Problems solved by technology

However, its mechanical strength is not enough, especially after the porous carrier part is consumed by beneficial bacteria, the porous carrier is broken and lost, resulting in the reduction of beneficial effects of nitrogen removal and other beneficial bacteria, and it will greatly increase the COD content in water, resulting in secondary pollution

Embodiment 1～15

[0084] According to the raw materials and formulations shown in Table 1, the porous carrier of the present invention was prepared as follows.

[0085] 1. Use a laser microhole puncher to punch holes in the porous layer D containing the non-biodegradable polymer resin B, so that it contains micropores with diameters as shown in Table 1, and the hole density is as shown in Table 1 ;

[0086] 2. Laminate one layer of porous layer C containing non-biodegradable polymer resin A and one layer of porous layer D containing non-biodegradable polymer resin B;

[0087] 3. Wind the laminated multi-layer materials into rolls C and D, with a length of 100mm and a diameter of 60mm;

[0088] 4. Hot-press forming the roll-shaped object under the conditions of 80-120° C. and 0.5-4 MPa to obtain a block-shaped porous carrier with a length of 100 mm×width of 60 mm×thickness of 40 mm.

[0089] By adjusting the temperature, pressure and time of hot pressing, the porosity and interlayer peel stren...

Abstract

The invention provides a porous carrier which contains a biodegradable polymer resin A and a non-biodegradable polymer resin B, wherein the biodegradable polymer resin A and the non-biodegradable polymer resin B are continuous phases. The porous carrier disclosed by the invention can achieve the effects of promoting growth and propagation of beneficial bacteria and maintaining morphological integrity after the biodegradable polymer resin is consumed; after the biodegradable polymer resin is consumed, the non-biodegradable polymer resin in the porous carrier can still provide loading capacity,and since the biodegradable polymer resin is consumed to produce an extra space, the loading capacity of the beneficial bacteria is expanded, beneficial effects of microbes are continuously achieved,and the carrier is easy to recover after being used up.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a porous carrier for water treatment and a preparation method thereof. Background technique [0002] With the release of the National Water Ten Articles, the country has paid more and more attention to the governance and protection of the water ecological environment. At this stage, the pollution of surface water and landscape water in my country is mainly COD and ammonia nitrogen pollution, resulting in serious eutrophication of water bodies. The oxygen content is low, and the water quality is black and odorous. However, there are problems such as low COD removal efficiency and poor nitrification and denitrification efficiency in the traditional sewage biological treatment process, and the treatment effect of domestic sewage and industrial sewage, surface water and landscape water is not good. [0003] The carrier is a solid material that provides a growth en...
