Description
Technical field
The invention belongs to field of environment protection equipment, and in particular to a kind of device for dehydrating sladge waste based on microbiological coagulation method and its
Method of work.
Background technology
Sludge dewatering, is, by the primary of fluidised form, concentration or digested sludge removing moisture, to be converted into semisolid or solid-state clod
A kind of method for sludge treatment.By after dehydration, moisture percentage in sewage sludge can be reduced to 80 55 percent to percent, depending on dirt
Depending on the efficiency of the property and dehydration equipment of mud and sediment.The further dehydration of sludge then claims sludge drying, and dewatered sludge contains
Water rate is less than 10.The method of dehydration, mainly there is nature desiccation method, mechanical dehydration method and comminution granulation.Natural desiccation method and
Mechanical dehydration method is applied to sewage sludge.Comminution granulation is applied to the sludge of coagulating sedimentation.
Sludge produced by sewage disposal has water content higher, due to the characteristic that moisture is combined with mud granule, adopts
Mechanically removing has certain limitation, the content of organic matter, the addition of ash content ratio particularly flocculant in sludge
For final solid content important.In general, 20%~30% solid content, institute can be obtained using mechanical dehydration
The sludge of formation is also referred to as mud cake.The moisture content of mud cake is still higher, and with fluid properties, its disposal difficulty and cost are still
It is higher, it is therefore necessary to further decrement.Now, outside natural air drying, evaporation only is formed by being input into heat, can
Realize extensive decrement.The treatment being dried using heat is exactly heat drying.
Typical sludge treatment technique flow, including four treatment or disposal stage.First stage is sludge condensation, mainly
Purpose is to make the preliminary volume reduction of sludge, reduces the volume or place capacity of subsequent treatment structures；Second stage is sludge digestion, is made
Organic matter in sludge is decomposed；Phase III is sludge dewatering, makes the further volume reduction of sludge；Fourth stage is sludge treatment, is adopted
Final sludge is dissolved with certain approach.Still contain substantial amounts of pollutant in the clear liquid of each stage generation or filtrate above
Matter, thus should send back to and be acted upon in sewage disposal system.
Under prior art conditions, the technology of device for dehydrating sladge waste not yet mature, existing traditional handicraft, treatment side
Method still has that processing cost is high, the low shortcoming of dehydration rate.
