污水深度處理系統-填料生物反應器【填(tian)料生物反應器(qi)系統簡介】 生(sheng)(sheng)(sheng)物填料(liao)起源于日本(ben),經過(guo)(guo)二十多(duo)年(nian)的技術進步已(yi)經發展(zhan)為一(yi)整套成熟(shu)的生(sheng)(sheng)(sheng)化水(shui)(shui)處(chu)理技術。在(zai)(zai)(zai)填料(liao)中(zhong)(zhong)(zhong)存在(zai)(zai)(zai)填料(liao)球(qiu)之間的大(da)空(kong)隙、填料(liao)球(qiu)介(jie)質(zhi)塊之間的小空(kong)隙和(he)填料(liao)球(qiu)介(jie)質(zhi)塊內部的微(wei)空(kong)隙,在(zai)(zai)(zai)大(da)空(kong)隙中(zhong)(zhong)(zhong)流(liu)體流(liu)速快,氣(qi)水(shui)(shui)交換充分,適(shi)合好氧(yang)微(wei)生(sheng)(sheng)(sheng)物生(sheng)(sheng)(sheng)長;在(zai)(zai)(zai)介(jie)質(zhi)塊中(zhong)(zhong)(zhong)的微(wei)孔中(zhong)(zhong)(zhong)氣(qi)水(shui)(shui)傳(chuan)質(zhi)只能(neng)通過(guo)(guo)擴散(san)過(guo)(guo)程實(shi)現(xian)(xian),適(shi)合厭氧(yang)微(wei)生(sheng)(sheng)(sheng)物生(sheng)(sheng)(sheng)長。污(wu)染物和(he)活性污(wu)泥在(zai)(zai)(zai)水(shui)(shui)流(liu)帶動(dong)下在(zai)(zai)(zai)大(da)孔好氧(yang)區、小孔缺氧(yang)區和(he)微(wei)孔厭氧(yang)區中(zhong)(zhong)(zhong)反(fan)復交換,是(shi)“就(jiu)地(di)硝化、反(fan)硝化”成為可能(neng),也使得(de)污(wu)泥的就(jiu)地(di)生(sheng)(sheng)(sheng)化降(jiang)解(jie)得(de)以(yi)實(shi)現(xian)(xian)。 【填料生物反(fan)應器技術優勢】 (1)該(gai)技術(shu)可(ke)以將有(you)效(xiao)微(wei)(wei)生(sheng)物(wu)固(gu)定在介(jie)質塊表(biao)面,使微(wei)(wei)生(sheng)物(wu)的(de)停留時間大(da)大(da)延長,因此更(geng)能有(you)效(xiao)的(de)篩選和馴化微(wei)(wei)生(sheng)物(wu); (2)該(gai)技術(shu)存在(zai)多種溶解氧環(huan)境(jing)和多種微生物(wu)可以附著(zhu)的表面,使得同步(bu)硝化(hua)反硝化(hua)成為可能; (3)該技術中微生(sheng)物種群比活性污泥(ni)(ni)法豐富(fu)的多(duo),因而在(zai)活性污泥(ni)(ni)中不可(ke)生(sheng)化降(jiang)解的有(you)機物在(zai)MCM反應器中卻可(ke)以被生(sheng)化降(jiang)解; (4)由于(yu)該技術反(fan)應(ying)器存在豐富的微生(sheng)(sheng)(sheng)物(wu)(wu)(wu)生(sheng)(sheng)(sheng)長環(huan)境,只要某種(zhong)微生(sheng)(sheng)(sheng)物(wu)(wu)(wu)有“食(shi)物(wu)(wu)(wu)”這種(zhong)微生(sheng)(sheng)(sheng)物(wu)(wu)(wu)就可能在該技術中(zhong)(zhong)繁殖(zhi)。因此,在該技術體系中(zhong)(zhong)剩余的生(sheng)(sheng)(sheng)物(wu)(wu)(wu)污(wu)泥(ni)在氣/水流動(dong)帶動(dong)下將會與那些以污(wu)泥(ni)為“食(shi)物(wu)(wu)(wu)”的微生(sheng)(sheng)(sheng)物(wu)(wu)(wu)接觸反(fan)應(ying),*終(zhong)剩余的生(sheng)(sheng)(sheng)物(wu)(wu)(wu)污(wu)泥(ni)被(bei)降解(jie)。 【填料生物反(fan)應器(qi)應用領域(yu)】 生物反應器以其負荷高(gao)、抗沖擊能力強、處(chu)理效果好、占地(di)面(mian)積小、操作管理簡(jian)單、剩余(yu)污(wu)(wu)泥少等優點,可以廣(guang)泛應用于市政(zheng)污(wu)(wu)水(shui)(shui)及(ji)工業廢水(shui)(shui)領(ling)域。 |
