s300: when the resistance of the filter screen 110 to the sediment is larger than a first preset value, a second cleaning mode is started to clean the sediment; the first preset value is a maximum resistance value which can be received by the filter screen 110 when the sediment blocks the filter screen 110; or, when the resistance of the filter screen 110 to the sediment is greater than a second preset value, starting a third cleaning mode to clean the suspended solids; the second preset value is the maximum resistance value that the filter screen 110 can receive when the suspended matters block the filter screen 110; the total preset value is the sum of the first preset value and the second preset value.
In this embodiment, as shown in fig. 1, when the resistance of the filter screen 110 to the sediment is greater than a first preset resistance value, a second cleaning mode is started to clean the sediment; the method also comprises the following steps:
when the resistance of the filter screen 110 to the sediment is smaller than a first preset value, the pressure value of the sediment to the filter screen 110 is obtained, and when the filter screen 110 is blocked by the sediment, the resistance of the filter screen 110 is the resistance value of the filter screen 110;
when the pressure value of the sediment to the filter screen 110 is larger than a third preset value, the second cleaning mode is started to clean the sediment, and the third preset value is the maximum preset value of the pressure of the sediment borne by the filter screen 110; the sediment at the bottom is stacked, for example, the stacking of stones will have lateral pressure to the filter screen 110, and when the pressure to which the filter screen 110 is subjected is greater than the third preset value, it is indicated that the stacking of stones is higher, and therefore the sediment needs to be cleaned.
In this embodiment, as shown in fig. 1, the method further includes the following steps:
the pressure of the sediment received by the filter screen 110 and the resistance of the sediment received by the filter screen 110 in unit time are both increased, and then the sediment is blocked on the filter screen 110 and simultaneously the pressure is generated on the filter screen 110 by stacking the sediment, and the resistance of the sediment received by the filter screen 110 and the first preset value are judged again, so that whether the filter screen 110 is blocked or not, namely the resistance received by the filter screen is the priority detection data.
