四(si)川成渝釩(fan)(fan)鈦(tai)科技(ji)制品廠，主要(yao)進行(xing)釩(fan)(fan)、鈦(tai)、鉻(ge)(ge)等(deng)金屬品的(de)生產制備，在生產運(yun)(yun)行(xing)過(guo)(guo)程中產生了(le)大(da)量的(de)含釩(fan)(fan)、鉻(ge)(ge)的(de)廢水(shui)(shui)，需經過(guo)(guo)處理后方(fang)可排放或(huo)回用。其廢水(shui)(shui)處理過(guo)(guo)程極為復(fu)雜(za)，且主要(yao)依(yi)靠人(ren)(ren)工(gong)(gong)(gong)(gong)進行(xing)控制反應(ying)，如(ru)人(ren)(ren)工(gong)(gong)(gong)(gong)控制進水(shui)(shui)、人(ren)(ren)工(gong)(gong)(gong)(gong)控制加(jia)藥量、人(ren)(ren)工(gong)(gong)(gong)(gong)調(diao)節(jie)pH等(deng)，由(you)于(yu)(yu)(yu)每組反應(ying)池(chi)需要(yao)多次(ci)進行(xing)pH調(diao)節(jie)并多次(ci)調(diao)節(jie)加(jia)藥量，導致人(ren)(ren)工(gong)(gong)(gong)(gong)勞動強度過(guo)(guo)大(da)。此次(ci)改(gai)造主要(yao)針對硫酸(suan)(suan)、氫氧(yang)化(hua)鈉(na)、焦亞硫酸(suan)(suan)鈉(na)、硫酸(suan)(suan)亞鐵、碳酸(suan)(suan)鈉(na)五類(lei)化(hua)學藥劑進行(xing)自動投(tou)加(jia)，**解決(jue)人(ren)(ren)工(gong)(gong)(gong)(gong)頻繁調(diao)節(jie)加(jia)藥量的(de)弊端，共采用9套(tao)DOSCON智(zhi)能控制系統(tong)，3套(tao)用于(yu)(yu)(yu)預處理單元的(de)除雜(za)，2套(tao)用于(yu)(yu)(yu)**次(ci)除釩(fan)(fan)工(gong)(gong)(gong)(gong)藝(yi)，2套(tao)用于(yu)(yu)(yu)除鉻(ge)(ge)工(gong)(gong)(gong)(gong)藝(yi)，2套(tao)用于(yu)(yu)(yu)第(di)二(er)次(ci)除釩(fan)(fan)工(gong)(gong)(gong)(gong)藝(yi)。該項目于(yu)(yu)(yu)2020年6月完(wan)成調(diao)試，現穩定(ding)運(yun)(yun)行(xing)，出水(shui)(shui)水(shui)(shui)質穩定(ding)達標，降(jiang)低了(le)車間(jian)工(gong)(gong)(gong)(gong)人(ren)(ren)勞動強度。
