Description

Organic wastewater cooperates with the system and method for Industrial Solid Waste preparation ultrahigh water filler
Technical field
The present invention relates to the system and methods of organic wastewater collaboration Industrial Solid Waste preparation ultrahigh water filler.
Background technique
The backfill technology development in the goafs such as coal mine all relatively lags behind all the time, reduces the efficiency of mining, increases The cost of mining causes the security risk of reduction to society and environment.Ultrahigh water filler is as a kind of emerging backfill Material causes more and more to pay close attention to.Ultrahigh water filler must have good performance, could be used for goaf filling and set Change exploitation, should specifically have following basic performance: 1, the compression strength of the filler after solidifying should be more than 2MPa;2, There must be good fluid ability, just be able to satisfy long distance delivery requirement;3, suitable curing characteristics (is primarily referred to as material Presetting period and final setting time);4, compared with mining costs, there is lower cost;5, higher safety and stability.With On five kinds of basic performances be tradition preparation ultrahigh water filler problem in need of consideration, but with resource exploitations such as coal mines Go deep into, these types of basic performance is no longer satisfied actual demand.Such as, pollute now increasingly severe, roof drain is to be in If acid, permeate the ground, then can cause certain corrosion function to filler;Ultrahigh water filler solidifying body is exposed to sky By slacking in gas, its support strength can be also seriously affected;When the underwater constructions such as ocean, filler is needed to have enough Anti-permeability performance and erosion-resisting characteristics etc..In addition, the primary raw material of existing ultrahigh water filler is flyash, cement, raw stone Ash, gypsum, foaming agent and water etc., various composition require higher cost, so, the filling mining of high water filling material is difficult to Obtain considerable economic benefit.
China's economic development is rapid, and a large amount of energy consumption produces a large amount of industrial solid castoff (abbreviation Industrial Solid It is useless), Industrial Solid Waste mainly includes red mud, desulfurized gypsum, 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 " 12th Five-Year Plan " are 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 and exist simultaneously at any time 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 pollutant and by bacterial virus pollute based on waste water, organic wastewater easily causes Water Eutrophication.Organic wastewater direct emission can cause serious pollution to environment, pose a serious threat to health of human body, So organic wastewater has to pass through effective processing and could discharge.With the increase of China human mortality quantity, urbanization process adds Fastly, the trend that quantity is more, concentration is high, toxicity is big is presented in industrial rapid development and plant-scale continuous expansion, organic wastewater.
Incineration method is to handle organic wastewater with air deep oxidation under high temperature, is most effective most thorough means, and high Warm deep oxidation method processing organic wastewater most easily realizes industrialized method.Usual COD > 100g/L, calorific value > 10500kJ/kg High-concentration waste water is handled more reasonable than other methods, more economical with incineration method.In general, content of organics is greater than 10% Organic harmful waste liquid mostly makees final process using burning.Using incineration method can exhaustive oxidation divides at high temperature by harmful organic substance Solution, generates carbon dioxide and water, and the removal rate of the organic matter in waste liquid is up to 99.99% or more, and short processing time, investment It is few, it takes up little area.
But incineration method has the shortcomings that equipment investment is big, processing cost is high, in addition to certain special water (such as hospital wastewaters Need sterilization) must be using outside the method, the processing of general organic wastewater is difficult to be handled using incineration method.
Summary of the invention
It is an object of the invention to handle the preparation ultrahigh water filling of the solid wastes cooperative disposal organic wastewater such as red mud, desulfurized gypsum Material provides the system and method for organic wastewater collaboration Industrial Solid Waste preparation ultrahigh water filler, it both handled red mud, taken off The solid wastes cooperative disposal organic wastewater such as sulphur gypsum is able to produce ultrahigh water filler again simultaneously.The system and method are not only realized Comprehensive utilization and the zero emission of Industrial Solid Waste recycling, Industrial Solid Waste and organic wastewater materialization, also reduce ultrahigh water and fill The production cost of filling chock material.
