【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。本流程對處理食品廢水具有處理效果高、操作簡單、運行穩(wěn)定、費用低、污泥產(chǎn)量少的特點。針對該廢水有機污染物濃度較高，易生化降解，懸浮物含量高的特點，經(jīng)過多種方案的比較，本設計最終采用SBR為主體的工藝流程。流程簡述為：首先對污水進行預處理和一級處理，主要有格柵、調(diào)節(jié)池等構筑物，其目的是去除部分懸浮顆粒。并且初步預算表明，該工藝能帶來較好的經(jīng)濟效益和環(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在運行過程中，各階段的運行時間、反應器內(nèi)混合液體積的變化以及運行狀態(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)量與運行功能要求等靈活變化。將微生物細胞物質(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間，許多研究還屬于剛剛起步階段，在基礎理論研究方面存在著很多疑問，在工程應用方面缺乏科學、可靠的設計模式及成熟的運行管理經(jīng)驗，而SBR自身的特點一間歇運行、自動化要求高，又增加了解決問題的難度和應用的局限性。1 項目概況 設計依據(jù)（1）中華人民共和國國家標準《污水綜合指標排放標準》GB897896；（2）國家及地方的有關規(guī)范和法規(guī)；（3）《室外排水設計規(guī)范》； （4）《城鎮(zhèn)污水處理廠附屬建筑和附屬設備設計標準》GJJ31
