【正文】 nts of sludge produced by the increasingly plex, such as improper handling, is bound to cause secondary pollution to the natural environment, there are serious environmental safety hidden trouble. In this design, projects required to treat 250 tons/day printing and dyeing sludge. Moisture content of the original sludge， which has been pressed by the frame filter， is approximately 82%. Aiming at the characteristic of dyeing sludge, and in the light of the successful experience of external treatment of dyeing sludge and mature technology of internal treatment of that, we select drying and incineration technology. Such a technology has the advantage of mature, stable, energysaving, small footprint and high efficiency. Basic process is: Stored mud room → Rotary dryer brick machine → Incinerator slag → Ash and other recycled. The main equipment used in the design is 28m Rotary Dryer, AB200 type incinerator, QTY815 block making machine, ppw647 Pulse bag filter, 16m desulfurization tower, LXT5type activated carbon adsorption tower. The total investment is million yuan, the total annual operating cost is 12,643,400 yuan Keywords： dyeing sludge mummification incineration recycle 目錄 1 概述

一套印染污泥烘干系統(tǒng)，用于對進(jìn)廠印染污泥進(jìn)行干化，處理能力為 250 噸 /天（原污泥為經(jīng)過板框壓濾機(jī)壓濾過的含水率約 82%的濕污泥）； (2) 一套制磚設(shè)備，用于將干化后的印染污泥制成磚狀； (3) 一套污泥焚燒及廢氣處理系統(tǒng)，用于處理干化后的印染污泥（干污泥含水率約20%）。該工藝具有 工藝成熟、穩(wěn)定、節(jié)能、占地少、效率高 等優(yōu)點(diǎn)。 本科畢業(yè)設(shè)計(jì)（論文） 250 噸 /天印染污泥干化及焚燒處理 工藝設(shè)計(jì) 學(xué) 院 環(huán)境科學(xué)與工程 專 業(yè) 環(huán)境工程 設(shè)計(jì)總說明 隨著印染行業(yè)蓬勃發(fā)展，我國對印染廢水處理力度在不斷加大，每天處理污水產(chǎn)生相應(yīng)大量污泥 ,污泥量日益增加，產(chǎn)生的污泥的組成成分日益復(fù)雜，如處理不 當(dāng)，必然會對自然環(huán)境造成二次污染，存在比較嚴(yán)重的環(huán)境安全隱患?；竟に嚵鞒虨椋簝δ嗍?→回轉(zhuǎn)烘干機(jī) →制磚機(jī) →焚燒爐 →爐渣、煤灰等 回收。 選擇合適的工藝流程，計(jì)算各處理構(gòu)筑物的主要參數(shù)，選定主要設(shè)備的型號及處理能力，并繪出總平面布置圖、工藝流程圖、空氣管道布置圖、烘干及焚燒設(shè)備剖面圖，對輔助構(gòu)筑物進(jìn)行布 置和設(shè)計(jì)，給出整個(gè)工程的投資概算。 (4) 應(yīng)依據(jù)環(huán)境保護(hù)規(guī)劃、固體廢棄物處理處置規(guī)劃的要求，對污泥進(jìn)行區(qū)域性規(guī)劃和專項(xiàng)規(guī)劃，合理確定污泥處理和處置設(shè)施的布局和設(shè)計(jì)規(guī)模，確保污泥的 2 最終安全處置。所產(chǎn)生的大量污泥通常的處理方法是利用機(jī)械壓濾裝置將污泥的含水率壓濾到 80％以下后外運(yùn)，以填埋、堆放、或傾倒的方式作
