Henan Oilfield Refined Wax Factory Strengthens Wastewater Management

Since the beginning of this year, Henan Oilfield Refined Wax Factory has stepped up its wastewater management, and the total COD and ammonia nitrogen indicators of the company's total drainage have continued to decline. At the end of April, the total COD of the whole plant was 60 mg/l, and the ammonia nitrogen content was 3 mg/l, which was far below the national environmental requirements of COD of 150 mg/l and ammonia nitrogen of 10 mg/l.

As an enterprise located in the headwaters of the Huaihe River, refined wax plants put safety and environmental protection work at the top of the list. By strengthening source control, strengthening internal management, optimizing processes, and fine operations, the environmental protection work has achieved remarkable results. The plant has intensified inspections and carefully monitored the water quality of each installation. Once the water quality is found to be abnormal and the water volume fluctuates significantly, adjustments are made immediately, and in the future, the water is introduced into the standby accident tank and the water quality is gradually processed. To ensure that the sewage reaches the standard discharge. From January to April, the qualified rate of waste water discharged from the plant was 100%.

At the same time, the plant continuously optimizes its processes and improves its sewage treatment capacity. Through serious research and analysis, the technicians optimized the process of the two 3000 cubic meters of septic tanks that were originally used in parallel, and changed them into tandem use, which greatly improved the ability to regulate water quality.

The plant also improved the environmental risk plan, and implemented water body pollution prevention and control measures such as furfural tank area water pollution evacuation process reform test and emergency cut-off of wastewater from storm drains, etc., in order to improve the overall plant wastewater. The ability to deal with risk.
