secondary pollution and energy consumption. It also has good durability and renewability, reducing the use and replacement frequency of raw materials.

[0030] A water inlet monitoring device 7 is provided on the surface of the water inlet pipe 56 at one end close to the water inlet valve 57, and a drainage monitoring device 8 is provided on the surface of the drainage pipe 69 at one end away from the series drainage pipe 63. A control system and a touch screen are provided on the control box 4, and the control system consists of a data acquisition module, a control algorithm module and an actuator control module.

[0031] The data acquisition module is responsible for collecting data from the water inlet monitoring device 7 and the water discharge monitoring device 8 in real time and transmitting it to the control algorithm module.

[0032] The control algorithm module calculates the optimal control strategy based on the preset filtering requirements and real-time data, and outputs the control signal to the actuator control module.

[0033] The actuator control module controls the actions of the water inlet valve 57, the parallel liquid inlet valve 54, the parallel liquid discharge valve 55, the parallel backwash mechanism 50, the first water pump 58, the series liquid inlet valve 64, the series liquid outlet valve 65, the series backwash mechanism 60 and the second water pump 68 according to the control signal, thereby realizing automatic adjustment and optimized operation of the system.

[0034] The control system has self-learning capabilities and can continuously optimize control strategies based on historical data and real-time data. The system has fault diagnosis and alarm functions and can promptly detect and handle abnormal situations. The control system supports remote monitoring and operation, allowing users to understand the system operating status at any time and make adjustments.

[0035] During use, wastewater first enters the parallel mechanism 5 through the water inlet pipe 56, and then enters the four sets of parallel ceramic membrane devices 51 through the four sets of parallel liquid inlet pipes 52 on the water inlet pipe 56 for preliminary filtration to remove most of the suspended matter and organic matter; The water initially filtered in the four sets of parallel ceramic membrane devices 51 is transferred to the drainage main pipe 59 through the parallel drainage pipe 53, and then the first water pump 58 is started to extract the wastewater in the drainage main pipe 59 and transfer it to a set of serial ceramic membrane devices 61 through the transfer pipe 67 for deep filtration. Then, by starting the three sets of second water pumps 68, the wastewater filtered in the first set of serial ceramic membrane devices 61 can be extracted and transported to the next set of serial ceramic membrane devices 61 through the connecting pipe 66 for deep filtration. The wastewater is deeply filtered in turn through the four sets of serial ceramic membrane devices 61 and finally discharged through the drainage pipe 69 on the last set of serial ceramic membrane devices 61, so as to further remove tiny particles and impurities and ensure that the effluent water quality meets the standards. The control system monitors the operating status of the wastewater and the effluent water quality in real time, and adjusts the working status of the parallel mechanism 5 and the series mechanism 6 according to actual needs. When a module fails or the pressure is too high, the control system will automatically switch to the backup module to ensure the continuous and stable operation of the system. The parallel mechanism 5 and the series mechanism 6 are also equipped with a parallel backwashing mechanism 50 and a series backwashing mechanism 60, which regularly clean and regenerate the parallel ceramic membrane device 51 and the series ceramic membrane device 61. During the backwashing process, the control system will automatically adjust the working status of each module to ensure the best backwashing effect without affecting the normal filtration process.
