Intelligent integrated sewage interception well

Intelligent integrated sewage interception well is an upgraded version of traditional sewage interception well. Compared with traditional sewage interception well, it not only has sewage interception function on sunny days, but also uses solar photovoltaic automatic charging to measure rainfall, and can adjust the rainfall value. It can judge by itself in different rainfall conditions, automatically open or close the gate, and achieve intelligent sewage interception.

Overview of intelligent integrated sewage interception well

On sunny days, some of the sewage in the pipeline flows into the sewage pipeline through the interception well, achieving zero direct discharge of sewage on sunny days.

When it rains, the initial surface rainwater is relatively dirty, and if it enters the river, it will cause pollution to the water quality of the river. Use a rain gauge to determine the amount of rainfall and allow the dirty initial rainwater to enter the sewage pipe.

In the middle and later stages of rainfall, the rainwater is relatively clean. It is directly discharged into the river through sewage interception wells to reduce the load of rainwater on the sewage network and ensure its normal operation.

When the water level in the sewage pipe is relatively high on rainy days, it is easy for sewage to overflow into the river. At this time, the drainage gate is automatically closed by the liquid level signal in the sewage interception well to prevent sewage from overflowing into the river.

When the water level in the river is relatively high during the flood season, it is easy for the river water to flow back into the sewage pipe. At this time, the overflow gate is automatically closed through the liquid level signal to prevent the backflow of river water.

Main components of intelligent integrated sewage interception well

The intelligent integrated sewage interception well is mainly composed of facilities such as wellbore, sewage interception gate, drainage gate, sewage lifting device, liquid level meter, rain gauge, grille, cloud monitoring platform, etc.

Main functions of intelligent integrated sewage interception well

The control of drainage gates, sewage interception gates, and water pumps is achieved through sensing instruments such as level gauges and rain gauges. The control methods and functions are as follows:

Sewage interception

Under the condition of low water level in the underground channel or downstream sewage pipe network, the drainage gate is closed on sunny days. The sewage in the underground channel or pipeline enters the interception well through the combined sewer pipeline and flows automatically to the downstream sewage pipeline. When the water level in the downstream pipeline is high, the water pump in the wellbore automatically starts and lifts the sewage to the treatment facility or to the downstream sewage pipe according to the water level in the wellbore, and can prevent river water from flowing back, achieving sewage pressure interception;

Initial rain flow restriction

At the beginning of the rain, the opening of the drainage gate is adjusted according to the water level inside and outside the well, and the opening of the sewage interception gate is adjusted according to the water quality and water level to limit the flow.

Rainy season direct discharge

As rainfall increases, the water level in the well rises and the water concentration decreases. When the preset water level is reached, the drainage gate begins to adjust its opening according to the water level, opening downwards to allow less polluted water to overflow from the upper layer. At the same time, the opening of the sewage interception gate gradually decreases to limit the interception flow. When the rainfall reaches a certain value, the drainage gate can be fully opened and the sewage interception gate can be closed, allowing rainwater to flow into natural water bodies and achieve direct drainage of rainwater.

Drain before rain

According to weather information, in the early stage of rainfall, close the sewage interception gate and start the submersible sewage pump to increase the power to discharge sewage, minimize the sewage in the combined pipeline network, and increase the storage space of the pipeline network itself. When rainfall begins, control the start and stop of the water pump and the opening of the drainage gate according to the water quality inside and outside the well.

Integrated monitoring and remote management system for sewage interception wells

The integrated sewage interception well is equipped with an advanced independently developed monitoring and remote management system, which can upload data to the cloud and achieve joint control of multiple sewage interception wells and multi-point rain gauges through central control, improving the efficiency of sewage interception and drainage work. In addition, based on dynamic water level and meteorological data, it can automatically control the opening and closing of gates and the start and stop of pumps, and achieve unmanned operation on sunny and rainy days. The development of various intelligent control devices and cloud based remote monitoring software has received high praise from society. Shanghai Kaitai not only customizes intelligent integrated sewage interception wells for customers, but also designs intelligent monitoring systems tailored for customers to ensure the smooth operation of sponge city management.
