丙烯腈废水处理技术的研究

Study on the treatment technology of acrylonitrile wastewater

丙烯腈废水处理的难点在于丙烯腈的毒性和高COD负荷,因此生化前的预处理十分重要。文章采用实际废水进行实验,对预处理工艺进行筛选和优化研究。结果表明:采用NaClO氧化,投加量为5%~6%,有较好的处理效果。出水可进入生化处理。

The difficulty in the treatment of acrylonitrile wastewater is the toxicity of acrylonitrile and high COD load.Therefore,pretreatment before biochemistry is very important.The article uses the actual wastewater to conduct experiments,screening and optimization research on the pretreatment process.The results show that:NaClO oxidation,the dosage is 5-6%,and has a good treatment effect.The effluent can enter biochemical treatment.
