Description
Technical field
The utility model is related to a kind of suction dredge more particularly to a kind of center-transmission single-pipe suction dredgers.
Background technology
The effect of secondary sedimentation tank is to make activated sludge sewage detaches with treated, and it is a degree of so that sludge is obtained
Concentration.Precipitation form in secondary settling tank is more complex, and precipitation initial stage is flocculation sediment, and mid-term is that stratification precipitates, and stage is pressure
Shrink mark forms sediment, i.e. sludge condensation.
The structure type of secondary settling tank:
The structure type of secondary settling tank is the same with primary sedimentation tank, can be divided into horizontal sedimentation tank, vertical sedimentation tank and radial-flow sedimentation tank.
Domestic existing municipal sewage plant's secondary settling tank overwhelming majority uses radial-flow, some medium and small treatment plants also to use flat flow,
And vertical-flow secondary settling tank is still rare.The construction and arrangement form and advection primary sedimentation tank of Flat Flow Final Settling Basin are essentially the same, only
Technological parameter is different.The horizontal erosive velocity of advection primary sedimentation tank is 50m/s, and the horizontal erosive velocity of secondary settling tank is 20m/s;When
When horizontal flow velocity is more than the scraper plate speed of travel of 20m/s or suction dredge more than 20m/s, the sludge to avale will be disturbed and be floated again
It rises.In addition to technological parameter difference, Radial Flow Secondary Sedimentation Tank and radial-flow primary sedimentation tank structural form are also substantially similar.It should be emphasized that
, the sludge discharge way and primary sedimentation tank difference of secondary settling tank be larger.Primary sedimentation tank be typically all first with mud scraper by sludge scraping to bucket,
It is intermittently or serially excluded again.And secondary settling tank is generally directly continuously excluded sludge with suction dredge.This is primarily due to activity
The easy anaerobism of sludge floats, and should be separated from secondary settling tank as soon as possible in time.In addition, aeration tank itself also requires continuously
Supplement returned sludge.Advection secondary settling tank generally uses purlin vehicle type suction dredge, Radial Flow Secondary Sedimentation Tank generally to use swinging suction dredge.
Common sludge discharge way has static pressure spoil disposal, air lift spoil disposal, siphon spoil disposal or direct pumping.It is external occur at present a kind of periphery into
The advantages of rectangular Radial Flow Secondary Sedimentation Tank of water peripheral effluent, although which takes up little area, but still there are following deficiencies:
1. because each single pond is limited by geometric dimension, therefore total number of divisions is more;
2. because total number of divisions is more, therefore water inlet water outlet gate and mud valve quantity are more;Increase equipment
Maintenance capacity, operational administrative are complicated;
3. effluent weir load is higher, effluent quality is influenced.
The type selecting of secondary settling tank:
In view of secondary settling tank and one of the important structures of Sewage Biological Treatment, operation quality directly affects water outlet water
Matter.Therefore, the design of secondary settling tank has a great impact to sewage disposal.Although rectangle sedimentation tank has many good qualities, and at present
There is new improvement pond type, it is contemplated that the large-scale sewage treatment plant of most domestic at present, primary sedimentation tank and secondary settling tank all use
Circle, without using compact rectangle sedimentation tank is taken up an area, reason removes round pool structure reasonable stress, easy for construction and section
It saves outside construction investment, mainly considers that the suction dredge of circular settling tank is easy to make, reliable for operation and maintenance load is few, pipe
Reason experience is ripe.
