Abstract

The invention relates to a preparation method of a biological adsorbent for treating basic fuchsin in printing and dyeing wastewater, belongs to a production method of an environment-friendly originalecological green biological adsorbent, and aims to solve the technical problems that an existing adsorbent for treating printing and dyeing wastewater has poor removal effect and is liable to producesecondary pollution. The technical scheme is characterized in that the preparation method of the biological adsorbent for treating basic fuchsin in the printing and dyeing wastewater comprises the following specific steps: 1) washing; 2) drying; 3) soaking in hydrochloric acid; 4) ultrasonic hydrolysis; 5) salting out; 6) soaking in hydrogen peroxide; 7) soaking in ethanol; 8) drying; 9) pulverizing. The preparation method has the advantages that waste resources are reused, adsorption effect is good, secondary pollution is unlikely to produce and the like.

Description

technical field [0001] The invention relates to a preparation method of a biosorbent for treating basic fuchsin in printing and dyeing wastewater, which belongs to an environment-friendly production method of original ecological green biosorbent. Background technique [0002] Printing and dyeing wastewater contains a large amount of dyes, pastes, inorganic salts, oils, acids and bases, and fiber impurities. These impurities pollute the water body mainly in three aspects. First, it reduces the transparency of the water body, making it difficult for plants in the water to perform photosynthesis. Second, it can reduce the amount of dissolved oxygen in the water, making it difficult for aerobic organisms in the water to survive. The last pollutants are highly toxic and can seriously impair the health of organisms that absorb them into their bodies. [0003] As a traditional landscaping tree species in the north, poplar has the characteristics of strong adaptability, strong resi...
