畢業(yè)設計_吉林某醫(yī)院污水處理站的設計

1、2摘 要本設計是關于吉林某醫(yī)院污水處理站的設計。根據(jù)畢業(yè)設計的原始資料及設計要求對出水水質的要求出水達到一級排放標準。一級處理中,進廠原水首先進入中格柵,用以去除大塊污染物,以免其對后續(xù)處理單元或工藝管線造成損害。本設計設置中格柵,中格柵后有污水提升泵提升污水進入調節(jié)池。然后進入水解酸化池,用以去除密度較大的無機砂粒,提高污泥有機組分的含率，提高可生化性。以上的污水處理為物理處理階段。本設計中，在二級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要求。再在接觸池消毒，達標排放。剩余污泥先由重力作用進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,需對污泥進行干化和脫水處理。關鍵詞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
