Composite ecological algae-inhibiting suspended bed

The utility model relates to a composite ecological algal inhibition suspended bed which comprises a suspended plant planting bed, a substrate improving bed, a suspended bed position adjusting device and a filter screen, and the suspended plant planting bed and the substrate improving bed are arranged up and down and jointly covered by the filter screen. The suspended bed position adjusting device is respectively connected with the suspended plant planting bed and the substrate improving bed; submerged plants are planted on the suspended plant planting bed. The device has the beneficial effects that a water body is purified through the suspended plant planting bed, black and odorous bottom mud is subjected to in-situ remediation through the substrate improving bed, so that the soil character of the substrate is improved, the water body is comprehensively and efficiently remedied by fully utilizing the space of the water body, and the device is ecological, safe and low in cost and has relatively high environme
