Hydrophilic carrier for microbial biofilm formation

Abstract

The invention discloses a hydrophilic carrier for microbial biofilm formation. The hydrophilic carrier comprises a hollow short tube, and a first concentric ring and a second concentric ring which are sequentially concentrically arranged outside the hollow short tube, wherein the surface of the outermost second concentric ring is toothed; and the microbial filler is composed of the following components in parts by weight: high-density polyethylene, low-density polyethylene, white lime, Dow powder activated carbon, light calcium carbonate, maleic anhydride, dicumyl peroxide, gelatin, chitin, ferroferric oxide magnetic powder and manganese-zinc ferrite. The density of the microbial filler is 0.96-0.98 g / cm<3>. The hydrophilic carrier for microbial biofilm formation prolongs the contact time between microbes and organic matters, so that the organic matters are degraded quickly and thoroughly; and the biological oxidation can restore the surface adsorption capacity of the activated carbon.

Description

technical field [0001] The invention relates to a microbial filler, which belongs to the sewage treatment in the discipline of environmental engineering [0002] technology field. Background technique [0003] 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 an...

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.

[0004] The filler products of the prior art have certain problems in practical application. Due to the small specific surface area, poor hydrophilicity and bio-affinity, there are problems in the speed of film formation, the amount of film formation, and the tightness between the film and the filler. Insufficient; Secondly, due to the low pollution load, the growth of microorganisms is limited and the growth rate is slow, which also makes it difficult to biofilm
