Problems solved by technology

Floating beds made of polymer materials are favored by people because of their low cost, strong buoyancy, and stable performance, so they occupy a dominant position in domestic floating bed materials. However, this type of material has fatal flaws in application, such as poor corrosion resistance and easy aging , cannot be used for a long time, mainten

Embodiment 1

[0020] A plant ecological floating bed device for sewage treatment, its plane size is 2.0m×1.5m, the effective water depth is 1.2m, and the effective volume is 3.6 m 3 ; Including water inlet 1, floating bed carrier 2, and water outlet 6 arranged at the bottom of the floating bed, the floating bed carrier 2 is inlaid with planting blue 4, planting basket 4 is planted with plants 3 and filled with waste bricks with a diameter of 1 cm stone or vermiculite5.

[0021] Such as figure 1 As shown, in the constructed floating bed device, the water sample added with 5 mg / L enters the ecological floating bed area through the rotameter 1 at a flow rate of 1.6 L / h, and the number of plants 5 in the planting basket 4 on the floating bed carrier 2 is 12 Dripping Guanyin and 4 calla lilies (each plant height is 30-35cm), and each planting basket has four plants; after seven days of plant ecological floating bed treatment, the floating bed device is discharged from the water outlet 6.

Abstract

The invention discloses a detachable inorganic material ecological floating bed device for sewage treatment. The detachable inorganic material ecological floating bed device comprises a water inlet (1), a floating bed carrier (2) and a water outlet (6), wherein a planting basket (4) is embedded in the floating bed carrier. An ecological floating bed consists of a detachable bed body and the planting basket, plants can be replaced according to the growth conditions so that the purification effect of the ecological floating bed is ensured; a floating bed body is made of clay and foam which are used as inorganic materials so as to have higher microbial affinity and be beneficial to microbial film colonization; the clay and the foam for preparing the floating bed body also have a certain adsorptive power so that the purification capacity of an ecological floating bed system can be further improved; and the planting basket (4) is internally filled with materials (5) such as waste masonry, vermiculite and the like and is used as a carrier for microbial film attachment while functioning for preventing plants from lodging, so that the microbial biomass of the floating bed is increased. In a word, the detachable inorganic material ecological floating bed device is simple and reasonable in structure and ideal in a treating effect of eutrophic water.

Description

technical field [0001] The invention relates to an ecological floating bed device for sewage purification, in particular to a plant ecological floating bed purification device for treating eutrophic sewage. Background technique [0002] The ecological floating bed purification technology with higher plants as the main body has the characteristics of high efficiency, less investment, low operating cost, in-situ repair and pollutant control, etc., and can adapt to various water depths. The management and harvest of plants are also better than artificial wetland systems. Easy, so it is increasingly used to control or restore eutrophic water bodies. At present, the artificial biological floating bed carrier is mainly made of polymer materials, especially polystyrene foam and its modified materials. Floating beds made of polymer materials are favored by people because of their low cost, strong buoyancy, and stable performance, so they occupy a dominant position in domestic float...
