Abstract
The invention discloses an efficient deep cone sludge thickener. The efficient deep cone sludge thickener comprises a deep-cone settling tank barrel, an upper oblique cone, a lower oblique cone, a deep-cone settling tank cone body, a deep-cone settling tank discharge barrel, a deep-cone settling tank discharge port, a deep-cone settling tank overflow port, a deep-cone settling tank feeding port, a deep-cone settling tank flocculating-agent feeding port, a static mixer, a stirring device, a deep-cone settling tank feeding barrel, a feeding barrel baffle, and the like. The efficient deep cone sludge thickener effectively overcomes the disadvantages that an activated sludge gravity thickener or a gravity thickening tank of a municipal sewage treatment plant is large in occupied land area and low in treating efficiency. The efficient deep cone sludge thickener provided by the invention effectively shortens the settling time, increases the production efficiency, reduces the water content of thickened sludge, saves the cost of sludge dehydration treatment and creates conditions for subsequent deep dehydration of the thickened sludge.
Description
[technical field]
The present invention relates to a kind of sludge from wastewater treatment plant concentration device, be particularly useful for the concentration of sludge sewage.
[background technology]
In municipal sewage treatment process, the moisture percentage in sewage sludge that water supply purification water treatment produces is generally 99.3%～99.7%, and activated sludge is generally 99.2%～99.6%, and mixing sludge is generally 97%～98%.The feature of municipal sludge is that the few moisture of solid objects is large,, needs through concentration before sludge dewatering for this reason, to reduce the moisture content of mud, makes sludge volume reduce the processed of being convenient to mud.
The concentrated mode of traditional mud can be divided into three kinds of modes such as the concentrated and centrifugal concentrating of gravity concentration, air supporting.Gravity concentration is to utilize sedimentation principle thickened sludge, is divided into clearance-type and continous way; Air supporting is concentrated is that tiny steam bubble makes the density of mud granule be less than water and float, and is concentrated; Centrifugal concentrating is the density difference of utilizing solid phase in mud, liquid phase, is subject to different centrifugal force and both are separated in High Rotation Speed, reaches concentrated object.Air supporting is concentrated all exists power consumption operating cost higher with centrifugal concentrating technique, complex management, and processing cost is high and seldom applicable.
The efficient dark cone sludge concentration device of one of the present invention, effectively overcome municipal sewage plant's activated sludge gravity concentration floor space large, the shortcoming that treatment effeciency is low, effectively shorten the sedimentation time, improve productivity ratio, reduce the moisture content of thickened sludge, saved sludge dewatering treatment cost, for the follow-up deep dehydration of mud has been created condition.
[summary of the invention]
The object of the present invention is to provide a kind of efficient dark cone sludge concentration device, overcome gravity concentration floor space large, treatment effeciency is low, the shortcoming that thickened sludge moisture content is high.Provide a kind of and effectively shorten the sludge settling time, boost productivity, reduce the enrichment facility of thickened sludge moisture content.This device is made up of parts such as deep-cone settling groove drum body, upper oblique cone, lower oblique cone, deep-cone settling groove cone, deep-cone settling groove discharge barrel, deep-cone settling groove discharging opening, deep-cone settling groove overfall, deep-cone settling groove charging aperture, deep-cone settling groove flocculant charging aperture, static mixer, agitating device, deep-cone settling groove feeding cylinder, feeding cylinder baffle plates.Said deep-cone settling groove drum body, its effect is to provide the space of a sedimentation separation; Said upper oblique cone, its effect one is the micro-solid particle that separating liquid is carried secretly, the 2nd, current stabilization; Said lower oblique cone, its effect one is the distance that shortens sedimentation, the 2nd, the area of increase sedimentation; Said deep-cone settling groove cone, its effect is that the mud sliding after sedimentation separation is concentrated arrives discharge barrel; Said deep-cone settling groove discharge barrel, its effect is the mud of collecting after sedimentation separation concentrates; Said deep-cone settling groove discharging opening, its effect is that the mud after sedimentation separation is concentrated is discharged; Said deep-cone settling groove overfall, its effect is that the clear liquid after sedimentation separation is discharged; Said deep-cone settling groove charging aperture, its effect is that the mud that needs sedimentation separation is sent into; Said is deep-cone settling groove flocculant charging aperture, and its effect is that the flocculant of needs is sent into; Said static mixer, its effect is that flocculant is evenly mixed in mud; Said agitating device, its effect is further flocculant and mud to be mixed; Said deep-cone settling groove feeding cylinder, its effect is that the flocculation mud mixing is delivered to settled layer; Said feeding cylinder baffle plate, its effect is the effect that strengthening is uniformly mixed.
Use one of the present invention deeply to bore sludge concentration device, effectively shortened the sedimentation time, improved productivity ratio, reduced the moisture content of mud, saved sludge dewatering treatment cost, for the follow-up deep dehydration of mud has been created condition.

Fig. 1 is a kind of efficient dark cone sludge concentration device.1 is deep-cone settling groove drum body; 2 is upper oblique cone; 3 is lower oblique cone; 4 is deep-cone settling groove cone; 5 is deep-cone settling groove discharge barrel; 6 is deep-cone settling groove discharging opening; 7 is deep-cone settling groove overfall; 8 is deep-cone settling groove charging aperture; 9 is deep-cone settling groove flocculant charging aperture; 10 is static mixer; 11 is agitating device; 12 is deep-cone settling groove feeding cylinder; 13 is feeding cylinder baffle plate.
[specific embodiment]
As shown in Figure 1, with slush pump by the activated sludge of municipal sewage plant's moisture content 99.5% be delivered to flocculant that deep-cone settling groove charging aperture 8 carries with deep-cone settling groove flocculant charging aperture 9 mix laggard enter static mixer 10 mix, mud after mixing enters subsider feeding cylinder 12, under the synergy of agitating device 11 and feeding cylinder baffle plate 13, mud and flocculant generation flocculation reaction, reacted mud enters sedimentation separation, supernatant liquor is under upper oblique cone 2 effects, after the micro-solid particle that further separating liquid is carried secretly, discharge by deep-cone settling groove overfall, under the effect of sedimentation separation layer mud layer by lower oblique cone 3, enter deep-cone settling groove cone 4, in groove cone 4, mud flco is progressively compressed to deep-cone settling groove discharge barrel 5, realize the concentration process of mud, mud after concentrated is discharged from deep-cone settling groove discharging opening 6, it is 93.5% that thickened sludge moisture content reaches, and has realized the degree of depth concentration process of municipal sewage plant's activated sludge.
