污水處理：高懸浮物廢水
來源： 閱讀：2932 更新時間(jian)：2011-11-30 12:11水質特點
懸浮物濃(nong)度高，水(shui)體(ti)的透明性(xing)比較差。
治理思路
廠(chang)區內工業廢水(shui)(shui)(shui)與各車間排水(shui)(shui)(shui)匯(hui)集至集水(shui)(shui)(shui)格柵(zha)渠(qu)，經機(ji)械格柵(zha)機(ji)截留較大(da)漂浮物(wu)后(hou)，進(jin)(jin)(jin)入(ru)吸水(shui)(shui)(shui)井，經提(ti)升(sheng)泵(beng)提(ti)升(sheng)至調節(jie)曝氣池(chi)，調節(jie)水(shui)(shui)(shui)量水(shui)(shui)(shui)質，同(tong)時(shi)采用潛水(shui)(shui)(shui)射流(liu)曝氣機(ji)進(jin)(jin)(jin)行(xing)預曝氣去除(chu)污(wu)(wu)水(shui)(shui)(shui)中(zhong)(zhong)部分有(you)機(ji)物(wu)。曝氣后(hou)的(de)污(wu)(wu)水(shui)(shui)(shui)用泵(beng)送(song)(song)入(ru)斜管(guan)沉(chen)(chen)淀(dian)池(chi)分配井中(zhong)(zhong)，然(ran)后(hou)靠重力(li)流(liu)入(ru)斜管(guan)沉(chen)(chen)淀(dian)池(chi)。水(shui)(shui)(shui)中(zhong)(zhong)含(han)有(you)的(de)大(da)量泥沙快速(su)沉(chen)(chen)淀(dian)，出(chu)水(shui)(shui)(shui)進(jin)(jin)(jin)入(ru)清水(shui)(shui)(shui)池(chi)中(zhong)(zhong)，再(zai)通(tong)過增壓泵(beng)送(song)(song)入(ru)高速(su)過濾(lv)(lv)器(qi)及活性(xing)炭過濾(lv)(lv)器(qi)進(jin)(jin)(jin)行(xing)過濾(lv)(lv)，去除(chu)污(wu)(wu)水(shui)(shui)(shui)中(zhong)(zhong)部分有(you)機(ji)物(wu)和細小懸浮物(wu)。出(chu)水(shui)(shui)(shui)進(jin)(jin)(jin)入(ru)回用水(shui)(shui)(shui)池(chi)中(zhong)(zhong)，用泵(beng)抽至車間回用。斜管(guan)沉(chen)(chen)淀(dian)池(chi)產生的(de)污(wu)(wu)泥截流(liu)進(jin)(jin)(jin)入(ru)泥漿池(chi)，泥漿池(chi)中(zhong)(zhong)含(han)泥水(shui)(shui)(shui)用泵(beng)送(song)(song)入(ru)濃縮池(chi)中(zhong)(zhong)進(jin)(jin)(jin)行(xing)濃縮。濃縮后(hou)的(de)污(wu)(wu)泥送(song)(song)入(ru)廂式壓濾(lv)(lv)機(ji)進(jin)(jin)(jin)行(xing)脫水(shui)(shui)(shui)。
典型治理工藝
1、物化絮(xu)凝沉淀過濾
2、物化絮凝(ning)氣浮(fu)過濾
