Lutianhua Co., Ltd. actively promotes water-saving initiatives. Author/Source: Sichuan Lutianhua Co., Ltd. Date: 2022-03-26 Clicks: 24 In recent years, Lutianhua Co., Ltd. has been committed to energy conservation, emission reduction, and the sustainable use of water resources, seeking ways to reduce waste while making efficient use of available resources; as a result, it has managed to transform itself from a heavy water consumer into a model for water conservation. The company has been awarded titles such as “Model Enterprise for Energy Conservation and Emission Reduction during the 13th Five-Year Plan Period,” “**Fourth Batch of Green Factories** recognized by the Ministry of Industry and Information Technology,” provincial-level “Environmentally Responsible Enterprise,” “Enterprise with AAA Credit Rating in Terms of Credit Assessment,” and “Water Efficiency Leader among Key Water-Using Enterprises identified by the Ministry of Industry and Information Technology.” Despite these numerous honors, the company remains true to its original aspirations, takes on its responsibilities, and gathers a powerful force dedicated to moving forward together. The company carries out water-saving initiatives in line with the approach to water management that emphasizes giving priority to water conservation, ensuring spatial balance, adopting systematic governance strategies, and taking multiple approaches simultaneously, as well as the theme of the **Ministry of Water Resources’ activities for World Water Day and China Water Week in 2022. The company takes targeted actions, makes breakthroughs in multiple areas, and adopts various measures to promote energy conservation, emission reduction, and the sustainable use of water resources, continuing to tell the \"story of water\". I. Strengthen publicity and education, and establish management systems. Taking advantage of the campaigns held on World Water Day and China Water Week, efforts are made to promote the \"Code of Conduct for Citizens on Water Conservation\" and the \"Regulations on Groundwater Management.\" Employees are encouraged to take specialized quizzes on the \"Learn to Strengthen the Country\" platform, so that each one of them becomes a promoter, practitioner, and advocate of water conservation efforts. Starting with oneself, paying attention to details, and valuing every drop of water, people are encouraged to adopt behaviors that involve conserving, caring for, and protecting water resources, thereby raising awareness among all employees regarding water conservation as well as the importance of safeguarding these resources ； Formulate practical water-saving measures and management systems, establish a sound water pricing system, and encourage the company to take effective water-saving actions under the influence of economic incentives ； By breaking down tasks into smaller components, clarifying responsibilities at each stage, and defining specific roles, everyone works together to ensure that the responsibility for water conservation and reduced consumption is properly addressed. This approach **improves work efficiency and motivation, and it also provides a basis for supervision and evaluation. Strict water usage assessments serve as a solid guarantee for the effective implementation of relevant rules and regulations. II. Improve the efficiency of the production water system and strengthen the implementation of water-saving measures in production. The company increases investment in technology, promotes technological advancement, raises the level of technology used for water conservation, and changes the way production water is utilized, such as switching from direct use of water to recycled water ； Upgrade existing facilities to save water, such as increasing the use of air cooling, reducing water cooling, minimizing or eliminating the practice of discharging thin layers of cold water directly, and improving the recycling of water ； Water-saving measures in production such as the utilization of the new hydrolysis unit and oil water treatment unit in the urea plant, the methanol wastewater stripping unit, the recovery of nitric acid from Zone I and meta-nitric acid to the sulfuric acid tank in Zone III or to the pressurized neutralization acid recovery tower, and the use of ammonia-based desulfurization technology in coal boilers to treat sulfur-containing wastewater, have been implemented in order to achieve water conservation and emission reduction ； In particular, the ammonia-based desulfurization technology generates no wastewater or waste residues, achieving near-zero emissions. III. Actively promote water-saving technologies, facility construction, and evaluation systems. Although the company is located along the Yangtze River and thus has no water shortage, its employees are fully aware of the importance of water conservation. The company currently has AAO systems for advanced wastewater treatment, reclaimed water reuse systems, SBR wastewater treatment units for water treatment processes, integrated MBR wastewater treatment systems, ceramic membrane filtration systems, reverse osmosis systems for water treatment, systems for treating ammonia-nitrogen-containing wastewater in the nitrification stage, inlet buffer tanks for wastewater treatment systems, outlet buffer tanks for wastewater treatment systems, and emergency storage tanks ； Separation of clean and polluted water streams was implemented in various production unit areas; initial rainwater collection systems as well as sewage collection tanks were constructed. The production wastewater, domestic sewage, and initial rainwater collected from these areas are sent to the sewage buffer tank located in the circulating water section of the utility plant, from where they are then fed into treatment systems such as AAO and MBR wastewater treatment units. After being treated to meet the required standards, the water is discharged through the newly built sewage monitoring and discharge outlet ； As the turbid water tank is transformed into a clear water tank, the volume of wastewater discharged has been reduced from