Sewage treatment plants and sewage lifting systems

Abstract

The embodiment of the present invention relates to a sewage treatment device and a sewage lifting system. The sewage treatment device includes: a water inlet pipe, a solid-liquid separation tank, a one-way filter, a cut-off float, a water collection tank, a sewage pump and a water outlet pipe; solid-liquid separation The tank has a water inlet, a filtered water outlet and a sewage outlet; the sewage pump includes a pump body, a first connecting pipe and a second connecting pipe; the first connecting pipe is respectively connected to the one-way filter and the pump body; the second connecting pipe is connected to the pump When collecting water, the sewage flows into the solid-liquid separation tank from the water inlet pipe, and after being filtered by the one-way filter, the liquid part passes through the sewage outlet, the first connecting pipe, the pump body and the second connecting pipe into the water collection tank; the solid residue in the sewage is filtered by the one-way filter in the solid-liquid separation tank; when draining, the sewage pump starts to work, and the sewage in the water collection tank is pumped out by the second connecting pipe, pump body, The first connecting pipe and the one-way filter enter the water collection tank, and then are discharged from the outlet pipe through the sewage 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
