Problems solved by technology

[0004] 1. Existing ecological floating beds use polystyrene foam material, which has the disadvantages of being vulnerable to mechanical damage, short service life, and difficult to recycle.
[0005] 2. After plants are planted on the floating bed of polystyrene foam board, there is no space under the floating bed for direct exchange with air, which affects the natural oxygen enrichment of the water phase and the reproduction of microorganisms

Abstract

The invention provides a plant composite water purification device. The plant composite water purification device is composed of four basic units including a hollowed-out thin-layer support, a buoyancy unit, a plant planting unit and a net bag unit. The hollowed-out thin-layer support is composed of a hollowed-out base support and a base material installed in the hollowed-out base support. Cylindrical floating ball placing holes for adjusting buoyancy, plant planting holes, hanging bolts for hanging net bags and concave-convex bolts for splicing and combining the hollowed-out thin-layer supports are arranged on the hollowed-out base support. The problem that plants are difficult to grow normally when an existing ecological floating bed is applied to rivers and lakes with relatively low nitrogen and phosphorus concentration in water is solved, and the function that the plants absorb nitrogen and phosphorus in a super-accumulated mode is brought into full play; dissolved oxygen in the water body is effectively improved, and condition guarantee is provided for removing nitrogen and phosphorus in the water phase to the maximum extent.

Description

technical field [0001] The invention belongs to the technical field of water body purification, and in particular relates to a plant composite water purification device. Background technique [0002] In terms of water-phase nitrogen and phosphorus purification technologies in rivers and lakes, they can be divided into three categories based on principles: physical methods, chemical methods, and biological / ecological methods. Among them, representative technologies mainly include sediment dredging, mechanical algae removal and ecological water transfer by physical methods; flocculation sedimentation and chemical algae removal by chemical methods; microbial enhanced purification and plant purification by biological / ecological methods. However, many years of research and application results at home and abroad have shown that safe and effective technologies for directly removing nitrogen and phosphorus from rivers and lakes are mainly plant technologies. One of the most represe...
