Abstract
The utility model discloses an inspection shaft with a function of dephosphorization. An inlet end of an upstream pipe and an outlet end of a downstream pipe are fixedly connected to a lower shaft wall of a shaft body. A hollow cylindrical component is sleeved in the downstream pipe and the external diameter of the hollow cylindrical component is identical with the internal diameter of the downstream pipe. Sealing nets are fixedly connected to the openings at two ends of the hollow cylindrical component and the middle of the hollow cylindrical component. One end of the hollow cylindrical component is fixedly connected to the shaft wall through a connector. Phosphorous absorbent is disposed in an internal cavity of the hollow cylindrical component. When sewage flows through the inspection shaft, phosphate in the sewage can be absorbed to the absorbent, and accordingly, swage treatment plants can reduce anoxic zones of a biochemical pool in the prior art and further treatment cost of the swage is lowered.
Description
Technical field
The utility model relates to the sewage conduct field, specifically is to be used for the outdoor sewage separation in city and to the manhole of sewage dephosphorization.
Background technology
Municipal wastewater treatment plant mostly is in outer suburbs or urban fringe, could arrive Sewage Plant so sewage need rely on pipeline to carry at a distance.Sewage is in anaerobism or anaerobic condition in remote underground pipeline course of conveying, can discharge a large amount of phosphate, and the purpose of sewerage treatment is organic matter in the degraded water body, dephosphorization denitrogenation simultaneously.
The pH scope of most of sanitary sewages is 6.5～8; Temperature is at 10 ℃～20 ℃; The process of hydrolysis is very slow with this understanding; But in sewage, accelerated the hydrolysis conversion process under the effect of bacterium living beings enzyme greatly, so the many Quadrafos in the sewage had changed orthophosphates into before arriving the Sewage Plant processing.The existence of a large amount of orthophosphates makes Sewage Plant handle the load enhancing.
The sewage manholeIt is the inspection shaft of setting up on the sewerage system; Play inspection and clearing of pipeline, be connected pipeline section, pipe-line system ventilates; In conduit section change place, gradient change place, intersection, elevation change place manhole is set all generally; Also segmentation is provided with manhole on long straight line pipeline section, but present
ManholeDo not have the effect of disposing of sewage.
Summary of the invention
The purpose of the utility model is for the defective that overcomes above-mentioned prior art provides a kind of manhole with dephosphorization function, can in the sewage transport process, carry out the section processes of phosphorus, to reduce the sewage subsequent treatment cost.
The technical scheme that the utility model adopts is: be made up of well bore and well head; The entrance point of the affixed upstream tube of difference and the port of export of downstream tube on the borehole wall of lower wellbore section; Be with a hollow cylinder member that external diameter is identical with the downstream tube internal diameter in the downstream tube; The all affixed close-network in the both ends open place of hollow cylinder member and middle section, an end of hollow cylinder member has dephosphorization adsorbent through the affixed borehole wall of connector in the hollow cylinder member inner chamber.
The technique effect of the utility model is: when sewage is in anaerobism or anaerobic condition and discharges a large amount of phosphate in long drainage pipe; Whenever flow through manhole; Phosphate in the sewage can progressively be adsorbed by dephosphorization adsorbent and be attached on the adsorbent; Thereby make Sewage Plant can reduce the anoxic section in former technology mesophytization pond, reduced the cost of Sewage Plant.

The specific embodiment
Referring to Fig. 1, manhole is made up of well bore 2 and well head 1, on the borehole wall of well bore 2 bottoms, is fixedly connected the entrance point of upstream tube 3 and the port of export of downstream tube 4 respectively.Hollow cylinder member 5 of suit in downstream tube 4, the length of hollow cylinder member 5 is provided with water quality situation size, and the external diameter of hollow cylinder member 5 is identical with the internal diameter of downstream tube 4, selects for use drainage pipe commonly used to make.
The both ends open place of hollow cylinder member 5 and middle section all are fixedly connected the close-network 7 of good water permeability, and an end of hollow cylinder member 5 is fixedly connected on the borehole wall of well bore 2 through connector 6, is positioned at manhole delivery port place.Connector 6 can be expansion bolt or cementing agent etc.In hollow cylinder member 5 inner chambers, place dephosphorization adsorbent 8; The two ends of dephosphorization adsorbent 8 are closed net 7 and are fixed in hollow cylinder member 5 inner chambers; Dephosphorization adsorbent 8 is solid matters of a kind of porous or Large ratio surface, and for example natural zeolite has absorption affinity to phosphate anion in the water.The height of dephosphorization adsorbent 8 in hollow cylinder member 5 is consistent with the sewage degree of filling in the downstream tube 4.
The sewage of the port of export of downstream tube 4 is in non-flowing full state, and is in the state of a kind of anaerobism or anoxic, behind the dephosphorization adsorbent in hollow cylinder member 5, and organic matter and dephosphorization denitrogenation in the water body of can degrading.
Claims (2)
1. manhole with dephosphorization function; Form by well bore (2) and well head (1); The entrance point of the affixed upstream tube of difference (3) and the port of export of downstream tube (4) on the borehole wall of well bore (2) bottom; It is characterized in that: be with the external diameter hollow cylinder member (5) identical in the downstream tube (4) with downstream tube (4) internal diameter; The all affixed close-network in the both ends open place of hollow cylinder member (5) and middle section (7), an end of hollow cylinder member (5) has dephosphorization adsorbent (8) through the affixed borehole wall of connector (6) in hollow cylinder member (5) inner chamber.
2. a kind of manhole with dephosphorization function according to claim 1 is characterized in that: dephosphorization adsorbent (8) is that the solid matter and the height in hollow cylinder member (5) of a kind of porous or Large ratio surface is consistent with the sewage degree of filling in the downstream tube (4).
