Description
Technical field
The invention belongs to sludge dewatering technical fields, and in particular to a kind of sludge conditioner and its application.
Background technique
With the continuous quickening of Chinese Urbanization level, municipal sewage treatment amount is continuously improved, and sludge yield is therewith not yet
It is disconnected to increase.Since the moisture content of sludge is high (reaching as high as 99.5%), complicated component not only contains a large amount of organic matters, but also contains
Harmful heavy metal, pathogenic microorganism etc., and dehydration property is poor cause sludge to stack bulky, to subsequent specific resistance to filtration and
Transport brings inconvenience and processing cost is greatly improved.Therefore, the deep dehydration of sludge has become for specific resistance to filtration
Important link.
Currently, sludge conditioner is mainly used for during the sludge conditioning before sludge dewatering, acted on by compression double electric layer,
Absorption electricity in cooperation use, adsorption bridging effect and net catch and roll up sweep act on change mud granule property, to cause sludge
In moisture be easily separated out, be conducive to sludge dewatering subsequent depths reason.However the type of sludge conditioner is more, often
Sludge conditioner mainly has three classes, i.e., inorganic sludge conditioner, organic polymer sludge conditioner and biological sludge conditioning
Agent.The applicating history of inorganic sludge conditioner is the most remote and application range is relatively broad, preparation work extensive with raw material sources
The advantages that skill is simple and price is relatively cheap, but the dosage of inorganic sludge conditioner is usually more, and sludge dewatering effect
Also limited, while the use of a large amount of inorganic sludge conditioners also can cause environmental pollution and influence.Compared to inorganic sludge tune
Agent is managed, organic polymer sludge conditioner is few with added amount of chemical, sludge formation alumen ustum is big, sludge settling property is excellent and contains
The low advantage of water rate, but there is also production costs higher, price costly the disadvantages of.Biological sludge conditioner has safe nothing
Poison, the advantages that being easily degraded by microorganisms, is without secondary pollution, but that there are dosages is larger, make and use higher cost, vulnerable to
The disadvantages of noxious material interferes, largely limits its application in practical projects.
