Sludge press filtration treatment system and method

Abstract

The invention provides a sludge press filtration treatment system and method and relates to the technical field of sludge treatment. The sludge press filtration treatment system comprises a sludge pump, a press filter and a controller, wherein the sludge pump is connected with the press filter through a conveying pipeline, a pressure sensor is arranged on the conveying pipeline, and the controller is electrically connected with the sludge pump and the pressure sensor; the pressure sensor is used for detecting a pressure signal on the conveying pipeline and outputting the pressure signal to the controller, and the controller controls the operation state of the sludge pump according to the pressure signal. The technical problems that a current sludge dewatering treatment system is low in automation degree and low in treatment efficiency, the pressure is not stable in the sludge water conveying process, a sludge inlet system cannot be effectively controlled, and the service life and the press filtration effect of the press filter are affected are solved. Operation of a sludge pump is controlled according to pressure point location during sludge conveying of the press filter, the manual operation procedure is simplified, the intelligence degree is high, and the press filter operates stably.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a sludge filter press treatment system and a sludge filter press treatment method. Background technique [0002] The process of urbanization in our country is in the stage of accelerating, and the situation of environmental pollution is also increasing. The sludge problem has become a major problem related to people's life. The annual sludge output in my country is very huge and the weight is very alarming. At the same time, the total amount of sewage discharge in most cities is also showing a trend of accelerating increase, but the corresponding sewage treatment efficiency has not increased correspondingly, resulting in sludge discharge. And stacking has become a new major source of pollution. [0003] Current sludge treatment technologies include dewatering, thickening and drying of sludge. At present, the solid-liquid separation of sludge water can be achieved throug...

AI Technical Summary

Problems solved by technology

The current sludge dewatering treatment system is cumbersome to operate, with low degree of automation and low treatment efficiency. Moreover, due to the uneven distribution of sludge water, the pressure of sludge water in the transportation process is unstable, and the sludge feeding system cannot be effectively controlled, thus affecting the pressure.
