高锰酸钾预氧化与微滤膜联用去除微污染物的研究

膜技术是水处理技术之一,其中MF膜可截留水中绝大部分悬浮物、胶体和细菌,是可靠的除浊和消毒工艺,但对水中有机物的去除率却不高,需作适当的预处理。预氧化技术能有效去除水中的有机污染物,提高出水水质。采用高锰酸钾预氧化与微滤膜联用处理微污染原水试验结果表明:出水浊度小于0．1NTU,Fe的去除率达到97％以上,对浊度、CODMn、Fe、Mn等均有较好的去除效果。     

预臭氧化与臭氧生物活性炭同步去除饮用水锰含量的研究

Innovation and Its Governance Process in Italy

Almost everybody, almost everywhere, speaks and writes about innovation: highly qualified and esteemed people covering key offices. Basically, the matter is debated within the framework of conferences, meetings, symposiums, articles put out in specialized, niche newspapers as well as in mass-circulation ones. Apparently it sounds positive, as innovation seems to have become the main theme, towards which the best efforts are worth being directed. The issue of China and India is now in the limelight. The way out is easy: just more innovation. And what about global competitiveness of Italy, or brain drain? What of GDP increasing less than the average in Europe? Tourism dropping off? Industrial delocalization increasing? What of such an inefficient public administration? The answer is one and only: There is a need for more innovation! That makes a lot of sense somehow; the negative aspect is that, most of the times, the core meaning and the fundamentals of innovation are not really deepened and understood; poor attention is paid to the reasons why the situation of Italy is unsatisfactory as regards innovation or to the main problems to be figured out for such a stalemate to be overcome. This short essay is going to focus on these issues, with a view to foster debate leading to prompt and realistic decisions.
