Study On Water Balance Test And Water Saving Potential Evaluation Of Sanli Woolen Textile Limited Company

The current situation of water consumption in our country lies in the shortage of water resources,extensive utilization and low efficiency.With the advance of urban construction and the development of industrialization,the contradiction between the supply of water resources and the demand for water resources will become more prominent.To maintain the sustainable use of regional water resources and the sound and stable development of the economy,it is necessary to strictly implement the requirements of the "three red lines",strengthen the management of water resources users,minimize the use of unreasonable water resources,and continuously improve the efficiency of water resources utilization.The water balance testing work has been able to grasp the current situation of water use in water use units,explore their water-saving potential,and continuously improve the level of water use per unit.As a result,in the past 30 years,water balance testing has made great progress in agriculture,industry,and life.Because most of the current water balance tests pay attention to the test itself,the lack of water saving potential excavation and transformation problems,so that the test work is basically in the form,and does not fully achieve the purpose of improving the efficiency of water use per unit.These problems also exist in Hebei province,where water balance testing was carried out at an early stage,and how to make better use of the role of water balance testing in water conservation management,and find a relatively complete model for water balance testing and results analysis and application.Then,it is an important issue for the water use unit to put forward rationalization suggestions on the improvement of water resource utilization efficiency and the exploitation of water saving potential.Gaoyang County is short of water resources and serious groundwater exploitation.As a pillar industry,the textile industry has huge water consumption,strengthen water-saving management,fully play the role of water balance testing to improve the efficiency of water resources utilization,and continuously improve the water use efficiency of water units is an urgent task.In order to ensure the science and effectiveness of the test work,in this paper,the water balance test in the test preparation,system division,test cycle determination,test method,ways selection and other key issues are studied,and these studies in Hebei Sanli Wool Textile Co.,Ltd.water balance test work and obtain effective results.The quota comparison method is used to compare the indexes of unit product water consumption and reuse rate of industrial water with regional standards,so as to grasp the current water level of enterprise,by introducing the formula of efficiency coefficient of industrial water resources,we can intuitively see the difference between the domestic and foreign advanced water use efficiency of the enterprise.Based on the test results,the paper puts forward the scheme of improving the production equipment and upgrading the flushing water system to reduce the amount of new water per unit,and calculates the water saving degree.Through the economic analysis method,the return cycle of water-saving investment is calculated.Through this series of studies,it has fully explored the water-saving potential under the current situation of Sanli Woolen Spinning Co.Ltd.,provided practical suggestions for its further energy conservation and emission reduction work,and eventually reduced the amount of water taken from enterprises,increased the amount of repeated water consumption,and reduced the discharge of sewage.It provides a basis for making decisions on the water saving planning of enterprises.Through the research of water saving test and analysis and evaluation in textile mills,this paper proposes a relatively complete water saving template for local enterprises,and also provides reference for other water saving units.At the same time,the application of the technology assessment method and the economic benefit analysis method has improved the water balance test in Hebei province.
