2、管網(wǎng)按遠(yuǎn)期規(guī)模設(shè)計(jì)，污水管網(wǎng)由3條干管、1條主干管組成；雨水管網(wǎng)分為5個(gè)流域，就近排入水體。污水處理廠選址在規(guī)劃區(qū)西南方向，布射河下游河畔。設(shè)計(jì)進(jìn)水水質(zhì)為：BOD5=233mgL，CODcr=340mgL，SS=234mgL，NH3N=30mgL，TP=3mgL。通過工藝選擇、方案對比，確定污水處理流程如下：城市污水—中格柵—提升泵站—細(xì)格柵—旋流沉砂池—A2O生物池—高密度沉淀池—普通快濾池—紫外消毒渠—巴氏計(jì)量槽—出水。出水水質(zhì)達(dá)到

3、一級標(biāo)準(zhǔn)A標(biāo)準(zhǔn)（GB189182002），即：BOD5≤10mgL，CODcr≤50mgL，SS≤10mgL，NH3N≤5mgL，TP≤0.5mgL，尾水排至布射河。污泥處理流程如下：二沉池出泥—污泥泵房—污泥濃縮池—貯泥池—污泥消化池—脫水車間。污水處理廠分兩期建設(shè)，近期規(guī)模2.0萬m3d，遠(yuǎn)期規(guī)模3.0萬m3d。整個(gè)排水工程總投資24195.56萬元，污水處理廠的年運(yùn)行費(fèi)用為1082萬元，單位運(yùn)行成本為0.99元m3。關(guān)鍵詞：排水管
