摘要
反渗透是一种以压力差为推动力,从溶液中分离出溶剂的膜分离操作。反渗透膜是实现反渗透的核心元件,能截留废水中的各种无机离子、胶体物质和大分子溶质,使水质得到净化。本文介绍了反渗透工艺的原理及特点,简述了电镀废水、生活垃圾填埋场渗滤液的特点及几种常用的处理方法,并对反渗透工艺在电镀废水处理与回用、生活垃圾填埋场渗滤液处理中的实际应用效果进行分析。
Reverse osmosis is a membrane separation operation that separates solvent from the solution with pressure difference as the driving force. Reverse osmosis membrane is the core component of reverse osmosis. It can hold all kinds of inorganic ions, colloidal substances and macromolecular solutes in wastewater, so that the water quality can be purified. This paper introduces the principle and characteristics of reverse osmosis technology, the electroplating wastewater, landfill leachate and the characteristics of several commonly used treatment method, and the reverse osmosis process in electroplating wastewater treatment and recycling, landfill leachate treatment in the practical application effect analysis.
