Problems solved by technology

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

Embodiment 1～14

[0071] According to the raw materials and formulations thereof shown in Table 1, the microbial carrier of the present invention is prepared according to the following preparation method.

[0072] 1. Use a laser microhole puncher to punch holes in the non-biodegradable polymer resin porous layer B so that it contains micropores with diameters as shown in Table 1, and the hole density is as shown in Table 1;

[0073] 2. Laminate X layer of biodegradable polymer resin porous layer A and Y layer of non-biodegradable polymer resin porous layer B;

[0074] 3. The laminated multilayer film is wound into a roll, so that between two adjacent porous layers A, the maximum value Nm of the number of layers of the porous layer B is as shown in Table 1, with a length of 100 mm and a diameter of 60 mm;

[0075] 4. Hot pressing the roll-shaped object under the conditions of 80-120° C. and 0.5-4 MPa to obtain a block microbial carrier with a length of 100 mm×width of 60 mm×a thickness of 40 mm....

Abstract

The invention discloses a microorganism carrier which comprises more than one biodegradation polymer resin porous layer A and more than one abiotic degradation resin porous layer B. The porous carriercan facilitate growth and reproduction of beneficial bacteria and can also keep shape integrity after biodegradation polymer resin is consumed, abiotic degradation resin in the porous carrier can still provide load capacity after the biodegradation polymer resin is consumed, additional space is generated as the biodegradation polymer resin is consumed, the load amount of the beneficial bacteria is increased, microorganism advantages are continuously achieved, and the microorganism carrier is easily recovered after being used.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a porous composite microbial carrier 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 environment for microor...
