Problems solved by technology

[0003] There are currently a series of corresponding measures for the above problems, but these measures generally have regional applicability, and it is difficult to apply them to tropical coastal saltwater lakes
At present, the main problems faced by tropical coastal saltwater lakes are: (1) The equipment is easily corroded; (2) Typhoons are often attacked, which poses a threat to the stability of the equipment
(3) The salinity of lake water changes greatly, and it is difficult for purifying organisms to adapt to this environment, which in turn affects their purifying effect
The present invention aims to solve the problems encountered by tropical coastal lakes: its special physical and chemical indicators and environmental climate factors - high temperature, high humidity and high salinity general biological purification devices cannot meet such hydrological conditions and climate environment

Embodiment 1

[0026] This embodiment is basically as attached figure 1 Shown: The spirulina sewage purification device for tropical coastal eutrophic saltwater lakes, including the main shaft 1 and the frame 2 made of POLYSULFONE (PSU) materials, the frame 2 is a hollow frame 2, and the main shaft 1 is located at the center of the circular frame 2 The frame 2 includes an outer frame 201 away from the main shaft 1 and an inner frame 202 close to the main shaft 1. A slot is welded between the outer frame 201 and the inner frame 202, and a floating ball 3 is inserted in the slot.

[0027] as attached figure 2 As shown, the main shaft 1 passes through the sliding column 4, and twelve support rods 5 are connected between the sliding column 4 and the outer frame 201. The angle between any two support rods 5 is 30 degrees, and the angle between the support rods 5 Both sides are provided with grid buckles for fixing the first breeding grid 6 . Between the poles 5, there is a first culture grid 6...

Embodiment 2

[0035] as attached image 3 As shown, the difference between the present embodiment and the first embodiment is that a connection port 301 is opened at the part where the floating ball 3 emerges from the slot, and a connection rod 302 is fixedly connected to the connection port 301 .

[0036] The implementation process of this technical solution is as follows, as attached Figure 4 As shown, the intersection point of the circle is where the floating ball 3 is located. In typhoon weather, the floating ball 3 can connect multiple frames 2 through the connecting rod 302. When multiple frames 2 are connected together, the wind and wave resistance of the device will be enhanced.

Embodiment 3

[0038] as attached Figure 5 And attached Figure 6 As shown, the difference between the present embodiment and the second embodiment is that the main shaft 1 passes through a rotating ring 8, the rotating ring 8 is located below the sliding column 4, and the outer surface of the rotating ring 8 is provided with fan blades 9 from top to bottom. And the outer tooth portion, the inner frame 202 is provided with the inner tooth portion towards the sliding column 4, the disc 10 with straight teeth is engaged between the inner tooth portion and the outer tooth portion, and the second breeding grid is arranged in the disc 10 .

[0039] The implementation process of the present embodiment is as follows: because the sliding column 4 is located above the rotating ring 8, the water purification plants in the first cultivation grid 6 between the poles 5 will cover the fan blades 9, so the fan blades 9 are not affected by the external wind force. disturbed and rotated. When encountering...

Abstract

The invention discloses a spirulina sewage purification device used for tropical coastal eutrophic saltwater lakes and relates to the technical field of water pollution control. The device comprises amain shaft, a frame surrounds the circumferential direction of the main shaft, the frame includes an outer frame body and an inner frame body, a clamp groove is connected between the outer frame bodyand the inner frame body, a floating ball is clamped in the clamp groove, at least two support rods are connected between the outer frame body and the main shaft, and a first aquaculture grid used for cultivating water purification plants is arranged between the adjacent support rods. The eutrophication problem of the tropical coastal saltwater lakes is mainly solved through the water body bioremediation technology. The device has a simple structure, is light, and has good wind wave resistance and corrosion resistance. Domesticated spirulina is selected as the water purification plants withhigh water purification efficiency and the economic benefits are large.

Description

technical field [0001] The invention belongs to the technical field of water body pollution control, and in particular relates to a spirulina sewage purification device used in tropical coastal eutrophic salt water lakes. Background technique [0002] In recent years, water pollution has attracted more and more attention. Water pollution in lakes, reservoirs, and urban rivers is mainly caused by eutrophication of water bodies. Due to the poor fluidity and low self-purification ability of lakes, reservoirs, and urban rivers, eutrophication is relatively serious. Due to the discharge of excess nutrients (mainly nitrogen, phosphorus, etc.) into natural water bodies, algae and other plankton multiply rapidly. cause deterioration of water quality. [0003] There are currently a series of corresponding measures for the above problems, but these measures generally have regional applicability and are difficult to apply to tropical coastal saltwater lakes. At present, the main pro...
