A white paper covering China's water use, pollution control and sustainable development was released by the granfu international water think tank (GWI) in Beijing on Monday. Between 2007 and 2017, China's sewage treatment capacity increased from 17.65 billion tonnes to 56.98 billion tonnes, a staggering increase of more than three times, according to the white paper. However, compared with the total amount of sewage discharged nationwide, this scale of treatment is still insufficient.
Global water pump industry giant grundfos China division general manager zhang jie of China news agency reporters that China in the past 20 years, sewage treatment have huge development, most of the urban wastewater treatment rate of over 90%, but in terms of quality and efficiency, compared with some developed countries there is still a large gap, China also has the very big development space in the field of wastewater treatment.
According to the white paper, existing sewage treatment plants are inefficient and empty, which weakens the actual capacity of sewage treatment, resulting in untreated sewage discharge in some areas. In addition to sewage treatment plants, there are problems in the quantity and quality of the supporting sewage pipe network in many places, such as the lack of laying length of the newly built pipe network, the serious mixing of rainwater and sewage in the established pipe network, the pipeline damage caused by the poor material of the pipe network or poor maintenance.
In addition, zhang jie said, China's urban sewage treatment rate is relatively high, but the vast rural areas are still underdeveloped sewage collection network, collection rate is not high, the overall scale still has room for growth. Even in cities and towns with high sewage capacity, there is plenty of room to upgrade to higher quality and efficiency, such as the quality of treated sewage that may be required to meet higher standards in the future.
Gap means opportunity, which also attracted the attention of many foreign enterprises. White paper points out that by the end of 2019, the international solution providers have expressed interest in the optimization scheme of sewage treatment plant to the Chinese market, including many advanced solutions in water scarce areas of Europe, the Middle East, Latin America has been successful, some of which have been implemented energy (KWH) is as high as 40%, reduce energy costs, reduce the consumption of chemicals is as high as 50% 35% of significant results.
China is one of the fastest growing markets in the world in green areas such as sewage treatment, water resource utilization, energy conservation and emission reduction, said hu fangzhou, director of strategy and business development in China for GRFT. The company is one of a number of foreign companies looking to China for growth, and glencore last year made China its global research and development center.
In many ways, Mr. Hu said, China has been 'ahead of the curve' in innovation. In addition to the introduction of foreign experience, many of China's localized solutions have been very advanced, can achieve "go out". (after)
