論文污水處理系統(tǒng)的設(shè)計(jì)與調(diào)試

1、山東工商學(xué)院信電學(xué)院電氣工程及其自動(dòng)化專(zhuān)業(yè)2009屆畢業(yè)論文1污水處理系統(tǒng)的設(shè)計(jì)與調(diào)試摘要：污水處理系統(tǒng)的效益巨大，但運(yùn)行成本高，經(jīng)濟(jì)效益差，為了讓污水處理技術(shù)有效的實(shí)現(xiàn)使系統(tǒng)能夠連續(xù)穩(wěn)定運(yùn)行，保證出水水質(zhì)達(dá)標(biāo)，將自動(dòng)控制技術(shù)應(yīng)用與污水處理中，提高污水處理的自動(dòng)化水平已成為污水處理中的關(guān)鍵問(wèn)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(luò)在污水處理廠中的應(yīng)用，并充分考慮在線檢測(cè)儀表在控制系統(tǒng)中的作用。文中主
