In the second half of last year, Baling Petrochemical raised the sewage treatment assessment standard from the national level 2 to the national level, and took on the wastewater treatment and discharge water supply and drainage business department. In the case of three sets of device design capacities of 140 and 100 mg/l, respectively, Take measures to stabilize the operation of the device. The functional departments of the business unit strengthen coordination and source monitoring, implement up-and-down linkage, strictly control and stabilize the water inlet of the device, keep the influent COD concentration, pH, etc. of the device stable within a more balanced value, avoid the device from being impacted, and reasonably adjust the air volume of the device. Increase the concentration of activated sludge and enhance microbial activity. At the same time, technicians implemented minor changes to the device. Surface sedimentation tanks often have sludge compaction in the sedimentation tank, which causes poor mud drainage and affects the operation cycle of the equipment. Technicians connect the air ducts at the mud outlets, change the siphon and sludge to lift the sludge, and eliminate the sludge compaction phenomenon. The device operation cycle.
In order to ensure long-term and stable discharge of discharge standards, the Water Supply and Drainage Business Department has established a separation separator de-sliming test, a sewer pipe inspection, a cleaning study, and an effective treatment of cowhide gypsum clay for the complex sewage components and difficult sludge treatment. In addition, four special topics such as advanced wastewater treatment and compliance testing were conducted to study potential problems and seek out the best solutions to eliminate hidden dangers in time.
Increased pass rate of first-grade discharge of sewage from Baling Petrochemical
In the first five months of this year, the effluent COD (chemical oxygen demand) of the sewage treatment division of Baling Petrochemicals and Water Drainage Division was assessed at the national first-grade discharge standard of 60 mg/l, and the qualification rate reached 97.6%, which was better than the target value of 2%. The best level of history.
