畢業(yè)設(shè)計(jì)_吉林某醫(yī)院污水處理站的設(shè)計(jì)

1、2摘 要本設(shè)計(jì)是關(guān)于吉林某醫(yī)院污水處理站的設(shè)計(jì)。根據(jù)畢業(yè)設(shè)計(jì)的原始資料及設(shè)計(jì)要求對(duì)出水水質(zhì)的要求出水達(dá)到一級(jí)排放標(biāo)準(zhǔn)。一級(jí)處理中,進(jìn)廠原水首先進(jìn)入中格柵,用以去除大塊污染物,以免其對(duì)后續(xù)處理單元或工藝管線造成損害。本設(shè)計(jì)設(shè)置中格柵,中格柵后有污水提升泵提升污水進(jìn)入調(diào)節(jié)池。然后進(jìn)入水解酸化池,用以去除密度較大的無(wú)機(jī)砂粒,提高污泥有機(jī)組分的含率，提高可生化性。以上的污水處理為物理處理階段。本設(shè)計(jì)中，在二級(jí)生化處理部分采用傳統(tǒng)活性污泥法工

2、藝的變形 CASS 工藝, 該工藝可以完成處理水質(zhì)要求。再在接觸池消毒，達(dá)標(biāo)排放。剩余污泥先由重力作用進(jìn)入集泥池再由污泥提升泵提升至重力濃縮池。以降低污泥的含水率，減小污泥體積。泥經(jīng)濃縮后,含水率尚還大,體積仍很大。為了綜合利用和最終處置,需對(duì)污泥進(jìn)行干化和脫水處理。關(guān)鍵詞CASS 工藝 醫(yī)院污水處理 污泥濃縮 消毒AbstractThis is about the design of a hospital sewage trea
