The sensor in this embodiment is a pressure sensor, that is, whether the filter element of the filtering apparatus needs to be backwashed or not is determined by detecting the pressure value at the water inlet 13 of the sewage treatment end of the barrel body of the filtering container 10 or in the water inlet passage in the barrel body 1, and/or at the filtered outlet 41 or in the water outlet passage in the barrel body 1; specifically, when more particles are attached to the filter element or the filter disc, the smooth passage of liquid such as water is prevented, so that the pressure value at the water inlet 13 is increased, and the pressure value at the outlet 41 is decreased after filtering, so that whether the filter device needs to be backwashed or not can be judged; similarly, when the flow sensor is used, when the amount of the particles attached to the filter element or the filter disc is large, the smooth passage of liquid such as water is prevented, and at this time, the flow rates at the water inlet 13 and the filtered outlet 41 are reduced, and it can also be determined whether the filter device needs to be backwashed. The pressure sensor or the flow sensor 883 is electrically connected with the control module 881, the control module 881 is electrically connected with the network communication module 882, the pressure flow sensor or the flow sensor is used for collecting pressure parameters or flow parameters of the operation of the filtering device, and the network communication module 882 is used for communicating with the outside; further, the control module 881 is used to read the parameters of the pressure sensor or the flow sensor 883, and when the parameters reach the first preset value, the parameters are fed back to the outside through the network communication module 882, and the control module 881 controls the filter device to perform the backwashing operation according to the received commands of the network communication module 882. Wherein, control module 881 is singlechip or PLC, and control module 881 in this embodiment is PLC, and network communication module 882 in this embodiment can be ethernet communication module, WIFI communication module or be 3G, 4G, 5G communication module again.

Specifically, in order to ensure the reliability or stability of the operation of the filtering device and enable the filtering device to flexibly adapt to different working conditions, the system also records the accumulated working time of the filtering device, for example, when the control module 881 detects that the accumulated working time of the filtering device reaches twelve hours or twenty-four hours, the control module 882 sends the back-washing information of the filtering device to the outside (manufacturer) and the manufacturer controls whether to execute the back-washing information; that is, the backwashing operation is performed based on the time as a reference value, and at this time, even if the pressure sensor does not reach the pressure value for backwashing, the control module 881 still sends backwashing information or performs backwashing operation on the filter device; further, when the backwashing process of the filter device is completed, the control module 881 records the operation time of the filter device again so as to determine the next backwashing cycle; of course, if the parameter of the pressure sensor or the flow sensor 883 reaches the backwashing trigger state before the time parameter value, the control module 881 sends backwashing information or performs backwashing operation on the filter device, and likewise, after the backwashing operation is finished, the control module 881 records the operation time of the filter device again so as to determine the next backwashing cycle; i.e. which comes first in the filter run time or the value of the pressure or flow sensor 883 during a backwash cycle of the filter.

In a preferred embodiment, the pressure or flow sensor 883 comprises M process-side sensors, M being a positive integer; the M processing end sensors are respectively arranged at the water inlet 13 or in the water inlet passage of the barrel body 1 of the filtering container 10, and/or the processing end sensor is arranged at the filtered outlet 41 or in the water outlet passage of the barrel body 1 of the filtering container 10, and the processing end sensor at least collects one parameter at the water inlet and/or the filtered outlet of the filtering device and sends the parameter to the control module 881; m in this embodiment is 2, although M may also be 3 or 4, for example, a redundant processing end sensor is added at the water inlet 13 and the filtered outlet 41 of the filtering apparatus; when the control module 881 detects that the parameter of the processing end sensor is higher than the first preset value, it sends a back-washing action signal. For example, the first preset value of the treatment end sensor at the water inlet 13 or the filtered outlet 41 can be set to 0.5MPA or 0.2MPA, which indicates that the sewage needs to be backwashed when the inlet water pressure reaches the value, or the outlet water pressure reaches the value; for another example, when the processing end sensor is respectively arranged at the water inlet 13 and the filtered outlet 41, the pressure difference between the sewage inlet pressure and the filtered outlet pressure can be calculated, the first preset value at this time can be 0.3MPA, which indicates that the backwashing operation is required when the pressure difference between the inlet water and the outlet water of the filtering device reaches 0.3 MPA.

Specifically, the backwashing is a process of reversely adding the attachments on the filter element or the filter disc to be removed, that is, clean water and compressed air are injected from the outlet 41 after the filtration to remove the attachments on the filter element or the filter disc, when the backwashing of the filter device is in operation, the attachments on the filter element or the filter disc are gradually removed, the injection pressure of the clean water at the time is gradually reduced, and when the pressure of the clean water or the intake air is lower than a second preset value, such as 0.1MPA, the cleaning of the filter device is completed.

Further, in a preferred embodiment, when the backwashing operation of the filtering apparatus continues to operate for a preset time, for example, five or ten minutes, the control module 881 obtains the current parameter value of the cleaning end sensor and compares the current parameter value with the initial value; when the control module 881 detects that the current parameter value is equal to the first preset value or higher than a third preset value, the control module 881 sends out failure information of the filtering apparatus, where the third preset value is smaller than the current parameter value, and the third preset value is greater than the second preset value. Specifically, the problem that the back-washing program cannot effectively solve is indicated that the filter screen or the filter disc of the filtering device is seriously blocked at the moment; at this point, the manufacturer can send the technician out again for field processing.
