摘　　要：煤化工企业中高含盐废水当中氨氮化合物一直是污水处理的难题。传统的吹脱法、沉淀法、微生物处理法都存在很多问题,无法进行完全处理。VESP振动膜技术是一种被广泛应用于煤化工中矿物油分离,废水治理等方面的处理技术,其优点在于处理量高、膜通量高、占地面积小、耗能低。本文选取了一种具有较高含盐量的煤化工企业废水作为研究对象,探讨了用VESP振动膜法处理高含盐废水的可行性。通过试验,考察了VESP振动膜处理污水中氨氮的性能。试验结果表明:pH值为7.5,温度为20℃,振荡频率为30 Hz,压力为2500 kPa时,氨氮的脱除效果最佳。为以后的实验和实际生产提供了详细的数据。Ammonia and nitrogen compounds in high salinity wastewater from coal chemical enterprises have always been a difficult problem in wastewater treatment.There are many problems in the traditional methods of blowing off,precipitation and microbial treatment,which cannot be completely treated.VESP vibration membrane technology is widely used in the coal chemical separation of mineral oil,wastewater treatment and other aspects of the treatment technology,its advantages are high treatment capacity,high membrane flux,small footprint,low energy consumption.The high salinity wastewater from a coal chemical enterprise was selected as the research object to explore the possibility of VESP vibration membrane as a treatment method for ammonia nitrogen compounds.The removal effect of VESP vibration film on ammonia nitrogen pollutants in wastewater was studied.The experiment shows that ammonia nitrogen extraction is best when the pH value is about 7.5,the temperature is 20℃,the vibration frequency and the pressure of the device are 30 Hz and 2500 kPa.Detailed data are provided for future experiments and actual production.
