Problems solved by technology

Although this method plants submerged plants in shallow water areas, it is conducive to the growth of submerged plants and has a high survival rate, but it is only suitable for urban slow-flow rivers. If the storm torrent is large, it is easy to wash away the net bed; There is little exchange between matrix materials and water bodies. On the one hand, the water purification function is affected. On the other hand, the matrix cannot continuously absorb nutrients from river water for submerged plants to absorb, which is also not conducive to the growth of submerged plants.

Embodiment 1

[0059] This embodiment provides a wall-mounted submerged plant water purification module.

[0060] The wall-mounted submerged plant water purification module consists of a filter module 1 ( figure 1 ) and planting module 2 ( figure 2 ), the filter module 1 and the planting module 2 can be disassembled through threads; the filter module consists of a planting module thread bayonet 4, a planting hole 3, a filter medium (nitrogen-absorbing particles 6, phosphorus-accumulating particles 7, growth-promoting particles 8), and a water collection tank 5 Composition, the filter module 1 is a trapezoidal inclined surface upward, the bottom is small and the top is large, the bottom is a water collection tank 5, and the inside is evenly filled with filter media of nitrogen-absorbing particles 6, phosphorus-accumulating particles 7, and growth-promoting particles 8, and the planting holes 3 are evenly distributed in the filter module. up, vertically and obliquely downward, the planting h...

Embodiment 2

[0062] This embodiment provides an application of a hard revetment wall-mounted submerged plant water purification module.

[0063] A certain river in Guangzhou is a semi-enclosed tidal channel. The treated river section is at the end of the river, 1200m long and 15m wide. The water level rises when the tide rises and falls when the tide ebbs. The water depth is 0.8m at the lowest water level and 1.6m at the highest water level. The water level difference is 0.8m. The river channel is a typical U-shaped channel, and the banks on both sides are hard revetments made of masonry. The river sewage interception project and dredging project have been completed. In order to restore the river ecology as soon as possible, 6m submerged plant modules are installed on both sides of the hard revetment at 100m from the end of the river.

[0064] (1) The wall-mounted submerged plant water purification module consists of a filtration module and a planting module.

[0065] (2) The filter modu...

Embodiment 3

[0074] This embodiment provides an application of a hard revetment wall-mounted submerged plant water purification module.

[0075] (1) Make 1.2*0.9*1.2m 3 The glass water tank is mixed with the tail water of the sewage treatment plant and the raw water, and a part of ammonium chloride and phosphate are added to artificially prepare the sewage.

[0076] (2) Make a 0.5*0.3*0.3 filter module with a PVC board, lay a 50-diameter water collection pipe at the bottom, and drill 6mm holes in the water collection pipe every 10cm. The first cover is a multi-space grid plate, and open a diameter every 0.2m 50 planting holes.

[0077] (3) The filter module is filled with 20mm zeolite filter material, 20mm steel slag, and 10mm biological ceramsite, and the volume ratio of the three components is 1:1:1.

[0078] (4) Use a 50-diameter pvc pipe with 6mm-diameter holes around and at the bottom to make a submerged plant planting module, wrap the root system of the bitter grass with a geotexti...

Abstract

The invention relates to the technical field of ecological restoration of water environments and water quality purification, in particular to a wall-mounted submerged plant water purification module and application thereof. The module is composed of a filtering module and a planting module, wherein submerged plants are planted in the planting module, nutritive salt enrichment and adsorption materials are evenly distributed in the filtering module, and a water collecting tank is arranged in the filtering module. The wall-mounted submerged plant water purification module is fixed on a hard revetment of a riverway, a material for enriching and adsorbing nutrient salts such as nitrogen and phosphorus is used as a filtering medium, and continuous and stable growth and reproduction of submerged plants are ensured in a manner of continuously enriching the nutrient salts and allowing plants to absorb by filtering operation, so the ecological system and the landscape of the riverway are maintained and the purification of polluted water is realized.

Description

technical field [0001] The invention relates to the technical field of water environment bioremediation and water quality purification, in particular to a hard revetment wall-mounted submerged plant water purification module and its application. Background technique [0002] Submerged plants are an important primary productivity of the river ecosystem and an important part of the ecosystem. In the river, submerged plants can produce oxygen through photosynthesis, increase dissolved oxygen in water, and prevent water from black and odor; submerged plants secrete flocculants, The suspended matter in the water body is flocculated and deposited to keep the river water clear; the submerged plants inhibit the growth of algae and control the eutrophication of the water body through allelopathy; the submerged plants also provide a good habitat for the spawning of micro-fauna and fish in the water body, which is conducive to creating The complex aquatic ecosystem has great ecological...
