Problems solved by technology

In the further denitrification and phosphorus removal of sewage treatment, additional carbon sources need to be added. These carbon sources can only contact with the microbial groups on the surface, the utilization rate of carbon sources is low, and the existing fillers have poor film-hanging ability, and the biofilm is not easy to fall off.

Abstract

The invention discloses a slow-release filler and a preparation method thereof, which belongs to the technical field of sewage treatment, the sustained-release filler comprises a first nylon skeleton,a second nylon skeleton, rotary biofilm culturing groups, a carbon source and a coating film, the first nylon skeleton is detachably matched with the second nylon skeleton; a spherical skeleton is formed after assembly; the rotary biofilm culturing groups are detachably and rotatably connected into the first nylon skeleton and the second nylon skeleton; wherein the first nylon skeleton, the second nylon skeleton and the rotary biofilm culturing group are respectively provided with a plurality of accommodating holes communicated with the outside, the accommodating holes are filled with carbonsources, and orifices of the accommodating holes are sealed by the coating films, the preparation method of the slow-release filler comprises the following steps: S1, injection molding, S2, filling the carbon sources, S3, curing the carbon sources, and S4, assembling. According to the slow-release filler and the preparation method thereof, the carbon source utilization rate is high, the biofilm culturing capacity is high, and falling of aged biofilms is facilitated.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a slow-release filler and a preparation method. Background technique [0002] The development of many enterprises has been seriously affected by the problems of sewage discharge, treatment and reuse, which has increased the investment cost of enterprise development and slowed down the progress of enterprises. my country's water treatment industry is also accelerating the update of technology according to the development needs of the environment. With the continuous development of cities, emerging industries continue to emerge, and the phenomenon of environmental pollution is also accelerating the deterioration. [0003] There are many sewage treatment methods, the application advantages of biofilm method, and the emergence of membrane technology have reduced the phenomenon of water pollution. Specifically, the carrier for microbial growth and aggregation is set in the ...
