Description
Technical field
The utility model embodiment relates to dirty waste water treatment process technology in sewage treatment plant, relates in particular to a kind of efficient mud-water separation settling system.
Background technology
Mud-water separation settling system is a kind of structures that application precipitation is removed suspension in water.Mud-water separation settling system is widely used in wastewater treatment, is generally the structures of mud-water separation before biochemical or after biochemical, mostly is the mud that separating particles is thinner.Before biochemistry, be called preliminary sedimentation tank, the mud inorganic constituents of precipitation is more, and moisture percentage in sewage sludge is lower with respect to second pond mud.Be positioned at biochemical sedimentation basin afterwards and be commonly referred to as second pond, mostly be organic sludge, moisture percentage in sewage sludge is higher.Sedimentation basin pond body plane is rectangle, and import is located at long one end, pond, and general employing flooded inlet opening, and water by inflow pond, equally distributed inlet opening body, is provided with baffle plate by inlet channel behind inlet opening, make current be evenly distributed in wide cross section, whole pond.The outlet of sedimentation basin is located at the long other end in pond, adopts downflow weir more, with ensure primary water after precipitation can be along pond the wide outlet canal that flows into equably.Before weir, establish scum silica frost groove and baffle plate to hold back water surface scum silica frost.Current part is the main body in pond.Pond is wide will ensure that with pond current are even along the cross-section of river water distribution in pond deeply, slowly and stably flows through according to design current velocity.The length-width ratio in pond is generally not less than 4, and the available depth in pond is generally no more than 3 meters.Sludge bucket is used for gathering the mud precipitating, be located at the bottom of the pond of front portion, pond more below,, there is discharge pipeline at the bucket end, regularly spoil disposal.
The pattern of mud-water separation settling system can be divided into three kinds of flat flow, vertical-flow and radial-flows by pool inner water flow path direction.The multiplex concrete of rectangular sedimentation tank is built, and also can use masonry masonry structure, or with the Tu Chi of masonry lining.Rectangular sedimentation tank simple structure, sedimentation effect is good, and stable work in work is used extensively.
The pond body plane of vertical sedimentation basin is circular or square.Waste water is entered in pond from top to bottom by the water inlet pipe that is located at sedimentation basin center, and umbrella-shaped baffle is divided in the outlet of water inlet, and waste water is uniformly distributed in pond, then along the whole section rising in pond.Suspension sinks to falling in the base cone shape sludge bucket of pond at Action of Gravity Field, and primary water is discharged from the downflow weir around of upper end, pond.Before downflow weir, also can establish scum silica frost groove and baffle plate, ensure effluent quality.
It is circular that radical sedimentation basin pond body plane mostly is, and also has square.Diameter is compared with large and the degree of depth is less, and diameter is 20～100 meters, and center, the pond depth of water is not more than 4 meters, and the periphery depth of water is not less than 1.5 meters.Waste water Zi Chi center water inlet pipe enters pond, and along radial direction to pond, week slowly flows.Suspension sedimentation in flowing, and enter sludge bucket along pond bottom sloping, primary water enters outlet canal from pond Zhou Yiliu.
In settlement of sewage process, spoil disposal is very important work in time.In sedimentation basin in sewage disposal, contained sludge quantity is more, has the overwhelming majority for organic matter, as spoil disposal not in time, will produce anaerobic fermentation, cause mud floating, not only destroy the normal work of sedimentation basin, and use water quality deterioration, and as dissolubility BOD value in water outlet rises, the lower degradation of pH value.The sedimentation basin of mechanical dredge will be strengthened the maintenance management of soil discharging facility, once mechanical dredge device fails should be repaired in time, to avoid pond prodelta clay mud excessive, affects effluent quality.In the time that spoil disposal is not thorough, should stop pond and adopt the clear mud of method of artificial flushing, all sewage in sedimentation basin need to be discharged but stop pond, affect the processed continuously efficiency of sewage.
