Description
Technical field
The invention belongs to sludge dewatering technical field, and in particular to a kind of transfer electron formula electro-osmosis advanced oxidation sludge takes off
Water system and its dewatering.
Background technology
Sludge is that produce after Sewage Plant active sludge treatment waste water a kind of is highly soluble in the solid matter of water, wherein containing
Substantial amounts of organic matter, poisonous and harmful substance and some inorganic matter fragments.
Sludge has the features such as yield is big, moisture content is high, intractability is big, does not dispose or ineptly treatment sludge has
Secondary pollution may be caused and the health of soil, water source, resident and livestock is endangered.It has been investigated that, the safe disposal of sludge is very
It is effectively to remove the moisture in sludge to the secondary premise for utilizing, so as to reduce the difficulty of disposal link.
The processing mode that sewage treatment plant is commonly used is to utilize plate and frame filter press, centrifugal dehydrator or belt filter press,
Shallow-layer treatment is carried out to sludge by the physics mode such as extruding or centrifugation.Sludge after above-mentioned PROCESS FOR TREATMENT cannot meet me substantially
The increasingly strict specific resistance to filtration standard of state.
In view of the foregoing, deep dehydration technology is increasingly becoming the new way of sludge dewatering.Advanced oxidation system Yin Qigao
The characteristics of water separation capability and shirtsleeve operation mode of effect once turn into research, but due to many actual limitations cannot extensive use,
Such as advanced oxidation system is only for the liquid sludge of moisture content 95%-99%, the dirt after largely adding handled by inorganic medicament
Mud cannot be utilized directly, and the filtrate of removing could be flowed back after must also carrying out complicated treatment.

Moved back and forth along the longitudinal direction in electro-osmosis reactor, reach the effect of more uniform injection, injected in a medicine feeding hole
After complete medicament, reselection another medicine feeding hole repetition above injection process；After injection medicament, injection tube is extracted and by plug weight
Newly get back at medicine feeding hole.
