Point.The present invention is the method that the later stage is dried by drying box by enzyme-added processing early stage, significantly the time of reduction measure calcification.
Granule sludge calcification in a small amount of processing anaerobic reactor, is had using main processing, application technology:Chemical method, row
Sludge.Granule sludge calcification is suppressed by chemical method, mainly by adding chemical reagent and appropriate increase basicity without notable
Increase pH value in raw water, the sediment of generation can suitably be lowered into the calcium in anaerobic reactor, it is also ensured that granule sludge knot
The stability of structure；Calcification sludge is decomposed by way of arranging sludge, does not obtain good effect.
The content of the invention
It is an object of the invention to provide a kind of method for determining granule sludge calcification in paper waste.Carried using the present invention
The method of confession can be easy to remove the organic matter in sludge by simple and quick addition enzyme preparation, control temperature, retain calcareous.Together
When accelerate lysozyme, the organic matter that protease penetrates into granule sludge gap and granule sludge surface reacts, and accelerates organic matter to depart from.
The technical scheme that the present invention solves above-mentioned technical problem is as follows：
The method of granule sludge calcification, this method comprise the following steps that in a kind of measure paper waste：
(1) sample：Take the granule sludge of 200g weight in wet bases.
(2) pre-process：Granule sludge is subjected to impregnating pretreatment；By water of the granule sludge at 35~40 DEG C, 60g albumen
Impregnated in enzyme or 60g lysozymes, dip time 6h.Mud granule is fully absorbed, and by the organic of mud granule surface
Thing is reacted away as far as possible, convenient to determine calcium content.
(3) heating water bath：Pretreated granule sludge is put into saline bottle and sealed, with 37 DEG C in thermostat water bath
Temperature water bath heat 6h, and initial gross separation is carried out during heating water bath.
(4) it is ultrasonically treated：Saline bottle is placed in ultrasonic wave, design temperature is 37 DEG C, and the time, its effect was logical for 20min
High vibration, crushed particles sludge structure, the area that increase enzyme preparation contacts with granule sludge are crossed, and enough frictions are provided
Power, facilitate the separation of organic matter.
(5) separate：Feed liquid is obtained after being ultrasonically treated be put into filter screen to sieve, while use distilled water flushing.Obtain
Filter residue be placed in drying box dry, survey solids content.The solids content measured is the content of calcification in granule sludge.
The beneficial effects of the invention are as follows：The fast separating process pre-processed using enzyme preparation, accelerate granule sludge organic matter
Stripping, so as to shorten measure granule sludge calcification time.
