鑒于啤酒污水自身的特性，啤酒污水不能直接排入水體，據(jù)統(tǒng)計，啤酒廠工業(yè)污水如不經(jīng)處理，每生產(chǎn) 100 噸啤酒所排放出的 BOD 值相當(dāng)于 14000 人生活污水的 BOD 值，懸浮固體 SS 值相當(dāng)于 8000 人生活污水的 SS， 其污染程度是相當(dāng)嚴(yán)重的，所以要對啤酒污水進行一定的處理。 本設(shè)計工藝流程為： 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 池 → 處理水 該處理工藝具有結(jié)構(gòu)緊湊簡潔，運行 控制靈活，抗沖擊負(fù)荷，污泥量小等特點。原污水中各項指標(biāo)為： BOD濃度為 800mg/L ,COD 濃度為 1400mg/L ， SS 濃度為 350mg/L, Ph=6～ 10 。啤酒污水處理廠的處理水量為 7000 dm/3 ,不考慮遠(yuǎn)期發(fā)展。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)。 關(guān)鍵詞 ： 啤酒污水 UASB
