Description
Technical field
The present invention relates to a kind of process field of sludge water from water works, the specially concentration of spoil disposal water and coagulant is synchronously molten
The application process of the device gone out and the device.
Background technology
The spoil disposal water water that waterworks water-purifying process is produced accounts for the 1.5%~4% of the total water purification amount of water factory, and moisture content exists
99.7% or so；Its main component includes inorganic mineral (such as clay), coagulant hydrolysate (such as Al (OH)3、Fe(OH)3), with
And a small amount of impurity such as organic matter and microorganism.Spoil disposal water is directly discharged to water body without processing, not only wastes the water money of preciousness
Source, while also can polluted-water.For waterworks of the use aluminium salt as flocculant, contain a large amount of aluminium salts in its spoil disposal water,
Certain toxic action can also be caused to storing the aquatile in water body.Treatment for Reuse, one are carried out to sludge water from water works
Aspect can save great lot of water resources, and the pollution to storing water body is greatly reduced；On the one hand the part in spoil disposal water can also be reclaimed
Coagulant, so as to effectively reduce the coagulant consumption of waterworks.
Currently, recycling processing technique scheme both at home and abroad on running water spoil disposal water, can be divided into 2 major classes.One class is base
In spoil disposal water high concentration suspended matter characteristic, the Treatment for Reuse using separation of solid and liquid as main purpose of progress；One class is to be directed to spoil disposal
The coagulant hydrolysate remained in water, the Treatment for Reuse that main purpose is recovered as with coagulant of development.Wherein, the former core
The heart is the raising of spoil disposal water thickening efficiency, is available for the technical method used and equipment to include traditional gravity concentration tank, granulation
Fluid bed concentration technique, integration of sludge concentrating and dewatering equipment etc.；The key of the latter is then that Al, Fe's in spoil disposal water solid phase is molten
Go out or extract, conventional method includes acidifying, alkalization, ion exchange etc..

Area is big, and Construction and operation cost is high.Although thickening efficiency can be improved by coagulation pretreatment, the consumption of coagulant is added
Amount.Chinese invention patent (CN201210343711.X) discloses a kind of efficient concentration device of spoil disposal water, the device by
PAM is added in spoil disposal water and sets the technical scheme of knockout tower to realize the raising of spoil disposal water thickening efficiency, but can not the row of realization
The recovery of coagulant in muddy water.
The technical problem underlying that coagulant is recycled in spoil disposal water is there is still a need for setting up the processing of follow-up spoil disposal water
Disposal process.After being recycled through coagulant, the clear liquid rich in Al, Fe can mix progress reuse with raw water of waterworks, remain
Remaining most of mud mixture, it is still desirable to further carry out separation of solid and liquid, could realize spoil disposal water deals carefully with disposal.
In addition, when reclaiming coagulant using acid-base method, because a large amount of added acid or alkali, also needing to adjust pH before reuse is carried out.
In a word, so far, there is not yet on the synchronous separation of solid and liquid of sludge water from water works and coagulant recovery method
Open with device is reported.
