Abstract

The invention discloses a preparation method of biological packing for wastewater treatment and belongs to the field of water treatment. According to the preparation method, 10-undecen-1-ol and propylene are taken as raw materials, polar monomers trimethylaluminium and triisobutyl aluminium, methylaluminoxane and 2,6-di-tert-butyl-4-methylphenol are added and taken as promoters, ferrocene is takenas a main catalyst, a polymerization reaction is performed, oxygen atoms in enol are shielded by larger substituent groups on alkyl aluminium, catalyst poisoning caused by the fact that lone pair electrons on the oxygen atoms coordinate with an active center is prevented, protected undecylenyl alcohol monomers are copolymerized with propylene to obtain a polymer, hydroxyl is introduced into the polymer, the polymer has better hydrophilic performance and better binding property with wastewater in wastewater treatment, and water treatment efficiency is improved. The problem that the treatment effect is affected due to the fact that current packing is poor in affinity when bound with microorganisms and is prone to balling is solved.

Description

technical field [0001] The invention belongs to the field of water treatment, and in particular relates to a preparation method of biological filler for waste water treatment. Background technique [0002] The types and quantities of impurities contained in different water sources are different. Even in the same water source, the composition and content of impurities are constantly changing with space and time. Generally speaking, when the source water contains many types of pollutants and complex properties, but the concentration is low, it is usually called slightly polluted source water. The pollutants in slightly polluted source water are mainly organic pollutants, some of which are natural organic compounds, such as products formed by the decomposition of animals and plants in water (such as humic acid, etc.), and the other part are synthetic organic substances such as pesticides. [0003] Biofiller is a new type of biologically active carrier. It adopts a scientific f...
