The utility model relates to a railway station wastewater pump house, which comprises a wastewater pool arranged below the ground and a dry type installation pump arranged on the ground of the pump house, wherein a treatment pool and a water absorption pool for sand setting and soft water treatment are arranged in the wastewater pool;
furthermore, an overflow wall is arranged between the treatment tank and the water absorption tank, and wastewater overflows into the water absorption tank after passing through the treatment tank;
further, the treatment pool is arranged along the periphery of the water absorption pool;
further, the treatment tank is communicated with an automatic dosing device of the water softening equipment;
further, the wastewater enters a treatment tank through a wastewater pipe, and the wastewater pipe is arranged above the treatment tank;
further, the discharge port of the waste water pipe is arranged lower than the overflow wall of the treatment pool;
further, the waste water pipe is a DN300 nodular cast iron pipe;
further, the dry-type mounted pump is a lobe pump.
The utility model has the beneficial effects that: according to the waste water pump house for the railway station, disclosed by the utility model, after the waste water is subjected to sand setting and soft water treatment, the maintenance and replacement frequency of a water pump, a valve and a pipeline can be greatly reduced, and the maintenance cost is saved; after the water pump is changed into dry type installation, the working environment is improved, the service life is prolonged, and the maintenance is more convenient.
Drawings
The utility model is further described below with reference to the following figures and examples:
FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
Fig. 1 is a schematic structural diagram of the present invention, and as shown in the figure, the railway station wastewater pump house of the present embodiment includes a wastewater pool 1 disposed below the ground and a dry-type installation pump 6 disposed on the ground 2 of the pump house, a treatment pool 101 and a water suction pool 102 for sand setting and soft water treatment are disposed in the wastewater pool 1, wastewater enters the water suction pool 102 after passing through the treatment pool 101, and the dry-type installation pump 6 pumps the wastewater in the water suction pool 102 to a pressure inspection well 3 outside the pump house through a pressure wastewater pipe; after the wastewater is subjected to sand setting and soft water treatment, the maintenance and replacement frequency of a water pump, a valve and a pipeline can be greatly reduced, and the maintenance cost is saved; after the water pump is changed into dry type installation, the working environment is improved, the service life is prolonged, and the maintenance is more convenient.
In this embodiment, an overflow wall 103 is disposed between the treatment tank 101 and the water suction tank 102, and wastewater overflows into the water suction tank 102 after passing through the treatment tank 101; the overflow wall 103 is used for settling sand in the wastewater, so that the sand settling effect can be ensured, the structure is simple, the implementation is facilitated, and the economic cost is saved. Can set up a plurality of overflow walls 103 according to the space size, carry out multistage overflow and handle in order to improve the sand setting effect, be cascaded change between the overflow wall 103.
In this embodiment, the treatment tank 101 is disposed along the periphery of the water suction tank 102; the treatment tank 101 is arranged according to the water inlet direction, and for improving the efficiency, the treatment tank 101 may be arranged around the water suction tank 102, so that the water suction tank 102 is positioned at the center of the treatment tank 101 to improve the water inlet efficiency of the water suction tank 102.
In this embodiment, the treatment tank 101 is communicated with an automatic dosing device of the water softening equipment 4; the water softener 4 is an existing device for softening the wastewater in the treatment tank 101, and an automatic dosing device of the water softener 4 is also an existing structure and is used for regularly dosing the water softener into the treatment tank 101.
In this embodiment, the wastewater enters the treatment tank 101 through the wastewater pipe 5, and the wastewater pipe 5 is arranged above the treatment tank 101; because the wastewater pipe 5 is positioned above the treatment tank 101, wastewater flows into the treatment tank 101 in a free-fall manner, and the sand setting effect is improved.
