啤酒廠污水處理工藝流程設(shè)計(jì)

摘  要

 啤酒工業(yè)在我國(guó)迅猛發(fā)展的同時(shí)，排出了大量的啤酒污水，給環(huán)境造成了極大的威脅。啤酒污水處理廠的處理水量為5000m3/d ,不考慮遠(yuǎn)期發(fā)展。原污水中各項(xiàng)指標(biāo)為：BOD濃度為800mg/L ,COD濃度為1400mg/L ，SS濃度為350mg/L, pH=6～10 。因該污水BOD值較大,不經(jīng)處理會(huì)對(duì)環(huán)境造成巨大污染，故要求處理后的排放水要嚴(yán)格達(dá)到國(guó)家二級(jí)排放標(biāo)準(zhǔn),即：BOD ≤20mg/L ，COD ≤100 mg/L ，SS ≤70mg/L ，pH=6～9。
 本文分析了啤酒生產(chǎn)中污水產(chǎn)生的環(huán)節(jié)，污染物及主要污染來(lái)源，并從好氧、厭氧生物處理兩方面來(lái)考慮了污水治理工藝，提出了UASB+CASS的組合工藝流程。可將污水COD由1400 mg/L降至50～100 mg/L ，BOD從800mg/L降至20 mg/L以下，SS由350 mg/L降到70 mg/L以下，出水符合標(biāo)準(zhǔn)。
 本設(shè)計(jì)工藝流程為：
 啤酒污水 → 格柵 → 污水提升泵房 → 水力篩 → 調(diào)節(jié)池 → UASB反應(yīng)器 → CASS反應(yīng)池 → 處理水
 該處理工藝具有結(jié)構(gòu)緊湊簡(jiǎn)潔，運(yùn)行控制靈活，抗沖擊負(fù)荷，污泥量小等特點(diǎn)。為啤酒工業(yè)污水處理提供了一條可行途徑。具有顯著的經(jīng)濟(jì)效益、環(huán)境效益和社會(huì)效益。

Sewage Treatment Process Design of Beer Factory

Abstract

 With the rapid development of brewery industry in China, more brewery wastewater is discharged, which endangers enviroment.
 The water which needs to treatment in the beer waste water treatment plant is 5000, regardless of the specified future development. Various target in the raw waste water is: the concentration of BOD is 800 mg/L , the concentration of COD is 1400 mg/L , the concentration of SS is 350 mg/L，and pH is 6～10 . For the beer waste water's BOD is high, it could pollute the environment if drained before treatment, so it request the beer waste water which drained must be strictly treated to the two effluence standard in the country, which is as following: BOD ≤ 20 mg/L , COD ≤ 100 mg/L , SS ≤ 70 mg/L ,pH = 6～9 .
 According to the product scale of beer brewery, the main standard of draining water\natural materials, and so on, the main process technology of the beer waste water disposal station is defined as UASB + CASS .Practice of project indicate, when COD of wastewater reduces from 1400mg/l to 50~100mg/l, BOD reduces from 800mg/l to 20mg/l, SS reduces from 350mg/l to 70mg/l, so that drains out can reaches the Standard.
 The technological process of this design is:
 Beer waste water → Screens → The sewage lift pump house → shuili shai → Regulates tank → Reaction tank of UASB →  Tank of CASS → Treatment water 
 This technology of wastewater treatment has many traits. Such as, well-knit structure, pithy quick control, lasting attacked, less sledge capacity. Practice indicates that the composed craft has reliable function, its investment is little, and its running and management is uncomplicated.
