Summary of Upgrading Technology of Refining and Chemical Effluent Quality
In this paper,combined with the actual operating conditions and existing problems of the sewage treatment plant of refining and chemical enterprises,the main contents of the upgrading and upgrading of the total sewage discharge water quality are discussed,and the technical characteristics of the advanced sewage treatment technology adopted in the transformation are mainly introduced.The results of industrial application show that the combined technology is advanced and reliable,and the removal efficiency of COD,ammonia nitrogen and total phosphorus in sewage is high.The total sewage level of COD is 10.92 mg/L,BOD is 2.9 mg/L,ammonia nitrogen is 0.14 mg/L,total nitrogen is 6.62 mg/L,total phosphorus is 0.13 mg/L,and petroleum is 0.83 mg/L.It fully meets the requirements of the Comprehensive Sewage Discharge Standard of the Yellow River Basin in Shaanxi Province(DB 61/224-2018),and has obvious environmental benefits.The annual COD emission reduction is 3 309.4 kg,ammonia nitrogen emission reduction is 4 142.4 kg,and suspended matter emission reduction is 57.6 kg,which has played a positive role in the improvement of the surrounding ecological environment and the water treatment of Luohe River.It has certain popularization and reference value in the comprehensive treatment of wastewater in domestic refining and chemical enterprises.
