印染废水处理的微藻吸附剂的制备与研究

Preparation and study of microalgae adsorbent for printing and dyeing wastewater treatment

由于印染废水水质复杂,含大量染料、重金属粒子、有机质等,直接排放将造成严重的环境污染,有必要对印染废水进行整治和处理。印染废水处理方法包括物理法、化学法、生物法等。藻生物吸收材料具有价格低廉、吸收容量大、可进行藻生态的资源化使用等优势,使用藻吸附剂处理印染工业废水能达到理想的效果。文章分析了影响藻类吸附性能的因素,并根据目前研究成果的不足,提出了藻类吸收与脱色工艺研究方向的建议。

Due to the complex water quality of printing and dyeing wastewater, it contains a large number of dyes, heavy metal particles, organic matter, etc., direct discharge will cause serious environmental pollution. It is necessary to renovate and treat the printing and dyeing wastewater. The treatment methods of printing and dyeing wastewater include physical method, chemical method and biological method. Algal bio-absorbent materials have the advantages of low price, large absorption capacity and can be used as resources for algal ecology. Using algal adsorbent to treat printing and dyeing industrial wastewater can achieve ideal results. This paper analyzes the factors affecting the adsorption performance of algae, and puts forward some suggestions on the research direction of algae absorption and decoloration technology according to the shortcomings of the current research results.
