Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering. With the development of the times, integrated wastewater treatment equipment has also become relatively mature.

[0003] However, most wastewater treatment devices at present rely solely on sensors to collect data, which is not only time-consuming and inaccurate, but also makes maintenance complicated as the sensors are fixed to the device. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides an intelligent device for precise control of wastewater treatment, thereby solving the problems of low accuracy and complex maintenance of wastewater treatment devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an intelligent device for precise control of wastewater treatment, characterized in that it includes a shell and a base. The shell is divided into a collection chamber and an analysis chamber by a partition. A first inlet is provided on the side of the collection chamber and an outlet is provided on the side of the analysis chamber. A pipe is provided on one side of the partition of the collection chamber, and a four-way connector is provided on the other side, which penetrates the partition and connects to the pipe.
