On the 25th, Zhao Hualin, Director of the Department of Pollution Prevention and Control of the Ministry of Environmental Protection, stated at the “2011 Urban Water Industry Strategy Forum†that the increasing difficulties in the reduction of pollutants pollution is one of the grim situations facing China’s current water pollution prevention and control work.
Regarding the progress made in the "Eleventh Five-Year" water pollution prevention and control work, Zhao Hualin said:
First, the overall environmental quality of water has been improved. In 2010, the average concentration of permanganate index in the national surface water control section of the country was 4.9 mg/l, which was 31.9% lower than in 2005. The ratio of the seven major national water control sections better than the three types of water quality increased from 41% in 2005 to 59.6%; Second, the regulatory standards for water pollution prevention and control gradually improved; Third, the total amount of water pollution discharge was effectively controlled; Fourth, drinking water safety The protection work has been strengthened; Fifth, progress has been made in the prevention and control of water pollution in key river basins.
Zhao Hualin pointed out that during the “Twelfth Five-Year Plan†period, the difficulty of emission reduction of pollutants has continuously increased: the pollutant discharge constraint index has been increased from two to four, among which the newly added binding index has reduced nitrogen oxides and ammonia nitrogen by 10%. Oxygen demand and sulfur dioxide continue to reduce emissions by 8%.
Regarding China's environmental goals during the "12th Five-Year Plan" period, Zhao Hualin said that environmental issues are still the bottleneck of China's development, and the environmental pressure China faces is greater than any country in the world, and nitrogen oxides may be the most difficult to reduce!
Experts at the meeting and members of the business community believe that the development and promotion of advanced and applicable technologies for conservation, substitution, recycling, and pollution control are critical to achieving China's environmental goals during the 12th Five-Year Plan period.
"The current difficulties in the recycling of reclaimed water are: low-end recycling, and the driving force of economic interests is not enough, it is difficult to form a virtuous circle." Sun Xiaowei, chairman of Aster Water Technology Co., Ltd., told the China Economic Times on the 25th.
Fu Tao, director of the Water Policy Research Center of Tsinghua University and editor-in-chief of China Waternet Consulting, pointed out that the reform of the water industry must be deepened at the same time. The driving force of China's water reform is to attract investment. After market-oriented reforms, government investment responsibilities have long been ignored. In order for the public to pay only to cover costs, but also to allow enterprises to make a reasonable return, it is necessary to establish a subsidy mechanism for the operation of municipal facilities.
Sun Xiaowei believes that China's water development cannot be separated from the overall planning and planning of the government. In addition to formulating corresponding policies, the competent government departments should also respect the laws of the market. Only by opening the chain of policy, demand, supply, and supervision, and forming a virtuous circle and interaction can we guide the healthy and orderly development of the industry with advanced and scientific methods.
A Wire Brush is a tool, consisting of a handle, usually wood or plastic, occasionally bone, and a brush. The brush is usually made from a large number of steel wire bristles. The steel used is generally a high carbon variety and very hard. Other wire brushes feature bristles made from brass or stainless steel, depending on application. Wires in a wire brush can be held together by epoxy, staples, or in some cases one continuous wire. Some types of wire brushes can also be used on an angle grinder or electric drill.
The wire brush is primarily an abrasive implement, used for cleaning rust and removing paint. It is also used to clean surfaces and to create a better conductive area for attaching electrical connections, such as those between car battery posts and their connectors, should they accumulate a build-up of grime and dirt. When cleaning stainless steel, it is advisable to use a stainless steel bristle wire brush, as a plain carbon steel brush can contaminate the stainless steel and cause rust spots to appear. Brass bristle brushes are used on softer surfaces or in potentially flammable environments where non-sparking tools are required. Wire brushes are also used to clean the teeth of large animals, such as crocodiles and pigs. they are also used widely in surface engineering to clean the castings to paint the castings.
