Compound deep purification ecological floating bed with external carbon source and purification treatment method thereof

Abstract

The invention relates to a compound deep purification ecological floating bed with an external carbon source and a purification treatment method thereof. The purification ecological floating bed structurally comprises a floating bed frame, an A bamboo raft, a geogrid, a polystyrene board, a plant, a nylon cable tie, a spherical framework, a gauze element, a starch / PHB (Poly-beta-hydroxybutyrate) blend, a fixing rod, a cuboid-shaped gabion and a B bamboo draft, wherein the A bamboo draft and the B bamboo draft are fixed onto the frame through iron wires; the plant 5 is fixed onto the polystyrene board; the polystyrene board is wrapped with the geogrid; the geogrid is fixed onto the frame through the nylon cable tie; a suspension rope is tied to the lower part of the geogrid; the starch / PHB blend is wrapped with the gauze element; the starch / PHB wrapped with the gauze element is placed into the framework; the framework is fixed onto the fixing rod; and the cuboid-shaped gabion is fixed onto the frame through iron wires. The compound deep purification ecological floating bed with the external carbon source has the advantages that the materials are easily available, cost is low, purification efficiency is high, effects are obvious, and management is convenient.

Description

technical field [0001] The invention relates to an ecological floating bed combined with an external carbon source and compound deep purification and a purification treatment method thereof, belonging to the field of sewage treatment. Background technique [0002] Ecological floating bed is a method of sewage treatment that emerged in the 1970s. Using the principle of soilless cultivation technology, the terrestrial plants are cultivated and then introduced into the water body for planting. With polymer materials as the carrier and matrix, modern agronomy and ecological engineering measures are adopted. Comprehensive and integrated water surface soilless planting technology. Through the absorption of essential plant elements such as N and P during the growth process of plants, the adsorption of plant roots and the hydrolysis and metabolism of biofilm on the surface, organic matter and nutrients are decomposed, and finally in the form of harvested plants, N Nutrients such as...
