The intelligent high-efficiency treatment device for sludge dewatering according to claim 7, characterized in that, The control module determines the reason why the sludge dewatering treatment does not meet the preset standard according to the water level rising rate in the first sub-water storage cavity, If the water level rising rate in the first sub-water storage cavity is less than a preset rate threshold value, the control module determines that the reason why the sludge dewatering treatment does not meet the preset standard is that cleaning of the circulating filter cloth belt is substandard, and increases the power of the water pump to a corresponding value according to a difference between the preset rate threshold value and the water level rising rate in the first sub-water storage cavity; If the water level rising rate in the first sub-water storage cavity is greater than or equal to the preset rate threshold value, the control module determines that the reason why the sludge dewatering treatment does not meet the preset standard is that the roller pressing interval of the first group of pressure rollers is substandard, and decreases the roller pressing interval of the first group of pressure rollers to a corresponding value according to a difference between the water level rising rate in the first sub-water storage cavity and the preset rate threshold value. 9.The intelligent high-efficiency treatment device for sludge dewatering according to claim 8, characterized in that, The power increasing range of the water pump is positively correlated with a power adjustment difference value, and the power adjustment difference value is a difference between the water level rising rate in the first sub-water storage cavity and the preset rate threshold value.

10. An intelligent and efficient treatment method for sludge dewatering, based on the intelligent and efficient treatment device for sludge dewatering according to any one of claims 1-9, characterized in that, The method comprises the following steps: Step S1, feeding the sludge after pretreatment into the circulating filter cloth belt through the feeding port at a preset flow rate; Step S2, periodically obtaining water level values of separated water in the first sub-water storage cavity, the second sub-water storage cavity and the third sub-water storage cavity to determine the first dewatering characteristic value and the second dewatering characteristic value; Step S3, when it is preliminarily determined that the sludge dewatering treatment meets the preset standard based on the first dewatering characteristic value, continuing to dewater the sludge according to the current parameters, or additionally determining whether the sludge dewatering treatment meets the preset standard according to the second dewatering characteristic value; Step S4, when the preliminary determination based on the first dewatering characteristic value shows that the sludge dewatering treatment does not meet the preset standard, determining the cause of not meeting the preset standard according to the water level rising rate in the first sub-water storage cavity. Step S4, when the preliminary determination based on the first dewatering characteristic value shows that the sludge dewatering treatment does not meet the preset standard, determining the cause of not meeting the preset standard according to the water level rising rate in the first sub-water storage cavity.
