Abstract
The utility model discloses a high-efficiency deep cone sludge thickening device which mainly 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 hole, a deep cone settling tank overflow hole, a deep cone settling tank feeding hole, a deep cone settling tank flocculating agent feeding hole, a static mixer, a stirring device, a deep cone settling tank feeding barrel, and a feeding barrel baffle. The high-efficiency deep cone sludge thickening device effectively overcomes the defects that an activated sludge gravity thickening tank or a gravity thickening pool of a municipal sewage treatment plant is large in occupied land area and low in treating efficiency, thus effectively shortening the settling time and creating conditions for the subsequent deep dehydration of thickened sludge.
Description
[technical field]
The utility model relates to a kind of sludge from wastewater treatment plant concentration device, is particularly useful for the concentration of sludge sewage.
[background technology]
In the municipal sewage treatment process, the moisture percentage in sewage sludge that the 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 characteristics of municipal sludge are that the few moisture of solid objects is large,, need before sludge dewatering through concentration for this reason, to reduce the moisture content of mud, make sludge volume reduce the processed of being convenient to mud.
The concentrated mode of traditional mud can be divided into gravity concentration, air supporting is concentrated and three kinds of modes such as centrifugal concentrating.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 float less than water, and is concentrated; Centrifugal concentrating is to utilize the density of solid phase in mud, liquid phase different, is subject to different centrifugal force and both are separated in High Rotation Speed, reaches concentrated purpose.Concentrated and the centrifugal concentrating technique of air supporting all exists the power consumption operating cost higher, complex management, and processing cost is high and seldom use.
A kind of efficient dark cone sludge concentration device described in the utility model, effectively overcome municipal sewage plant's activated sludge gravity concentration floor space large, the shortcoming that treatment effeciency is low, also shortened the sedimentation time, improved productivity ratio, reduced the moisture content of thickened sludge, saved the sludge dewatering treatment cost, for the follow-up deep dehydration of mud has been created condition.
[summary of the invention]
The purpose of this utility model is to provide a kind of effective shortening sludge settling time, boosts productivity, and reduces the enrichment facility of thickened sludge moisture content, overcomes the gravity concentration floor space large, and treatment effeciency is low, the shortcoming that the thickened sludge moisture content is high.A kind of efficient dark cone sludge concentration device described in the utility model includes 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 plate formation.Said deep-cone settling groove drum body is the support component of this device, is the back taper three-dimensional-structure, the cone cone angle be 60 the degree angle; Be provided with static mixer on deep-cone settling groove drum body top, be provided with deep-cone settling groove flocculant charging aperture and deep-cone settling groove charging aperture on static mixer, the collaborative agitating device effect of feeding cylinder baffle plate is set in deep-cone settling groove drum body, be provided with oblique cone and lower oblique cone at deep-cone settling groove facies superior pyramidis, deep-cone settling groove feeding cylinder and deep-cone settling groove discharging opening are set below deep-cone settling groove cone, are provided with deep-cone settling groove overfall at deep-cone settling groove drum body upper right side.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 are the micro-solid particles that separating liquid is carried secretly, the 2nd, and current stabilization; Said lower oblique cone, its effect one are the distances that shortens sedimentation, the 2nd, and the area of increase sedimentation; Said deep-cone settling groove cone, its effect are that the mud sliding after sedimentation separation is concentrated arrives discharge barrel; Said deep-cone settling groove discharge barrel, its effect are the mud of collecting after sedimentation separation concentrates; Said deep-cone settling groove discharging opening, its effect are that the mud after sedimentation separation is concentrated is discharged; Said deep-cone settling groove overfall, its effect are that the clear liquid after sedimentation separation is discharged; Said deep-cone settling groove charging aperture, its effect are to need the mud of sedimentation separation to send into; Said deep-cone settling groove flocculant charging aperture, its effect is that the flocculant of needs is sent into; Said static mixer, its effect are evenly to be mixed into flocculant in mud; Said agitating device, its effect are further flocculant and mud to be mixed; Said deep-cone settling groove feeding cylinder, its effect are that the flocculation mud that mixes is delivered to settled layer; Said feeding cylinder baffle plate, its effect are to strengthen the effect that mixes.
Use a kind of dark cone sludge concentration device described in the utility model, effectively shortened the sedimentation time, improved productivity ratio, reduced the moisture content of mud, saved the sludge dewatering treatment cost, for the follow-up deep dehydration of mud has been created condition.
