[0002] Wastewater treatment is the process of purifying sewage to meet the water quality requirements for discharge into a water body or reuse. Wastewater treatment is widely used in construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, catering and other fields.

[0003] According to a sewage pipe sludge blockage dredging device disclosed in patent application No. 202223115468.4, its technical solution is to open the nitrogen valve, first the third solenoid valve works, the third solenoid valve is opened, nitrogen is input from the nitrogen main pipe, and is ejected through the third nitrogen gun after passing through the third air inlet pipe. After 10 minutes, the second solenoid valve works, the second solenoid valve is opened, nitrogen is input from the nitrogen main pipe, and is ejected through the second nitrogen gun after passing through the second air inlet pipe. After 10 minutes, the first solenoid valve works, the first solenoid valve is opened, nitrogen is input from the nitrogen main pipe, and is ejected through the first nitrogen gun after passing through the first air inlet pipe. In this way, the nitrogen flushes out the sludge in the sewage pipe, keeps the sewage pipe unobstructed for a long time, and avoids safety accidents during manual dredging.
