Description

A kind of sludge conditioning broken wall reaction unit
Technical field
The utility model relates to a kind of sludge conditioning broken wall reaction unit, belongs to field of environment protection equipment.
Background technology
Along with the quantity discharged of urban industry waste water and sanitary sewage is increasing, treatment rate of domestic sewage also improves year by year, the sludge yield of municipal sewage plant also sharply increases, a large amount of excess sludges will discharge in sewage work, the mud of enormous amount needs to do further process, if mud can not get reasonable process, secondary pollution will be caused.Mud carries out pre-treatment, nurses one's health, and comprises concentrated, dehydration, dry.Mud after mummification, can apply to land reclamation, building materials utilization etc., and landfill requires that moisture percentage in sewage sludge is less than 60%, and how to reduce the water ratio of mud, this is the vital task of sludge treatment.Existing dewatered sludge technique adopts thermal source or electric energy heating, and energy consumption is larger.
Utility model content
The purpose of this utility model is to provide a kind of sludge conditioning broken wall reaction unit, and native system is integrated with broken wall, flocculation, solidification, sterilization are nursed one's health in one, automatically speculates the medicament needed, without the need to manual operation, improves the dewatering of mud.
The purpose of this utility model is achieved through the following technical solutions: form primarily of solidifying agent quantitative feeder, Shaftless screw conveyor, stirrer, sludge reaction tank, broken wall agent chemicals dosing plant, PAM chemicals dosing plant and iron(ic) chloride chemicals dosing plant, it is characterized in that: the inside center of described sludge reaction tank is provided with stirrer, and arranges frame blade on the rotation axis of stirrer; The bottom of described sludge reaction tank is provided with the cone end, and the bottom at the cone end is provided with shore pipe; Described solidifying agent quantitative feeder connects the solidifying agent dog-house of sludge reaction upper end by Shaftless screw conveyor.
Described broken wall agent chemicals dosing plant is connected with the broken wall agent dosing mouth of sludge reaction upper end by pipeline.
Described PAM chemicals dosing plant is connected with the PAM dosing mouth of sludge reaction upper end by pipeline.
Described iron(ic) chloride chemicals dosing plant is connected with the iron(ic) chloride dosing mouth of sludge reaction upper end by pipeline.
Principle of work of the present utility model: during the utility model operation work: in mud gravity concentration tank, mud is by after natural subsidence gravity concentration, removes the free water in mud, through under meter metering by entering mud pipe by mud suction sludge reaction tank.The first step, broken wall agent is added to sludge reaction tank by broken wall agent chemicals dosing plant, start stirrer, sewage treatment plants generally adopts Biochemical method, containing remaining microorganism in a large number in mud, residue microorganism water ratio is higher, needs the microorganism structure destroying this part mud, so that dewater further; Second step, adds PAM by PAM chemicals dosing plant to sludge reaction tank, strengthens the dewatering of mud after adding PAM medicament; 3rd step, adds iron chloride salt by iron(ic) chloride chemicals dosing plant to sludge reaction tank, and iron chloride salt contributes to the dewatering efficiency improving follow-up dehydration equipment; 4th step, adds solidifying agent by solidifying agent quantitative feeder and Shaftless screw conveyor to sludge reaction tank, and solidifying agent is generally unslaked lime, molysite etc. and has stronger water-absorbent, and unslaked lime can also play disinfection.
In sum, the beneficial effects of the utility model are: native system is integrated with broken wall, flocculation, solidification, sterilization are nursed one's health in one, automatically the medicament needed is speculated, without the need to manual operation, improve the dewatering of mud, follow-up dehydration equipment is easy to drop to less than 60% by moisture for mud, and system has automatic operating, automatic discharging, energy-conservation feature; Containing remaining microorganism in a large number in mud, residue microorganism water ratio is higher, needs the microorganism structure destroying this part mud, so that dewater further; Add PAM and solidifying agent respectively by PAM chemicals dosing plant and solidifying agent quantitative feeder, solidifying agent is generally unslaked lime etc. and has stronger water-absorbent, and unslaked lime can also play disinfection.
