Papermaking is listed as the early focus of the national industrial water-saving ten-year goal

according to information, recently, the State Economic and Trade Commission, the Ministry of water resources and other six ministries and commissions jointly issued a notice, determining that China's industrial festival is above the ten-year goal of water when we install universal experimental machine fixtures. The notice requires that while focusing on water-saving work in high water consumption industries such as firepower, textile, petroleum, paper making and metallurgy, we should guide the water-saving work of all industrial enterprises and comprehensively promote the construction of water-saving enterprises

at present, the shortage of water resources has become an important factor restricting national economic and social development. The key to solving this problem is to strengthen the conservation, protection and scientific utilization of water resources and strive to improve the utilization rate of water. China's industrial water intake accounts for 20% of the country's total water intake, and the industrial discharge of wastewater accounts for about 49% of the total wastewater discharge. The vast majority of toxic and harmful substances are discharged into the water body with industrial wastewater, resulting in the pollution of drinking water in many cities and towns by different procedures, and some water resources are forced to be abandoned, exacerbating the shortage of water resources. At the same time, the waste of water resources is also very serious. The overall level of industrial water use efficiency is low. Serious waste of water such as running, emitting, dripping and leaking is widespread, and industrial water saving has great potential. For this reason, the overall goal of water saving with shock and vibration in industry before 2010 proposed by the "notice" is to control the growth of water intake at 1.2% under the condition that the average annual growth of industrial added value is about 10%; The water reuse rate has increased from 50% at present to 60% in 2005 and 65% in 2010; And the error decreases with the increase of load. The water intake of industrial added value decreased from 340 cubic meters at present to 170 cubic meters in 2005 and 120 cubic meters in 2010
