DDNP废水处理现状及展望

The Status and Prospects of DDNP Wastewater Treatment

二硝基重氮酚生产过程中排出的废水来自还原、重氮化和洗涤,产生量较大,成分复杂、色度高、毒性大。现有DDNP废水的治理方法因工艺复杂、投资大等原因处理效果不佳,难以达到排放标准而不宜采用。文章将对DDNP废水处理现状进行分析以及结合目前的新思想、新技术对DDNP废水处理方法进行探讨,以及为DDNP废水处理方法的进一步研究提供理论依据。

Diazo dinitro phenol production process wastewater from the reduction, diazotization and washing, resulting in larger, complex composition, heavy color and high toxicity. Existing wastewater treatment method for DDNP is complex, high investment; other treatment factors are ineffective, difficult to achieve emission standards and should not be used. This paper will give an overview of DDNP wastewater treatment as well as the status quo of the present new ideas, new technologies for DDNP wastewater treatment. So have a discussion with a new view for DDNP wastewater treatment and provide a theoretical basis for further research.
