农药厂废水处理的工艺设计

1、农药厂废水处理的 工艺设计农药废水厂污水处理的工艺设计摘要农药生产中的废水成分复杂、有害、有毒，大多有机磷含量较高，生物降解性较差，生化处理效率比较低。近来，针对农药废水的处理，进行了试验，研究提出物化与生化相结合的治理工艺，使处理后水满足标准排放要求。随着工业的发展，废水中有毒或难降解的有物质成分越来越多，传统的物理和生物处理方法难以达到理想的处理效果，该如何处理废水中有机物，并提高处理效果的成为废水处理行业中的一项重要课题。Fenton （芬顿试剂）氧化法是一种高级氧化技术，既能够作废水的预处理，又能够为废水处理做最终深度处理。其反应的实质是Fe2+和H2O2的链反应催化生成氧化性很强的

2、OH自由基。在传统废水的处理技术和难生物降解的废水处理中，此种方法具有操作简单、反应速度快、费用便宜等优点，已被广泛应用于焦化、印染、农药等废水处理。因此Fenton试剂在废水处理中有着较为广阔的应用前文档仅供参考，不当之处，请联系改正。景，日益受到国内外专家的广泛关注。关键词：农药厂废水，Fenton （芬顿试剂），工艺，设计wastewaterProcess design of pesticide wastewatertreatment plantAbstractThe compositionof thewaste waterof pesticideproduction complex,t
