对RO进行(xing)反渗透浓(nong)缩，是(shi)钢铁企业实现(xian)(xian)废水(shui)(shui)零排放的关键，只(zhi)有对RO进行(xing)有效处理(li)，才能(neng)真正实现(xian)(xian)零排放。RO浓(nong)水(shui)(shui)因其高(gao)(gao)(gao)盐、高(gao)(gao)(gao)COD、高(gao)(gao)(gao)硬度等(deng)特(te)性，常被归入(ru)高(gao)(gao)(gao)难度废水(shui)(shui)一类。Neterfo极限(xian)分离系统是(shi)专为高(gao)(gao)(gao)溶解固体、高(gao)(gao)(gao)硬质、开(kai)发了一种(zhong)高(gao)(gao)(gao)COD废水(shui)(shui)中高(gao)(gao)(gao)浓(nong)度物(wu)质膜深度处理(li)系统，不(bu)仅降低了废水(shui)(shui)排放，而且实现(xian)(xian)了废水(shui)(shui)资源的循环利用，并且可以节约(yue)排放成本。

　　钢(gang)铁(tie)(tie)业既(ji)是(shi)用(yong)(yong)水(shui)(shui)大(da)(da)户，又是(shi)污染大(da)(da)户。钢(gang)铁(tie)(tie)厂用(yong)(yong)水(shui)(shui)的(de)(de)(de)(de)供求矛盾(dun)十分突出，今后要实现(xian)(xian)钢(gang)铁(tie)(tie)工(gong)业的(de)(de)(de)(de)可(ke)持续发展，必须实现(xian)(xian)生产用(yong)(yong)水(shui)(shui)厂的(de)(de)(de)(de)水(shui)(shui)资源循环利(li)用(yong)(yong)，即(ji)利(li)用(yong)(yong)废水(shui)(shui)处(chu)理回用(yong)(yong)及近零排放技术实现(xian)(xian)废水(shui)(shui)的(de)(de)(de)(de)循环利(li)用(yong)(yong)，是(shi)钢(gang)铁(tie)(tie)工(gong)业不(bu)断追求的(de)(de)(de)(de)目标。

　　钢铁厂(chang)RO浓水进(jin)入(ru)微米级精(jing)滤系(xi)(xi)(xi)统(tong)(tong)，经初步处理(li)后达到反渗透膜(mo)分(fen)离系(xi)(xi)(xi)统(tong)(tong)对(dui)进(jin)水的要(yao)求。再次进(jin)入(ru)Neterfo极限(xian)分(fen)离系(xi)(xi)(xi)统(tong)(tong)，Neterfo系(xi)(xi)(xi)列之一(yi)适合中、低、高(gao)TDS进(jin)水，它能(neng)平衡系(xi)(xi)(xi)统(tong)(tong)的回收率和出水质量，出水达到用水量的要(yao)求，实现钢铁企业废(fei)水零排放。

　　Neterfo极限分离(li)系(xi)(xi)统(tong)的模块化设(she)计(ji)，能满足要求的高度匹配。本实用(yong)(yong)新型采用(yong)(yong)错(cuo)流PON抗污(wu)染技术(shu)，POM宽流道高架桥旁路技术(shu)等，达到了较高的回(hui)收利用(yong)(yong)率和低能耗(hao)。打破传(chuan)统(tong)工艺瓶颈(jing)，综合回(hui)收率达到90%以上。传(chuan)统(tong)回(hui)用(yong)(yong)系(xi)(xi)统(tong)排(pai)放水量只(zhi)有1/5，大(da)大(da)地降低了环境保护(hu)负担。该系(xi)(xi)统(tong)短程设(she)计(ji)，模块化配置，节点控制简(jian)单。
