Background

The river station is an important component of an urban water supply and drainage system, and has important functions of carrying urban drainage and guaranteeing urban life and production safety. Urban drainage systems often carry a large amount of floating objects and oil stains to enter river stations, so that the river stations generally need to filter and purify sewage when drainage is carried out for environmental protection.

At present, the pollutant treatment of the river station mainly depends on a manual mode, and when floaters in the river need to be cleaned, workers generally use a net bag to uniformly collect and treat the floaters floating on the river. When the oil stain in the river is required to be cleaned, the worker places the oil suction felt on the river and then moves the oil suction felt to adsorb the oil stain on the river.

In view of the above-mentioned related technologies, the inventor believes that the manner of manually treating the river flotage and the oil stain results in increased labor cost and low treatment efficiency.
