不能直接排入水體，據(jù)統(tǒng)計(jì)，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(duì)啤酒 污水 進(jìn)行一定的處理。 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池 → 處理水 該處理工藝具有結(jié)構(gòu)緊湊簡潔，運(yùn)行控制靈活，抗沖擊負(fù)荷，污泥 量小等特點(diǎn)。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 。啤酒 污水 處理廠的處理水量為 5000 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)。
