Heavy water pollution processing apparatus

The utility model relates to a sewage treatment device and benthophyte planting device, especially a heavy water pollution processing apparatus. Including outstanding floating frame, guide bar, the regulation floater that is used for placing sewage treatment device, hang the floating frame cover and establish on the guide bar, adjust the floater and be connected through nonelastic connecting piece with outstanding floating frame. The principle of floater is utilized to above -mentioned structure, coordinates the nonelastic outstanding floating frame of connecting piece control, when using, inserts the aquatic with the guide bar, prevents to hang floating frame and moves, and the floater has two kinds of usages, adjusts certain buoyancy to make outstanding floating frame suspension in a certain position of normal water for one kind, takes place water -level fluctuation or weight and changes, and buoyancy is adjusted to the floater, makes it still suspend and do not take place the position change, also has an usage, and the buoyancy of adjusting the floater exactly is greater than the weight of hanging floating frame, through no flexible connectors, no matter is that water level or weight change, the certain position of the surface of water of can both keeping at a distance.
