Abstract

The present invention relates to the technical field of wastewater treatment devices, in particular to a solid-liquid separation sewage lifting equipment, including a sewage tank, a solid-liquid separator is arranged in the sewage tank, one end of the solid-liquid separator is connected to the first water flow channel, solid-liquid The other end of the liquid separator is connected to the submersible sewage pump, the upstream of the first water flow channel is connected to the water inlet pipe and the sewage pipe, a first check valve is provided between the water inlet pipe and the first water flow channel, and a As for the second one-way valve, a self-priming device connected with the sewage tank is provided outside the sewage tank. In the present invention, a number of solid-liquid separators are arranged in the sewage tank, and several solid-liquid separators are arranged in parallel between the water inlet pipe and the sewage pipe. The multiple solid-liquid separators can be used to respectively store sewage and waste water in the sewage tank. The sewage in the sewage tank is discharged, and at the same time, it works uninterruptedly, which improves the work efficiency.

Description

technical field

[0001] The invention relates to the technical field of wastewater treatment devices, in particular to a lifting device for solid-liquid separation sewage. Background technique

[0002] In the basement of the building, building toilets is a common situation in the design, and the sewage generated cannot flow out by itself. At this time, no matter how many sanitary ware are installed in the bathroom, there are two more traditional methods: one method is to set up a sump under the basement floor, collect the sewage from the sanitary ware together, and use a submersible sewage pump to lift and discharge it to Outdoor underground sewage pump well; Another kind of method is all the sewage of toilet is discharged into outdoor underground sewage pump well by gravity, promotes and discharges into the sewage inspection well near the pump well with submersible sewage pump. There are three disadvantages in the first method: first, solid matter such as feces in the sewag...
