Description

工业回用水处理方法
技术领域
本发明涉及工业废水处理，特别涉及工业回用水处理方法。
背景技术
在纺织工业中生产各种废水，其中印染废水污染较为严重，其排放量约占工业废水总排放量的1/10，我国每年约有6—7亿吨印染废水排入水环境中，是当前最主要的水体污染源之一，因此印染废水的治理已成为迫切需要解决的问题。
印染废水主要由退浆废水、煮炼废水、漂白废水、丝光废水、染色废水、皂洗废水和印花废水等组成。其特点是成分复杂、色度高、有毒物质多，属于含有一定量有毒物质的有机废水，主要含有残留染料、印染助剂、酸碱调节剂和一些重金属离子,化学需氧量(COD)较高，而生化需氧量(BOD5)相对较低，可生化性差，是当前国内外公认的较难处理的工业废水之一。
印染废水处理的方法大致可以分为生物法、化学法、物理法3大类，但由于印染废水成分复杂，单一处理方法往往不能达到理想的处理效果，在实际应用中大多采用了n种方法的组合来完成对印染废水的彻底处理。
早期印染废水的处理比较常用的为活性污泥法，活性污泥法虽较为成熟，但也存在很多的缺点和不足，如曝气池容积大、占地面积高、基建费用高等，同时对水质、水量变化的适应性较低，运行效果易受水质、水量变化的影响等。
鉴于上述因素，这种污水处理方法逐渐被后来的生物膜法所取代。生物膜法弥补了活性污泥法的很多不足，如它的稳定性好、承受有机负荷和水力负荷冲击的能力强、无污泥膨胀、无回流，对有机物的去除率高，反应器的体积小、污水处理厂占地面积小等优点。但是生物膜法也有其特有的缺陷，如生物滤池中的滤料易堵塞、需周期性反冲洗、同时固定填料以及填料下曝气设备的更换较困难、生物流化床反应器中的载体颗粒只有在流化状态下才能发挥作用、工艺的稳定性较差。
介于以上两种工艺的缺点和不足，移动床生物膜反应器(moving-bed-biofilm-reactor，简称MBBR)应运而生。MBBR法在80年代末就有所介绍并很快在欧洲得到应用，它吸取了传统的活性污泥法和生物接触氧化法两者的优点而成为一种新型、高效的复合工艺处理方法。其核心部分就是以比重接近水的悬浮填料直接投加到曝气池中作为微生物的活性载体，依靠曝气池内的曝气和水流的提升作用而处于流化状态，当微生物附着在载体上，漂浮的载体在反应器内随着混合液的回旋翻转作用而自由移动，从而达到污水处理的目的。
现在经过MBBR处理以后从二沉池出来的印染污水可达到GB4287-2012标准进行外排，但是如果需要达到更高的印染污水回用的目标，其还存在一定的技术难点。
发明内容

步骤3)将2)中的支撑体胚放入烘箱干燥于100℃下干燥12h，将干燥好的支撑体胚放入马弗炉中1100℃-1500℃下烧结，保温1-2h，得到支撑体；
步骤4)将SnCl2·2H20与无水乙醇按照20mg：3ml制成SnCl2溶液，再加入盐酸，密封后搅拌至乳白固体状，再加入适量无水乙醇继续搅拌至得到均匀透明的溶胶；
步骤5)采用浸渍提拉法挂膜，浸渍3-8s，提拉速度为30mm/min，将挂膜后的支撑体于80℃下干燥15min，重复操作10-40次；
步骤6)将挂膜后的支撑体放入马弗炉里热处理，于1100℃-1500℃下烧结得到多孔陶瓷膜。

测验组：杭州某大型印染企业，每日污水总量11000T生化二沉池水样数据测验以及通过实施1-9，对比例1-6后水样数据测验。
从上表看出，实施例7的处理方法效果最好，通过调整烧结温度，改善多孔陶瓷膜的滤过能力。
从上表看出，造孔剂的选择对于过滤能力影响较大，微孔生物床的组成以及比例选择对于其吸附性能有比较大的影响。
