摘要

焦化废水成分复杂，是一种典型的含高浓度化学需氧量（COD）、难生物降解的工业废水。目前大多数焦化厂的废水经处理后COD仍很难达标，因此亟需开发一种新型绿色高效且廉价吸附剂。采用共沉淀法制备了一系列改性无定形硅铝吸附剂并用于焦化废水中COD去除。通过比较原始与经晾干、焙烧和铵交换改性处理的吸附剂（ASA-1、ASA-2、ASA-3和ASA-4）的COD去除率，探究了不同改性方法

对吸附剂理化性质和吸附性能的影响机制。结果表明，与其他3种吸附剂相比，ASA-3的COD去除效果最佳，当其硅铝比（原子数之比）为4.50、焙烧温度为750 ℃和投加量为50 g/L时，在25 ℃下搅拌3 h，COD去除率可达62.40%。ASA-3的高吸附性能得益于其更优的织构性质（比表面积为271.0 m

/g）和丰富的酸性位点。ASA-4在酸性位点增加时吸附性能却较弱（COD去除率为32.54%），因为铵交换破坏了其结构（比表面积仅53.8 m

/g）。通过拟一级、拟二级和颗粒内扩散模型拟合改性吸附剂在不同吸附时间下的吸附量，并对吸附机理进行了探究，发现吸附过程符合拟二阶模型，受液膜扩散、化学吸附和颗粒内扩散机制控制。

Abstract

Coking wastewater

characterized by its complex composition

is a typical industrial wastewater with a high concentration of chemical oxygen demand (COD)

which is resistant to biodegradation. Currently

most coking plants struggle to achieve compliance standards for COD even after wastewater treatment

thus there is an urgent need to develop a new type of green

efficient and low-cost adsorbent. A series of modified amorphous silica-alumina adsorbents were synthesized via the co-precipitation method and applied for COD removal in coking wastewater. By comparing the COD removal rates of the original adsorbent and modified adsorbents through drying

calcination

and ammonium exchange (ASA-1

ASA-2

ASA-3

and ASA-4)

the influence mechanisms of different modification methods on the physicochemical properties and adsorption performances of the adsorbents were explored. The results show that ASA-3 exhibits the best COD removal efficiency among the four adsorbents. At a ratio of silicon atoms number to aluminium atoms number of 4.50

calcination temperature of 750 ℃

and dosage of 50 g/L

COD removal reaches 62.40% after stirring for 3 h at 25 ℃. The excellent adsorption performance of ASA-3 is attributed to its enhanced textural properties (specific surface area of 271.0 m

/g) and abundant acidic sites. Conversely

although the acidic sites of ASA-4 increase

its adsorption performance is relatively poor (with a COD removal rate of only 32.54%). This is because the ammonium exchange process disrupt its structure (a specific surface area of merely 53.8 m

/g). Adsorption capacities of modifie

d adsorbents at different adsorption time were fitted using pseudo-first-order

pseudo-second-order

and intra-particle diffusion models. The adsorption mechanism was investigated

revealing that the adsorption process conforms to the pseudo-second-order model and is governed by liquid film diffusion

chemical adsorption

and intra-particle diffusion mechanisms.
