A kind of high-efficiency coagulative precipitation tank
The utility model relates to the high-efficiency coagulative precipitation tank for Separation of Solid and Liquid in wastewater treatment.
Coagulative precipitation tank pond is generally before being used in biochemistry or the structures of heavy metal wastewater thereby mud-water separation, mostly is the mud that separating particles is thinner.The final purpose of sedimentation basin realizes Separation of Solid and Liquid, and in order to ensure the clarity of sedimentation basin upper liquid, the clay content as far as possible reducing upper draining is the place of process modification.The Chinese utility model patent of patent announcement CN203954750U discloses a kind of honeycomb inclined-tube sedimentation basin, comprises sedimentation basin body, is arranged at the stir chamber of sedimentation basin body one end, baffle plate and honeycomb settled layer; Sewage enters into stir chamber by water inlet, being stirred fully by mixer enters in the intrinsic dashpot of sedimentation basin, and baffle plate blocks sewage and makes it directly to enter sedimentation chamber, has cushioned the impact of water to baffle plate and honeycomb settled layer, meanwhile, sewage is prevented to pour in down a chimney from honeycomb settled layer top.Sewage upwards flows through honeycomb settled layer by the sedimentation chamber bottom sedimentation basin, the object utilizing the principle of shallow layer precipitating to reach mud to be separated with water, isolated mud is deposited in the sludge bucket of sedimentation basin body bottom portion along sedimentation pipe, isolated water continues to rise along sedimentation pipe, honeycomb settled layer was not had to reach water chamber, clean and clear water is overflowed by downflow weir, and discharges sedimentation basin body by delivery port.The sedimentation basin of this structure has the effect that sedimentation effect is good, the sedimentation time is short, deposition efficiency is high, improves the disposal ability of sedimentation basin.But, for the second pond that water content is higher, and the scene that water yield load impact is larger, the solid-liquid separation efficiency of the above-mentioned honeycomb beds of precipitation will be given a discount.
Utility model content
Technical problem to be solved in the utility model provides a kind of novel sedimentation basin for above-mentioned prior art, can improve the solid-liquid separation effect of sedimentation basin, significantly reduces the clay content of sedimentation basin top water outlet.
The technical scheme in the invention for solving the above technical problem is: a kind of sedimentation basin, comprise sedimentation basin body and coagulating basin, the side of described sedimentation basin body is separated out feed liquor buffering area by baffle plate, described coagulating basin and buffering area are connected at top, described sedimentation basin body communicates with the lower end of buffering area at baffle plate, described coagulating basin is configured with agitator, described sedimentation basin body bottom is provided with back taper bucket, described bucket connects discharge pipeline, described sedimentation basin body upper part is disposed with solid-liquid separator and honeycomb filler from the bottom up, default distance is kept between described solid-liquid separator and honeycomb filler.
Compared with prior art, the utility model has the advantage of: sedimentation basin body lower end is designed to back taper bucket, the sludge solids fixed point separated can be made to pile up, reduce the water content of mud, outside convenient, take out process; And honeycomb filler setting up and down and solid-liquid separator can improve the effect of Separation of Solid and Liquid, also can meet solid-liquid separation effect completely even if used as the second pond that sludge moisture content is higher by sedimentation basin, ensure the clarity of sedimentation basin top water outlet.
Accompanying drawing explanation
Fig. 1 is the structural representation of sedimentation basin in the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As shown in Figure 1, sedimentation basin in the present embodiment, comprise sedimentation basin body 1 and coagulating basin 2, described coagulating basin 2 connects waste water adapter 8, the side of described sedimentation basin body 1 is separated out feed liquor buffering area A by baffle plate 5, described coagulating basin 2 is connected at top with buffering area A, described sedimentation basin body 1 communicates in the lower end of baffle plate 5 with buffering area A, described coagulating basin 2 is configured with agitator 3, described sedimentation basin body 1 bottom is provided with back taper bucket 4, described bucket 4 connects discharge pipeline 9, described sedimentation basin body 1 top is disposed with solid-liquid separator 7 and honeycomb filler 6 from the bottom up, default distance is kept between described solid-liquid separator 7 and honeycomb filler 6, specifically arrange according to wastewater treatment capacity.
Sedimentation basin body 1 lower end is designed to back taper bucket 4, the sludge solids fixed point separated can be made to pile up, reduce the water content of mud, outside convenient, take out process; And honeycomb filler 6 setting up and down and solid-liquid separator 7 can improve the effect of Separation of Solid and Liquid, even if the system that water yield load impact is larger or use as the higher second pond of sludge moisture content and also can meet solid-liquid separation effect completely, ensure the clarity of sedimentation basin top water outlet.
In addition to the implementation, the utility model also includes other embodiments, the technical scheme that all employing equivalents or equivalent substitute mode are formed, within the protection domain that all should fall into the utility model claim.
