【正文】 濾池處理工藝簡(jiǎn)介： 由于我國(guó)小城鎮(zhèn)居住點(diǎn)分散，污水源分布點(diǎn)多量少，城鎮(zhèn)級(jí)污水廠的規(guī)模多低于 10000噸 /日。 工藝流程： 圖 11 曝氣生物濾池工藝流程 應(yīng)用范圍：中、小型城市污水處理廠 。在一般水處理過程中，均需用到排泥機(jī)械，排泥機(jī)械是保證水處理廠各種沉淀 構(gòu)筑物正常運(yùn)轉(zhuǎn)的關(guān)鍵設(shè)備。沉淀池通過重力沉淀的原理，去除污水中的泥等懸浮物。不同類廢水的處理廢水不一樣的。固體廢物設(shè)備的年產(chǎn)值占全國(guó)環(huán)保產(chǎn)品總產(chǎn)值的比率約 5%；噪聲與振動(dòng)控制設(shè)備的年產(chǎn)值占全國(guó)環(huán)保產(chǎn)品產(chǎn)值的 %；環(huán)境監(jiān)測(cè)儀器年產(chǎn)值約占 %。城市污水再生利用工作，單靠政府行為，沒有市場(chǎng) 推動(dòng)，必然動(dòng)力不足；單靠市場(chǎng)推動(dòng)，沒徐州工程學(xué)院畢業(yè)設(shè)計(jì) (論文 ) 2 有政府引導(dǎo)，也必然難見成效。從這個(gè)意義來說，我國(guó)的城市污水再生利用，目前還處于發(fā)展起步階段。s request, through contrasts several sets of plans the good and bad points, finally has settled this paper design proposal, this design selects half straddle type peripheral transmission, including the horizontal truss, the revolving truss, the plate girder, the central revolving supporting, to blow the arm and the scraper, the wheel and the aisle, shaft coupling isostructuralism, this plan good design set has blown the putty equipment, this machinery has the structure to be simple, the weight is light, saves the operating cost, the maintenance management to be convenient, the consumed power is small, the work efficiency is high, the security is high, the transmission is steady, ease of operation construction cost low status merit.
