China's water-saving valves are tightening the water lever
The Eleventh Five-Year Plan first proposed that by 2010, the unit water consumption for industrial added value will be reduced by 30% and the effective utilization factor for irrigation water for agriculture will be raised to 0.5. How to achieve this goal? Reporter with the "water-saving line of China," Central News interview learned in Zhejiang, Shanghai and Jiangsu, supporting the introduction of a series of water-saving measures around to improve water efficiency and achieve the coordinated development of water resources and economic and social development. Pollution control is the largest water-saving "Wash rice dishes in the 50s, 80s fish absolutely, the 1990s physical and psychological damage." With the rapid economic growth, Jiangnan Water Village is facing "growing troubles," guarding the river network downtown "water shortage." "More than 50 days did not rain, this year the Huangpu River salty more than two months earlier than in previous years." Shen Yiyun, deputy director of Shanghai Municipal Water Authority said with emotion: "Although surrounded by water in Shanghai, but cocoa drinking water is too small! Of the river water quality is too poor, Shanghai last year, the water quality of the 16 rivers were evaluated, 22% of the river water quality is still 5 categories, there are more than 40% of the bad 5 types of water. "Not just Shanghai, Yangtze River Delta The same situation in the region's water resources is not optimistic. "The lack of water in the Taihu Lake basin is good, and the wastewater is mostly sewage!" Ye Shuren, deputy director of the Taihu Lake Basin Administration, said that the water quality in the Taihu Lake Basin exceeded 89.7%, and 70% of the water in Taihu Lake was already eutrophic. "Water quality problems of water shortage, the fundamental way is to prevent and control water pollution, pollution control is the largest water-saving!" Shen Yiyun said that Shanghai is launching "Wanhe Renovation" of the new three-year environmental plan, from 2006 to 2008, The city will invest more than 200 billion yuan to rehabilitate the water environment, planning to complete the remediation of thousands of rural rivers in 2008, turning the black-smelling siltation into a rippling wave. "Discharge of 1 ton of sewage will not only contaminate 7 to 8 tons of clean water, but also 10 to 20 tons of purified water to be diluted, so pollution control is the fundamental water." Yiwu City Water Authority Wang Birong introduction, Yiwu become a country Level water-saving society to build pilot cities, is vigorously promoting new industrial water-saving technologies and cleaner production concepts, improve water reuse. "The development needs more scientific development, from attracting foreign investment to investment choice and capital change." Wei Zhang, director of Zhangjiagang City Water Resources said that at present, pollution has become a new project in Zhangjiagang City, a rigid bar, does not meet the water use standards , Do not meet the emission intensity limits, do not meet the ecological priority of the project will be "bright red." Since 2000, the city has rejected or discouraged more than 400 newly-started industrial projects with a total investment of over 6 billion yuan. The amount of water and the line, with the concept of water development has brought changes in the development mode of change. Nowadays, in the Yangtze River Delta region, "measuring water and hydropower development" has become the content of many local plans. Starting from this year, Shanghai has formally incorporated water consumption per 10,000 yuan of GDP into the statistical index system of Shanghai and has become a mandatory indicator of the national economic and social development plan. Statistics from Shanghai Municipal Bureau of Water Supply show that Shanghai's water consumption per 10,000 yuan of GDP dropped from 184 cubic meters in 2002 to 125 cubic meters in 2005. Shanghai will initially build a water-saving social city by 2010 with a production of 10,000 yuan Total water consumption dropped to 105 cubic meters. Shen Yiyun said that to achieve industrial water-saving, one is to encourage the development of water-saving industries, focusing on high-water-consuming industries, vigorously promote water-saving technology, water-saving technologies and water-saving equipment, reduce process water, and continuously improve the reuse of industrial water rate. Shanghai last year, the city's industrial water recycling rate of 80.9% in 2010, the target is to rise to 82.4%. On the other hand, water abstraction permits are not granted to high-water consuming industries that do not comply with Shanghai's industrial policies and to projects that fail to pass the water-saving certification. Shanghai Asia Pacific Brewery Co., Ltd. focus on efficient recycling of water, packaging machine bottle washer, sterilization machine, and brewing plant wort boiling machine, the production process will produce a lot of condensate. Setting a record of the lowest unit consumption of beer products in major domestic beer enterprises in 2005: 4.77 tons. Zhejiang Province, Zhang Guofang, deputy director of the Department of Water Resources introduced that although Zhejiang's economy is very developed, but agriculture is still the province's major water users. On the one hand, increased investment, on the one hand grasp the system of construction, "Tenth Five-Year" period, Zhejiang invested a total of 3.7 billion investment in water-saving irrigation projects, the implementation of "one hundred million acres of billion square water-saving projects," has completed channel lining defense Permeability of 29,563 km, the construction of sprinkler area of ​​87,000 mu, the development of water-saving irrigation area of ​​458 acres, the new irrigation area of ​​68.9 hectares, water-saving agricultural water saving capacity of 568 million cubic meters, the equivalent of eight West Lake water storage . The use of water lever, sub-quality water, high quality and low price use of water lever to promote the quality of water, high quality and low price, to achieve water conservation. In order to give full play to the leverage of water prices, Wuxi City, adjusted the water fee twice, from the previous few cents adjusted to more than 2 yuan, for excess water, but also add 2-5 times the water fee. At the same time, through taxation policies, incentives and encouragement and support of water-saving advanced enterprises. So, under the command of the water lever, many companies have each supernatural power, innovative way to save water. Dyeing and printing enterprises are the traditional big water consumers, in the past, water is Wuxi Xin Jiangmin Printing and Dyeing Co., Ltd. General Manager most worry about things. He told reporters that from 1992 to 1994, the company hit seven deep wells in a row, pumping less than a year to do the water. With tap water, 2.7 yuan per ton, too expensive. How to do? In 2000, after the deep well was sealed, the company resolutely set up its own water plant, after the primary treatment of the river as production water. The result is only about 0.4 yuan per ton processing costs than water a year can save more than 280 million. Water saving has brought real benefits to the enterprise. "July 1 this year, Yiwu City, high-pollution, high water consumption and other special industries, the price of water by 3 yuan / ton adjusted to 6.6 yuan / ton, not water-saving ah!" Zhejiang Jin Ge Knitting Co., Said that initially determined to build a sewage treatment and reuse system, and now I plant 80% of the printing and dyeing wastewater recycling, annual saving 720,000 tons. The company produces economic benefits of 4.75 million yuan each year due to wastewater reuse. "Using drip irrigation technology can save 50% water." Master Zhu of Dendrobium officinale Plantation in Senyu Group said: "In the past, we used artificial irrigation and the daily water consumption per acre area was between 2 and 3 tons. Now there is only 1 To 1.5 tons, saving 0.5% of water consumption and saving 50,000 tons a year. "Gao Youkun, director of the Water Resources Department of the Ministry of Water Resources, believes that to achieve the water resources utilization targets set forth in the 11th Five-Year Plan, we must comprehensively promote Water-saving society. The sustainable use of water resources as an entry point, the full implementation of gross control and quota management, highlighting the strengthening of water conservation, protection and optimization of configuration; to encourage the development of recycling economy, the integrated use of economic, legal, science and technology, engineering and other measures, and more To manage water resources and improve the water environment.
