January 20, Jiujiang Petrochemical Sewage Treatment Plant A / O, Qing pool Qingchi overhaul work completed 10 days in advance, and to achieve safety and environmental protection throughout the entire process controlled clean, not only eliminates the discharge of major pollutants affect the discharge standards, and Pool cost savings and sludge disposal costs accumulated more than 380 million.
Sewage treatment plant A / O (biological treatment of nitrogen and phosphorus removal process system) is an important environmental protection Jiujiang Petrochemical plant since its inception in 1993 has been running for 24 years, due to the system long life, aeration hose damage , Aging of packing, corrosion of packing support steel structure and many other problems have become increasingly prominent. Moreover, A / O and Lian Po pool have not cleaned up for many years and a large amount of siltation in the pond has seriously affected the discharge of water continuously and steadily discharged by the Company.
In order to eliminate potentially huge environmental risks, the Company seized the favorable opportunity of less rain in winter and started the A / O and overhaul clearing and overhauling work in an all-round way from December 1 last year.
In view of the unfavorable factors such as heavy workload, long time span, overhauling difficulty, high risk of environmental protection and environmental protection, unforeseen circumstances and many other factors involved in clean-up and overhaul, the Company thoroughly grasped the key points, difficulties and progress of the overrun clean-up work and seriously Analyze and evaluate, evaluate and optimize the Qingchi project in detail, do a good job of making the safety risk assessment of fine pool, implement the operational safety measures effectively, adjust and optimize the sludge transshipment process, repair and repair the cross-line and increase the temporary pipeline and carry out labor competition and other effective measures , Which greatly improved the efficiency of sludge transportation and disposal and laid a solid foundation for not accelerating the progress and quality of clear pond construction.
In order to ensure the stable operation of the sewage treatment plant during the Qingchi period, the company organized three teams including the coordination of the Qingchi site, the upstream control and safety inspection, the daily inspection of the sewage discharge of the upstream plant and the comprehensive adjustment of the system, and the construction plan for docking with the construction unit , Identify operational risks, implement safety measures, strengthen on-site management and control, and win valuable time for on-site operations to complete their tasks ahead of schedule.
With the concerted efforts of all parties, the overhaul and mud-cleaning work was completed in full compliance with the original plan 10 days ahead of schedule and the operation of the sewage treatment plant during the clean-up period was guaranteed and the effluent quality of the effluent discharged continuously and steadily.
