During the period of the 11th Five-Year Plan period, some experts have proposed to introduce a tax on water resources as soon as possible to rationalize the consumption of water resources and control the water resources in a quantitative manner so as to maintain a balance in the use and distribution of water resources. Experts believe that for a long period of time, China's water supply and drainage price system can hardly reflect the scarcity value of water resources. Enterprises use one type more than one, and after implementing a stepped water price system, companies that use more water must spend more money.
Water resources management and control policies tighten the chemical industry is facing high pressure
The use of taxation as a signal to indirectly affect market prices, and the effectiveness of allocation and protection of water resources is better than administrative pricing, and is an effective way to solve water resources problems. Recently, the No. 1 Document of the Central Committee in 2011 “Decision of the Central Committee of the Communist Party of China and the State Council on Accelerating the Development of Water Conservancy Reform†was released. The most stringent water resources management system and the promotion of water price reforms will be implemented as soon as possible. The industry analysts believe that as the state tightens the use of water resources, the chemical industry, which is both a big water-consuming and a big pollutant, will face the “three red lines†outlined in the document: total water use control, water efficiency control, and restrictions. The test of pollution. Chemical companies must attach great importance to early actions and early decisions, and gradually reduce the costs of resources and environmental protection policies.
The shift of the center of gravity of the PVC industry to the production water challenge
At present, the large-scale PVC projects newly established in the chlor-alkali industry are concentrated in the west of energy-enriched areas. The initial scale of the project is increasing, and the development of parks and clusters has become the mainstream. Taking Erdos in Inner Mongolia as an example, currently the PVC projects of Junzheng Energy, Dongfang Hope, Guangdong Hongda Xingye, and Evelong Group are all in full swing. The projects are concentrated and the scale of production capacity is huge. The coal and power resources in the region are abundant, which brings advantages of raw material costs for the development of PVC projects, but at the same time companies will also face the issue of water use. Water resources are relatively scarce in most parts of the western part of the country, and industrial water use is even more tense. According to statistics, 80% of the country's freshwater resources are located in southern China, and most of the energy is located in the north, mainly coal. The faults formed by coal and water resources may pose challenges to the development of the chlor-alkali industry in the western region.
Therefore, for chlor-alkali enterprises, how to minimize the total amount of water used in the development of new projects and improve the efficiency of water use are on the agenda. It is understood that many chlor-alkali projects currently under construction in the western region all take the water balance of the park as the focus of project planning. According to Ningxia Iridite company sources, Intelli specializes in large-scale salt chemical projects such as caustic soda and polyvinyl chloride in Guyuan County. It will “quote the Yellow River into the park†to solve the problem of water use, and the higher cost of water requires the project. Water saving and recycling cycles must be maximized in design and construction.
Enterprises Should Accelerate the Application of Advanced Technology for Water Saving and Recycling Water
The national industrial policy and the development trend of the industry show that the cost of water for chlor-alkali enterprises will continue to rise in the future, and the economic benefits of high-efficiency water use will be directly reflected in the production costs and environmental protection costs of enterprises, which will affect the overall competitiveness of the company. During the construction of the project, the main project and water saving measures shall be designed, constructed, and put into operation at the same time; and the assessment of water use shall be strengthened for all internal departments. The water drawing and water use unit shall have a water use plan in place, a water saving goal in place, and water saving measures in place. The water management system is in place.
As the country’s first batch of circular economy pilot units, Xinjiang Tianye has now formed an annual production capacity of 1.2 million tons of PVC and 900,000 tons of caustic soda. With the expansion of the scale of enterprises, the issue of the utilization efficiency of water resources becomes more prominent. During the “Eleventh Five-Year Plan†period, Xinjiang Tianye undertook the national science and technology support project “Integration and demonstration of efficient water-saving technologies for chlor-alkali enterprisesâ€, and built the first dry acetylene in China, the biochemical treatment of the polymerization mother liquor, and the supernatant closed circuit. Cycle, zero-analysis of mercury-containing waste acid and other demonstration devices.
Located in Wuhai, Inner Mongolia, Junzheng Energy Chemical Co., Ltd. implemented a “source elimination planâ€. According to the water quality characteristics of various types of wastewater, the centralized wastewater treatment method was used to concentrate various types of waste water, such as the wastewater discharged from each system and the boiler pickling wastewater. The waste water treatment stations are separately treated. A part of the treated waste water is used for the ash removal system or coal yard and ash field spray water, and part of it is used for the cooling water of the chemical company's nonferrous metal smelting equipment, so that the entire company's industrial waste water can be used.
