Embodiment 1

[0025] Its components and content are (by weight percentage): the content of the high-density polyethylene is 70%, the content of the bamboo fiber is 5%, the content of the magnetic powder is 20%, and the rest is pyrite powder.

[0026] Using sulfur autotrophic denitrification technology to achieve simultaneous nitrogen and phosphorus removal. Its technical principle is that sulfur autotrophic denitrifying microorganisms (Thiobacillus denitrificans) use sulfur as an electron donor to reduce nitrate ions in water to nitrogen, and at the same time, ferric ions produced combine with phosphate ions in water to form iron phosphate precipitation. . The bamboo fiber in the filler has good hydrophilicity and adsorption, which can increase the film-hanging rate of Thiobacillus denitrification on the surface of the filler. The weak magnetic field generated by the magnetic material can promote the growth and metabolism of biological cells, and induce the synthesis of enzymes and enzymes....

Abstract

The invention discloses a sulfur-containing bamboo fiber magnetic suspension filler, and belongs to the field of sewage treatment. The sulfur-containing bamboo fiber magnetic suspension filler is characterized by comprising a high-density polyethylene base material, a bamboo fiber, pyritic powder and a magnetic material. Due to high hydrophilicity and adsorbability of the bamboo fiber, the film formation rate of thiobacillus denitrificans on the surface of the filler is increased; a weak magnetic field is formed by the magnetic material, so that the growth of the thiobacillus denitrificans ispromoted, and the autotrophic denitrification rate is increased. The sulfur-containing bamboo fiber magnetic suspension filler can deeply treat sewage, and can remove nitrogen and phosphorus at the same time, thereby solving the problem of high operation cost caused by heterotrophic denitrification of an external carbon source.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sulfur-loaded bamboo fiber magnetic suspension filler. Background technique [0002] The concentration of nitrogen and phosphorus in the effluent of the existing sewage treatment plant cannot meet the requirements of the first-class A standard. Many sewage treatment plants use external organic carbon sources to enhance biological denitrification and phosphorus removal, but a large number of experiments and engineering practice results show that it is difficult to ensure the simultaneous stability of nitrogen and phosphorus in urban sewage treatment plants by traditional upgrading and transformation centered on biological system transformation To reach the standard, it is still necessary to consider supplementary chemical phosphorus removal to achieve stable phosphorus compliance, and adopt coagulation, sedimentation, filtration and other processes to reduce suspended solids, che...
