Abstract

The invention discloses a constructed wetland renewable matrix block structure, and a making and using method thereof. The matrix block structure comprises a matrix block fixing member and a matrix block, the artificial wetland matrix block fixing member comprises a base plate (1), a fixing end (2), a lifting rod (3) and a top pulling head (4), the matrix block (8) is composed of a plurality of matrix sheets (5), every matrix sheet (5) is composed of a poplar catkin cotton layer (6) and a matrix (7), and the matrix blocks (8) are compressed and then are fixed on the matrix block fixing member. After constructed wetland is blocked, the matrix structure can be taken out through a suspension hook, the matrix block (8) is replaced by a new matrix block (8), and the matrix structure is put back. The replaced matrix block (8) contains organic matters, can be used in anaerobic fermentation to prepare biogas or hydrogen, residues can be used as a fuel, and combustion ash can be used to prepare manure. The method can realize the rapid replacement of the constructed wetland matrix and the complete recycling of the matrix.

Description

technical field

[0001] The invention relates to the technical field of wetland ecology of environmental protection engineering, in particular to a structure of a constructed wetland renewable substrate block and a method for using it. Background technique

[0002] Constructed wetlands have a large amount of sewage treatment, high efficiency, no secondary pollution, and are widely used. However, at present, the substrates of constructed wetlands mostly use natural substrates, and the treatment after clogging is difficult and costly. Therefore, develop renewable substrates, make substrate blocks, and replace them at clogged locations to ensure that the continuous operation of wetlands will not be affected.

[0003] At present, there is no matrix block for constructed wetlands. After the constructed wetlands are blocked, the entire system will be paralyzed. Replacement of the matrix requires the entire piece of excavation, which takes a long construction period and consumes a l...

Examples

example 1

[0020] Example 1: Park Constructed Wetland

[0021] Such as figure 1 , figure 2 and image 3 As shown, the constructed wetland renewable matrix block structure includes two parts: the matrix block fixing component and the matrix block. The constructed wetland matrix block fixing component includes a bottom plate 1, a fixed end 2, an upper lifting rod 3 and an upper lifting head 4. The matrix block 8 consists of Composed of two matrix sheets 5, the matrix sheet 5 is composed of a poplar cotton layer 6 and a matrix 7, and the matrix block 8 is compressed and fixed on the matrix block fixing member.

[0022] Bottom plate 1 is made of concrete permeable board with a width of 350 mm, a length of 500 mm, and a thickness of 20 mm; the upper lifting rod 3 is made of plastic with a diameter of 10 mm; upper lifting head 4 is made of wood, with a length of 50 mm, a width of 20 It is 10mm, fixed on the lifting rod 3.

[0023] After the matrix block 8 is manufactured, it is compressed...

example 2

[0028] Example 2: Courtyard Constructed Wetland

[0029] Such as figure 1 , figure 2 and image 3 As shown, the artificial wetland renewable matrix block structure is prepared for courtyard-style artificial wetlands. The bottom plate 1 is made of concrete permeable board with a width of 200mm, a length of 300mm, and a thickness of 10mm; the lifting rod 3 is made of plastic and has a diameter of 5mm; The upper lifting head 4 is made of plastic, with a length of 30 mm, a width of 10 mm, and a thickness of 5 mm, and is fixed on the upper lifting rod 3 .

[0030] After the matrix block 8 is made, it is compressed with a pressure of 50kPa. After compression, the center is opened, and the hole diameter is larger than the diameter of the lifting rod 3 by 2mm. The length and width of the prepared matrix block 8 are smaller than the bottom plate by 2mm.

[0031] Poplar wadding layer 6 is woven from poplar wadding with a layer thickness of 1 mm. The matrix sheet 5 is composed of 3 l...
