造紙污水處理
造紙廢(fei)水處理(li)一般工(gong)藝(yi)流程設計說(shuo)明：
車間廢水由廠方集中收集到(dao)調節池(chi)，調節水質(zhi)水量(liang)后(hou)提升(sheng)至初沉(chen)池(chi)，除(chu)去廢水中的(de)泥沙、大顆(ke)粒懸浮物及纖(xian)維物質(zhi)。 經(jing)過初沉(chen)池(chi)預處(chu)理后(hou)的(de)出水自流進兩段(duan)生化(hua)處(chu)理工藝(yi)的(de)O1池(chi)。O1池(chi)采用混合(he)活性污泥法，實現(xian)對COD和色度(du)的(de)充分吸附。
O1池(chi)(chi)(chi)(chi)(chi)出(chu)(chu)水(shui)(shui)進(jin)(jin)一沉(chen)池(chi)(chi)(chi)(chi)(chi),活性(xing)(xing)污(wu)泥(ni)回(hui)流(liu)。多(duo)余(yu)活性(xing)(xing)污(wu)泥(ni)進(jin)(jin)污(wu)泥(ni)池(chi)(chi)(chi)(chi)(chi)。一沉(chen)池(chi)(chi)(chi)(chi)(chi)出(chu)(chu)水(shui)(shui)進(jin)(jin)A2池(chi)(chi)(chi)(chi)(chi)。A2池(chi)(chi)(chi)(chi)(chi)為生(sheng)物(wu)膜(mo)法兼氧(yang)池(chi)(chi)(chi)(chi)(chi)做(zuo)兼氧(yang)處理(li)，設潛(qian)水(shui)(shui)攪(jiao)拌機做(zuo)混(hun)合攪(jiao)拌，保(bao)證水(shui)(shui)解效果。A2兼氧(yang)池(chi)(chi)(chi)(chi)(chi)出(chu)(chu)水(shui)(shui)進(jin)(jin)O2好氧(yang)池(chi)(chi)(chi)(chi)(chi)作好氧(yang)處理(li)，采用微(wei)孔曝氣，生(sheng)物(wu)膜(mo)法，實現懸浮型(xing)和附著(zhu)型(xing)活性(xing)(xing)污(wu)泥(ni)多(duo)生(sheng)物(wu)相(xiang)。 O2好氧(yang)池(chi)(chi)(chi)(chi)(chi)后接二沉(chen)池(chi)(chi)(chi)(chi)(chi)，活性(xing)(xing)污(wu)泥(ni)采用污(wu)泥(ni)泵回(hui)流(liu)活性(xing)(xing)污(wu)泥(ni)，方便管理(li)。 為確保(bao)出(chu)(chu)水(shui)(shui)達標，二沉(chen)池(chi)(chi)(chi)(chi)(chi)出(chu)(chu)水(shui)(shui)進(jin)(jin)入終沉(chen)池(chi)(chi)(chi)(chi)(chi)，投加PAC和PAM，進(jin)(jin)一步去除水(shui)(shui)中雜質。終沉(chen)池(chi)(chi)(chi)(chi)(chi)出(chu)(chu)水(shui)(shui)計量外排(pai)。
污(wu)(wu)泥處理：初沉(chen)污(wu)(wu)泥、一沉(chen)池和二沉(chen)池剩(sheng)余(yu)污(wu)(wu)泥進入污(wu)(wu)泥池濃(nong)縮后，由螺桿泵提(ti)升至(zhi)板框壓(ya)(ya)濾(lv)機(ji)脫水。壓(ya)(ya)濾(lv)污(wu)(wu)泥外運填滿或(huo)者(zhe)焚(fen)燒，濾(lv)液回調(diao)節池再處理。
