Abstract

The invention provides an environmentally friendly material for papermaking wastewater treatment, which is made of the following components in parts by weight: 50-60 parts of thiophene fluorene polyamide, 15-25 parts of ionized polypyrrole tube surface modification Ti-W-O; Thiophene fluorene polyamide is prepared by polycondensation reaction of 9,9-bis(4-aminophenyl)fluorene, 2,5-thiophene dicarboxylic acid and furyl triazine. The invention also discloses a preparation method of the environmental protection material for papermaking wastewater treatment, comprising the following steps: mixing thiophene fluorene polyamide and ionized polypyrrole tube surface modified Ti-W-O in proportion to obtain the mixture, and then mixing The mixed material is put into a twin-screw extruder for blending and extruding, and then granulated to obtain an environmentally friendly material for papermaking wastewater treatment. The environmental protection material for papermaking wastewater treatment prepared by the invention has the advantages of low cost, high wastewater treatment efficiency, good effect, less consumption, convenient recycling and no secondary pollution.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an environment-friendly material for papermaking wastewater treatment and a preparation method thereof. Background technique [0002] In recent years, with the continuous development of industry, the problem of water pollution has become increasingly serious, which is threatening human health. With the gradual strengthening of people's awareness of environmental protection and the formulation of various relevant laws and regulations, wastewater treatment has become a major problem that has to be faced in the process of global industrialization. Papermaking wastewater is one of many wastewaters, and its discharge ranks first among all kinds of industrial discharges in my country. Papermaking wastewater mainly includes cooking waste liquor (also known as black liquor), intermediate water produced in the washing and bleaching process, and white water produced in the paper...
