Problems solved by technology
At present, the commonly used fillers in China are fixed fillers such as honeycomb fillers, soft fillers, semi-soft fillers, and composite fillers. However, these fillers often encounter problems such as clogging, agglomeration, and hardening during use, which affects the biological treatment effect.
And the above-mentioned fillers need to be installed on the auxiliary bracket, which causes many inconveniences such as filler installation and replacement.

Abstract
The invention provides a novel suspended biological filler and its production method. The production method comprise the following steps: carrying out compound modification so as to form a polyolefin plastic which is used as a skeleton; allowing the skeleton to form a cylindrical shape and forming reinforcing ribs on the inner side of the skeleton; forming a surface porous material as a coating layer; and coating the outer side of the skeleton with the coating layer. The novel suspended biological filler is easy to install and not prone to agglomeration and blockage.
Description
technical field [0001] The invention relates to the field of wastewater treatment, in particular to a novel suspended biological filler and a production method. Background technique [0002] With the continuous development of cities, the emergence of emerging industries has accelerated the deterioration of environmental pollution. In particular, the state has stepped up efforts to control industrial pollution and raised sewage discharge standards. It is difficult for existing treatment technologies to meet the requirements of the new standards. Therefore, my country's water treatment industry is also accelerating the development and research of new technologies according to the development needs of the environment to meet the increasingly severe environmental requirements. In recent years, biofilm technology has been used in sewage treatment to meet the requirements of sewage upgrading, so as to alleviate the pressure of water treatment of enterprises and the pollution of s...
