17日，格兰富联合国际水务智库(GWI)在北京发布了一份涵盖中国水资源利用、污染治理及可持续发展等内容的白皮书。白皮书指出，在2007年至2017年间，中国的污水处理量从176.5亿吨增加至569.8亿吨，实现了逾三倍的惊人增长。不过，与全国范围内的污水排放总量相比，这一处理规模仍然有所不足。

全球泵业巨头格兰富中国区水务事业部总经理张杰对中新社记者表示，中国在过去20多年里，污水处理得到巨大发展，多数城市污水处理率超过90%，但在质量和效率等方面，与一些发达国家相比仍有较大差距，中国在污水处理领域还有很大的发展空间。

白皮书指出，现有污水厂的低效运行和空置等现象削弱了实际污水处理能力，导致一些地区依旧有污水未经处理直接排放。除污水处理厂之外，不少地方配套的污水管网在数量和质量方面存在问题，如新建管网铺设长度不足、已建管网雨水和污水混接现象严重、因管网材质差或维护不力等原因造成的管道破损等。

另外，张杰表示，中国城镇污水处理率比较高，但广大农村地区的污水收集管网还不发达，收集率也不高，整体规模仍有增长空间。即便是在污水处理能力较高的城镇，还有向更高质量和效率升级的巨大空间，比如对处理后的污水水质，未来可能要求其达到更高标准。

缺口意味着机会，这也吸引了不少外资企业的关注。白皮书指出，截至2019年，国际解决方案提供商纷纷表示有意将其污水处理厂的优化方案带到中国市场来，其中许多先进方案在欧洲、中东、拉丁美洲的缺水地区已成功实施，有的已实现节能(千瓦时)高达40%、降低能源成本高达50%、降低化学品消耗量达35%的显著成果。

格兰富中国区战略及业务拓展总监胡方舟表示，在污水处理、水资源利用、节能减排等绿色领域，中国是世界上增长比较快的市场之一。包括该公司在内的大量外资公司对中国市场充满期待，格兰富去年就将中国作为其全球研发中心。

胡方舟说，中国其实在许多方面的创新已经“走在了前面”。除了引进国外的经验外，中国不少本土化的解决方案已经非常先进，可以实现“走出去”。(完）

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)
