Abstract: A sewage purification treatment apparatus capable of being assembled in a prefabricated way includes a treatment table, an aeration tank, a filter tank, a water pump, a dosing assembly, a filtering assembly, a cleaning assembly and a washing assembly, the aeration tank and the filter tank are disposed at the top of the treatment table at an interval, an aeration plate is disposed at the bottom end of the inside of the aeration tank. The cleaning assembly works with the filtering assembly to automatically clean the screen in the filtering assembly to prevent impurities from blocking the screen, meanwhile, the screen can be automatically moved out of the filter tank for easy replacement, which is very convenient.

Abstract: The present invention relates to the technical field of water surface waste treatment, and in particular to a water surface floater collecting ship. The technical problems are: picking up floaters with the cooperation of labors consumes manpower and causes disturbance of water surface, which makes the floaters float further away with water waves, and the odor emitted by the collected floating waste will pollute the environment and affect the salvage efficiency. The technical solution is: a water surface floater collecting ship, comprising a hull, a collecting system, etc.; the left part of the hull is connected with the collecting system used for collecting waste.

Abstract: The present invention relates to the field of water surface treatment, and in particular to a cleaning ship for water surface treatment for harvesting water plants. In order to solve the technical problems that the existing cleaning ship cannot adapt to the waters of different depths for harvesting water plants, and a hull has low load utilization rate for the collected water plants and affects the overall working efficiency and the fuel economy of the hull, the present invention provides a cleaning ship for water surface treatment for harvesting water plants, comprising a steel belt conveying mechanism, a driven shaft and the like. The steel belt conveying mechanism drives the driven shaft to rotate.
