杜笙ADS-600大孔吸附树脂--含酚废水去除苯酚的应用

Phenol. TULSION ADS 600 polymeric adsorbent manufactured by Thermax Ltd is used in several locations in India and abroad also to remove e-mail: phenol from wastewater. Even high concentrations sigui@ mobile ： 018601233390 of phenol (50,000 ppm) in wastewater have been effectively treated. The resin's capacity for phenol increases with increasing phenol concentration. Regeneration of the resin is accomplished in several ways: 1-5% caustic or solvents such as acetone, methanol and formaldehyde. Acetone is frequently used since most phenol plants also have acetone production.
Thermax 公司生产的杜笙 ADS600 聚合物吸附剂用在印度和国外的几个地方，用来去除废水中的苯酚。即使废 水中的苯酚浓度很高 (50,000 ppm)，也能得到有效去除。随着苯酚浓度的增加，树脂去除苯酚的能力也在增
强。树脂再生有以下几种方法： 1-5％ NAOH 或溶剂，如丙酮、甲醇和甲醛。丙酮是比较常用的，因为大多数 苯酚工厂也有生产丙酮。
ADS600：有硬度，含水，多孔，没有官能机的苯乙烯基聚合物，表面积大，达到 600，孔隙度为 5-55％，粒 度大小为 0.3 - 1.2 毫米
� Types of Adsorbent resins: Hydrophobic adsorbent resins – Styrene DVB based and Hydrophilic adsorbent resins – Acrylic based.
PHENOL REMOVAL BY TULSION ADS 600 from THERMAX 使用杜笙 ADS-600去除苯酚
Many of the materials produced by the phenol and aromatic industry are toxic and cannot be discharged without treatment. Current treatment processes usually involve biological degradation or chemical oxidation of the waste organic. These processes suffer from two major drawbacks: they are sensitive to operation conditions and hence thus inconsistent performance and they destroy the product. Since organic concentrations in wastewater tend to be high (1-5%), especially for phenol, recovery of the waste organic can result in substantial cost savings. Polymeric adsorbents are non-functionalized organic polymers, which are capable of removing organic from water. The principle is quite simple. Wastewater is passed through a column containing the polymeric adsorbent. The organic materials are retained on the adsorbent while water and salts pass through. When the resin is fully loaded, the organic are stripped from the resin with solvents or caustic which is a regeneration procedure. The organic material may be concentrated by orders of magnitude in some cases. The following recommendations are those being used at the present time. The regenerant used are not the only ones possible. The choice of regenerant (solvent) usually depends on the availability at the particular location.

由苯酚和芳香物质生产的许多材料是有毒的，未经处理不能排出。目前的处理办法通常是对有机废物进行生 物降解或化学氧化。这些办法有两个主要缺点：对操作环境敏感，性质不稳定，易破坏产品。由于废水中的 有机物浓度往往较高（1-5％），特别是苯酚，有机废物的回收可以节省大量的成本。聚合物吸附剂是一种没 有官能机的有机聚合物，能够去除水中的有机物。原理很简单，废水通过聚合物吸附剂柱时，有机材料就保 留在吸附剂上，水和盐则流过。当树脂吸附饱和时，使用溶剂或烧碱将有机物从树脂上剥离出来，这也是树 脂的再生过程。有机物质可以被浓缩。下面的建议是目前正在使用的方法。再生剂不是唯一可用的办法，再 生剂（溶剂）的选择通常取决于特定位置的可用性。
