Ecological floating bed for purifying organic wastewater

Abstract

The invention discloses an ecological floating bed for purifying organic wastewater. The ecological floating bed comprises a plastic main body frame and a PS extrusion molding floating plate, whereinthe PS extrusion molding floating plate is bundled on the plastic main body frame through a nylon bag, a through hole for placing a flowerpot is formed in the PS extrusion molding floating plate, theflowerpot is placed in the through hole, and is equally divided into an upper part and a lower part, small holes are formed in the lower half part and the upper half part, the diameter of the small hole in the lower part is 1-2 mm, the diameter of the small hole in the upper part is 8-12 mm, the lower part of the flowerpot is filled with a matrix, and aquatic plant or hygrophytes are planted in the matrix. The invention provides the ecological floating bed for purifying organic wastewater, wherein the manufacturing cost is low, aquatic plant or hygrophytes are not prone to death in the growthprocess, the organic wastewater with the large organic pollutant concentration can be effectively treated, the treatment degree is high, and the period is short.

Description

technical field [0001] The technical field of organic wastewater treatment of the present invention particularly relates to an ecological floating bed for purifying organic wastewater. Background technique [0002] Ecological floating bed is also known as biological floating bed, soilless cultivation floating bed, artificial biological floating bed, plant filter bed, etc., using soilless cultivation technology to plant aquatic plants or improved water-loving terrestrial plants with bamboo, plastic foam, etc. On the carrier with large weighing capacity, the pollutants such as nitrogen and phosphorus in the water body are removed through the absorption, adsorption and retention of the plant root system, and finally the pollutants such as nitrogen and phosphorus in the water body are completely removed by moving the plants away from the water body. This technology is currently widely used in river restoration. [0003] Ecological floating bed technology has been widely studied...

AI Technical Summary

Problems solved by technology

In the prior art, the purification of organic wastewater is often carried out by physical and chemical treatment technologies, such as extraction, adsorption, concentration, and ultrasonic degradation. These methods not only have limited processing capacity, but also have high costs. Conventional ecological floating beds are used in the prior art When the technology is used to treat organic wastewater, the planted plants are often prone to death, and the simple use of plants to degrade the pollutants in the organic wastewater has the disadvantages of poor purification effect and long cycle time.
