Problems solved by technology
[0002] In the rural sewage treatment industry, especially in the process of using biofilm method to treat sewage, it is easy to have insufficient carbon source in the influent, resulting in the lack of carbon source for denitrification and denitrification, which seriously affects the removal effect of total nitrogen
In the process of using biofilm to treat sewage, ordinary carriers only provide microbial film-hanging effect, which has a single role

Embodiment Construction
[0037] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "set on" another component, it can be set directly on the other component or there may be an intervening component at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only. The terms used herein in the description of the present invention are for the purpose of describing specific embodiments only, and are not intended to lim...

The invention discloses a slow-release deep denitrification fixed bed and a preparation method thereof. The fixed bed comprises a slow-release bed body which is provided with a mesh, bindings are arranged at the two ends of the slow-release bed, and roughened texture used for enhancing adhesion is arranged on the slow-release bed body. The preparation method of the fixed bed comprises the steps that weaving is conducted to form a slow-release bed body, and a forming machine or a 3D printer is adopted for integrally forming the slow-release bed body. The denitrification fixed bed not only provides biofilm culturing for microorganisms, but also provides a microbial membrane, but also provides a stable release carbon source for the denitrification process; for the fixed bed, after the carbonsource is completely released, a remaining bed body frame can be reused after being crushed, and energy conservation is achieved.
Description
technical field [0001] The invention relates to sewage treatment technology, in particular to a slow-release deep denitrification fixed bed and a preparation method thereof. Background technique [0002] In the rural sewage treatment industry, especially in the process of using biofilm method to treat sewage, it is easy to have insufficient carbon source in the influent, resulting in the lack of carbon source for denitrification and denitrification, which seriously affects the removal effect of total nitrogen. In the process of using biofilm to treat sewage, ordinary carriers only provide microbial film-hanging effect, which has a single role. The commonly used method of replenishing carbon sources is to add methanol, etc., which is not convenient for post-maintenance and management of rural sewage treatment, and is likely to cause secondary pollution. In addition, with the standardization and strictness of the effluent indicators of rural sewage treatment, the requirements...
