Future development trend：

In the past few years, the industrial capacity of the sewage treatment industry has undergone qualitative changes, which are mainly caused by two aspects, one is the rapid increase in the number of sewage treatment plants, and the other is the rapid increase in the overall treatment capacity. There are more than 3,000 sewage treatment plants, and the standard amount of industrial wastewater discharge was 54 billion tons in 2011, and will exceed 76 billion tons in 2012. The change of quantity also causes the change of quality to some extent.

By studying the development process, technical standards, governance level and regulatory system of urban water in the United States and other developed countries, it can be found that although China has a large-scale sewage treatment capacity, it is only reflected in the quantity, and there is still a large room for improvement in the quality of the level of governance. For example, membrane treatment technology in sewage treatment, sludge treatment, recycled water utilization, etc. If China wants to catch up with the gap with other developed countries in quality, it needs to increase investment in the supervision mechanism, investment and financing mechanism of sewage treatment and the industrial chain of all links, so as to improve the overall level of urban sewage treatment and effectively control water pollution.

The "2014-2018 China Sewage Treatment Industry Market Outlook and Investment Planning Analysis Report" shows that with the continuous advancement of modernization and industrialization in China, the total amount of wastewater discharge continues to grow. From 2001 to 2012, the total amount of wastewater discharged in China increased from 43.3 billion tons in 2001 to 68.5 billion tons in 2012, and the total amount of wastewater discharged increased by 25.2 billion tons, an average of 2.1 billion tons of wastewater discharged each year, with an average annual compound growth rate of about 4.3%.

From the perspective of wastewater sources, the growth of total wastewater discharge in China is mainly the growth of urban sewage discharge. The proportion of urban sewage discharge in total wastewater discharge increased from 53.2% in 2001 to 67.6% in 2012. In addition, from 2001 to 2012, the average annual increase of urban domestic sewage discharge was 1.94 billion tons, accounting for 92.2% of the total annual increase of wastewater discharge. From the perspective of the continuous development of water pollution emergencies in our country, it is also mainly the supervision system and punishment of water pollution in our country to be improved.

From the perspective of spatial distribution, it used to be point-like distribution and changed to such a layout as spatial network. What are the benefits of such a shift? At the regional level, the specific capacity of the industry is increasing, and sewage plants are a very obvious industry called economies of scale, and the larger the scale, the better the benefits. In the past, it was formed by a single plant, and if it can be integrated in the region, the scale advantage of a single plant will be transformed into the collection advantage of multiple plants, so this is a very big change.

In this regard, sewage treatment professionals summarized three future development trends according to the qualitative change process brought about by the quantitative change of sewage treatment industry facilities.

First, the overall performance of the industry is improved. The performance of the internal industry has become a top priority, so the national 12th Five-Year major project has a special project to establish a national industry management performance system.

Second, service has become the core task of our industry and the core link of the industry. This is consistent with developed countries, developed countries basically the service industry accounts for the entire environmental protection industry, equipment, investment, construction is about 50%, China is estimated to account for about 10%, so there is such a large space, the internal structural adjustment is facing the demand from construction to development. No one operating subject can occupy an absolute dominant position at the national level, whether it is state-owned enterprises, foreign-funded enterprises, public institutions, or joint-stock companies, all present diversified forms. So asset-based integration opportunities, that's not easy. This is one of the difficulties we face. But on the other hand, it's a great opportunity. If you look at the international asset integration, the early is the United Kingdom to do more successful, it first solve the problem of integration, and then solve the problem of marketization.

Third, from the technical point of view, the water resources problem itself began to appear the trend of watershed, in the past called "more dragon water control", more and more emphasis on the coordination from the basin level, from the basin scale, not only coordination of water resources, but also coordination of recycled water. The greatest benefits can be obtained only when the problem is considered from a watershed perspective.

Therefore, from the perspective of the environment itself and technological progress, the basic conclusion can be drawn that whether from the perspective of resources or the perspective of water environment, there must be a regional solution to solve China's water problem, rather than a point-source solution. Technological progress, social structure changes and promote this group, decentralized program, these two are contradictory, just the opposite and unity of the contradiction between the two, put forward the industry as a whole to achieve the internal needs of regional integration.
