Flocculating agent for rapidly purifying muddy water, and rapid purification method of muddy water

Abstract

The invention relates to a purification method of muddy water, in particular to a flocculating agent for rapidly purifying muddy water, and a rapid purification method of the muddy water, mainly aiming at solving the technical problems that in the prior art, the purification method of the muddy water is high in cost and low in efficiency; the muddy water, which very easily causes environmental pollution, is discharged into construction sites, municipal rainwater pipelines positioned beside the construction sites or sewer pipelines, so that the rainwater pipelines or rivers where the muddy water is discharged can be blocked. The purification method comprises the steps of separating large particles of suspended matters in muddy raw water by using a grate, and adding right amount of the prepared flocculating agent into the muddy raw water, wherein the flocculating agent is prepared by fully stirring and mixing divalent ionic type salt solid and anionic macromolecule organic solid powder, the divalent ionic type salt solid is a mixture of calcium salts and iron salts, and the adding amount of the flocculating agent is 1/1000-1/100 of the dry base amount of mud; fully stirring and mixing; then, enabling the obtained mixture to enter a sedimentation tank for carrying out precipitation, directly discharging precipitated supernatant, dewatering the precipitated mud and then transporting the mud to the outside.

Description

technical field [0001] The invention relates to a mud water purification method, in particular to a flocculant for rapid mud water purification and a purification method thereof. Background technique [0002] With the rapid development of urban infrastructure construction, there are more and more high-rise buildings and tunnel projects, and the construction of pile foundation projects is becoming more and more frequent. The mud water produced in pile foundation projects is a suspension liquid containing a certain amount of fine mud particles. , its mud content generally reaches 20%-50%, and its main components are colloids and fine suspended particles, so it has a certain viscosity and is difficult to separate after a long period of standing. At the same time, the stone production industry, especially the terrazzo production, will produce a large amount of muddy sewage with high alkalinity and high dispersion. At present, the conventional treatment method of this kind of mu...
