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 discloses suspended microbial packing for wastewater treatment and a preparation method thereof. The suspended microbial packing is prepared from, by weight, 65-75 parts of high density polyethylene, 5-15 parts of slaked lime, 5-20 parts of Dow powdered activated carbon, 6-10 parts of light calcium carbonate, 3-5 parts of maleic anhydride, 1.5-3 parts of gelatin, 1-2 parts of chitin, 0.8-2 parts of ferromagnetic oxide powder and 0.1-0.3 part of manganese zinc ferrite. The suspended microbial packing is high in film formation speed, not prone to fall off, high in treatment efficiency and suitable for treatment of low-concentration organic matter and ammonia nitrogen in sewage and low-concentration organic wastewater. The biological packing has the extremely high hydrophilicity and biocompatibility, has the very high adsorption strength to a biological film and is beneficial for interception and accumulation of biomass on a packing carrier, and therefore the packing can better adapt to wastewater treatment under the low concentration condition.

Description

Technical field [0001] The invention relates to a suspended biological filler, which belongs to sewage treatment in the discipline of environmental engineering [0002] Technical field. Background technique [0003] With the continuous development of cities, the emergence of new industries has accelerated the deterioration of environmental pollution. In particular, the country has stepped up efforts to control industrial pollution and raised sewage discharge standards. It is difficult for the existing treatment technology 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 in accordance with the development needs of the overall environment to meet the increasingly severe environmental requirements. In recent years, biomembrane technology has been used in sewage treatment to solve the requirements of sewage upgrading and compliance, so as to alleviate the water treatme...
