最近幾年，工業發展可以提高一個城市的經濟實力，水質污染問題越來越嚴重，很多工廠生產過程中產生的工業污水都需要使用污水處理設備進行處理。地埋式全自動污水處理設備在處理污水時會采用物理方法來處理污水，使污水得到更好的處理，那么地埋式全自動污水處理設備應用哪些物理方法來處理污水呢，下面海南污水處理小編來為大家(jia)介紹(shao)一下(xia)。
1、篩濾
篩(shai)(shai)濾是預處(chu)理中(zhong)使用最廣(guang)泛的(de)一種(zhong)方法。主要作用是從廢水(shui)(shui)中(zhong)分(fen)(fen)離出(chu)較粗的(de)分(fen)(fen)散性(xing)懸浮固(gu)體(ti)物(wu)。所(suo)用的(de)設(she)備(bei)有格(ge)柵和格(ge)篩(shai)(shai)。格(ge)柵攔截較粗的(de)懸浮固(gu)體(ti)，其作用是保護(hu)水(shui)(shui)泵和后續處(chu)理設(she)備(bei)。食品工業(ye)廢水(shui)(shui)中(zhong)常(chang)用的(de)格(ge)篩(shai)(shai)有固(gu)定篩(shai)(shai)、轉動篩(shai)(shai)和震(zhen)動篩(shai)(shai)等，格(ge)篩(shai)(shai)最常(chang)用的(de)孔徑是10—40目。
2、撇除
廢水(shui)中的油(you)(you)(you)脂(zhi)根據其物理狀(zhuang)態可(ke)分為游離漂(piao)浮(fu)(fu)狀(zhuang)和乳化狀(zhuang)兩大類。通常(chang)隔油(you)(you)(you)池(chi)除去(qu)漂(piao)浮(fu)(fu)狀(zhuang)油(you)(you)(you)脂(zhi)。隔油(you)(you)(you)池(chi)對漂(piao)浮(fu)(fu)狀(zhuang)油(you)(you)(you)脂(zhi)的去(qu)處率(lv)可(ke)達90%以上。如果處理流程中設有(you)調(diao)節池(chi)或沉(chen)(chen)淀池(chi)，則隔油(you)(you)(you)池(chi)可(ke)與調(diao)節池(chi)或初沉(chen)(chen)池(chi)合(he)用(yong)統(tong)(tong)一構(gou)筑物，可(ke)節省(sheng)投資和占地。對小型(xing)處理系(xi)統(tong)(tong)，可(ke)設油(you)(you)(you)水(shui)分離器(qi)撇油(you)(you)(you)。
3、調節
對于水(shui)(shui)(shui)質(zhi)水(shui)(shui)(shui)量變化幅(fu)度大的食品工業廢(fei)水(shui)(shui)(shui)，常設置調(diao)(diao)節(jie)(jie)池(chi)對廢(fei)水(shui)(shui)(shui)的水(shui)(shui)(shui)質(zhi)和(he)水(shui)(shui)(shui)量進行調(diao)(diao)節(jie)(jie)，調(diao)(diao)節(jie)(jie)時間一般為(wei)24h，多為(wei)12h左右(you)。調(diao)(diao)節(jie)(jie)池(chi)容量為(wei)日處理廢(fei)水(shui)(shui)(shui)量的50%。
4、沉淀
一(yi)體(ti)化(hua)污水(shui)處(chu)理(li)設(she)備的(de)(de)(de)沉(chen)(chen)(chen)淀(dian)(dian)(dian)是用(yong)來(lai)除去原廢水(shui)中(zhong)(zhong)(zhong)無機(ji)固(gu)體(ti)物(wu)(wu)(wu)和(he)有(you)(you)機(ji)固(gu)體(ti)物(wu)(wu)(wu)，以及分離(li)生(sheng)(sheng)物(wu)(wu)(wu)處(chu)理(li)工藝中(zhong)(zhong)(zhong)的(de)(de)(de)固(gu)相(xiang)(xiang)和(he)液(ye)相(xiang)(xiang)。用(yong)沉(chen)(chen)(chen)砂(sha)池(chi)(chi)(chi)除去原廢水(shui)中(zhong)(zhong)(zhong)的(de)(de)(de)無機(ji)固(gu)體(ti)物(wu)(wu)(wu);用(yong)初沉(chen)(chen)(chen)池(chi)(chi)(chi)除去原廢水(shui)中(zhong)(zhong)(zhong)的(de)(de)(de)有(you)(you)機(ji)固(gu)體(ti)物(wu)(wu)(wu);用(yong)二(er)沉(chen)(chen)(chen)池(chi)(chi)(chi)分離(li)生(sheng)(sheng)物(wu)(wu)(wu)處(chu)理(li)工藝中(zhong)(zhong)(zhong)的(de)(de)(de)生(sheng)(sheng)物(wu)(wu)(wu)相(xiang)(xiang)和(he)液(ye)相(xiang)(xiang)，沉(chen)(chen)(chen)砂(sha)池(chi)(chi)(chi)一(yi)般設(she)在格柵(zha)和(he)格篩之后(hou)。為了清除廢水(shui)中(zhong)(zhong)(zhong)無機(ji)固(gu)體(ti)物(wu)(wu)(wu)表面(mian)的(de)(de)(de)有(you)(you)機(ji)物(wu)(wu)(wu)，可(ke)采用(yong)曝氣沉(chen)(chen)(chen)砂(sha)池(chi)(chi)(chi)。采用(yong)初沉(chen)(chen)(chen)池(chi)(chi)(chi)可(ke)降(jiang)低后(hou)續工藝的(de)(de)(de)負荷。初沉(chen)(chen)(chen)池(chi)(chi)(chi)除去懸浮固(gu)體(ti)的(de)(de)(de)效(xiao)果與(yu)加工的(de)(de)(de)原料和(he)產品有(you)(you)關。按池(chi)(chi)(chi)中(zhong)(zhong)(zhong)的(de)(de)(de)水(shui)流(liu)方向分為平流(liu)沉(chen)(chen)(chen)淀(dian)(dian)(dian)池(chi)(chi)(chi)、豎流(liu)沉(chen)(chen)(chen)淀(dian)(dian)(dian)池(chi)(chi)(chi)、輻(fu)流(liu)沉(chen)(chen)(chen)淀(dian)(dian)(dian)池(chi)(chi)(chi)。為了提高沉(chen)(chen)(chen)淀(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)(de)沉(chen)(chen)(chen)淀(dian)(dian)(dian)效(xiao)率，可(ke)在沉(chen)(chen)(chen)淀(dian)(dian)(dian)池(chi)(chi)(chi)內設(she)置平行的(de)(de)(de)斜(xie)板或斜(xie)管(guan)而成斜(xie)板(管(guan))沉(chen)(chen)(chen)淀(dian)(dian)(dian)池(chi)(chi)(chi)。
