Abstract

The invention relates to a slurry dehydration combined system, which is characterized in that: one end of a mixer is provided with a slurry inlet and a medicament inlet, and the other end of the mixer is provided with an outlet; a slurry pump is arranged in a slurry turnover box and serially connected with a slurry concentration detector and a second flowmeter in turn through a pipeline and then connected with the slurry inlet on the mixer; a medicament diluent box comprises a medicament box and a diluent box; a medicament outlet is formed on the medicament box, and a diluent outlet is formed on the diluent box; the medicament outlet and the diluent outlet are connected with a first electromagnetic valve and a second electromagnetic valve respectively; the first electromagnetic valve and the second electromagnetic valve are in parallel connection through a pipeline and then serially connected with an electromagnetic valve, a medicament delivery pump, a first flowmeter and a first electric valve in turn; the first electric valve is connected with the medicament inlet on the mixer; and the output on the mixer is connected with the input end of a centrifuge through a pipeline. The invention has high work efficiency and purification efficiency and can realize large-scale centralized treatment.

Description

technical field [0001] The invention relates to a mud dehydration combined system, which belongs to the fields of environmental engineering and construction engineering. Background technique [0002] With the intensification of river management, large-scale cleaning of river silt has produced a large amount of mud. In the process of urban construction, a large amount of construction mud is produced in the construction of underground buildings and the construction of foundation piles. The existing mud treatment generally adopts the following method: use automobiles and ships as transportation tools to gather the mud generated from various places together, and then adopt the technology of dosing flocculation reaction, that is, the mud passes through the flocculation reaction tank, the coagulation aid reaction tank and the mud-water separation in sequence. The pool gets clean water. The flocculant is added to the flocculation reaction tank, and the coagulant aid is added to t...
