Description
Technical field
The present invention relates to a kind of sludge drainage system for sedimentation basin.The system is mainly used in water treatment deposition technique,
By arranging rotation sludge pipe in bottom of pond, using suction force driving sludge pipe rotation caused by spoil disposal pumping mud, expand
Spoil disposal area, avoids bottom of pond portion from producing deposition.
Background technology
Sedimentation basin is one of processing structures common in water factory, it is strengthened by being used in combination with coagulation process
To there is the removal of the pollutants such as colloid in water, therefore it is widely used processing structures in water treatment technology.It is more normal at present
The sedimentation basin seen has horizontal sedimentation tank and inclined-tube sedimentation tank.In order to ensure the stability of sedimentation basin operation, sedimentation basin needs to set
Sludge drainage system, timely scavenger precipitation bottom of pond portion deposition, avoids deposition from excessively influencing sedimentation effect, causes alumen ustum to float, influence
Water water quality.For horizontal sedimentation tank, mainly siphon or pumping mud scraper are used.This mud scraper is more mature, is current advection
The mainstream mud scraper that sedimentation basin uses.But derive pond type for inclined-tube sedimentation tank or using other of inclined-tube sedimentation tank as prototype,
Sludge discharge way is then varied, such as center or peripheral drive sludge scraper, reciprocating mud scraper, gravity perforated pipe spoil disposal, air lift
Pump spoil disposal etc..Since inclined-tube sedimentation tank or its derivative pond type sedimentation time are short, pond type is compact, and the requirement to sludge drainage system is also compared
Higher, the optimization of sludge drainage system can directly improve precipitation process effect.Therefore, come for inclined-tube sedimentation tank and its derivative pond type
Say, sludge drainage system has certain Improvement requirement.
There is a kind of traditional sludge drainage system to arrange perforated sludge discharge pipe for bottom of pond, this fixed spoil disposal tube spacing is larger,
Easily there is spoil disposal blind area, sludge discharge effects are poor.In addition, the spoil disposal blind area between sludge pipe also easily produces bottom of pond deposition, when
Between long bed mud produce hardened, or block sludge pipe, be unfavorable for the normal operation of sedimentation basin.Therefore, sludge from sedimentation tank system is improved
The science of system is highly important with reasonability.
In addition, traditional perforated sludge discharge pipe is using bilateral perforate and is fixed on bottom of pond, the horizontal thrust that mud produces is inhaled in one side
The horizontal thrust that mud generation is inhaled by opposite side is offset, and acting not yet in effect, causes energy dissipation.Therefore, how the row of making full use of
It is also significant that suction force caused by mud, which does useful work,.
The content of the invention
, can by specific sludge pipe boring method it is an object of the present invention to provide a kind of sludge drainage system for sedimentation basin
