Guardians of the "Ideal Coordinates" of Park City: Seeking Truth and Practicality of the First Reclaimed Water Plant in Tianfu New Area

In the first recycled water plant in Tianfu New District, the demonstration area of Park City, machine repair workers shuttle around every corner of the water plant all day, guarding every machine and equipment, silently dedicating their youth and passion to the ecological environment of Park City.

1、Unity

Mao Mingcai, an employee of the maintenance team, said, "As maintenance personnel, every small matter can affect the operation of the equipment, so we cannot 'hello, hello, everyone' and just muddle through. Sometimes we may argue fiercely over a small matter, but we can always tie a knot before a big one. We can all understand and understand each other."

Mao Mingcai's words are not only an interpretation of job responsibilities, but also a reflection of the spirit of teamwork. The experience of machine repair team leader Wang Qing has further elevated this spirit of unity. In 2023, Wang Qing suffered from a serious illness and upon his return, he discovered that everyone was rushing to do the physical labor of moving heavy objects. Although everyone said, "We want to develop 8 abdominal muscles to become a handsome man," Wang Qing knew very well that they were afraid of getting tired again. This spirit of mutual understanding and assistance has allowed them to grow together, not only improving work efficiency, but also making them an inseparable team.

2、Seeking Truth

Huang Gui, an employee of the maintenance team, said, "Although we often look down upon our positions in our work, we cannot underestimate them ourselves! Just like the screws on the equipment, we bear the great responsibility for the healthy operation of the water plant equipment, so everything must be taken seriously from the actual situation."

Once, there was a sudden malfunction of the push rod in the mud tank of the water plant. If it was replaced directly, although it was convenient and fast, it would cost nearly 30000 yuan. If this situation occurred in the future, it would cost a lot of money to repair. The investment in the water plant was too high, and after thinking about it, they decided, "Let's fix it ourselves!"

But how should we fix it? They consulted with the manufacturer, but received such a response: "We are all precision machine processing, and it is impossible for you to do it well manually, and it is time-consuming and laborious!"

The manufacturer's cold water did not dampen their enthusiasm, but instead stimulated the fighting spirit of these skilled technicians. Can't they just say it's not possible? The members of the maintenance team gathered together, leveraging their strengths and brainstorming, and slowly outlined a solution.

They directly purchased the parts they could buy in the market, and rolled up their sleeves to process the parts they couldn't buy. As a result, they only spent less than 6000 yuan to complete the replacement of the push rod, and also changed the original direction of the mud flow according to the actual situation of the water plant, increasing the mud flow speed by 33%, greatly saving equipment power consumption.

Through this process improvement, everyone has formed a consensus: as a truly valuable mechanic, we should not only maintain the operation of equipment by buying new and replacing old ones, but also achieve cost reduction and efficiency increase at the source by fully understanding operational needs and equipment characteristics, and through technological innovation without spending an extra penny.

This victory did not stop them. Subsequently, they turned their innovative focus to the dredging process in the pre-treatment area of the water plant. Due to the excessive impurities in the sludge, the desilting machine cannot be used directly and can only be cleaned using traditional suction methods, resulting in high costs. The maintenance team couldn't help but ponder, "Isn't there a cheap and efficient way?"

So, everyone once again demonstrated their wisdom and courage, while searching for various information online and reviewing the dredging process. By cleverly using existing equipment - a slag screening machine, they first screened for large impurities in the sludge, and then used a desilting machine. Finally, they successfully solved the problem, not only improving treatment efficiency, but also saving up to 40000 yuan in dredging costs for the water plant.

This series of innovative measures not only showcases the professional skills of the maintenance team, but also highlights their team spirit of daring to challenge, seeking truth and innovation. Under their efforts, the operational efficiency of the water plant has been significantly improved, while also setting an example for the industry to reduce costs and increase efficiency.

3、Pragmatism

Su Tianyong, an employee of the mechanical repair team, said, "Since I was young, my parents have told me to be down-to-earth in our work, and to be meticulous in our maintenance work step by step. Any negligence can cause big trouble, so we must be more attentive, use our brains more, and work diligently."

The dry mud transfer pump is an important equipment for sewage treatment, and its maintenance cost has always been high. On average, it needs to be replaced every 5 to 8 months, and the cost of each replacement is as high as over 20000 yuan. There is also no precedent in the market for optimizing dry mud conveying pumps. Faced with this challenge, the maintenance team did not choose to compromise, but was determined to find a solution.

"Since we couldn't 'feel the stones crossing the river', we thought of becoming 'stones' ourselves." Zhang Gen, an employee of the maintenance team, said, "At that time, our entire maintenance team was surrounded by the equipment and had heated discussions. Many times, everyone had a' red faced and red eared 'argument, but later we finally realized that the main problem was that the screw gap of the dry mud transfer pump was too large. When the mud and water mixed, the dry mud pump couldn't operate normally. So everyone finally decided to open an overflow tank on the collection hole of the transfer pump for drainage. Through this small change, we extended the service life of the equipment and could save nearly 10000 yuan in costs for the water plant in one year."

The staff of the maintenance team are not satisfied with this, they aspire to turn the equipment into a "hexagonal warrior" with comprehensive optimization of performance, cost, and service life. From improving the pneumatic system of the push rod of the sludge removal machine to extend its service life, to adjusting the operating frequency of the grid machine to reduce wear and tear... Small optimizations were born from their hands, and big efficiency improvements burst out from their minds.

Chen Jiujiang, the head of the factory operation team, praised their achievements, saying, "We usually use these equipment with ease and convenience, which is the pragmatic attitude of our mechanical repair colleagues. They strive for excellence in machinery, and through their technical maintenance and renovation, not only have operating costs been reduced, but also the equipment in the factory has never had major problems, with a completeness rate of over 98%."

Repair the mud pump

The employees of the machine repair team, with a spirit of craftsmanship and a pragmatic attitude, adhere to their "small positions" in the daily work of the sewage treatment plant, not lose standards due to ordinary work, and not give up requirements due to boring work. They have contributed their "great energy" to the water environment treatment of the "demonstration area" of the park city.
