浠水縣南城區(qū)污水處理工程設(shè)計研究 摘要： 浠水縣城區(qū)在 浠水縣中部，坐落在浠水河畔，是全縣政治、經(jīng)濟、文化教育的中心。 浠水河自東向西穿越城區(qū)，并將城區(qū)分為南北兩片 。 浠水縣城區(qū)的排水現(xiàn)狀是老城區(qū)為雨污合流制排水系統(tǒng)，新建南城區(qū)排水系統(tǒng)不完善，只有少量的污水管，雨水基本是隨地形漫流進入水體。 由于排水系統(tǒng)不完善，大部分地區(qū)尚未設(shè)排水管道，導致地面積水，且污水未經(jīng)處理排入浠水河，造成水體污染，影響環(huán)境。 浠水縣位于中國南方。 現(xiàn)階段浠水縣 南 城區(qū) 排放污水中以生活污水為主， 工業(yè)廢水 占一定比例，約為 51%， 幾乎 水中各項 污染物 指標均低于全國平均值。 根據(jù) 這中情況 ， 本工程擬采用 的工藝如下：一級處理采用細格柵和鐘式沉砂池，二級處理采用厭氧池和氧化溝處理。處理過程中產(chǎn)生的污泥，經(jīng)過濃縮脫水后外運填埋。 該工藝的特點是抗沖擊負荷能力強，同時具有 脫氮除磷效果。
