2、m3/d。所選用的污水處理工藝為:廢水從進(jìn)水到格柵和篩網(wǎng),再到調(diào)節(jié)沉淀池,由污水泵進(jìn)入集水井,然后進(jìn)入升流式厭氧污泥床(UASB),再進(jìn)入SBR反應(yīng)池,最后排入水體。污泥處理流程為:從升流式厭氧污泥床(UASB)和SBR反應(yīng)池排出的污泥進(jìn)入污泥井,通過潛污泵送入濃縮池,然后進(jìn)入脫水機(jī)房,最后外運(yùn)處置。廢水處理廠處理后的出水要達(dá)到國家污水綜合排放標(biāo)準(zhǔn)(GB8978—1996)中的二級排放標(biāo)準(zhǔn)。本設(shè)計(jì)所選擇的UASB+SBR工藝完全能達(dá)到所期望的處理效果。關(guān)鍵詞:升流式厭氧污泥床(UASB);SBR;造紙廢水。-I
