Detailed Description
In order to make the purpose, technical solution and advantages of the present technical solution more clear, the present technical solution is further described in detail below with reference to specific embodiments. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present teachings.
As shown in fig. 1 and fig. 2, the present embodiment provides a sorting site sewage purification circulation system, which is used for recovering and purifying sewage after being used by a mineral sorting system, and includes a sewage pipe 1, a cyclone 2, a primary sedimentation tank 3, a cation stirring pump 4, a mortar pump 5, a filter press 6, a first drain pipe 7, a secondary sedimentation tank 8, a tertiary sedimentation tank 9, and a second drain pipe 10, wherein a water outlet end of the sewage pipe 1 is connected to a water inlet of the cyclone 2, a water outlet of the cyclone 2 is connected to the primary sedimentation tank 3, a water outlet of the sedimentation tank is connected to a water inlet of the secondary sedimentation tank 8, a water outlet of the secondary sedimentation tank 8 is connected to a water inlet of the tertiary sedimentation tank 9, the primary sedimentation tank 3 is provided with the cation stirring pump 4 for settling sewage solid particles through a stirring flocculant, a feed inlet of the filter press 6 is communicated with the sedimentation tank, the first drain pipe 7 is connected to the sedimentation tank, this first drain pipe 7 flows back to the sorting system through the chute, and first drain pipe 7 is used for exporting the elementary drainage water in the second grade sedimentation tank 8 and erodees the material, and second drain pipe 10 and tertiary sedimentation tank 9 intercommunication, second drain pipe 10 are used for exporting the clear water after tertiary sedimentation tank 9 handles.
Specifically, the sorting site sewage purification circulating system is installed on the ground, sewage of the system comes from the recovery and purification mineral sorting system, the sewage used by the recovery and purification mineral sorting system is directly discharged into the cyclone 2 through the sewage pipe 1, and after two-phase mixed liquid to be separated enters the cyclone 2 from the periphery of the cyclone 2 in a tangential direction under a certain pressure, strong three-dimensional elliptical strong-rotation shearing turbulent flow motion is generated. Because the particle size difference exists among solid particles in the sewage, the solid particles are subjected to different sizes of centrifugal force, centripetal buoyancy, fluid drag force and the like, under the action of centrifugal sedimentation, most of coarse particles are discharged through a bottom flow port of the cyclone 2, and most of fine particles are discharged through an overflow pipe, so that the purposes of separation and classification are achieved. In the technical scheme, the cyclone 2 can separate out the solids with large particle size in the sewage so as to realize the separation treatment of most of silt.
Sewage enters a primary sedimentation tank 3 after being treated by a cyclone 2, a filter press 6 is arranged inside the primary sedimentation tank 3, the filter press 6 applies certain pressure to the sewage by using a filter medium, so that liquid is dialyzed out, and the sewage is filtered again by the filter press 6, thereby further reducing solid particles in the sewage. Set up mortar pump 5 in the one-level sedimentation tank 3, mortar pump 5's effect is the solid sediment that absorbs 3 bottoms of one-level sedimentation tank, and the solid sediment is along with partial sewage together discharge one-level sedimentation tank 3 to reach the effect of clearing up 3 bottoms silt of one-level sedimentation tank.
Above-mentioned one-level sedimentation tank 3 is because the sewage of 2 outputs of swirler directly discharges into one-level sedimentation tank 3, inevitable subsidiary solid particle, consequently, adopts the technology of 3 centralized treatment most solid particles of one-level sedimentation tank, through the cooperation of pressure filter 6 and mortar pump 5, can clear away most solid particle in one-level sedimentation tank 3, and silt can discharge one-level sedimentation tank 3, and the effect of subsiding solid particle is obvious, and convenient to use does not need artifical pond maintenance down.
The cation stirring pump 4 arranged in the primary sedimentation tank 3 is used for fully mixing the cation mixed liquid with sewage in the sedimentation tank. Because the sewage contains a large amount of particles with smaller particle sizes, the particles with smaller particle sizes in the sewage can not be effectively settled after the settling process is carried out for a period of time, therefore, a cation mixed solution is put into the primary settling tank 3, the particles with smaller particle sizes are attached to form a cluster body with larger volume under the action of cation effective substances in the cation mixed solution, the process is a flocculation process, and the cluster body is discharged after being formed, thereby being beneficial to the removal of the particles with smaller particle sizes.
The discharged sewage directly gets into second grade sedimentation tank 8 after the settlement in first order sedimentation tank 3, and second grade sedimentation tank 8 further only subsides sewage, and at this in-process, the sewage reposition of redundant personnel of second grade sedimentation tank 8, partly sewage pass through chute recycle, and another part sewage gets into tertiary sedimentation tank 9. The sewage that divides through second grade sedimentation tank 8 gets back to mineral sorting system through the chute, and the clean degree of the sewage in second grade sedimentation tank 8 and satisfy the standard that mineral sorting system used, mineral sorting system use the sewage that second grade sedimentation tank 8 was retrieved, and the sewage after the mineral sorting system used enters into swirler 2 once more, forms the used circulation of part sewage.
The sewage discharged by the secondary sedimentation tank 8 after sedimentation directly enters the tertiary sedimentation tank 9, the sewage is treated by the third sedimentation process of the tertiary sedimentation tank 9 to obtain purified water, and finally the purified water is discharged from the tertiary sedimentation tank 9 for later use.
As preferred, the bottom of the primary sedimentation tank 3 is of a bucket-shaped structure, if the primary sedimentation tank 3 settles sewage, silt at the bottom of the tank is gathered at the bucket-shaped structure at the bottom of the tank, the bottom of the primary sedimentation tank 3 is also provided with a mortar pump 5, and a feeding port of the mortar pump 5 is arranged at the bottom of the primary sedimentation tank 3. The effect of the mortar pump 5 for adsorbing the silt is better.
The primary sedimentation tank 3, the secondary sedimentation tank 8 and the tertiary sedimentation tank 9 form a combined tank body with a square shape. The area of the first-stage sedimentation tank 3 is larger than that of the second-stage sedimentation tank 8 and that of the third-stage sedimentation tank 9.
The application method of the separation site sewage purification circulation system in the embodiment comprises the following steps that sewage discharged by a superior separation mineral separation system firstly enters a cyclone 2, most of sandstone in the sewage is filtered out by the cyclone 2, the sewage discharged by the cyclone 2 enters a primary sedimentation tank 3, cation mixed liquor is put into the primary sedimentation tank 3, cation active components in the cation mixed liquor are stirred by a cation stirring pump 4, the cation active components are fully combined with a mud mixture and then are gathered and separated out, precipitates in the primary sedimentation tank 3 are discharged out of the primary sedimentation tank 3 through a filter press 6 and a mud pump, the remaining sewage enters a secondary sedimentation tank 8, a water channel of the secondary sedimentation tank 8 is divided, one part of the water channel flows back to a chute of the separation system for washing materials, the other part of the water channel enters a tertiary sedimentation tank 9, and the sewage is settled by the tertiary sedimentation tank 9 to obtain purified water, purified water output by the third-stage sedimentation tank 9 flows back to the mineral separation process for reuse.
