    各病房及門診等的排水由排水管網(wǎng)匯入化糞池，經(jīng)過化糞池處理再進(jìn)入后續(xù)水處理構(gòu)筑物。放射科室排放水中有微量放射性物質(zhì)，需要先流入衰變池將放射物質(zhì)衰變后排入格柵井。化糞池出水首先經(jīng)格柵去除較大的懸浮物和漂浮物后自流進(jìn)入調(diào)節(jié)池，調(diào)節(jié)池底部設(shè)有布?xì)夤?，用于攪拌和預(yù)曝氣。經(jīng)調(diào)節(jié)池均化水質(zhì)、調(diào)節(jié)水量后，污水由提升泵提升進(jìn)入酸化水解池，在酸化水解內(nèi)，可使污水均質(zhì)及與沉淀池的回流污泥充分混合，回流活性污泥吸附污水中的有機(jī)物，具有將高分子有機(jī)物分解成小分子易生化有機(jī)物，能更有效地去除污染物;同時(shí)在調(diào)節(jié)池內(nèi)設(shè)置消化區(qū)，在消化區(qū)內(nèi)執(zhí)行NH3-N的硝化和反硝化，可以有效降低水中的NH3-N。污水自流入生物接觸氧化池，進(jìn)行COD、BODs的降解。生物接觸氧化池出水中含有一定量老化脫落的生物膜，這些含有生物膜的污水流入沉淀池，經(jīng)沉淀后清水流入消毒池，消毒脫氯后達(dá)標(biāo)排放。沉淀池污泥部分回流到酸化水解調(diào)節(jié)池，多余污泥排到污泥池濃縮，采用固液分離機(jī)脫水后，定期清理打包外運(yùn)。污泥中脫出的污水回流至調(diào)節(jié)池重新處理。
      The drains from the wards and outpatients are remitted into the septic tank from the drainage pipe network and processed intothe subsequent water treatment structures through the septic tank. There are trace amounts of radioactive material in theradiological departrent, which needs to flow into the decay pool first and disintegrate the radioactive material into the grille well.Septic tank effluent is frst removed by grille to remove larger suspended solias and floats, then flows into the regulating pool
