Stone sewage precipitation system

Abstract

The invention discloses a stone sewage sedimentation system, and relates to the technical field of stone processing. According to a technical scheme, the stone sewage sedimentation system comprises asedimentation tank, a track is arranged at the top of the sedimentation tank, a walking stirring box is arranged on the track, and the stirring box comprises a stirring box body, a walking mechanism is arranged at the bottom of the stirring box body, and a water inlet mechanism is arranged on one side of the stirring box body, a feeding mechanism is arranged on the other side of the stirring box body, and a stirring mechanism is arranged in the stirring box body. The invention has the beneficial effects that: the stirring box rotationally walking above the sedimentation tank is arranged, waterabsorption and stirring can be conducted while feeding is conducted, formation of sediments in the sedimentation tank cannot be affected in the full stirring process, and standing after stirring is completed is not needed; two kinds of stirring blades are arranged in the stirring box, one kind of stirring blades help full stirring, and the other kind of stirring blades prevent part of floccules formed in the stirring process from blocking a pipeline and discharging the floccules.

Description

technical field [0001] The invention relates to the technical field of stone processing, in particular to a stone sewage sedimentation system. Background technique [0002] The stone factory will produce a large amount of sewage during the production process. If it is not properly treated, it will not only cause environmental pollution, but also affect actual production. Therefore, stone sewage must be treated before it can be discharged and recycled. The generation of stone sewage is due to the processing of granite or slate through grinding, cutting, polishing, etc. during the stone processing process. Therefore, stone sewage contains a large amount of stone powder, residue and other substances, with high turbidity, and it is difficult to process through natural precipitation. [0003] The sewage generated during stone processing first flows into the sedimentation tank, and coagulants and coagulants are added to the sewage in the sedimentation tank, and under the action ...

AI Technical Summary

Problems solved by technology

Therefore, stone sewage contains a large amount of stone powder, residue and other substances, with high turbidity, and it is difficult to process through natural precipitation.

[0003] The sewage generated during stone processing first flows into the sedimentation tank, and coagulants and coagulants are added to the sewage in the sedimentation tank, and under the action of stirring in the regulating tank, the heavy metal ions mercury, lead and chromium in the stone production sewage During the rotation process, the impurities are fully condensed into larger particles, and then precipitated to completely separate the pollutants in the stone production sewage from the water, and the suspended solids in the sewage form stone mud at the bottom of the sedimentation tank; but there are One problem, the process of full stirring will affect the precipitation, and it can only be left to stand after the stirring is completed, which takes a long time
