摘要
对目前含PVA(聚乙烯醇)废水处理技术进行了总结,并分析了各种技术的优缺点,对含PVA废水处理技术的发展趋势进行了展望。需重视源头控制,减少污染物排放量;末端治理需要根据实际水质因地制宜,以生化法为主,结合物化法以及深度处理可实现PVA回收以及中水回用,组合工艺处理是主流方向。
Some present reports for the treatments of wastewater containing polyvinyl alcohol(PVA)were summarized. The characteristics of these technologies were discussed, respectively, and the development trend of wastewater containing PVA treatment technology was forecasted. Pollution emissions should be reduced by source control of pollutant discharge. Terminal treatment should be adapted to local conditions according to actual water quality. With biochemical method as the main method, combined with physical and chemical method and advanced treatment, the demand of PVA recovery and middle water reuse would be met. Combination process treatment was the mainstream direction.
