Observation of sewage treatment
After more than 30 years of rapid development, China's rapid progress in sewage treatment has shocked the world and attracted international attention.
If we look back on the past development path and think about our current situation, it is not difficult to see that there is a certain gap between European and American countries and China in some aspects of sewage treatment. This gap is mainly reflected in the following aspects:
The first is undoubtedly the underground sewage treatment plant. The European and American countries are cautious and shy about the underground sewage treatment plant. Although the Dutch are famous for taking risks in the era of great navigation, although they developed anaerobic ammonia oxidation technology and aerobic Granular sludge technology, but it is not aggressive in underground sewage treatment plants, there is only one in the country; IWA (International Water Association), which represents one of the highest levels of international sewage treatment, is also very rare in underground sewage treatment plants Involved, there are many trivial meetings on nutrient removal and recycling, models, etc. over the years; and the so-called WEF, another so-called industry organization, has rarely been involved for decades, and the short-sightedness can be seen. And some international big coffees are even more worried about the specific narrow matters of underground sewage treatment plants such as the cost, risk, design requirements, operation control, etc., which makes people laugh. In this regard, it is clear that China ’s understanding of underground sewage treatment plants goes beyond the above. First of all, underground sewage treatment plants are one of the important choices for the development of society. This is the narrow place where European and American countries have never jumped out of sewage to see sewage. I always walk around the circle of sewage and ca n’t jump out. Secondly, the underground sewage treatment plant is the leader of ecological construction and a reflection of the implementation of ecological civilization in the industry. This major theoretical innovation has clearly surpassed the narrow sewage treatment. During the construction process, our eyes have been on the entire human social life system, sewage treatment has been regarded as a chess piece in human society, and we are thinking about how to play the whole game well. In this respect, European and American countries are behind us in understanding the status and role of sewage treatment in society.
Secondly, we are already thinking about the extreme path of sewage sludge, what is it and how to achieve it. This kind of thinking is not available in European and American countries. The conservative style makes it stand still, and we are doing the cultivation of the extreme. .
In summary, China ’s sewage treatment has achieved great historical transcendence. In understanding the status of sewage treatment in human society, on the road of practice, and in the perspective of relaxing history, our ultimate cultivation will definitely lead This colorful era!
