農藥廠廢水處理的工藝設計

1、農藥廠廢水處理的 工藝設計農藥廢水廠污水處理的工藝設計摘要農藥生產中的廢水成分復雜、有害、有毒，大多有機磷含量較高，生物降解性較差，生化處理效率比較低。近來，針對農藥廢水的處理，進行了試驗，研究提出物化與生化相結合的治理工藝，使處理后水滿足標準排放要求。隨著工業(yè)的發(fā)展，廢水中有毒或難降解的有物質成分越來越多，傳統(tǒng)的物理和生物處理方法難以達到理想的處理效果，該如何處理廢水中有機物，并提高處理效果的成為廢水處理行業(yè)中的一項重要課題。Fenton （芬頓試劑）氧化法是一種高級氧化技術，既能夠作廢水的預處理，又能夠為廢水處理做最終深度處理。其反應的實質是Fe2+和H2O2的鏈反應催化生成氧化性很強的

2、OH自由基。在傳統(tǒng)廢水的處理技術和難生物降解的廢水處理中，此種方法具有操作簡單、反應速度快、費用便宜等優(yōu)點，已被廣泛應用于焦化、印染、農藥等廢水處理。因此Fenton試劑在廢水處理中有著較為廣闊的應用前文檔僅供參考，不當之處，請聯(lián)系改正。景，日益受到國內外專家的廣泛關注。關鍵詞：農藥廠廢水，F(xiàn)enton （芬頓試劑），工藝，設計wastewaterProcess design of pesticide wastewatertreatment plantAbstractThe compositionof thewaste waterof pesticideproduction complex,t
