Abstract
The present invention relates to method for sludge treatment, particularly relate to the deep treatment method of a kind of excess sludge.The present invention provides the deep treatment method of a kind of excess sludge, comprises the following steps: step A: mud is presetting；Step B: mud is carried out pretreatment with organic solvent；Step C: mud is carried out microwave treatment；Step D: pretreated excess sludge is carried out under room temperature condition natural drying or vacuum filtration.The present invention by carrying out mixing preparation to reach suitable mud solid content scope by the excess sludge of the dewatered sludge of high solids Yu low solid content, and it can significantly reduce the processing load of follow-up mud, improves Treatment of Sludge efficiency.
Description
Technical field
The present invention relates to method for sludge treatment, particularly relate to the deep treatment method of a kind of excess sludge.
Background technology
Mud is the end product of sewage disposal, and pollutant concentration degree is high, and comparison of ingredients is complicated, and the content of organic matter is high, parent
Aqueous is strong, and specific surface area is big, and dehydration difficulty is big, and mechanical dehydration efficiency is low.At present, the mud of municipal sewage plant of China has
More than 80% is effectively disposed.Mud is adjusted by major part sewage treatment plant simply by adding chemical agent (PAM etc.)
Matter carries out mechanical dehydration again, but uses merely chemical agent can only improve the dewatering speed of mud, it is impossible to improve degree of dehydration,
The moisture content of final mud is still up to 80%.This dewatered sludge remains as solid-liquid admixture, pasty state, is not easy to conveying
And stacking；Volume is the most relatively bulky, and content of organics is high, easily corrupt, has had a strong impact on follow-up sludge treatment；And exist each
Planting pathogenic bacterium and parasitic ovum, in partial sludge, content of beary metal exceeds standard, and easily causes environmental pollution, threatens ecological balance.
Summary of the invention
For defect or deficiency present in prior art, the technical problem to be solved is: provide one surplus
The deep treatment method of remaining mud, it can significantly improve the solid content of mud, it is achieved the minimizing of mud, stabilisation, harmless
Change and resource.
To achieve these goals, the technical scheme that the present invention takes is to provide the advanced treating side of a kind of excess sludge
Method, comprises the following steps:
Step A: mud is presetting；
Step B: mud is carried out pretreatment with organic solvent；
Step C: mud is carried out microwave treatment；
Step D: pretreated excess sludge is carried out under room temperature condition natural drying or vacuum filtration.
As a further improvement on the present invention, described organic solvent formaldehyde, acetone, ethanol.
As a further improvement on the present invention, described mud is containing clarifier sludge and preliminary hydro-extraction mud.
The invention has the beneficial effects as follows: the present invention is by the excess sludge by the dewatered sludge of high solids Yu low solid content
Carrying out mixing preparation to reach suitable mud solid content scope, it can significantly reduce the processing load of follow-up mud, improves
Treatment of Sludge efficiency.
Detailed description of the invention
Below in conjunction with explanation and detailed description of the invention the present invention is further described.
The present invention provides the deep treatment method of a kind of excess sludge, comprises the following steps:
Step A: mud is presetting；
Step B: mud is carried out pretreatment with organic solvent；
Step C: mud is carried out microwave treatment；
Step D: pretreated excess sludge is carried out under room temperature condition natural drying or vacuum filtration.
Described organic solvent formaldehyde, acetone, ethanol.
Described mud is containing clarifier sludge and preliminary hydro-extraction mud.
Above content is to combine concrete preferred implementation further description made for the present invention, it is impossible to assert
Being embodied as of the present invention is confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of present inventive concept, it is also possible to make some simple deduction or replace, all should be considered as belonging to the present invention's
Protection domain.
