Enter filtering ponds, avoids dirt from blocking water inlet, sewage is made at the uniform velocity to enter filtering ponds.
It is provided with Stirring leaf on the main shaft, is located above water inlet top cover.It is unfiltered after sewage enters filtering ponds
Solid easily blocks water inlet, and setting paddle is avoided that dirt deposits
The sediment tube pipe axis and the angle of level ground are 75 degree~85 degree.Suspended matter in water, solids occur poly-
The flocculate formed after heavy phenomenon, is accumulated into thin mud layer in sediment tube bottom side surface, slides back to collection mud layer, supernatant by gravity
Liquid can direct emission or reuse.
The precipitation tank cross section is regular polygon.Increase precipitation tank for precipitation response area, keep precipitation reaction more abundant, sinks
Shallow lake effect is more preferable.
The filter opening both ends are provided with strainer, and two strainers are arranged in each filter opening.By increasing strainer, further improved
Filter effect.
The filter opening number is at least six, and the level height at the filter opening center differs.Increase filter area, and can
Filter the sewage of different liquid levels, filter effect is more preferable.
The collection mud layer is provided with mud discharging mouth.Coagulation sludge is discharged into sludge-tank by sludge pipe and carries out otherwise processed or comprehensive benefit
With.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are:
1. a kind of power station sewage pretreatment tank of the utility model is saved by being arranged by filtering ponds in conjunction with sedimentation basin
Occupied area saves maintenance cost.
2. a kind of power station sewage pretreatment tank of the utility model uses sediment tube by setting, increases precipitation reaction face
Product, sedimentation effect are good.
3. a kind of power station sewage pretreatment tank of the utility model enters sewage at the uniform velocity by setting water inlet runner envelope
Filtering ponds avoid dirt from blocking water inlet, sewage are made at the uniform velocity to enter filtering ponds.
