Protection Industry Equipment Co.,Ltd,Yixing 214215,China) StipThe Engineering Example of Medium Density Fiberboard Wastewater TreatmentWang songlin1 UASB處理出水達(dá)到《污水綜合排放標(biāo)準(zhǔn)》(89781996)二級(jí)標(biāo)準(zhǔn),可進(jìn)行回用,實(shí)現(xiàn)零排放。關(guān)鍵詞:中密度纖維板廢水 內(nèi)循環(huán) Co.,Ltd,Hefei 230088,China;YixingAbstract: In this paper, it is dissertated that the process of deposition plus flotation plus UASBaerobic plus adsorption to treat medium density fiberboard wastewater is feasible. The COD is taken off over percent in this process, the cost of operation is per cubic meters wastewater. The quality of treated wastewater arrive at the second grade criterion that is disserted in Flotation Inner loop隨著國(guó)家環(huán)境政策的加強(qiáng)及人們環(huán)保意識(shí)的提高,許多中密度纖維板公司開(kāi)始新建或完善自己的廢水處理設(shè)施。木片在加熱軟化后,半纖維素水解成糖類(lèi)、木質(zhì)素和有機(jī)酸,故廢水一般偏酸性。江西某人造板有限公司原有廢水處理采用自然沉淀,有10m16m(H)m的沉淀池6格,沉淀后出水外排。2 處理工藝的確定 SS的去除因廢水中的纖維和木屑等懸浮物濃度較高,如果不及時(shí)去除,不僅會(huì)堵塞管道,并且會(huì)影響后續(xù)處理。再加新型復(fù)合凈水劑,才效果顯著,分層時(shí)間短。根據(jù)其對(duì)氧需求的不同,可分好氧處理和厭氧處理。厭氧處理在無(wú)氧的情況下進(jìn)行,可大大降低運(yùn)行電耗,生成的沼氣能夠回收利用,有一定的經(jīng)濟(jì)效益。好氧利用原有沉淀池,采用接觸氧化工藝。 選用HF800型,2臺(tái),裝在車(chē)間出口處,主要是回收廢水中大顆粒木屑及沙石等。1座,尺寸為5 m5 m(H)m,提升泵選用50WQ17253潛污泵,2臺(tái),1用1備。1座,尺寸為
