Description
Technical field
The utility model relates to sewage treatment fields, and in particular to a kind of setting pot desanding system for sanitary sewage disposal
System.
Background technique
During sanitary sewage disposal, setting pot is the pretreatment carried out before biological treatment, carries out girt-water separation, is used
The clock-type rotational flow grit chamber built jointly with fine fack pond disjunctor.Its technique are as follows: collection sand-sediment outflow (sand-draining pump)-girt-water separation-mud
Sand (outward transport).
Currently, drain pipe is generally arranged that there are two kinds of settings on conventional setting pot:
1) the drain pipe setting of setting pot is in settling pit bottom sidewall, but the negative one of setting pot is arranged in setting pot lower half
Layer (or below earth's surface), and sediment outflow pipe bend is more, and sand-draining pump disengaging bore is smaller (40mm), and drain pipe is in big U-shape,
Outlet lift is only lower than setting pot water surface lift 55cm, and head is smaller.
2) the drain pipe setting of setting pot is connect in desilting bottom of pond portion, and with sand suction pipe, and sand suction pipe protrudes into sand setting bottom of pond portion,
Such as the Chinese utility model patent of Publication No. CN205759904U, which sucks sand suction pipe for sand setting and water, through sand trap
Drain pipe is conveyed, then by grit water separator by girt-water separation.
In use, there is sediment outflow bottleneck in above two device, sand-draining pump energy consumption is high, be easy to block, when dredging
It needing to cut off the water, artificial sand removal, setting pot base diameter only has 1 meter or so, and restricted clearance task difficulty is high, there are security risk,
And large labor intensity.As sewage quantity increases, the more aobvious protrusion of problem.
Summary of the invention
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of for the heavy of sanitary sewage disposal
The advantages such as sand pond desanding system, the system have structure simple, easy to operate, energy saving, and maintenance, repair cost of upkeep is low.
To achieve the above object, a kind of setting pot desanding system for sanitary sewage disposal designed by the utility model,
The system comprises the parts of setting pot to locate below ground level, and offers sand removing hole, the row in the setting pot bottom sidewall
The import of sand mouth and drain pipe connects, and the drain pipe passes through through-hole in stratum, and outlet is connected with grit water separator, the sand
Separator setting is in below ground, and grit water separator is lower than setting pot, and the sand grains outlet lower section of the grit water separator is set
It is equipped with conveyer belt, is provided with trolley below the other end of the conveyer belt.
Further, sand flash valve and sediment outflow maintenance are disposed between the setting pot and grit water separator in drain pipe
Valve.
Still further, being connected with backwash tube in drain pipe between the sand flash valve and sediment outflow service valve.
Still further, being provided with backwash valve on the backwash tube.
Still further, the setting pot includes the stirring pool on top and the settling tank of lower part, setting in the stirring pool
There is agitating device, the sand removing hole is arranged in settling tank bottom sidewall.
Still further, the stirring pool is above the ground level, the settling tank is lower than ground, and grit water separator is lower than sedimentation
Pond.
Still further, the drain pipe is transparent wired hose.
The utility model has the beneficial effects that
1) after elbow is reduced in the device of the utility model, sand setting bottom of pond portion sand flash valve and sediment outflow service valve 7 need to only be opened
Silt particle can flow automatically discharge；
2) the utility model eliminates sand-draining pump, the maintenance, repair maintenance of energy saving and pump；
3) transparent hose can clearly observe sediment outflow concentration situation of change, convenient and reasonable control sediment outflow time.
4) the utility model cancels sand-draining pump (power 4kw) one, calculates by operation 540min daily, annual to save electricity
Take: 0.8 (efficiency) × 0.6 yuan 540min/60min/ hours × 4kw ÷/degree × 365 days=9855 yuan；
In summary: the utility model saving is tired of the operator's block clearing dredging and maintenance personal's plant maintenance work of weight,
Reduce personnel labor intensity, improves work efficiency.
