Experimental Study on Chemical Waste Oil and Water Treatment
Due to the large amount of waste oil and water generated during the synthesis of ammonia and urea by coke oven gas in chemical enterprises,coupled with the upgrading and renovation of enterprise equipment,the amount of waste oil and water generated during the production process has also increased exponentially,resulting in the existing oil recovery equipment always operating at full load.To effectively reduce the treatment load of waste oil and water in the oil recovery unit,this article adopts centrifugal separation technology to pretreat oily wastewater,which is then treated by the oil recovery unit to reduce the oil recovery load.After the separation and treatment experiment of waste oil samples,it was found that for samples with different oil content in the imported oily wastewater of the centrifuge,after separation and treatment by the centrifuge,the net oil content at the outlet reached 30-50 mg/L,and the water content of the separated waste oil reached below 15%.The treatment effect was good and the oil removal effect could be achieved.
