Abstract

The invention relates to a device for measuring sludge specific resistance, in particular to a pressure filter type sludge specific resistance measuring device. It consists of two parts, the liftable support part and the sludge specific resistance measurement part, and there is a connecting device between the two parts; the main body of the liftable support part is a support platform, and the lower part is supported by a set of hydraulic support rods, which are installed on A platform with four lockable universal wheels; the sludge specific resistance measuring part has three main parts, including a metering tube, a Buchner funnel and a cylinder; there are sealing rings and pads between the Buchner funnel and the cylinder The filter medium is placed on the Buchner funnel; the cylinder is connected to the pressure buffer bottle through the connecting valve and the connecting pipe, and the connecting pipes are respectively equipped with sub-control valves. The invention can ensure the tightness of the device and the sludge filtration efficiency, the device has better mobility and stability, solves the problem of mutual influence between groups, and improves the measurement accuracy.

Description

technical field [0001] The invention relates to a device for measuring sludge specific resistance, in particular to a pressure filter type sludge specific resistance measuring device. Background technique [0002] Sludge specific resistance is the main indicator to reflect the dewatering performance of sludge, that is, under certain pressure conditions, the resistance of unit mass of dry sludge per unit filtration area, its size marks the performance of the same or different sludge after adding the mixture. Filtration performance, the smaller the sludge specific resistance, the better the filtration performance. At present, in the course of "Water Treatment Experimental Technology" in colleges and universities, in sewage treatment plants and related scientific research units, it is necessary to use sludge specific resistance measuring devices. Most of the sludge specific resistance measurement devices adopt the suction filter measurement method, which has troublesome disass...
