Liquid, lime white are stirred, and the sedimentation basin is used to carry out separation of solid and liquid to the waste liquid in agitator tank after chemical reaction, thereon
Portion's clear liquid overflow enters in clean water tank, and base sludge is drained into incineration plant dump pit by slush pump, the clear liquid in the clean water tank
Lime pulping system is entered by draining pump to reuse.
Further, the sedimentation basin is that tube settler, inclined-plate clarifying basin, machine add one kind in pond.
Further, the bottom of pond of the sedimentation basin is domatic to the inclined sludge gravity flow of connection mixing tank side；The sludge
The domatic gradient of flowing automatically is not less than 2 °.
Further, it is additionally provided with purpose ceramic-film filter between the sedimentation basin and clean water tank.
The beneficial effects of the invention are as follows：The present invention realizes the regeneration of diafiltration concentrated liquor, i.e., from percolate depth
Concentrate caused by reason, agitator tank is entered by elevator pump, adds lime slurry in agitator tank, it is agitated it is well mixed after,
Precipitated into sedimentation basin, upper clear supernate utilizes into lime pulping system, and base sludge enters dump pit.This technical scheme
Both solved dope emission problem, and realized water resources comprehensive utilization again.
Other advantages, target and the feature of the present invention will be illustrated in the following description to a certain extent, and
And to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, Huo Zheke
To be instructed from the practice of the present invention.The target and other advantages of the present invention can by following specification realizing and
Obtain.
