Abstract
Treatment for curing silicon-free sludge and condensed oil sewage is carried out by adding cement 30-70wt%, sand 10-30wt%, reinforcer 1-5wt% and water into agitator, adding into silicon-free sludge 10-40wt%, agitating in agitator, forming in mould, curing for 3-7daysm de-moulding, maintaining for 7-15days and curing. It's simple, convenient and cheap and has no secondary pollution.
Description
Technical field:
The present invention relates to a kind of solidification processing method of removing silicon from thick oil sewage mud.Specifically by with removing silicon from thick oil sewage mud with after cement, sand, toughener mix, solidify, can make cured block with higher-strength, the cured block of gained can be used as ornamental slab for paving the floor, curb etc., can make the silica removal recycling sludge, elimination is to the pollution of environment.
Background technology:
What at present, removing silicon from thick oil sewage produced is more unmanageable problem except that silicon sludge in a large number.For sludge treatment, Chinese patent CN1382652A discloses a kind of quick, economic sludge treatment technique.It is to burn after mud granulizing, the oven dry, can handle continuously the mud that sewage work produces.This processing mode is suitable for the processing of various organic sludges but long flow path, and processing cost is higher.Chinese patent CN1105689C, CN1178777A reclaim the part oil product in the oily sludge by with oily sludge stripping, distillation.This processing mode is suitable for petrochemical complex and the scum silica frost of sewage from oil refinery treating processes generation and the technology of oily sludge.CN1579969A then by add hot water, stirring in oily sludge, realizes the separation of profit.It is suitable for the oil field and lands the processing of oil, jar bed mud and refinery greasy filth.Big and inorganic content is high removes silicon sludge and use aforesaid method and can't handle for generation.
Generally speaking, all there is following problem in aforesaid method:
1, treatment scheme is long, and cost is higher;
2, the suitable object of handling is that height contains organism and oily sludge;
3, processing is thorough inadequately, has the secondary pollution phenomenon.
Summary of the invention:
The present invention aims to provide a kind of non-silicon sludge curing treatment of thickened-oil sewage, is a kind of solidification processing method of removing silicon from thick oil sewage mud of simple, efficient, environmental protection.
For achieving the above object, the present invention take technical scheme be: in agitator, add cement, sand, remove silicon sludge, toughener and water, additional proportion is: the consumption of cement is 30%～70% of a gross weight, is preferably 40%, and the particle of sand is 1～3mm, dosage is 10%～30% of a gross weight, being preferably 20%, removing silicon sludge is 10%～40% of gross weight, is preferably 25%, and the toughener dosage is 1～5%, be preferably 3%, under agitation add the water of surplus then.After in agitator, mixing,, after the demoulding maintenance, its curing is got final product in die for molding.
Cement used in the invention can be 325
#Cement, 425
#Cement, superfine cement, its dosage is 30%～70% of a gross weight, is preferably 40%; Used sand is quartz sand, crushed-gravel, and the particle of sand is 1～3mm, and dosage is 10%～30% of a gross weight, is preferably 20%.Used toughener is cyanamide resin, Resins, epoxy or urea-formaldehyde resin.Its dosage is 1～5% of a gross weight, is preferably 3%.Used remove silicon sludge moisture to be 20～70%, to be preferably 30%～40%, dosage be gross weight 10%～40%, be preferably 25%.Used mould is: ornamental slab for paving the floor mould or curb mould.
Compared with prior art, the present invention has following useful effect:
1, treatment process is simple, and is easy to operate;
2, processing cost is low, and Pollutant Treatment is thorough;
3, big to the treatment capacity of removing silicon sludge, do not produce secondary pollution after handling;
4, remove silicon sludge through after the solidification treatment, can realize removing the resource utilization of silicon sludge.
