Abstract
The utility model relates to a sedimentation tank for sewage treatment, which comprises a sedimentation tank, wherein a water outlet tank is arranged at the water outlet of the sedimentation tank. The utility model is characterized in that a water outlet weir is arranged on the water outlet tank, and a grille is arranged on the water outlet weir; and the grille is filled with filter membrane. The sedimentation tank of the technical scheme is suitable for the outlet water of the sedimentation tank of a small sewage treatment system, can ensure that the suspended matter in the outlet water is up to the standard, thereby ensuring that the heavy metal in the outlet water is up to the standard; and the sedimentation tank has very convenient manufacture, installation and maintenance, and better application effect.
Description
Technical field
The utility model step and a kind of sewage disposal device, particularly a kind of sedimentation basin that is used for sewage disposal.
Background technology
In the processing procedure of waste water, the precipitation that adopts various sedimentation basins to carry out harmful substance is removed, and realizes the recovery of metals resources simultaneously.Because the efficient of vertical sedimentation basin than rectangular sedimentation tank height, generally adopts in actual water and wastewater industry is handled.But because of sludge quality is in (mainly being to cause precipitating the complexity difference by the sedimentation coefficient difference) in the continuous variation, cause vertical sedimentation basin in draining, often occur being mixed with too much mud in the water, have the phenomenon of " race mud ", exceed standard heavy metals exceeding standard thereby go out aqueous suspension.
Summary of the invention
In order to overcome the weak point of above-mentioned sedimentation basin, the purpose of this utility model has provided a kind of sedimentation basin that is used for sewage disposal, and this sedimentation basin can solve the problem that the suspension that brings because of " race mud " problem too much reaches heavy metals exceeding standard.
For realizing this goal of the invention, the technical solution adopted in the utility model is:
A kind of sedimentation basin that is used for sewage disposal comprises sedimentation basin, and water outlet place of sedimentation basin top is provided with effluent trough, and it is characterized in that: effluent trough is provided with effluent weir, and effluent weir is provided with the hurdle lattice, in the hurdle lattice filter membrane is housed.
Described effluent weir is a zigzag.
Described filter membrane be the sponge filter membrane.
The sedimentation basin of technique scheme, be applicable to the sedimentation basin water outlet of small-sized sewage treating system (in the 1000t/d), adopt the sedimentation basin of technique scheme, can be not good at the sedimentation basin sedimentation effect, in the time of water outlet " race mud ", the suspension of failing in the sedimentation basin to precipitate is played the effect of interception, the suspension in the precipitated outlet water is filtered in filter membrane, the suspension that ensures water outlet is up to standard, thereby also ensured the up to standard of heavy metal in the water outlet.This device fabrication, installation and maintenance are all very convenient, and result of use is better.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the effluent weir schematic diagram that filter membrane is housed.
Specific implementation method
Referring to Fig. 1, Fig. 2, present embodiment relates to a kind of sedimentation basin that is used for sewage disposal, comprise vertical sedimentation basin 1, this vertical sedimentation basin 1 time is narrow widely, and water inlet pipe 2 feeds in the vertical sedimentation basins 1, and water outlet place of vertical sedimentation basin top is provided with effluent trough 3, effluent trough 3 is provided with zigzag effluent weir 5 near the upper end of water inlet 4 sides, zigzag effluent weir 5 is equipped with hurdle lattice 6 near water inlet 4 sides, is provided with sponge filter membrane 7 in the hurdle lattice 6, and 3 ends of effluent trough are provided with delivery port 8 and communicate with outlet pipe 9.
When the process of the water in the vertical sedimentation basin 1 zigzag effluent weir 5, the suspension of failing in the water to precipitate is by 7 interceptions of the sponge filter membrane in the hurdle lattice 6, can remove the invisible small suspension of bulky grain suspension and naked eyes, through going out in the current direction effluent trough 3 of sponge filter membrane 7.Avoided like this in the water quality instability, when sedimentation effect was bad, " race mud " situation of appearance had guaranteed the up to standard of suspension in the water outlet and heavy metal.
Filter membrane can be selected the raw material of unlike material, density for use according to different water quality situations, simultaneously, according to water yield and water quality situation, suitable hurdle lattice length and width is installed.
Claims (3)
