Description
Technical field
The present invention relates to the technical field of sludge dehydration device, relate in particular to automatic compound conditioning system of sludge dewatering and Opsonizing method thereof.
Background technology
Quickening of urbanization process causes the sharp increase of sludge quantity, and mud granule is tiny, and wetting ability is extremely strong, water ratio is up to 95%～99%, therefore, handle mud, just must dewater to mud earlier.Moisture in the mud generally is divided into four kinds of existence forms: interstitial water 70%, capillary water 20%, planar water and mud granule internal water 10%, general mechanical dehydration are difficult to the internal water of the capillary water in the mud, planar water and mud granule is removed.
At present, before carrying out sludge dewatering, must carry out physics, chemical conditioning to mud earlier,, be convenient to subsequent disposal to improve the dewatering of mud.In the conventional art, adopt single polymeric flocculant that mud is nursed one's health, the moisture content of the cake after the conditioning has brought difficulty for follow-up disposal such as mud sanitary landfill, burning up to about 80%.
The Sludge Chemical Conditioning agent is according to the difference of their mechanism of action; Generally comprise following type: one, polymeric flocculant, SEPIGEL 305 (PAM) is the most commonly used, and its mechanism of action is the effect through adsorption bridging; The mud small-particle is connected into macrobead, improve the settling property of mud; Two, inorganic salt high-valence cationic coagulating agent, the high-valence cationic that this coagulating agent hydrolysis forms plays the effect of surperficial water layer (electrostatic double layer) thickness of direct compression mud granule with the negative charge on the mud granule attracts each other and electrically neutralization; Three, coagulant aids, itself does not generally play coagulation, and the pH value that is to regulate mud is supplied with mud with the holey skeleton, improves the mud granule structure, destroys mud colloidal stability, improves the coagulation effect of coagulating agent, strengthens flco intensity; Four, tensio-active agent; Its solublization and dissemination have changed the size and the hydrophilic and hydrophobic of mud flco; Make the part combination water change into free water, the association of its hydrophobic structure destroys the colloidal open structure of mud flco, makes the Sludge Surface hydrophobization; Capillary combination water and surface adsorption water all are able to remove, thereby improve dewatering performance of sludge; Five, oxygenant through the effect of oxygenant and mud flco, destroys the hydrophilic-structure of extracellular polymeric (EPS) in the mud, makes the part combination water change into free water, thereby improves the dewatering of mud.
In actually operating; Use single Sludge Chemical Conditioning agent often to be difficult to reach the purpose of deeply dehydrating sludge; In order further to reduce the water ratio of the mud after the processed, generally adopt compound amendment or with the composite use of amendment, to improve the dewatering of mud.And in compound conditioning system, operating parameterss such as the dosage of each amendment, order of adding, churning time, stirring velocity and reaction times are vital to the final effect of conditioning.Compound conditioning technology to comprise extracellular polymeric in the mud (EPS) dissolving step is an example; Potential of hydrogen must accurately be controlled on the time at stirring reaction; If it is too fast that the alkali solid powder adds; Sludge system will carry out the transition to alkalescence from acidity in advance, and the extracellular polymeric dissolving is not thorough, and the improvement degree of dewatering performance of sludge is not ideal enough; If it is slow that the alkali solid powder added, or mix inhomogeneous, the extracellular polymeric dissolved simultaneously, mikrobe is dissolved the mutual down dispersion of effect in acid, the mud flco is tiny, settling property is poor, is unfavorable for moisture removal.
In the prior art, in the sludge dewatering conditioning device, the amendment that is used for sludge dewatering still needs the manual operation dosing, can't realize robotization control, its inefficiency, and the wasting manpower and material resources, cost is high, its holistic management and inconvenient operation.
Summary of the invention
