Abstract
A kind of drilled pile waste mud secondary hardening solid-liquid separation treatment method, step are：S1 precipitates discarded slurry introducing sedimentation basin, and the landwaste for being deposited in lower part directly throws aside spoil disposal area；Discarded slurry after precipitation removes rock slag is introduced buffer pool by S2, and water is added to add de- steady medicament, carries out breaking steady processing, buffering sedimentation early period；S3 will break steady integrated apparatus by breaking the discarded slurry surely handled input sludge early period, add in take off steady medicament again, the secondary broken steady processing of progress, and force realization separation of solid and liquid by force (forcing) pump；The dehydrated sludge that S4 is isolated is discharged through sludge conveyer, and desiccation forms mud cake；The sewage isolated can be recycled or be discharged into sewage-treatment plant, rear direct emission up to standard.Treatment method avoids discarded slurry direct emission and occupies storage area, water and mud separation is realized, consequently facilitating water and mud secondary use.
Description
Technical field
The present invention relates to technical field of bridge construction, more particularly to a kind of brill used during grand bridge drilling construction
Hole stake discarded slurry secondary hardening solid-liquid separation treatment method.
Background technology
Field Huan's railway is located at Benxi county in environment protecting travel area and Huan Ren counties, there is 5 (Tian Shifu grand bridges of grand bridge
1283.9 meters, thank 1873.7 meters of a river bend and mountain recess grand bridge, 1307.5 meters of the grand bridge in little Yao ridges 1, the sub- grand bridge 1222.5 in three rivers
Rice, 1959.7 meters of ginger man fort grand bridge), in drilled pile deep foundation drilling, all places discarded slurry in generation, if do not handled
Direct emission generates ill-effect to soil, water system, vegetation, jeopardizes ecology, tourist environment, serious contaminated matter is caused to river
Therefore it certainly will be recorded gross misconduct by local responsible institution significant fine, influence corporate reputation.
Previous processing scheme is to go along with sb. to guard him storage using expropriation of land block of digging pit, but discarded slurry is a kind of special colloid-stabilised
System, can stable for extended periods of time state, after standing time length, except top air-dries peeling, lower part will the several years can to many decades
It is absolutely dry.Not only storage pond takes up a large area, and wastes land resource, and have high salt concentration, heavy metal, organic matter etc. to have in mud
Malicious ingredient pollutes environment.
Invention content
The present invention provides one kind for technical problem present in solution known technology and avoids direct emission and occupy to store
Area realizes water and mud separation, consequently facilitating the drilled pile waste mud secondary hardening solid-liquid separation treatment side that water and mud utilize
Method.
The present invention is adopted the technical scheme that solve technical problem present in known technology：
A kind of drilled pile waste mud secondary hardening solid-liquid separation treatment method, which is characterized in that including following processing step
Suddenly：
S1 precipitates discarded slurry introducing sedimentation basin, and the landwaste for being deposited in lower part directly throws aside spoil disposal area；
Discarded slurry after precipitation removes rock slag is introduced buffer pool by S2, by 1：1 ratio adds water agitation and dilution, and adds
Enter de- steady medicament, carry out breaking steady processing, buffering sedimentation early period；
S3 will break steady integrated apparatus by sludge pump by breaking the discarded slurry surely handled input sludge early period, add again
Enter de- steady medicament, carry out secondary broken steady processing, and separation of solid and liquid is realized by force (forcing) pump pressure；
The dehydrated sludge that S4 is isolated is discharged through sludge conveyer, and desiccation forms mud cake, and mud cake can be used as side slope protection
Planting soil, Dumping Sites are reclaimed or ground is made in river shoal；The sewage isolated can be recycled, first, being introduced into the buffer pool in S2, use
Discarded slurry is diluted, second is that for dissolving the de- steady medicament to be added in S2 and/or S3；Or the sewage isolated is discharged into dirt
Water treatment facilities, rear direct emission up to standard.
Further：The de- steady medicament used in S2 and S3 is two kinds, takes off steady medicament and uses cationic polyacrylamide
And aluminium polychloride.
The present invention has the advantage that and good effect：
This drilled pile waste mud secondary hardening solid-liquid separation treatment method, by secondary broken steady processing, realize water and
The separation of mud；The water isolated can be used in step 2 and step 3, is used for so as to save processing, water also can be through sewage disposal
Afterwards, direct emission；And the mud cake for isolating generation can be used as the planting soil of side slope protection, Dumping Sites are reclaimed or river shoal makes with making
With in this way, it is avoided that direct emission and occupancy storage area, realizing turns waste into wealth.
Description of the drawings
Fig. 1 is the process flow chart of the present invention.
Specific embodiment
In order to further understand the content, features and effects of the present invention, the following examples are hereby given, and with reference to attached drawing
Detailed description are as follows：
Fig. 1, a kind of drilled pile waste mud secondary hardening solid-liquid separation treatment method are referred to, innovative point is, packet
Include following processing step：
S1 precipitates discarded slurry introducing sedimentation basin, and the landwaste for being deposited in lower part directly throws aside spoil disposal area.
Discarded slurry after precipitation removes rock slag is introduced buffer pool by S2, by 1：The ratio of 1 (volume ratio) adds water to stir
Dilution, and add in and take off steady medicament, it carries out breaking steady processing, buffering sedimentation early period.
S3 will break steady integrated apparatus by sludge pump by breaking the discarded slurry surely handled input sludge early period, and sludge is broken
The sludge integrated processing machine of Ou Yi science and technology production can be used in steady integrated apparatus, adds in take off steady medicament again, carries out secondary broken
Steady processing, makes the sedimentations such as heavy metal ion, organic matter and other polluters more thorough, and forces realization solid-liquid by force (forcing) pump
Separation.
The dehydrated sludge that S4 is isolated is discharged through sludge conveyer, and desiccation forms mud cake, and mud cake can be used as side slope protection
Planting soil, Dumping Sites are reclaimed or ground is made in river shoal.The sewage isolated can be recycled, first, being introduced into the buffer pool in S2, use
Discarded slurry is diluted, second is that for dissolving the de- steady medicament to be added in S2 and/or S3；Or the sewage isolated is discharged into dirt
Water treatment facilities, rear direct emission up to standard.
The de- steady medicament used in above-mentioned S2 and S3 is more preferably two kinds, takes off steady medicament and uses cation polypropylene
Amide and aluminium polychloride.
This drilled pile waste mud secondary hardening solid-liquid separation treatment method is compared with existing method for processing waste slurry, tool
Advantageous effect be：
1st, the technique enables discarded slurry all to be handled, and both avoids water and soil pollution, has evaded ring water Bao Chu
Risk is penalized, and has complied with the environmental protection policy of country and local government, harmonious local relationship.
2nd, due to local soil topsoil only 10~30cm thickness, underlie sand pebble layer, and the mud cake that sludge is isolated is just
The construction difficult problem that planting soil extremely lacks in construction can be efficiently solved as the planting soil of side slope protection.
3rd, economic benefit is huge.By taking Huan's line of field as an example, based on every cube of 50 yuan of planting soil, planting soil about 200,000 is completely needed
Side can save 10,000,000 yuan of the expense of purchase planting soil.
4th, mud cake can also be used to reclamation, increases arable land for the local common people, gets public subsidies, deep by local government
It is praised with the common people.
