【正文】 brings.Against the characteristics of high concentration of organic matters, easy biodegradation and high levels of suspended solids，the sequencing batch reactor (SBR) process was finally adopted by parison.The process can be summarized as follows:First, pretreatment was carried out to remove suspended particles and the main structures including grille，regulating pool and so on. And then the SBR tank was used as biological treatment and the majority of organic matter were removed here. Sludge generated by the flow was moves away after concentration and dehydration. This flow to processes food waste water to have the processing effect to be high, the simplicity of operator, the movement are stable, the expense is low, sludge output few characteristics. And the preliminary estimate indicated that this craft can bring the good economic efficiency and the environment benefit.Some detailed calculations of constructions including grid， SBR tank，sludge thickener and other structures were pleted in the design. A design instruction booklet and five blueprints including district layout，flow chart, elevation chart，SBR tank and sludge concentration tank were also acplished. Keywords:Food waste water。本流程對(duì)處理食品廢水具有處理效果高、操作簡(jiǎn)單、運(yùn)行穩(wěn)定、費(fèi)用低、污泥產(chǎn)量少的特點(diǎn)。針對(duì)該廢水有機(jī)污染物濃度較高，易生化降解，懸浮物含量高的特點(diǎn)，經(jīng)過多種方案的比較，本設(shè)計(jì)最終采用SBR為主體的工藝流程。流程簡(jiǎn)述為：首先對(duì)污水進(jìn)行預(yù)處理和一級(jí)處理，主要有格柵、調(diào)節(jié)池等構(gòu)筑物，其目的是去除部分懸浮顆粒。并且初步預(yù)算表明，該工藝能帶來較好的經(jīng)濟(jì)效益和環(huán)境效益。 sequencing batch reactor (SBR)。食品工業(yè)原料廣泛，制品種類繁多，排出廢水的水量、水質(zhì)差異很大。 由于SBR在運(yùn)行過程中，各階段的運(yùn)行時(shí)間、反應(yīng)器內(nèi)混合液體積的變化以及運(yùn)行狀態(tài)等都可以根據(jù)具體污水的性質(zhì)、出水水質(zhì)、出水質(zhì)量與運(yùn)行功能要求等靈活變化。將微生物細(xì)胞物質(zhì)與水沉淀分離，廢水即得到處理。但SBR工藝尚處于發(fā)展完善階段，SBR的興起不過十幾年的時(shí)間，許多研究還屬于剛剛起步階段，在基礎(chǔ)理論研究方面存在著很多疑問，在工程應(yīng)用方面缺乏科學(xué)、可靠的設(shè)計(jì)模式及成熟的運(yùn)行管理經(jīng)驗(yàn)，而SBR自身的特點(diǎn)一間歇運(yùn)行、自動(dòng)化要求高，又增加了解決問題的難度和應(yīng)用的局限性。1 項(xiàng)目概況 設(shè)計(jì)依據(jù)（1）中華人民共和國(guó)國(guó)家標(biāo)準(zhǔn)《污水綜合指標(biāo)排放標(biāo)準(zhǔn)》GB897896；（2）國(guó)家及地方的有關(guān)規(guī)范和法規(guī)；（3）《室外排水設(shè)計(jì)規(guī)范》； （4）《城鎮(zhèn)污水處理廠附屬建筑和附屬設(shè)備設(shè)計(jì)標(biāo)準(zhǔn)》GJJ31
