Problems solved by technology

For example, the incineration method consumes a lot of energy, is prone to secondary pollution, and oil resources have not been recycled; the problems of the solvent extraction method are that the process is long, the process is complicated, and the treatment cost is high. It is only suitable for oily sludge containing a large amount of refractory organic matter. ;Chemical demulsification method needs to add demulsifier and heating to oily sludge with severe emulsification

Abstract

The invention relates to the technical field of oily sludge treatment, in particular to an oily sludge treatment process method through a biological method. The method comprises the following steps: S1, separating oil, water and solid residues; and S2, treating the solid residues by adopting a biological treatment method. The process disclosed by the invention integrates the advantages of a thermal washing method and a thermal decomposition method, effectively overcomes the defects of the thermal washing method and the thermal decomposition method, can turn waste into wealth, can be used for high-strength organic and solid load conditions including odor control of faeces lagoon and compost, BOD5 emission reduction and sludge reduction, adopts the biological method for oily sludge treatment, is low in treatment cost, and low in energy consumption, has remarkable cost advantage, has simple operation and lasting effect, does not cause secondary pollution of atmosphere, sewage and the like, and realizes maximum resource recovery and harmless up-to-standard discharge.

Description

technical field [0001] The invention relates to the technical field of oily sludge treatment, in particular to a biological oily sludge treatment process. Background technique [0002] Oily sludge is an accompaniment to oil production, one of the main pollution sources of oil production, and a major problem affecting the quality of oil fields and surrounding environments. There is a large amount of organic matter and rich nitrogen, phosphorus, sulfur and other nutrients in oily sludge. If the sludge without stabilization treatment is discharged into the water body at will, the organic matter and ammonia nitrogen in the sludge will consume a large amount of oxygen in the water body and cause the water quality to deteriorate. Seriously affect the survival of aquatic organisms, nutrients will make the water eutrophication, causing red tides and green tides in coastal waters. In addition, oily sludge with different components has different hazards to the environment and human b...
