Sewage suction trucks are a new type of environmental sanitation vehicle designed for collecting, transferring, and cleaning the transportation of sludge and wastewater, thus preventing secondary pollution. These trucks can self-suction and discharge, operate quickly, have a large capacity, and are convenient for transportation. They are suitable for collecting and transporting liquid substances such as feces and sludge. Equipped with a leading domestic sewage suction vacuum pump, these trucks have strong suction power and a long suction range, making them particularly suitable for the extraction, loading, and unloading of sediment in sewers, especially for larger objects like sewage sludge, silt, stones, bricks, etc.
