25、........................1611.緒論 緒論1.1 項(xiàng)目背景 項(xiàng)目背景近 30 年來(lái),特別是 90 年代以來(lái),隨著我國(guó)經(jīng)濟(jì)的飛速發(fā)展,城鄉(xiāng)人民的生活物質(zhì)水平的不斷提高以及“菜籃子”工程的大力實(shí)施,我國(guó)的畜牧業(yè)向集約化、規(guī)?；?zhuān)業(yè)化方向發(fā)展,由此產(chǎn)生大量的廢水,由于大多未經(jīng)適當(dāng)處理就直接排放,對(duì)環(huán)境以及人體健康造成嚴(yán)重污染,畜牧業(yè)污水正成為與工業(yè)廢水、生活污水相當(dāng)甚至更大的污染源,有些城市畜牧業(yè)污水更是超過(guò)了工業(yè)

26、廢水與生活污水的污染負(fù)荷的總和,其中養(yǎng)豬場(chǎng)廢水的污染負(fù)荷占主要部分。白云區(qū)某畜牧場(chǎng)在為廣州市民“菜籃子”工程添磚加瓦,同時(shí)也產(chǎn)生了大量的糞便污水,使附近水體已經(jīng)土壤受到嚴(yán)重污染,排放出來(lái)的臭氣也嚴(yán)重影響周邊的環(huán)境質(zhì)量。1.2 工程簡(jiǎn)介 工程簡(jiǎn)介為了解決白云區(qū)某畜牧場(chǎng)所帶來(lái)的污染問(wèn)題,同時(shí)變廢為寶,減少污染,建設(shè)污水處理廠處理畜牧場(chǎng)的糞便污水,本設(shè)計(jì)處理量為 350m3 /d。1.3 設(shè)計(jì)進(jìn)出水水質(zhì) 設(shè)計(jì)進(jìn)出水水質(zhì)表 1－1 設(shè)計(jì)進(jìn)出水水
