Description

technical field [0001] The invention relates to a preparation method of a biological adsorbent for treating basic fuchsin in printing and dyeing wastewater, which belongs to a production method of an environment-friendly original ecological green biological adsorbent. Background technique [0002] Printing and dyeing wastewater contains a large amount of dyes, pulp, inorganic salts, oils, acid and alkali and fiber impurities. These impurities pollute the water body in three aspects. First, reducing the transparency of the water body makes it difficult for plants to perform photosynthesis in the water. Second, it reduces the amount of dissolved oxygen in the water, making it difficult for aerobic organisms to survive in the water. The final contaminant is highly toxic and can seriously damage the health of the organisms that absorb it into the body. [0003] As a traditional landscaping tree species in the north, poplar has the characteristics of strong adaptability, strong ...
