The popularization of processing equipment and the raising of wastewater treatment rate, the yield of sludge are also sharply increased.Statistical data shows, at present in the world
The sludge of generation up to 100,000,000 tons/year, the annual municipal sewage plant's dewatered sludge yield of China up to more than 30,000,000 tons, and
The processing cost of sludge is up to the 40%-60% of Sewage Plant overall running cost.Meanwhile, because of industrial wastewater in municipal sewage treatment
Import, and the biochemistry Sunk-fund effect of metal ion, result in more heavy metal accumulation among sludge.Data shows,
In China's municipal sludge, up to 7 eight 3.4-3096.3mg/kg (dry weight), Cu is (dry up to 131.2-394.5mg/kg for the content of Zn
Weight), in addition with other heavy metals, such as Cd, Cr, Hg, Ni, Pb etc., the presence of these heavy metals not only has a strong impact on sludge
Subsequent secure is disposed and is utilized, and can also cause the significant wastage of metals resources.By taking Zn as an example, Chinese cities and towns sludge yield in 2010
For 30,000,000 tons (8 0% moisture content), Zn contents based on 1500mg/kg (dry weight), then press just up to 9000 tons by Zn contents therein
Shanghai futures exchange Zn 15000 yuan/ton of meters of quotation in the recent period, the potential age deduction which contains is just up to 1.35 hundred million yuan.
At present, the minimizing technology about Heavy Metals in Sludge mainly has chemical method, bioleaching solvent extraction method and electrochemical process
Deng.Mainly by adding medicament, change sludge Acidity of Aikalinity carries out dissolution to metal to chemical method, then precipitate with heavy metal generation,
The chemical reactions such as complexation realize the separation of heavy metal, and chemical method high cost, technique are loaded down with trivial details, and gained precipitate and separate is difficult, and is easier to
Produce secondary pollution.Bioleaching is the heavy metal in sludge to be transferred in liquid phase using microorganism acid production, then
Solid-liquid separation obtains the sludge for cleaning, and is the preferable processing mode of current effect, but time-consuming very long, generally requires eight -10 days,
And process conditions are required strictly, the presence of heavy metal also can produce toxic action to leaching microorganism.Electrochemical treatment is also referred to as
For electro reclamation, it is mainly used in previously heavy metal pollution of soil reparation, migrates soluble metal ion by applied voltage rich
Collection, is then removed by means such as electro-deposition or ion exchanges.Electrochemical process is in the low water permeability materials such as soil are processed
Have the advantages that in terms of heavy metal that clearance is high, process time is short, while remove various heavy, therefore can gradually receive in recent years
To attention.Or but traditional apparatus for electrochemical treatment is positioned over garbage between negative and positive level, in cathode chamber with anode room
Electrolyte is added, it is impossible to make full use of current efficiency；Garbage is positioned over into anode, but electrode is contacted with sludge and do not filled
Point, cause electrolytic efficiency low, and operating cost is higher.Therefore improvement processing meanss especially research and develop industrial processing meanss is
Electrochemical process remove and middle heavy metal of recycling the waste key.
