Abstract

The invention relates to the technical field of sludge treatment, and discloses a device for measuring a specific resistance parameter of sludge, a use method and an application thereof. The device comprises a filtering unit, a gas supply unit, a filtrate collecting unit, a mass weighing unit and a counting unit. In the invention, the gas supply unit provides filtering pressure for the filtering unit; a sludge sample is filtered in a sealed positive pressure space of the filtering unit; and a filtrate is obtained by the filtrate collecting unit and conveyed to the mass weighing unit to be weighed, the counting unit in data connection with the mass weighing unit automatically obtains filtrate mass and time interval data and records a curve of a filtrate volume and time to obtain a parameterb, manual reading is avoided, and counting errors of a traditional method are effectively reduced. In addition, the filtering unit is provided with a space for keeping complete sealing.

Description

technical field

[0001] The invention relates to the technical field of sludge treatment, in particular to a device for measuring the specific resistance parameter of sludge, a use method and an application thereof. Background technique

[0002] Sludge specific resistance is an important index to evaluate sludge dewatering performance, and it is widely used. Sludge specific resistance refers to the resistance of sludge filter cake per unit dry weight per unit filtration area under a certain pressure. At present, the method commonly used to measure the specific resistance of sludge is mainly the suction filter Buchner funnel method, which is complicated to operate and has a large counting error. Usually the Buchner funnel is determined by measuring the speed of the sludge filtrate filtration medium, that is, R=2pA 2 b / (μC). R is the specific resistance of the sludge, p is the filtration pressure, A is the filtration area, b is the slope of the straight line of the ratio T / V...
