以电石法生产PVC树脂工业存在废水排放量大,污染物高等特点,其中乙炔发生器排放工业废水(以Ca(OH)_2为主)占有很大的比例。本文主要介绍了我厂在技术改造的同时主要对乙炔发生器产生的废水进行综合处理利用,节约了大量的水资源,取得了较好的经济、环境和社会效盖。
The production of PVC resin by calcium carbide process has the characteristics of large amount of wastewater discharge and high pollutants. Acetylene generator discharges industrial wastewater (mainly Ca (OH) 2) occupies a large proportion. This paper mainly introduces the technical transformation of our plant mainly to the comprehensive treatment of wastewater generated by the acetylene generator, saving a lot of water resources, and achieved good economic, environmental and social benefits.
