【正文】 strial , the domestic oil refining to chemical and biological wastewater treatment methods, supplemented by some physical methods such as flocculation, precipitation. The process design for refinery effluent water quality, water features, and strive to achieve economy, efficiency, using the traditional, a successful design and operation experience of the activated sludge method, supplemented by physical methods。 本工藝設(shè)計(jì)針對(duì)煉油污水的水質(zhì)、水量的特點(diǎn)，力求做到經(jīng)濟(jì)、高效，采用了傳統(tǒng)的、有成功設(shè)計(jì)、運(yùn)行經(jīng)驗(yàn)的活性污泥法，輔以物理方法；生化部分采用改造的多點(diǎn)進(jìn)水的運(yùn)行方式，工藝流程見如下，處理后出水可達(dá)到國(guó)家石油化工行業(yè)污水排放一級(jí)標(biāo)準(zhǔn)。 受生產(chǎn)工藝和產(chǎn)品的影響，煉油污水的水質(zhì)、水量變化復(fù)雜，有機(jī)污染物濃度不同，是難處理的工業(yè)廢水之一。煉油廠污水處理工藝設(shè)計(jì) 1： 煉油污水是煉油化工行業(yè)生產(chǎn)、運(yùn)行過(guò)程中產(chǎn)生的不可直接利用的污染水，它是國(guó)內(nèi)工業(yè)廢水的重要組成部分 。煉油行業(yè)是環(huán)境污染較為嚴(yán)重的行業(yè)，從原料到產(chǎn)品，從生產(chǎn)到使用，都存在造成環(huán)境污染的因素。目前，國(guó)內(nèi)煉油污水處理手段以生化為主，輔以一些物理方法如絮凝、沉淀等。 格柵 — 調(diào)節(jié)池 — 平流式 隔油池 — 混合反應(yīng)池 — 氣浮池 — 生物接觸氧化池 — 二沉池 — 達(dá)標(biāo)排放 本設(shè)計(jì)說(shuō)明書較全面地?cái)⑹隽嗽O(shè)計(jì)方案的選擇與論證、處理構(gòu)筑物的設(shè)計(jì)計(jì)算、處理站平面布置和高程布置及工程概算等內(nèi)容。 biochemical some more progress with transformation run the water, see the following process, the treated effluent can reach the national level, the petrochemical industry effluent discharge standards.
