Abstract
The utility model relates to an active sand settling basin, and aims to provide an active sand settling basin capable of effectively separating settled sand from organic matters, so as to facilitate subsequent sand-water separation and the storage of the settled sand and improve the environmental sanitation of sand transportation and a stacking yard. The technical scheme of the active sand settling basin is that the active sand settling basin is provided with a sand settling basin, wherein a water inlet is formed at one end of the sand settling basin and a water outlet is formed at the other end of the sand settling basin; and the active sand settling basin is characterized in that a group of sand draining hoppers are arranged on the middle section of the sand settling basin and a gas stripping system and a sand draining system are arranged above the sand draining hoppers. The active sand settling basin is suitable for being used in a municipal wastewater treatment plant.
Description
Technical field
The utility model relates to a kind of active setting pot.Be applicable to the municipal sewage plant.
Background technology
Municipal sewage plant's pretreatment system generally adopts horizontal-flow grit chamber, rotational flow grit chamber or aerated grit chamber at present.After adopting the aerated grit chamber preliminary treatment, the raising that the dissolved oxygen in the water body can be has by a relatively large margin destroyed follow-up biochemical treatment unit anaerobism or anoxic effect, has caused the decline of denitrogenation dephosphorizing effect.Because the follow-up needs that denitrogenation dephosphorizing is arranged, most of sewage treatment plant more adopts advection and rotational flow grit chamber, and advection and rotational flow grit chamber generally adopt mechanical sediment outflow; Though solved the sediment outflow problem of setting pot; But owing to there is not the washed-out sand system, adhered to more organic matter on the sand setting of removal system, sand setting is in grit water separator medium sand separated form water difficulty; And corrupt easily smelly when banking up in the stockyard, influence the attractive in appearance of sewage treatment plant and brought certain atmosphere polluting problem.
Summary of the invention
The technical problem that the utility model will solve is: the problem that is directed against above-mentioned existence provides a kind of and can effectively separate sand setting and organic active setting pot, is convenient to depositing of later sand separated form water and sand setting, has improved the environmental sanitation in fortune sand and stockyard.
The technical scheme that the utility model adopted is: active setting pot; Have setting pot, the one of which end is a water inlet, and the other end is a delivery port; It is characterized in that: the interlude at setting pot is provided with one group of sediment outflow bucket, above described sediment outflow bucket, is provided with gas and carries system and sand-removing system.
Described gas is put forward system and is comprised that gas carries the gentle air inlet main of carrying of air intake branch, and gas is carried the air inlet main and is arranged on the outside of setting pot one sidewall and air inlet that gas is carried the air inlet main and is connected from air blast; Corresponding each sediment outflow bucket, carry the air inlet main from gas and draw a gas and carry air intake branch, the gas outlet that gas is carried air intake branch extends the centre bottom of sediment outflow bucket.
Described sand-removing system comprises sediment outflow main sediment outflow arm, and the sediment outflow main is arranged on the outside of another sidewall of setting pot; Corresponding each sediment outflow bucket, draw a sediment outflow arm from the sediment outflow main; The suction sand mouth of sediment outflow arm extends the centre bottom of sediment outflow bucket; The end that shakes out of sediment outflow main connects sand setting backflow electrically operated valve and sediment outflow electrically operated valve through threeway; The other end of sand setting backflow electrically operated valve inserts through pipeline near the water inlet of setting pot, and the other end of sediment outflow electrically operated valve is connected through pipeline and the storage sand pond that is located at the sand-removing system outside.
Described gas is carried air intake branch and is located " U " type in the gas outlet, and the gas outlet upwards.
The beneficial effect of the utility model is: the utility model is through the mode of control sand production rate; Increase sand and propose the system repeatedly washed-out sand in the intrasystem circulation of setting pot and through gas; Separate the organic matter that adheres on sand setting and the sand setting effectively; Be convenient to depositing of later sand separated form water and sand setting, improve the environmental sanitation in fortune sand and stockyard, thereby improved the pretreatment system of municipal sewage plant.

The specific embodiment
As shown in Figure 1, present embodiment comprises setting pot 9 and the water inlet 9-1, the delivery port 9-2 that are positioned at setting pot 9 two ends.At the setting pot interlude along water (flow) direction several funnel shaped sand deposition hopper 7 that are arranged side by side.Above sand deposition hopper, be provided with gas and carry system and sand-removing system.Gas is put forward system and is carried the air inlet main 5 gentle air intake branches 6 of carrying by gas and form.Gas is carried the air inlet main and is arranged on the outside of setting pot one sidewall and air inlet that gas is carried the air inlet main and is connected from air blast 10; Carry on the air inlet main 5 airbleed corresponding to each sediment outflow bucket 7 from gas and carry air intake branch 6, the gas outlet that gas is carried air intake branch 6 extends the centre bottom of sediment outflow bucket.Sand-removing system comprises sediment outflow main 3 and sediment outflow arm 4, and the sediment outflow main is arranged on the outside of another sidewall of setting pot, draws the sediment outflow arm corresponding to each sediment outflow bucket 7 from the sediment outflow main, and the suction sand mouth of sediment outflow main extends the centre bottom of sediment outflow bucket.The end that shakes out of sediment outflow main connects sand setting backflow electrically operated valve 1 and sediment outflow electrically operated valve 2 through threeway; The other end of sand setting backflow motor-driven valve inserts through pipeline near the water inlet of setting pot, and the other end of sediment outflow electrically operated valve is connected through pipeline and the storage sand pond that is located at the sand-removing system outside 8.
Sedimentation in sand deposition hopper 7 forms sand setting to sand through setting pot, and after sand setting was carried system improving through gas, it was back to into Shui Chu to part through 1 control of sand setting backflow electrically operated valve, and part is expelled to storage sand pond 8 through sediment outflow electrically operated valve 2; Adopt the mode of control sand production rate, increase sand and propose the system repeatedly washed-out sand, to reach the organic purpose that adheres on thorough separation sand setting and the sand setting in the intrasystem circulation of setting pot with through gas.Adopt electrically operated valve control in the actual motion, carry out the switching between sediment outflow electrically operated valve and the backflow electrically operated valve at set intervals; Or according to practical operating experiences, certain time sequence control is set, at set intervals sediment outflow once, the washed-out sand that in system, circulates of other times sand setting.
