Thread Content

Work Summary: 2017 is coming to an end. Throughout this extraordinary year, the wastewater treatment workshop, under the proper leadership of the company’s management team and with the support of other workshops, focused on production and operations as its core task, worked hard to complete various tasks successfully, achieved certain results, and thus contributed significantly to the healthy and steady development of the company. 1. The main task of the safety-production sewage workshop is to receive sewage from other workshops. In line with the production targets and key performance indicators set by the company at the beginning of the year, all employees in the wastewater treatment plant worked together hard in 2017 to continuously improve their performance, achieving these goals and ensuring the safe operation of the production facilities. During normal operation, the wastewater treatment plant receives around 70 cubic meters of wastewater per day. It carries out safety management tasks as instructed by management, and treats the wastewater to meet the required discharge standards ； During the downtime period, emphasis should be placed on workshop safety, proper equipment maintenance, and employee training, so as to be fully prepared for resuming operations at any time. II. Energy Conservation and Consumption Reduction The company has always attached great importance to energy conservation and consumption reduction. In 2017, the board of directors urged the company to step up its efforts in this area. The wastewater treatment plant took into account its own circumstances as well as the specific conditions of its operation, and carried out thorough work to achieve energy conservation and consumption reduction. To better meet the above requirements, all employees in the workshop worked together to earnestly implement energy-saving and consumption-reduction measures, taking various approaches that yielded significant results. The main points are as follows: (1) Reducing electricity costs. Through a summary of the wastewater treatment process and an analysis of the motor power of the plant equipment, and given that the power of the aeration fan is 22 KW, the usage methods for this fan during operation and downtime were determined. While ensuring the quality of the produced water and maintaining the activity of the activated sludge, the aeration fan is now operated intermittently for 10 hours per day instead of 24 hours continuously. Just for this aeration fan alone, around 9,000 kWh of electricity can be saved per month; adding in the reflux pumps for the anaerobic tank and the wastewater reflux pump, approximately 10,000 kWh can be saved per month. (II) Optimize the combination of additives used in wastewater treatment to reduce additive costs. By adding coagulants and using them in a scientific and rational combination with flocculants, it is possible to **reduce the amount of flocculant required**, without affecting the operation of wastewater treatment equipment or the quality of the treated water. During the shutdown period, in order to maintain the activity of the activated sludge, industrial glucose needs to be added. By adjusting the treatment of the activated sludge and determining the appropriate timing and amount of glucose addition, it is possible to save about half a ton of glucose per month. (III) Reuse of qualified wastewater. Under the guidance of company leadership, reuse standards were established for water from other devices; the wastewater entering the sewage treatment plant was processed into recycled water and fire-fighting water, which not only reduced external drainage costs but also saved tap water. (IV) Treated tank farm wastewater. Upon receiving the order from management to have the wastewater from the tank area treated by the wastewater treatment plant, samples were taken for analysis immediately. It was determined that this wastewater is highly alkaline and contains sulfides, ammonia nitrogen, and high levels of COD. Since the amounts of surfactants as well as benzene and phenol compounds in it are unknown, and sulfides can produce substances such as hydrogen sulfide during oxidation-reduction processes, all of which are highly toxic to organisms, the existing wastewater treatment system in this plant is not capable of treating this wastewater immediately. Under the guidance of senior management, the wastewater treatment plan was finalized and implemented accordingly; the wastewater from the rear tank area was successfully treated, completing the task. This approach saved approximately 700,000 yuan in costs by avoiding third-party treatment services. III. Workshop Management: In February 2017, after the new leadership took office, they made some revisions to the existing systems. I feel that these changes were made with the well-being of Huasheng’s employees in mind, reflecting a truly people-oriented approach to company management, which earned them high praise from the employees. In workshop management, the main tasks I completed as per the company’s instructions were: 1. Installing protective covers on the Fenton system and water collection tanks. 2. Re-count the old and new equipment in the wastewater treatment workshop and establish records. 3. Conduct proper training by providing safety and operational training to both new and existing employees, so that operators can quickly gain an understanding of the new sewage treatment equipment and its principles, meeting the requirements for taking up their duties. 