Description
Technical field
The present invention relates to a kind of sludge base charcoal, more particularly to a kind of sludge base charcoal preparation side of the paper powder that adulterates
Method.
Background technology
Charcoal refers to the biomass remaining material after high temperature pyrolysis under anoxic conditions.Charcoal has larger ratio
Surface area and loose structure, with good absorption property, can adsorb heavy metal, the ammonia in water as sewage disposal adsorbent
Nitrogen, phosphate etc..
With Development of China's Urbanization, town sewage plant construction is advanced by leaps and bounds, and municipal sludge is total as sewage disposal accessory substance
Amount also drastically rises, if the mishandling secondary pollution that can cause environment.The treatment disposal of sludge has turned into current environment face
The Tough questions for facing.
In municipal sludge contain a certain amount of carbon, can as the raw material for preparing charcoal, but its also because contained by sludge into
Divide complexity, institute's phosphorus content is relatively low, therefore the simple charcoal quality being made of it and performance are compared with commercial biological charcoal gap very
Greatly, its range of application is also limited significantly with value.
Paper powder refers to the thin fibre that finished paper, paper product processing waste material, waste paper, paper pulp or the ground reprocessing of pulpboard are formed
Dimension or powder.Paper powder is mixed in sludge, the phosphorus content of sludge can be improved, the sludge base charcoal quality of preparation can be made more preferably,
Absorption property is more preferably.
The present invention takes and prepares charcoal to the paper powder that adulterated in sludge, improves the absorption property of sludge base charcoal, while
Realize the recycling of sludge and waste paper.
The content of the invention
Preparation method and application it is an object of the invention to provide a kind of sludge base charcoal of the paper powder that adulterates, with one kind
Simple exercisable mode, improves the performance of sludge base charcoal, lifts its absorption dirt-removing power in sewage disposal application.
The purpose of the present invention is achieved by the following scheme:
1st, raw material prepares
Municipal sludge (moisture content 72-80%) is air-dried under field conditions (factors), is then placed in baking oven and is dried to constant weight in 105 DEG C,
4-8mm, then ground, 200 mesh sieves excessively are crushed to after removing the debris such as stone.Finished paper, paper product processing waste material, reclaimed waste paper shine
Crushed through special equipment after dry, ground, sieved, the powder official form for filing a lawsuit powder as 200 mesh.
2nd, preparation process
(1) 1~5 is pressed:The sludge that will have been blended and paper powder of 1~3 weight ratio are sufficiently mixed, standby.
(2) the material by step (1) is inserted in atmosphere Muffle furnace, is passed through the nitrogen 15min of 100-200mL/min, after with 10-
The programming rate of 20 DEG C/min is heated to 400-600 DEG C, and after stopping 2-3h, stopping is heated and is cooled to 80 DEG C of dischargings, is placed on dry
Cooling obtains thermal decomposition product in dry device.
(3) the hydrochloric acid for (2) step being obtained thermal decomposition product 1M embathes 5min.
(4) step hydrochloric acid (3) is filtered off, is filtered after solid content is soaked into 20min with deionized water, deionized water is soaked and mistake
Filter step is repeated 5 times, then the upper thing of filter is put into baking oven in 105 DEG C of drying to constant weight, the final sludge base life for obtaining doping paper powder
Thing charcoal.
The advantage of the invention is that:
The preparation cost of sludge base charcoal has been saved, the limitation of sludge base charcoal preparation has been overcome so that sludge
Turn waste into wealth with waste paper, while largely improving the quality and sewage disposal performance of sludge base charcoal.
