处理含汞废水的多节式吸附床
摘要：
本实用新型涉及了一种聚氯乙烯树脂生产中对于含汞废水处理的多节式吸附床，包括一筒体，筒体一端为液体进口、另一端为液体出口，筒体内前端和末端设置有筛板，筒体内部两筛板之间设有吸附剂。本实用新型解决了目前传统的吸附设备处理含汞废水的吸附效率低，从而对环境造成污染的问题。具有结构简单合理、便于操作、占地小、处理过程无二次污染等优点。应用于污水处理中，特别是聚氯乙烯工艺中对含汞废水的深度处理中。
摘要（英）：

The utility model relates to a multi-section adsorption bed for treating mercury-containing waste water during production of polyvinyl chloride resin. The multi-section adsorption bed for treating the mercury-containing waste water comprises a cylinder body, wherein a liquid inlet is formed in one end of the cylinder body; a liquid outlet is formed in the other end of the cylinder body; screen plates are arranged at the front end and the tail end in the cylinder body; and an adsorbent is arranged between the two screen plates in the cylinder body. The multi-section adsorption bed for treating the mercury-containing waste water solves the problem of environmental pollution caused by low adsorption efficiency of the traditional adsorption equipment for treating the mercury-containing waste water at present. The multi-section adsorption bed for treating the mercury-containing waste water has the advantages of simple and reasonable structure, convenience for operation, small occupied area, no secondary pollution in the treatment process and the like. The multi-section adsorption bed for treating the mercury-containing waste water is applied to sewage treatment, in particular advanced treatment on the mercury-containing waste water in a polyvinyl chloride process.
