高浓度有机废水生物蒸发处理技术及展望

生物蒸发技术主要是利用高浓度有机废水自身所包含的有机物微生物好氧降解产生的热量为驱动力,使废水中的水分汽化,并配合适宜的通风,使蒸汽进入气相主体而散发,从而实现有机物和水分的同步去除。该过程主要受曝气量、堆体初始含水率及有机负荷影响。该技术在不需要外加热源的条件下,既可以实现水分有效蒸发去除,又对废水中的污染物质进行了有效降解,是一项经济、节能、环保的新技术。

Novel bio-evaporation process for the treatment of highly concentrated organic wastewater and its prospect

Bio-evaporation technology mainly makes use of the heat produced from aerobic biodegradation of organic matter that consisted in organic wastewater itself as driving force,so as to make the moisture content of water vaporize.Coordinating with appropriate ventilation can make the steam enter into gas phase and give out,so as to realize synchronous removal of organic matter and moisture content.This process is mainly affected by aeration capacity,initial water containing rate of the pile and organic loading.When the technology is under a condition that does not need any external heat sources,it can either realize the effective evaporation removal of the moisture content,or realize the effective degradation of the polluted materials in wastewater,being a kind of economic,energy-saving and environment-friendly technology.
