改造碳黑废水处理设施使废水循环使用

介绍碳黑废水处理工艺流程的技术改造及其技术要点。着重阐述了关键设备斜管沉淀池的运行原理、运行结果及其在整个流程改造过程中所起的作用。改造后的工艺流程特点是斜管沉淀效率高，出水水质好，副产品碳黑质优销路好，劳动强度低，废水可循环使用，设备占地少，运行费用低，总体效益好。改造后实现了全厂生产用水闭路循环，取得了可观的经济、环境、社会效益。废水循环利用在技术上是可行的，经济上有收益，实现了废水及固体废物的资源化。

Reform of Carbon Black Waste Water Disposal Facilities for Recycle

This paper refers to technological transformation of process flowtreating carbon black waste water and its technical essentials.It expounds emphaticallythe separation principle and results of the key equipment inclined tube settling tand andits action in the whole reform process.The characteristics of the process flow modifiedare high settling efficiency,good water quality,high quality of byproduct carbon blackhaving a good sale,reduction of operating labour intensity,recycling of waste water,e-quipment taking up less land,low operation cost and good overall benefit. After reforma-tion it brings about the water volume used over the whole plant in the form of a closedcycle,thus gaining remarkable economic,environmental and social benefits.It holds thatthe waste water recycle after technological transformation is a practicable technologygetting economic profits and making waste water and solid waste converted into re-source
