Description
Technical field
The present invention relates to a kind of sullage solidifying method and mixing plant.
Background technology
Solidification is the major way that rarefaction wave reuse of dredging is utilized, but can be more serious when the content of organic matter is higher in dredging silt
Its solidification effect is influenceed, therefore proposes to carry out dredging silt pre-treatment using alcoholic solution to reduce its content of organic matter, from
And improve its curing performance.
Now retrieve in Chinese Society of Hydraulic Engineers's Annual Conference paper, have one by bavin morning sunlight, Yang Guolu, the same official of Liu, Wang Qian
The theme delivered jointly is a kind of paper for the method for improving dredging silt curing performance, and there is illustrated remove to become silted up by alcohol
The method of organic matter in mud；
Mud need to be air-dried, be packed after ground mesh sieve for alcohol reaction, remove the organic matter in mud, this method is excellent
Point is simple and environmental pollution is few in operation.
But, because organic content is differed in the mud at each edge of lakebed, the body of the mud of Unit Weight to alcohol
Amount requires different；In the case where alcohol reaction container is certain, different silts are blended according to same ratio alcohol
Mud, can be because alcohol excessively make unnecessary alcohol volatilization allow expense for the relatively low mud of the content of organic matter.
The content of the invention
The first object of the present invention is to provide a kind of sullage solidifying method, is mixed by agitating paddle mud, reaches list
The content of organic matter in the volume mud of position, improves the utilization rate of ethanol postincubation.
The present invention above-mentioned technical purpose technical scheme is that：
A kind of sullage solidifying method, the first step：The detection of the content of organic matter is carried out to the mud taken along river-bed section, by organic matter
Content carries out the classification designator of mud；
Second step：The mud of classification designator is carried out to the mixing of mud by the inverse proportion of organic content from small to large, and by stirring
Mixing equipment is revolved round the sun using agitating paddle and is stirred with the mode of autobiography；
3rd step：Mud after stirring is air-dried successively, screened, the sludge granules after screening are put into alcoholic solution and carried out
Mixing；
4th step：Mud after being volatilized to alcoholic solution is mixing cured with curing agent, is then conserved.
By using above-mentioned technical proposal, by detection, the content of organic matter in a water bed mud, decision method are first judged
It can use by sampling mud, then determine the content of organic matter in mud sample with potassium dichromate oxidation Outside Heating Method；
Classification designator, is conducive to later stage mud mixed processing；The vessel size of alcohol reaction is limited, if that places all has
The higher mud of machine matter content, it is most likely that occur, alcohol is filled it up with vessel, and to be also difficult to meet high content in such mud organic
The reaction of matter；
Fed intake according to content of organic matter inverse ratio so that the mixed content for having organic matter in cubic unit mud controls 6%-
30%, it is easy to the abundant reaction of later stage alcohol and mud.
Using agitating mode of the revolution with autobiography, the significantly more efficient organic matter by each classification is mixed.
It is to reduce influence of the moisture to alcohol Capacity Ratio in alcoholic solution in mud using air-dried purpose so that prepare
Alcoholic solution can more accurately according to hybrid reaction require carry out remove organic matter reaction.
The purpose of screening is to remove some large granular impurities, reaction of the reduction impurity to organic matter and alcohol；
Mud is solidified by curing agent and after conserving, new mud has stronger structural strength.
Preferably, being provided with back and forth the broken arch bar on upper top in second step, mixing plant, broken arch bar promotes mud to stirring
At oar.
By using above-mentioned technical proposal, agitating paddle is stirred in the way of revolving round the sun and coordinating with autobiography, is stirred with raising
Oar swept area is mixed, the effect of stirring efficiency is improved.
Preferably, in the 3rd step, alcohol concentration uses 41% in alcoholic solution, and the liquid-solid ratio example of alcoholic solution and mud is adopted
With 54：1.
By using above-mentioned technical proposal, pass through single factor experiment：Obtaining ethanol postincubation optimum condition is：Processing time 47
Minute, alcohol concentration 41%, liquid-solid ratio 54：1, corresponding organic removal rate is 51.1%.
Preferably, in the 3rd step, particle is selected using 100 mesh sieves to air-dried rear mud.
By using above-mentioned technical proposal, 100 mesh sieves select particle, when the mud and alcohol reaction of the granular size most
To be quick, abundant.
The second object of the present invention is to provide a kind of mixing plant, reaches that the effect of uniform mixing mud reaches unit volume
The content of organic matter in mud, improves the utilization rate of ethanol postincubation.
