論文污水處理系統(tǒng)的設計與調(diào)試

1、山東工商學院信電學院電氣工程及其自動化專業(yè)2009屆畢業(yè)論文1污水處理系統(tǒng)的設計與調(diào)試摘要：污水處理系統(tǒng)的效益巨大，但運行成本高，經(jīng)濟效益差，為了讓污水處理技術有效的實現(xiàn)使系統(tǒng)能夠連續(xù)穩(wěn)定運行，保證出水水質(zhì)達標，將自動控制技術應用與污水處理中，提高污水處理的自動化水平已成為污水處理中的關鍵問題。本文以污水處理廠的控制系統(tǒng)為研究背景，結(jié)合污水處理工藝，探討PLC及其網(wǎng)絡在污水處理廠中的應用，并充分考慮在線檢測儀表在控制系統(tǒng)中的作用。文中主
