The current situation of water shortage and pollution and cracking method

Present situation of water resource in China

1, the shortage of water resources present situation, we know that water is the source of life, the human body is water 90%, she is indispensable to human survival and development of important natural resources. While China's per capita water resources is only 2300 cubic meters, was only about a quarter of the world per capita level, a normal year the annual water deficit of more than 400 cubic meters or so. In the United Nations commission on sustainable development statistics in 153 countries and regions, China's per capita water resources quantity ranks 121th, per capita water resources is only a quarter of the world's average, is the world's 13 one of the poorest countries in per capita water resources. Let suffering from scarcity of water industry. In addition, with the speeding up of industrialization and urbanization in our country, the industrial and urban sewage emissions is increasing, the original sewage treatment facilities have been unable to meet the demand of the new sewage treatment, sewage disposal facilities of update and upgrade to perfect the imminent drainage solution. Industry experts point out that, if he is not paying attention, timely solve, a nationwide water crisis is inevitable.

water problems caused the central department attaches great importance to the

recently, the ministry of environmental protection standard of science and technology department deputy director Liu Zhiquan in 2011 ( The fifth) Water sector, a senior technology BBS, as one of seven strategic emerging industries planning the first draft of the 'energy conservation and environmental protection industry development plan has been completed, and report to the State Council for examination and approval. In the development plan, involving the basic to determine the content of the water industry, in addition to the need to increase water core technology strength, relying on special offer water technology, equipment, promoting environmental protection industrialization will be the 'twelfth five-year' period is an important task of environmental work. 9%.

in this case, the personage inside course of study is generally believed that should control of water pollution as early as possible, to speed up the construction of water conservancy projects, gradually realize the optimal allocation of water resources. And improve the level of comprehensive utilization of water resources, one of the most important one annulus is the use of advanced water treatment equipment to improve the industrial wastewater and urban sewage purification treatment ability.

crack water shortages of

to solve water pollution and ensure the safety of drinking water is a major strategic task relates to the national economy and people's livelihood. We have learned, 'twelfth five-year' period, Ministry of Science and Technology will be arranged in the national science and technology major projects to protect water resources and water environment pollution governance research task. Among them, high membrane treatment technology.

it is introduced that membrane water treatment technology has the characteristics of water quality, can meet the improving drinking water, sewage water, reclaimed water reuse and other kinds of demand, is widely used in medicine, food, process water, desalination, and other fields, and occupy the important position. At present our country has built more than symbolic membrane method of large water supply engineering, wastewater recycling and seawater desalination project.

according to authoritative organization statistics, in 2004 China's film industry market size is 7. 5 billion yuan, increased to 20 billion yuan in 2008. 'Twelfth five-year' period, China's film industry will enter a rapid growth. Tsinghua university, director of the institute of environmental protection industry Fu Tao said: 'the film technology of market opportunity is coming, predictably, membrane technology will become the '12th five-year' water market leading technology. '

according to many years of industry experience, filter the source water treatment equipment co. , LTD. , chief engineer zhang said the scientific direction of industrial waste water treatment should be a system solution of waste water and quantitative fine management system, the formation of clean production, wastewater treatment and reuse, and vigorously develop water treatment is the most fundamental to break water shortage and pollution of method, in addition we also want to undertake a water-saving knowledge propaganda, let the national people's action, and to protect and save our limited natural is also very important.
