Embodiment Construction

[0052] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0053] refer to figure 1 , is a kind of sludge treatment process disclosed by the present invention, comprising the following steps:

[0054] 1. A sludge treatment process, comprising the steps of:

[0055] (1) Desilting the river channel through dredging equipment and transporting through sludge pipelines;

[0056] (2) Send the sludge to the garbage sorting system for garbage sorting;

[0057] (3) The sludge is sent to the sediment separation system to remove sand and gravel in the sludge;

[0058] (4) Sludge is sent to the sludge storage tank, and a secondary sedimentation tank and a third-level sedimentation tank are set behind the sludge storage tank, and the overflow water in the third-level sedimentation tank is transported to the clean water tank;

[0059] (5) The drug dosing platform deploys the required chemicals, adds chemicals to the sludge out...

Abstract

The invention relates to a sludge treatment process. The process comprises the steps as follows: a river is dredged by a dredging device and sludge is conveyed by a sludge pipeline; the sludge is sentto a garbage sorting machine for garbage sorting; the sludge is sent to a sand scraping separation system to remove sand in the sludge; the sludge is sent to a first-stage sedimentation tank of a sludge storage tank, a second-stage sedimentation tank and a third-stage sedimentation tank are arranged behind the sludge storage tank, and overflow water in the third-stage sedimentation tank is conveyed to a clear water tank; a dosing platform blends required chemicals and adds agents to sludge output by the sludge storage tank, output sludge is mixed, conditioned and then conveyed into a concentration tank to increase sludge concentration, then, secondary dosing is performed before dewatering, the sludge is sent to a dewatering platform for dewatering, and filter pressing water produced by the dewatering platform flows back to the second-stage sedimentation tank; overflow water in the third-stage sedimentation tank is discharged to the clear water tank, water in the clear water tank is recycled or directly discharged to the river. A relatively efficient water recycling system is adopted and dependence on clean water is reduced.

Description

technical field [0001] The invention relates to the technical field of river channel dredging, in particular to a kind of sludge treatment. Background technique [0002] The patent with the publication number CN206562383U discloses a sludge dehydration and consolidation treatment system, including a pretreatment device for preliminary separation and treatment of the sludge, an adjustment device for dosing and homogenizing the mud after the preliminary separation treatment, A dehydration device for dehydrating and consolidating the liquefied mud; the pretreatment device, the regulating device and the dehydration device are connected in sequence. [0003] In the process of dredging mud treatment, there will be water circulation involved, but the above-mentioned technology lacks the reuse of water. Contents of the invention [0004] The purpose of the present invention is to provide a sludge treatment process, which has a relatively efficient water recycling system and reduc...
