Yunnan Jianfeng Cement Company is located in the southwestern part of the Yunnan-Guizhou Plateau. Water resources are mainly supplied by precipitation. Although the total amount of rainfall is relatively abundant, because the area is mostly mountainous, water resources development is difficult and the time distribution is extremely uneven. The contradiction between supply and demand is prominent. In particular, in 2019 , Pu 'er City experienced the heaviest period of meteorological drought days in the same period since meteorological records were made. The average total drought days exceeded 200 days, and the storage capacity of Dazhong River Reservoir, the peak water intake point in Yunnan, was low and tight. In response to this situation, Yunnan Jianfeng has been attaching importance to water-saving work in recent years, and has established a water-saving work leading group with the general manager as the team leader and the managers of various departments as the team members to study and deploy the company's internal water-saving work. Through several years of efforts, Yunnan peak water conservation work has achieved initial results.

Strengthen Publicity and Standardize Management to Make Water Saving a Daily Day for Employees

In order to enhance employees' awareness of water saving, Yunnan Peak has actively organized water saving publicity activities in recent years by taking advantage of opportunities such as "World Water Day " and China Water Week ". By posting pictorial newspapers, distributing water conservation brochures, popularizing water-saving knowledge, and popularizing water-saving tips, each employee is allowed to actively participate in water-saving work, forming the greatest synergy of water-saving work and enhancing employees' awareness of water-saving; Rewards and punishments for water conservation have also been formulated to reward and punish water conservation and waste. At present, employees have basically developed a good habit of saving water.

Standardize measurement, establish ledgers, and make sure that you have a good idea of water use

Yunnan Peak will set up full-time water-saving personnel to uniformly manage the company's raw water pretreatment, raw water supply, measurement, and daily management and maintenance work, and be responsible for the regular verification of measuring instruments. According to "Water Metering Assessment Management System " , water metering management is implemented. A total of 3 primary water meters and 9 secondary water meters are installed. A water metering network diagram is established to form a basis for assessment management, laying a foundation for the implementation of daily water quota decomposition, and at the same time ensuring real-time monitoring and feedback of running, emitting, dripping and leaking. In order to make the water-saving work more practical and detailed, the water-saving management department decomposes the annual water consumption index into the daily water consumption, decomposes the daily water consumption into each key water consumption part, and establishes a water consumption account. The meter reader regularly analyzes the ledger, finds that the water consumption exceeds the standard, and reports it to the water saving team. The water-saving team timely analyzed the reasons for the excessive water consumption, and found out the water-saving methods as far as possible for those who did increase the water consumption due to the needs of business development. The waste of water resources caused by illegal water use or work omission shall be punished accordingly, so as to fundamentally put an end to the phenomenon of man-made waste of water.

adopts water-saving technology and uses water-saving equipment to promote the recycling of water resources

The hardness of circulating water in the waste heat power generation system of Yunnan Jianfeng Plant increases due to evaporation, and produces about 3 cubic meters of sewage every year. For this reason, Yunnan Jianfeng invested nearly 20 yuan to re-lay a special pipe network, and treated the sewage with high hardness for mine greening, truck washing, limestone crushing and spraying, etc. At the same time, the reclaimed water treated by the rainwater collection tank and sewage treatment station in the factory area is used for watering the roads and sites in the factory area. With the above two measures alone, Yunnan peak can save 3.5 cubic meters of water resources per year, and 2.5 yuan / cubic meters can save 8.75 yuan per year.

In addition, Yunnan Jianfeng has also actively carried out water-saving technological transformation, investing yuan to transform the automatic induction car washing device. By precipitating the car washing water, most of the water can be reused. Adhere to the use of high-efficiency water-saving water appliances, canteen, central control building and office building renovation of new urine flush valve 6 , toilet flush tank 13 , toilet flush valve 28 , quick-opening faucet 51 , flower bed greening water-saving nozzle 471 , effectively improving the utilization rate of water. In

2019 , Yunnan Jianfeng was rated as a water-saving enterprise by Yunnan Provincial Department of Industry and Information Technology. Taking this as an opportunity, the company further "Tighten Faucet " to promote the transformation of water use mode from extensive to intensive conservation. In 2020 , Yunnan Province took the lead in implementing the construction of water-saving enterprises in building materials industry to meet the standards and promote full coverage of water-saving work, the conservation and protection of water resources will be pushed to a new height of enterprise construction, and efforts will be made to realize the transformation from "to " to "to " .
