At present, for the control needs of the water treatment industry, PLC performance characteristics of the controller is the most suitable for this industry, and therefore also in the water treatment and distribution control system has been a large number of applications to water control, for example, Plant within the scope of the required water, dosing, filter, water and other monitoring and control functions are very common to play the role of the master. From the management level of the whole group, it is often used SCADA system for macro command, scheduling and management, and truly achieve the "centralized command, decentralized control" effect and requirements. Correspondingly, a large number of man-machine interface, display instruments, etc. will have a relatively large demand.
In the water quality monitoring, water state measurement, etc., but also need to use a large number of instrumentation products. These instruments used in the water treatment industry are mainly divided into process instruments and analytical instruments. The process instruments include temperature and pressure transmitters, liquid level meters, flowmeters, valve products and actuators. The type of instrument is very large and thin, must be based on the actual treatment of water quality, type, combined with the corresponding treatment process for use. For different types of sewage such as industrial waste water, biological waste water, its processing technology may vary widely.
As a result of the widespread use of distributed control system for hierarchical control management, then rely on the industrial communication, but also has a high demand. In recent years, from the more popular field bus, to relatively new industrial Ethernet, have been the scale of the application, the effect is more and more improved. It is worth mentioning that, in order to meet the remote monitoring and other special occasions, the application of wireless communication technology is also involved in the water treatment industry, and achieved good results, which is a wired communication, it is undoubtedly a good supplement.
In the implementation of the link, the application of the inverter is also increasingly common. Inverter and pump type load, with multiple advantages, relative to the valve, baffle adjustment, frequency control can run the speed control object in the energy-saving state, from the principle to achieve a lot of cost savings; the same time, The use of frequency converters also reduces mechanical losses, reduces the impact of the actuator, the grid can also play a protective role.
China's water industry is still in its growth stage. Although the government has determined the strategic goal of water marketization, the lack of systematic research on the path of water market reform is not perfect. The market policy system of urban water is not perfect. In view of the differences in the situation, Accounting and water price adjustment time and intensity of a certain degree of uncertainty, resulting in long-term investment characteristics of water investment is facing greater policy risks, while the various types of capital competition to the current water market competition was exacerbated.
In addition, the market concentration is low, the lack of industry leaders, regional monopoly characteristics. According to industry attraction and technical relevance to the industrial chain to extend the vertical, and water management has become the main direction of development. Operational management capabilities, capital operation capabilities, market development capabilities, technology application and development capabilities and risk control capabilities have become key success factors for water industry companies. Seeking the balance between market share and investment income is the focus of the growth of China's water business at this stage.
In the context of the international financial crisis, China has adopted a policy of expanding domestic demand, promoting economic growth, and putting environmental protection in a prominent strategic position. In the fourth quarter of 2008, the new 100 billion yuan of central investment, to invest in energy-saving emission reduction and ecological construction funds of 12 billion yuan. For the focus of the watershed water pollution control project investment and for urban sewage and waste disposal facilities, sewage pipe network construction speed of up to 6 billion yuan, the former investment of 1 billion yuan, the latter 5 billion yuan. It can be said that the sewage treatment industry usher in an unprecedented opportunity for development.
Whether from the industry development prospects or growth trend, the value of water treatment and wind power and other concepts can be par with. "Environmental high-tech" banner seems to make people more willing to believe that the concept of water treatment worthy of a higher price-earnings ratio. In the city water supply growth is gradually stable and the price increase in the optimistic expectations, the water company operating and profitability sustainability and stability will not have much ups and downs. Therefore, domestic and foreign water giants have been running in recent years enclosure.
At present, China's water development has shifted from the big city project to the competition of small and medium-sized cities, from domestic companies and domestic companies to the domestic companies and domestic companies, domestic companies and foreign companies, foreign companies and foreign companies compete. Especially in recent years, the international water giants to join, industry competition hot upgrade.
Since 2002, the state allowed foreign investment in the water industry since the optimistic view of China's future prospects of foreign water companies rely on the "investment-driven operation" model in China Happy Valley resort time-tested. In recent years, the French Veolia Water Company has acquired the 45% stake in Lanzhou Water Supply Group for RMB1.71 billion; 100 million yuan of Tianjin City North Water Co., Ltd. 49% of the state-owned shares; Sino-French water in 2007 to 8.95 billion yuan in the successful bidder Yangzhou project in 2009 and harvest the Tianjin mustard project.
In addition, the domestic water companies listed also stepped up integration. Recently rumors that Wuhan Holdings is expected to be injected into the local water distribution network assets, stock prices. Then, yesterday, Hongcheng Water Industry announced that the proposed acquisition of major shareholders of the acquisition of water management assets, the acquisition of listed companies will have a complete water treatment industry chain, which is conducive to enhancing the competitiveness.
Although placed in front of the cake is huge, but the degree of marketization is not an important bottleneck in the development of the industry. Industry veteran told reporters that the current sewage treatment industry in the degree of market is not strong, the level of business is also uneven, so that high-end enterprises is difficult to become bigger and stronger. And many projects on the tender is also widespread local protectionism. He said, "Now a lot of projects are highlighted administrative characteristics, the relationship between units near the water.However, sewage treatment is actually a considerable technical requirements of the industry, if not set a higher threshold in the industry, good business can not take engineering, technical level Not so high enterprises do bad works so go on, not only affect the development of the industry itself, but also cause serious waste of resources.
In addition, the industry for the existing listed companies advertised the issue of nationalization of equipment also questioned. He said that nationalization should serve as a trend, which is the cornerstone of the healthy development of the industry. But not as the concept of market speculation. Now China's water treatment industry is still in the late start of the low level of technology, key equipment, self-made and mass production, in the short term will also bring about reducing production costs and affect the quality of the two consequences. The former is undoubtedly beneficial to the company, but the latter will need to overcome through a long period of development. "From the current domestic water treatment enterprises to master the core technology point of view, the degree of nationalization should not be too fast, nor too fast."
"The future development trend of water treatment is what?" Facing the reporter's question, wealth securities analyst Zou Jianjun said BOT project-based cross-regional mergers and acquisitions will become the future development trend of domestic water companies, but the domestic water company focused Is not high, mergers and acquisitions will certainly encounter great resistance. Xie Daocheng also expressed the same meaning, but he is optimistic about cross-basin industry mergers and acquisitions, he said, "in the investment operation on the basis of saturation, the vertical integration of large companies will begin, the water company will eventually transition to provide services for the Lord."
