Description
Technical field
The present invention relates to the system and method that organic wastewater collaboration Industrial Solid Waste prepares ultrahigh water filler.
Background technology
The backfill technology development in the goafs such as colliery all relatively lags behind all the time, reduces the efficiency of mining, increased
The cost of mining, the potential safety hazard of reduction is caused to society and environment.Ultrahigh water filler is used as a kind of emerging backfill
Material causes increasing concern.Ultrahigh water filler must possess good performance, could be used for goaf filling and put
Exploitation is changed, should specifically possess following key property：The compression strength of the filler after the 1st, solidifying should exceed 2MPa；2、
There must be good fluid ability, long distance delivery requirement could be met；3rd, suitable curing characteristics (is primarily referred to as material
Presetting period and final setting time)；4th, compared with mining costs, with relatively low cost；5th, safety and stability higher.With
On five kinds of key propertys be that tradition prepares the problem that ultrahigh water filler needs to consider, but with resource exploitations such as collieries
Go deep into, this several key property can not meet actual demand.Such as, pollute increasingly severe now, roof drain is to be in
If acid, permeate the ground, then certain corrosion function can be caused to filler；Ultrahigh water filler solidifying body is exposed to sky
Slacking is received in gas, its support strength can be also had a strong impact on；During the underwater constructions such as ocean, it is necessary to filler have it is enough
Anti-permeability performance and erosion-resisting characteristics etc..Additionally, the primary raw material of existing ultrahigh water filler is flyash, cement, raw stone
Ash, gypsum, foaming agent and water etc., various composition are required for cost higher, so, the filling mining of high water filling material is difficult to
Obtain considerable economic benefit.
China's economic development is rapid, and substantial amounts of energy resource consumption generates substantial amounts of industrial solid castoff (abbreviation Industrial Solid
It is useless), Industrial Solid Waste is mainly including red mud, desulfurated plaster, metallurgical slag, CHARACTERISTICS OF TAILINGS SAND and gangue etc..The Eleventh Five-Year Plan period Industrial Solid
Useless 11,800,000,000 tons of total growth, always increases 19,000,000,000 tons of storage newly.15,000,000,000 tons of Industrial Solid Waste total growth during " 12 ", it is total new
Increase 27,000,000,000 tons of storage.With the continuous quickening of China's process of industrialization, these Industrial Solid Wastes account for a large amount of soils to be existed at any time simultaneously
Pollute the danger of environment.
Meanwhile, from urban domestic wastewater to petrochemical industry, metallurgy, papermaking, ferment wine brewing, pharmacy, textile printing and dyeing wastewater all
Belong to organic wastewater, organic wastewater be with organic pollution and by bacterial virus pollute based on waste water, organic wastewater easily causes
Water Eutrophication.Organic wastewater is directly discharged can cause serious pollution to environment, and serious threat is caused to health of human body,
So organic wastewater has to pass through effective treatment and could discharge.With the increase of China human mortality quantity, urbanization process plus
Hurry up, industrial develops rapidly and plant-scale continuous expansion, organic wastewater presentation quantity is more, the trend that concentration is high, toxicity is big.
Burning method is to process organic wastewater with air deep oxidation under high temperature, is most effective most thoroughly means, is also high
Warm deep oxidation method treatment organic wastewater most easily realizes industrialized method.Usual COD>100g/L, calorific value>10500kJ/kg's
High-concentration waste water, processes more reasonable than other methods, more economical with burning method.In general, content of organics is more than 10%
Organic harmful waste liquid mostly makees final process using burning.Using burning method can exhaustive oxidation divides at high temperature by harmful organic substance
Solution, generates carbon dioxide and water, and the clearance of the organic matter in waste liquid is up to more than 99.99%, and process time is short, investment
It is few, take up an area small.
But burning method has the shortcomings that equipment investment is big, processing cost is high, except some special waters (such as hospital wastewater
Need sterilization) must be using outside the method, the treatment of general organic wastewater is difficult to be processed using burning method.