4. Improve the workshop regulations by revising the job responsibilities within the workshop, as well as the systems for routine inspections, shift handovers, leave applications, and hazard identification. Establish and maintain proper records for equipment maintenance, the upkeep of fire protection facilities, and the maintenance of emergency rescue equipment. 5. Develop a maintenance plan for the wastewater treatment workshop, and carry out equipment maintenance in accordance with this plan. 6. Cooperate with the construction team to complete the relocation of the online sewage monitoring equipment. 7. Assist the company in preparing the materials needed for revalidation. 8. Assist in the organization of documents related to the four systems, four ratings, and one assessment as part of the work. IV. Maintenance and technical upgrades: During the period when work was not carried out in 2017, the management instructed that maintenance of the equipment in the workshop be done properly. To ensure that maintenance work is completed on time and to the required standard, our workshop takes action in the following areas. First, it is necessary to carry out thorough preparatory work before maintenance; each team shall report the problems that have arisen during equipment operation as well as the items that require maintenance. The workshop then aggregates this information, and after review by various parties, determines the scope of the maintenance work, while also submitting the materials required for it. Second, during maintenance work, tasks are divided and carried out simultaneously by different personnel, with dedicated staff in charge to ensure the schedule is met and the quality of the maintenance is maintained. Third, after the maintenance is completed, a centralized inspection and acceptance are carried out in the workshop to prevent any overlooked items or other potential hazards, ensuring the normal resumption of production. After half a year of operation, it was found that the sewage treatment equipment and processes were somewhat impractical. In light of this, a plan for technical upgrades to the equipment was included in the maintenance plan. The main technical improvement involved adding air supply systems for stirring in the oil separation and regulation tank, which prevented the difficulties that would arise from cleaning the tank in the future ； Add a cross-line for the sump lift pump and sludge pump, thereby providing an additional backup pump to prevent disruptions in operations due to equipment failure ； Protective covers have been added to all pump motors to prevent equipment damage caused by rain. V. Existing shortcomings and future directions for improvement (1) Internal management is not detailed enough. Compared to the second half of 2016, management improved slightly in 2017; however, overall workshop management remains inadequate, with many issues still existing. Various systems need further improvement and supplementation, and there are delays or slowness in management tasks, sometimes resulting in a passive approach. This is manifested in two ways: first, there is inadequate management of the equipment; sometimes regular inspections are not carried out, and there are no timely rewards or penalties for such inspections, resulting in insufficient enforcement. Second, the education of employees’ mindset is inadequate, resulting in their work enthusiasm not being fully utilized. Third, the revision of regulations is not timely enough, and enforcement is insufficient; there are instances of violations of labor discipline, which will be one of the key focuses in future work. (II) The overall technical level of the workshop needs further improvement. Through various forms of technical training and knowledge exchange, the technical skills of the workshop employees have improved, but there is still a gap compared to the requirements set by the workshop and the company. In particular, when it comes to handling emergency situations, there is a lack of technical support. Therefore, in the new year, it is still necessary to enhance the employees’ technical skills so that they can better meet the demands of the company’s development. (III) Insufficient effort is being put into implementing energy-saving and consumption-reduction measures as well as low-cost control strategies. In 2017, in accordance with the company’s relevant requirements, the workshop strictly implemented various control metrics and made significant efforts in energy conservation and consumption reduction, achieving notable results. However, there is still a gap compared to the company’s development goals and requirements; it is necessary to further tap potential, identify shortcomings, strengthen employees’ awareness of energy conservation in all aspects, and ensure that efforts to save energy and reduce consumption are put into practice. In short, by mid-2017, despite our extensive and effective efforts and the achievements we made, there was still a significant gap compared to the requirements set by leadership and when compared with other affiliated units. In the new year, we will surely implement the company’s various decisions with even greater diligence. Focusing on the core of the enterprise’s production and operations as well as the company’s key tasks, we will carefully identify any shortcomings in our work. By uniting and leading all the staff in the workshop, we will work diligently, with dedication and professionalism, to build on our achievements, address our weaknesses, and learn from others. With improved performance, we will make our due contribution to promoting the healthy and rapid development of the company. Sewage Treatment Plant, December 12, 2017