the original 440 m³/h to 220 m³/h. This reduction in wastewater discharge significantly cuts down on the consumption of fresh water, bringing both water conservation and environmental protection benefits ； In particular, the successful completion of the reclaimed water project has significantly improved the levels of energy consumption control, technical performance, safety measures, and environmental protection in the facility, thereby completely changing the unfavorable situation in which sewage treatment was dependent on external factors. In order to standardize the collection, transportation, and treatment of wastewater in various production units within the company, reduce the amount of wastewater generated, and ensure that discharges from the company’s main outlets meet regulatory standards, the company has established a wastewater discharge management system, as well as regulations for wastewater collection tanks and emergency tanks in the production areas. It has also developed a plan for identifying abnormalities in the data related to the company’s No. 13 main outlet. The company adheres strictly to the Class A standards set for urban wastewater treatment plants ； The entities responsible for inadequate maintenance and management, as well as those involved in environmental incidents or complaints, are held accountable in accordance with the company’s relevant management regulations. In 2021, the company incurred fines related to wastewater and environmental issues amounting to 100,000 yuan; this serves as a warning and a deterrent. IV. Strengthen groundwater monitoring: Actively implement the Groundwater Management Regulations and intensify efforts to address over-extraction of groundwater in various regions. To accurately assess the quality of the groundwater environment within enterprises as well as the dynamic distribution of pollutants in groundwater bodies, strict supervision over groundwater protection is necessary. Since 2019, 23 groundwater monitoring wells have been installed in areas such as the Shareholding Headquarters, Lüyuanchun, and the Nitric Acid Area, to enhance maintenance, monitoring, and management of groundwater resources. This approach ensures optimal planning, evaluation, design, and operation in the exploitation of groundwater resources, thereby minimizing any potential or existing harm caused by the extraction or discharge of groundwater and enabling the company to achieve maximum benefits in economic, technical, social, and environmental terms. V. Strengthening water resource management and water environment protection. Strengthening the unified management of water resources is essential to ensure their sustainable use, and it is necessary to implement the \"four waters, four fixes\" principle in all aspects. The company focuses on establishing clear metrics, implementing strict measures, and setting firm constraints in order to create a rigid system for water resource management. Through these strong constraints, it enforces control over the total amount of water used, sets quotas, adjusts water prices, and strengthens the regulation of water extraction permits in accordance with the law. Since 2021, the company’s annual water consumption has decreased from 29 million cubic meters to 22 million cubic meters, with significant results ； Strengthen the unified management of water conservation, enhance water resource protection, intensify the control of pollution sources, and accelerate the adoption of new technologies for advanced wastewater treatment as well as the development of environmental protection infrastructure. Reused water is primarily obtained from sources such as reverse osmosis concentrate, wastewater from cooling water systems, and water used for backwashing filters; after treatment, this water meets the required standards and is used as supplementary water for cooling water systems, thereby enabling annual savings of around 1 million cubic meters of raw water ； Treating pollution with pollution: the alcohol-ether wastewater from methanol plants is used in the biochemical treatment system, where it is added as a carbon source at the beginning of the anaerobic reaction stage ； During flue gas desulfurization maintenance, the recycled wash water is used to replenish water in the flue gas desulfurization system, thereby reducing the use of fresh water ； Significantly improve the capacity to treat domestic wastewater from production areas, docks, and residential areas, reduce the total amount of pollutants discharged, lower wastewater treatment costs, and alleviate the processing burden on the Naxi Wastewater Treatment Plant ； Strictly enforce, in accordance with the law, the water withdrawal permit system, the discharge outlet installation permit system, the discharge permit system, and the total pollutant emission control system ； Manage water resources in accordance with the law, protect them properly, conserve water, ensure safe drainage, make use of wastewater, and actively fulfill the responsibilities of an environmentally responsible and honest enterprise. The company adheres to the development concepts of \"giving priority to ecology and pursuing green development\" as well as \"lucid waters and lush mountains are invaluable assets,\" demonstrates a firm determination to control pollution in accordance with the law, strengthens efforts to reduce emissions at the source, implement monitoring during the production process, and carry out treatment at the end stage, ensures that wastewater treatment facilities operate at their maximum efficiency, and continues to work toward energy conservation, emission reduction, and the sustainable use of water resources ； Manage water resources in a meticulous, strict, and practical manner. The fragrance of plum blossoms comes from the bitter cold; achievements are not easy to attain, and more effort is needed in the future. The employees of Lutianhua will, with high spirits and great enthusiasm, go all out in efforts to reduce pollution and conserve water, so as to protect the city’s blue skies, clear waters, and happy living environment.
