Top cover 11 returns to initial position, opens top cover 11, the clear water of twice sludge volume is added, makes the cell of the microorganism in sludge
Osmotic pressure abrupt change, extracellular clear water quickly enter intracellular, rupture cell expansion, it may be difficult to which the combination water of removal becomes freely
Water.Supersonic generator 12 can also be opened simultaneously, under ultrasonic wave effect, addi-tional crusher cell.
4, permeable lid 44 is adjusted by controller 4 and covers leakage fluid dram 42, open simultaneously the external thrust of driving of top cover 11
Sludge is pressed onto minimum volume by axis, be expressed to recirculated water receiving chamber receive water it is unchanged in 1h until.In order to increase water removal
Weight can will be arranged inside top cover 11 in rate.The water of discharge may return to step 3 and is recycled.Containing in sludge at this time
Water rate is 20% or so, if not high to water content requirement, can only proceed to this step, opens 10 bottom of clasmatosis room and opens
It closes, or opens top cover 11, recycle sludge.
If 5, there are requirements at the higher level to moisture content, top cover 11 is returned into original position, removes recirculated water receiving chamber, is tightly connected
Cryodesiccation chamber 30 is then turned on freezing unit 14, temperature is adjusted, by the sludge adfreezing in clasmatosis room 10.
Later on 10 bottom switch of clasmatosis room, falls into sludge in cryodesiccation chamber 30, closes 10 bottom of clasmatosis room
Portion's switch adjusts watertightness lid 43 and covers leakage fluid dram 42, restores the sealing state of clasmatosis room 10 and cryodesiccation chamber 30.
Or top cover 11 is opened, the sludge of adfreezing is taken out, is put into sludge individually by the feeding port 36 in cryodesiccation chamber 30
In the cryodesiccation chamber 30 of setting, feeding port 36 is closed, guarantees the sealing state of cryodesiccation chamber 30.
Vacuum pump 35 is opened, after required vacuum state is reached in cryodesiccation chamber 30, opens heating plate 31, in the sludge that distils
Moisture；Asepwirator pump 34 is opened simultaneously, the vapor generated in cryodesiccation chamber 30 is all collected into vapor collecting chamber 32.User
Heating time can be adjusted according to demand, to control the practical moisture content of sludge.
