Sludge conditioning system and sludge conditioning method

Abstract

The invention provides a sludge conditioning system and a sludge conditioning method. The system comprises a sludge inlet pump and a filter press which are connected through a sludge inlet pipeline, and a conditioning mechanism, the conditioning mechanism comprises a conditioner adding unit, a detection unit, a mixing unit and a control unit, the conditioner adding unit is connected with the sludge inlet pipeline through a pipeline, the detection unit can detect the flow rate and concentration of sludge and the flow rate of a conditioner in real time, the mixing unit makes the conditioner andthe sludge mixed and reacted, and the control unit can adjust the adding amount of the conditioner according to the sludge with different flow rates and concentrations. The reasonable adding amount ofthe conditioner is adjusted by detecting the flow rate and concentration of the sludge in real time, so the efficiency and effect of sludge conditioning are improved, and the occupied area of a conditioning tank is saved.

Description

technical field [0001] The invention relates to a sludge conditioning system, in particular to sludge conditioning with low concentration and good fluidity. Background technique [0002] Sludge conditioning refers to measures to improve the properties of sludge in a planned way for economical follow-up treatment, aiming at improving sludge dewatering performance, improving the effect of mechanical dehydration and the production capacity of mechanical dehydration equipment. [0003] Under the prior art, the sludge is transported to the conditioning tank in batches, and the conditioning tank is equipped with a mixing device, and the conditioning agent 1 and the conditioning agent 2 are successively added to the conditioning tank and mixed evenly. The dosage of conditioner is adjusted artificially with the change of sludge volume, and the dosage is prone to large deviation due to human factors, and the conditioning equipment in batches occupies a large area, the conditioning pe...

AI Technical Summary

Problems solved by technology

The dosage of conditioner is adjusted artificially with the change of sludge volume, and the dosage is prone to large deviation due to human factors, and the conditioning equipment in batches occupies a large area, the conditioning period is long, and the conditioning efficiency is low The present invention directly adds conditioner to the mud inlet pipeline, detects the flow and concentration of sludge in real time through the detection module, and then controls the dosage of conditioner 1 and conditioner 2 through the closed-loop adjustment module to ensure that the conditioner The rationality of the dosage ensures the conditioning effect, improves the conditioning efficiency, and saves the area occupied by the conditioning pool
