Above-mentioned S1 steps, sludge containing oil grinding is after biological degreasing agent oil removing, then press filtration, obtains unwashed oil removing
The step of grinding sludge, including step in detail below：
S11, quantitative sludge containing oil grinding is transported in oil removing reactive tank 2 from storage tank 1, while opening aerator
And heater, make solution temperature rise to 40 DEG C；Oil removing reaction after the completion of stop aeration, make grinding sludge staticly settle to
The bottom of oil removing reactive tank 2；
After the completion of S12, sludge settling to be ground, bottom land grinding sludge is delivered to into filter press 9, to grinding sludge press filtration,
Obtain unwashed except oil grinding sludge, and the reactant liquor of extrusion is back in oil removing reactive tank 2.
The S2 steps, it is unwashed except oil grinding sludge is after cleaning, cleaned except oil grinding sludge
Step, it is specific as follows：
It is unwashed except oil grinding sludge is put into after the first rinse bath 3, the aerator of the first rinse bath 3 is opened, and is made
It is unwashed except oil grinding sludge is well mixed with water, it is to unwashed except oil grinding sludge is fully cleaned, to be cleaned complete
Into rear stopping aeration, make cleaning once except oil grinding sludge settling is to bottom land；Cleaning once except oil grinding sludge settling it is complete
The second rinse bath 4 is delivered to after complete, the aerator of the second rinse bath 4 is opened, make cleaning once except oil grinding sludge and clear
Scouring water is fully contacted, to cleaning once carry out fully cleaning again except oil grinding sludge, it is to be cleaned after the completion of continue aeration,
Cleaned except oil grinding sludge.
S3 steps, cleaned except oil grinding sludge is after magnetic separation, obtain utility and harmless grinding dirty
The step of mud, specifically cleaning, terminate rear aeration pump and work on, while magnet separator 1111 is opened, by the second rinse bath 4
In except oil grinding sludge absorption and be sent to recovery storage tank 5 in.
During utilization, 6 timing of chemicals dosing plant supplements medicament needed for oil removing reactive tank 2.
Above-mentioned a kind of recycling processing method containing oil grinding sludge, by biological degreasing agent useless in grinding sludge
Mineral oil is removed, and waste mineral oil is transferred in liquid, and waste mineral oil is decomposed into harmless by microorganism in biological degreasing agent again
Small-molecule substance, prevents greasy dirt in the enrichment of oil removing reactive tank 2.Due to the degradation of microorganism, enable degreaser long
Time maintains the effect of efficient degreasing, while avoiding the frequent discharge of oil removing waste water, decreases secondary in processing procedure
Pollution；Low-cost processes sludge containing oil grinding is realized, the secondary pollution in processing procedure is reduced, and is reclaimed sludge containing oil grinding
In utility, reduce the wasting of resources.
It is above-mentioned only with embodiment further illustrating the technology contents of the present invention, be easier to understand in order to reader, but not
Represent embodiments of the present invention and be only limitted to this, it is any to extend or recreate according to the technology done by the present invention, by the present invention's
