一、前言进入二十一世纪以来,中国聚氯乙烯生产迅猛发展,至2008年,产能已突破1400万吨/年,产生了超过4000万吨的聚氯乙烯母液废水,该废水水量大、温度高、浊度高(主要是PVC颗粒)、有机物降解难,其处理回收利用成为困扰氯碱行业多年的环保难题,造成了很大的环境 I. INTRODUCTION Since entering the 21st century, the PVC production in China has been developing rapidly. By 2008, its production capacity has exceeded 14 million tons / year, producing more than 40 million tons of PVC wastewater. The wastewater has large amount of water and temperature High, high turbidity (mainly PVC particles), the degradation of organic matter is difficult to deal with the recycling of chlor-alkali industry has become a problem for many years of environmental problems, resulting in a great environment
