This invention relates to a deep-well pressurized coupled open-type enclosure ecological algae control system and its maintenance method. Enclosures are set up upstream and downstream of areas where dense algae residue has formed a sedimentation zone in the water body. These two enclosures, together with the riverbed, form an open ecological zone. The algae control well is located at the front end of the upstream enclosure. Blue-green algae enters the well from the inlet of the inner cylinder, loses its buoyancy after being subjected to hydrostatic pressure, and then a flow-propelling device pumps the algae-laden water through the return channel between the outer and inner cylinders into the water body of the ecological zone. The blue-green algae disperses in the water, and filter-feeding fish and benthic organisms filter-feed the algae residue throughout the ecological zone, resulting in high algae residue treatment efficiency. A trolley device moves a driving net from a first position to a second position on the track. The driving net, with its shape conforming to the water body cross-section and utilizing the fish's upstream swimming habits, drives adult fish from downstream to upstream. An air-floating net cage inflates and floats, enclosing the driving net and the fish within a second net body, saving costs and achieving high automated capture efficiency.
