五百三十八章 碘回收车间(1 / 1)

相比于浓碘水,稀碘水的回收要困难得多,公司稀碘水的主要来源是过了阴阳树脂后再生而产生的含有有机碘废水,含量一般低于1000ppm,同时还含有碘离子,这部分有机碘跟水的溶解性极好,并且每批数量有上百吨。其它工段的含碘废水是管理问题,留待生产部门通过行政手段解决,而树脂再生废水只能从技术源头解决它。

废水中的有机碘分子量多达到600以上,通过纳滤倒不难浓缩,关键的是盐含量太高了,当纳滤到一定浓度,形成反渗透压后,再进一步纳滤,操作压力会成十倍的增加,同时,纳滤能力将成十倍地降低,王近之想了想,最简单的解决方法就是通过设备升级换代来实现它,分析会上,王近之提议道:“如果能找到对盐有很高透过率的纳滤设备,一切都迎刃而解了。我有个老朋友楼通永,在海洋所多年,从事的就是纳滤,要不,钟部长你与他联系一下?”

一个星期后,钟每文汇报联系结果,对方真的有这样的膜装置,只是膜结构与原来的纳滤膜有很大的不同,是陶瓷膜结构,最大工作压力达到4MPa,另外,没有小试设备,如果要调试的话,只能直接上中试。

“这个设备如能选型成功的话,对企业环保会起到极大的作用,我们一起到采购部商量一下如何租借或采购一台中试设备?”听罢钟每文的联系结果,王近之兴奋地站起身来,欲拉着钟部一起到采购部。

“没用的,我已到采购部联系了,他们说给我们找一找供应商,我们推荐与楼总联系,采购部说是指定供应商,不合规。”钟每文甩了甩手说:“距离春节不到一个月了,如按程序走,春节前肯定试不了设备。要想速度快,只有找吴总协调一条路。可找了吴总,以后联系采购部就困难了,会认为我们借领导的势压他们。”

“考虑这么多干什么?公司利益第一,我们又不是为了个人的私利。”王近之满不在乎地拨通了吴总的手机。

中试设备很快运到,试验结果对高盐有机碘有极好的浓缩作用,出水端的含碘有机物少于3ppm,完全能满足进废水池的要求,只是无机碘离子却被透过去了。

这个简单,无机碘离子被双氧水氧化成单质碘后,可以用活性炭轻松地吸附,只是,每天三百吨的废水,即使活性炭用量只有千分之一,总量也吓人。另外,吸附到活性炭中后怎么给拿出来制成回收碘并且在成本上还能达到不亏本的指标要求呢?活性炭的成本也并不便宜。

经过又一次的内部技术讨论,王近之吩咐顾斌文先对公司含碘活性炭用碱再生后提去碘,再用回收的活性炭试一试。小试结果,同样能够吸住游离碘,整个前期工作在2014年春假前顺利完成,总工办开始正式设计碘回收车间。

看到回收车间进入设计程序,顾斌文忙提前打招呼说:“王总,能不能跟吴总说一下,明年,我到碘回收车间当主任?上次事故后,我几乎每天做恶梦,中试车间主任的压力太大,老婆大人有意见。”

顾斌文的心理,王近之感同身受,可是,回收车间虽然工作压力小,可全是活性炭与含碘废料,生产条件恶劣,另外,不象中试车间一样,可以随时接触到新技术,正是年青有为的时刻,上那里有些浪费,王近之想了想,回复说:“立即就春假了,现在,只是在设计,人事问题起码得年后,不急,春假期间好好地想一想,想通了再说。”
