Abstract

The invention discloses a preparation method of a loofah sponge bio-filler for wastewater treatment and belongs to the field of water treatment. Loofah sponge is used as a raw material having good mass transfer performance; the loofah sponge can be combined with a macromolecular material to facilitate quick attachment of microbes; microbial membrane carrier material is subjected to loading modification, and the novel filler is prepared by grafting a photocatalyst to the loofah sponge; the carrier function of the filler is enhanced; the bio-filler having high film-forming speed and high bioactivity is formed. A catalyzing enzyme is extracted from Penicillium simplicissimum; the catalyzing enzyme can be combined with a biological material to provide microbes with mass surface area suitable for rest and beneficial environments, the quantity of microbes in a bioreactor is quickly increased, and wastewater treatment efficiency is improved. The problem is solved that existing bio-fillers areunable to retain bioactivity and provide quick and effective enrichment of microbes due to the absence of affinity with microbes during wastewater treatment.

Description

technical field [0001] The invention belongs to the field of water treatment, and in particular relates to a preparation method of loofah biological filler for sewage treatment. Background technique [0002] Biofiller is a new type of biologically active carrier. It adopts a scientific formula. According to the different properties of sewage, it integrates a variety of trace elements that are conducive to the rapid attachment and growth of microorganisms in polymer materials. It is modified and constructed by special processes. It has the advantages of large surface area, high biological activity and long service life. 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. ...
