Problems solved by technology

However, there are also two problems in the discharge process: one is that the drainage point is relatively high, and gravity discharge cannot be realized; the other is that after gravity discharge is realized, the rise of the water level may easily cause backflow of the equipment in the season of abundant rainfall
These two factors will cause the sewage treatment equipment to fail to achieve normal treatment functions, seriously affecting the operation of the equipment and the lives of residents.
At present, there is no similar professional lifting equipment on the market, and the simple installation of valves will also affect the entire drainage process

Embodiment 1

[0030] Such as figure 1 As shown, the schematic diagram of the complete lifting device of the present invention; comprising a well shaft 2, a water inlet pipe 6 is installed on one side of the well shaft 2, and a submersible sewage pump 3 is arranged at the bottom of the well shaft, and the submersible sewage pump 3 Connect the lifting water pipe 4, and the lifting water pipe 4 extends from the bottom to the outside of the shaft 2; and a high water level float 5 and a low water level float 5 are arranged in the direction of the lifting water pipe; when gravity drainage cannot be realized , The treated sewage is directly discharged into the well shaft, and then the treated sewage is directly discharged to the storage area through the submersible sewage pump.

[0031] Further, a part of the well shaft 2 is buried in the soil body, and the other part is exposed to the air, and a manhole cover 1 is provided on the top; the part exposed to the air only accounts for a small part of ...

Embodiment 2

[0037] An integrated lifting device suitable for the sewage discharge of decentralized sewage treatment facilities, including a shaft 2, a water inlet pipe 6 is installed on one side of the shaft 2, and a drain pipe 9 is provided on the opposite side, and the height of the drain pipe is set to lower than the water inlet pipe; a water pump is provided at the bottom of the wellbore, the water pump is connected to the lifting water pipe, and the lifting water pipe extends from the bottom up to the outside of the wellbore; and the setting direction of the lifting water pipe is set There are high water level floats and low water level floats.

[0038] Further, a one-way valve 10 is provided on the drain pipe 9 .

[0039] Further, a part of the shaft 2 is buried in the soil, and the other part is exposed to the air, and a well cover 1 is provided on the top.

[0040] Further, after the riser 4 extends from bottom to top to the upper part of the shaft, it horizontally passes through...

Abstract

The invention provides a wastewater discharge integrated promotion device and method for decentralized wastewater treatment facilities, and belongs to the technical field of decentralized wastewater treatment in villages and towns. The device solves the problem of promotion of reasonable discharge after wastewater treatment. Based on full investigation of the characteristics of wastewater treatment and drainage, according to rural topography and wastewater treatment facilities drainage status, a concept of "integrated promotion" is put forward. As a wastewater treatment and discharge promotion device, the treatment device mainly comprises a shell body, a one-way valve, a submersible wastewater pump and a floating ball liquid level. The method and system comprise promotion devices comprising the submersible wastewater pump and the shell body, and achieve wastewater discharge when gravity drainage cannot be realized or when the water level rises in drainage area. The device, method and mode are professional promotion devices for decentralized wastewater treatment and drainage process in villages and towns, are adapted to the rural wastewater treatment facilities status, ensure the normal operation of the wastewater treatment equipment and protect the environment.

Description

technical field [0001] The invention belongs to the technical field of domestic sewage treatment for small residents, and in particular relates to a rural distributed sewage treatment and discharge system. Background technique [0002] With the development of village and town economy, sewage has seriously affected the water environment in rural areas. In recent years, in order to adapt to the relatively scattered living environment in rural areas, small decentralized buried sewage treatment equipment has been widely used. The sewage treated by the equipment is directly discharged to rivers or ditches. However, there are also two problems in the discharge process: one is that the drainage point is high, and gravity discharge cannot be realized; the other is that after gravity discharge is realized, the rise of the water level may easily cause backwatering of the equipment during the season of abundant rainfall. These two factors will cause the sewage treatment equipment to ...
