Water treatment apparatus adaptible to natural water environment

A water treatment apparatus, comprising:

• a float configured to float on the surface of a water body;
• a first fluid channel coupled to the float and configured to circulate contaminated water in the water body;
• a first inlet configured to draw the contaminated water into the first fluid channel;
• an outlet configured to allow the contaminated water to exit the first fluid channel;
• a second fluid channel coupled to the float and comprising a filter installed therein, the second fluid channel configured to filter contaminated water in the water body to produce a filtered water flow, wherein the first fluid channel and the second fluid channel are configured to have variable lengths to allow the float to adapt to different water levels;
• a flow control system configured to allow water to flow in a first predetermined angular range while blocking at least a portion of the remaining angular range in at least one of the first inlet and the outlet;
• and
• a fluid transport apparatus configured to draw the contaminated water through the first fluid channel at a first flow rate and the second fluid channel at a second flow rate.
