Sewage treatment device and sewage lifting system

Abstract

The embodiment of the invention relates to a sewage treatment device and a sewage lifting system. The sewage treatment device comprises a water inlet pipe, a solid-liquid separation tank, a one-way filter, a cut-off floating ball, a water collection tank, a sewage pump and a water outlet pipe. The solid-liquid separation tank comprises a water inlet, a filtered water outlet and a sewage discharge outlet. The sewage pump comprises a pump body, a first connection pipe and a second connection pipe. The first connection pipe is connected with the one-way filter and the pump body. The second connection pipe is connected with the pump body and the water collection tank. During water collection, sewage flows into the solid-liquid separation tank through the water inlet pipe, and the liquid part is discharged into the water collection tank through the sewage drainage outlet, the first connection pipe, the pump body and the second connection pipe after sewage is filtered through the one-way filter. Solid residues in sewage are filtered out through the one-way filter and left in the solid-liquid separation tank. During sewage drainage, the sewage pump is started to work and pump out sewage in the water collection tank, and sewage enters the water collection tank through the second connection pipe, the pump body, the first connection pipe and the one-way filter and is discharged out of the water outlet pipe through the sewage drainage outlet.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage treatment device and a sewage lifting system. Background technique [0002] The sewage pumping station is a pumping station installed in the sewage pipeline system to pump up urban sewage. Because the sewage pipe is not like the water supply pipe (tap water), it has no pressure and needs to rely on the gravity of the sewage itself. Since the sewage collected by the urban sewage interception network pipe has a large area and is far away from the sewage treatment plant, it is impossible to bury the pipe It is very deep, so pumping stations need to be set up to raise the elevation of the sewage. Among them, the maximum particle passing rate and the energy efficiency level of the pumping station are important parameters of the sewage pumping station. In the environment where the country advocates energy conservation and emission reduction, it is of great practical significa...

Problems solved by technology

Due to the large area occupied by the traditional wet concrete sewage pumping station, the cost of land acquisition and civil construction is high; it is necessary to add a large cast iron copper-embedded gate and hoist, a rotary grille and a screening conveyor, and the equipment cost is high; it requires a person on duty to clean the screening , high labor costs; low pump efficiency, high operating costs

Due to the poor working conditions, the pump is easy to wear and block, the failure rate is high, and the maintenance cost is high. In recent years, it has been used less and less in recent years. It has been replaced by an integrated wet prefabricated pump station.

The integrated wet prefabricated pump station adopts the characteristics of prefabricated shaft, crushed grid, and automatic control, which solves the shortcomings of high cost of land acquisition and civil engineering, and the need for people to be on duty. However, it still has high equipment costs, low pump station efficiency, and pumps are easy to wear and block. shortcoming
