Gas-water separation semi-vacuum sewage lifting pump station

Abstract

The invention discloses a gas-water separation semi-vacuum sewage lifting pump station, and relates to the technical field of lifting pump stations, the gas-water separation semi-vacuum sewage lifting pump station comprises a pump station assembly, the input end of the pump station assembly is connected with a sewage source, the pump station assembly comprises a main shell and a wastewater input pipe, and the wastewater input pipe is fixedly arranged at the top of the left side of the main shell in a penetrating mode; the wastewater input pipe is connected with a vacuum floor drain lifter and a vacuum wastewater lifter in a sewage source, a sewage pretreatment mechanism is arranged at the top of the left side of the main shell, the sewage pretreatment mechanism is connected with a vacuum sewage lifter in the sewage source, and a waste gas driving mechanism is arranged at the top of an inner cavity of the main shell. While gas-water separation is achieved, waste gas is used for driving, effective and uniform mixing of sediments in water is achieved, meanwhile, use of a motor is avoided, the overhaul difficulty and the use cost are reduced, in addition, wastewater and sewage are input and treated respectively, and the treatment efficiency of the sewage pretreatment mechanism is effectively improved.

Description

technical field [0001] The invention relates to the technical field of lifting pump stations, in particular to a semi-vacuum sewage lifting pump station for gas-water separation. Background technique [0002] The sewage treatment plant generally adopts the gravity flow method to pass through various structures and equipment in the operation process. However, due to the limitation of the topography and geology of the plant area, a lifting pump station must be added to the treatment site to raise the sewage to a certain height before the gravity flow method can be used. In operation, the function of the sewage lifting pump station is to lift the sewage from the upstream to the height required by the subsequent treatment unit, so that it can realize gravity flow. The lifting pump is generally composed of a water pump, a water collection tank and a pump room.

Problems solved by technology

[0004] However, when the above-mentioned device is actually used by those skilled in the art, it is found that there are still some shortcomings. The more obvious one is that when the waste gas in the sewage is discharged, the power generated when the waste gas is discharged cannot be effectively used, resulting in a waste of energy.

[0005] At the same time, in order to avoid the situation that the sediment is accumulated and cannot be effectively discharged, it is also necessary to install a stirring motor at the bottom of the inner cavity of the pump station to drive the stirring blades. Although this can achieve the effect of stirring the sediment, due to structural limitations, the stirring effect is not ideal. , there is also the problem that the maintenance of the stirring motor is too difficult and the waste of electric energy

[0006] In addition, it is impossible to carry out targeted treatment for the sewage generated by the urinal, resulting in the waste water generated by the floor drain and the waste water generated by the washbasin. Basin wastewater basically does not contain solid debris, so this will lead to a reduction in the efficiency of urinal sewage treatment
