Carborundum filter material cleaning and regenerating process

Abstract

The invention relates to the technical field of carborundum recycling, and discloses a carborundum filter material cleaning regeneration process, which specifically comprises the following steps: S1, preparation: putting 16% of nonylphenol ether, 9% of fatty alcohol ether, 7.5% of sodium nitrilotriacetate, 5% of triethanolamine, 9% of sodium alkyl benzene sulfonate, 12% of sodium bicarbonate, 4.5% of sodium hydroxide and 37% of water into a stirrer, and stirring to obtain a cleaning agent; s2, washing: guiding the carborundum filter material into a stirrer, adding 2 times of water, adding into the prepared cleaning machine, and then heating the stirrer. According to the carborundum filter material cleaning and regenerating process, crude oil, mechanical impurities and sulfides on the surface of carborundum are cleaned through hot water, impurities on the surface of carborundum are removed, then the carborundum is cleaned again under washing of water flow through a cleaning agent, the impurity removal rate is further increased, pollution is low, and the on-site environment can be maintained.

Description

technical field [0001] The invention relates to the technical field of carborundum recovery and utilization, in particular to a carborundum filter material cleaning and regeneration process. Background technique [0002] With the deepening of oilfield development, the treatment of oil production wastewater has become one of the important tasks of oilfield water injection development. Oilfield exploitation will generate a large amount of oil production wastewater and ground process operation wastewater, which need to be treated and recycled, most of which are reinjected into the formation , Reinjection water quality requirements are very high, and water quality that does not meet the standard will directly affect the effect of oilfield development. At present, oilfield sewage treatment stations generally use demulsification and sedimentation first, oil-water separation, and then use sewage filter tanks to filter and separate crude oil and other suspended substances in the sewa...

[0002] With the deepening of oilfield development, the treatment of oil production wastewater has become one of the important tasks of oilfield water injection development. Oilfield exploitation will generate a large amount of oil production wastewater and ground process operation wastewater, which need to be treated and recycled, most of which are reinjected into the formation , Reinjection water quality requirements are very high, and water quality that does not meet the standard will directly affect the effect of oilfield development. At present, oilfield sewage treatment stations generally use demulsification and sedimentation first, oil-water separation, and then use sewage filter tanks to filter and separate crude oil and other suspended substances in the sewage. The commonly used filter materials for oil field sewage filter tanks include magnetite, quartz sand, gravel, manganese sand and other mineral series filter materials and organic filter materials such as walnut shell powder and fiber balls. When the effect of conventional treatment methods is limited, the filter material needs to be replaced
