Put and be connected with effluent holding reservoir.
Further, described primary sedimentation defecator is connected with effluent holding reservoir, and described secondary precipitation defecator is with dirty
Water reservoir is connected, and by that analogy, n times precipitation defecator is connected with effluent holding reservoir.
Further, described inorganic salt extraction element includes: liquid mixes pond and depositing reservoir, and described liquid mixes pond and is arranged at each nothing
The front end of machine salt extraction element, described depositing reservoir is arranged at the rear end of each inorganic salt extraction element.
Further, it is the storage mud groove of one or more pyramidal structure bottom described depositing reservoir, the bottom of described storage mud groove
It is provided with sludge pump.
Further, described inorganic salt extraction element also includes: sedimentation device, and described sedimentation device is arranged in depositing reservoir
For solid-liquid separation.
Present invention also offers the processing method of above-mentioned Novel reclamation sludge treating system, comprise the following steps:
A. the mud of municipal wastewater or trade effluent or water supply plant is collected together, be stored in warehouse of sludge (1)；
B. the mud in warehouse of sludge is transported in adjusting means, mixes homogenizing process through one section, by sludge conditioning
To moisture content more than 85%；
C. the sludge solutions of moisture content more than 85% is pumped into inorganic salt dissolver, and pump in inorganic salt dissolver
Enter inorganic salt lytic agent, through stirring by the inorganic salt dissolution in mud to liquid phase, remove extracellular polymeric simultaneously, obtain

～90min；
E. the inanimate matter solution extracted through inorganic salt extraction element (5) enters inanimate matter solution reservoir (11), and the mud of precipitation enters
Enter desanding device (6)；
F. entrance primary sedimentation device of the inorganic salt solution in inanimate matter solution reservoir (11) (121) carries out precipitation, precipitation
Thing recycles through primary sedimentation defecator (131)；Supernatant in primary sedimentation device (121) enters secondary precipitation dress
Putting (122) and carry out precipitation, precipitate recycles through secondary precipitation defecator (132)；By that analogy, by previous step
Supernatant in Zhou enters n times settler (12n) and carries out precipitation, and precipitate precipitates defecator (13n) through n times and returns
Receive and utilize, in the sewage that inorganic matter disposal unit produces and rear entrance effluent holding reservoir (14), (N >=2)；
G. in step e, the mud of entrance desanding device (6) is through desanding, and organic sludge is partially into Organic Sludge solution reservoir
(7), bulky grain solid silt particle can do construction material；
H. the organic sludge after desanding can be directly used for anaerobic methane production gas, or recycles as carbon source, or is returned by organic sludge
For Sewage Plant；Can also pass through dehydration device (8) to be for further processing, the organic sludge after dehydration can carry out compost, or
As earthworm feedstuff after process；Can also pass through desiccation apparatus (9) to be for further processing, the mud after mummification can be made through pelletize
For bio-fuel；Can also pass through incinerator (10) to be for further processing, the product after burning can do construction material, burns and produces
Heat amount can be used for the thermal source of desiccation apparatus (9)；
I. the sewage produced in whole system enters effluent holding reservoir (14), through the process of sewage disposal system (15), reaches row
Put standard；
J. after sewage disposal is up to standard, a part is back to the regulation homogenizing of pretreatment, and a part is back to inorganic salt and extracts, another
Partial discharge.
The processing method of a kind of Novel reclamation sludge treating system the most according to claim 9, it is characterised in that institute
The content of microorganisms stated in step h in the organic sludge after desanding rises to more than the 40% of raw sewage.
