农药废水预处理技术及生化处理效果研究

农药废水处理难度大,根据生产工艺、原料和产品的不同,产生的废水特点亦不同。本文以实际农药厂废水为研究对象,对高氨氮废水、含氟废水、高盐废水和生化性差的四种典型废水提出有针对性预处理方法,预处理后再混合其他废水进行生化处理,达到纳管排放标准,本处理思路以期为其他类似生产企业的废水治理提供参考。

Pesticide wastewater is difficult to treat. According to different production process and raw materials, the characteristics of wastewater are different. In this paper, the pre-treatment of four typical wastewater including high ammonia wastewater, fluorine-containing wastewater, high salt wastewater and poor biochemical wastewater was studied. Finally, The typical wastewater after pre-treatment mixed with the other wastewater for biochemical treatment. The results showed that the final efflent satisifed the discharge standard. This paper is able to provide reference for the other similiar manufacturing enterprise in wastewater treatment area.
