Embodiment

[0033] This embodiment relates to a multi-stage filter biological floating island, such as figure 1 , 2 As shown, it includes biological floating bed 8, multi-stage filter column system 15 and support rod 5, biological floating bed 8 is connected with multi-stage filter column system 15 by support rod 5, biological floating bed 8 is an open system, and substrate 2 is housed in it. Taken from the bottom mud of Taihu Lake in Wuxi, Jiangsu Province, the thickness of the substrate is 30-50cm. Emergent plants such as cattail 1 and reed 4 are planted on the substrate 2, and plastic nets 3 are set around the biological floating bed, and the aperture is d 1 =3-10mm, use epoxy resin material. The multi-stage filter column system 15 is provided with 27 PVC columnar hollow tubes 9 in total, each hollow tube has a specification of Φ0.4m*2.9m, and the columnar hollow tubes 9 are composed of three sections, such as image 3 As shown, different fillers are set in each section, including ze...

Abstract

A disclosed multistage filtering biological floating island comprises a bio-floating bed, a multistage filtering column system and a support bar; the bio-floating bed is connected with the multistage filtering column system in a water body via the support bar; the bottom of the multistage filtering column system is provided with an anchoring device; and the multistage filtering column system is composed of multiple columnar hollow pipes, the axial direction of the columnar hollow pipes is same to the water flowing direction of the water body, and each of the columnar hollow pipe is filled with a filtering filling material. The bio-floating bed and the multistage filtering column system are effectively combined, the water body space is fully utilized, the biological floating island does not cause any energy consumption and does not generate secondary pollution, the purification effect of water plants, microbes and water-processing matrixes is effectively utilized, water processing cost is substantially reduced, and certain landscape value is provided.

Description

technical field [0001] The invention relates to environmental protection equipment, and more to sewage treatment equipment, in particular to a multi-stage filtering biological floating island. Background technique [0002] The sewage treatment equipment in the prior art has high cost and high operating cost, but the treatment effect cannot meet people's needs. In order to build a harmonious society and protect the environment, how to build a sewage treatment device with low cost and good treatment effect is an urgent problem to be solved by people in this field. [0003] Artificial floating island refers to the construction of artificial floating body on the water body, and then planting plants on the floating body, thus forming a combination of life and non-ecology in a floating island-like structure. The main function of the floating island is to purify the water body, create a new habitat for creatures (fish, birds, zooplankton) and increase the landscape effect. The ar...
