Abstract
The invention provides a preparation method of a gangue filling material. The preparation method comprises the following steps of crushing gangue into particles having the size of 10cm*10cm, putting the particles into a furnace, carrying out calcination at a temperature of 800-1000 DEG C for 30-60min, mixing the calcined gangue, clay and water to obtain a uniform mixture, putting the mixture into a pelletizer, carrying out pelleting, wherein a ratio of the calcined gangue, clay to water is 80-90: 10-5: 10-5, and carrying out 24h anticorrosion protection on the filling material particles by an immersion film-formation method to obtain the finished product. An antiseptic use ratio is 50mg/L, the antiseptic comprises a surfactant and organophosphorus and a ratio of the surfactant to organophosphorus is 3: 1.
Description
Technical field
The present invention relates to the processing filler of sewage, the product obtaining through remodeling has stronger absorption property, good carrier function.
Background technology
Gangue is the solid waste discharging in coal mining process and coal washing process, is a kind of black gray expandable rock lower, harder than coal with a kind of phosphorus content of coal seam association in coalification course.The inorganic constituents of gangue is mainly oxide and some rare metal of silicon, aluminium, calcium, magnesium, iron.China accumulates gangue and reaches more than 1,000,000,000 tons, also will discharge every year 100000000 tons of gangues.
There are more than 1500 of hillocks in the whole nation at present, 3,000,000,000 tons of accumulating amounts above (accounting for the more than 40% of Chinese industrial solid waste total emission volumn), due to a large amount of stackings of gangue, not only cover soil, influence ecological environment, gangue leaching water will pollute surrounding soil and underground water, and in gangue, contain certain combustible, issue and be conigenous combustion in suitable condition, discharge sulfur dioxide, nitrogen oxide, the pernicious gas such as oxycarbide and flue dust pollutant atmosphere, affect the healthy of Residents in Mining Area, as once there is the accident of being poisoned to death because of the Spontaneous Combustion of Coal Gangue personnel that cause in Benxi, Liaoning mining area.
Along with continuing to increase of national environmental protection law enforcement dynamics, the raising of people to environmental quality requirement, solve gangue environmental pollution problem and seem more and more outstanding, after gangue burning, there are the advantages such as specific area is large, absorption property is strong, make full use of the active ingredient of gangue, turn waste into wealth, the effective way of contaminated solution.
The present invention utilizes the resource accessory substance of gangue just, prepares its filler, improves the Disposal quality of sewage, strengthens sewage and recycles, for environmental protection provides new approaches, for enterprise energy-saving and cost-reducing provides new breakthrough.
Summary of the invention
The object of the invention is to: the new product of gangue filler is provided, its stable performance, absorption property is good, applied widely, has reached former designing requirement.
The object of the present invention is achieved like this: a kind of preparation method of gangue filler, implements step by step;
1) gangue is crushed to 10cm × 10cm particle, is placed in stove, at 800-1000 DEG C of roasting 30-60min;
2) gangue of roasting is mixed and is placed in granulator granulation with clay, water, wherein gangue: clay: the ratio of water is 80-90:10-5:10-5;
3) adopt and soak the method for diaphragm suspension, to step 2) one-tenth particulate filler carry out 24h anti-corrosion protection, obtain product; Wherein addition is 50mg/L, and anticorrisive agent is surfactant, organophosphor, and its mixing ratio is 3:1.
Action principle of the present invention: utilize Xinjiang resource accessory substance gangue as base-material, from the design of fragmentation, roasting, balling-up, the product obtaining through screening and preparation, its adsorption effect be improved significantly, there is good microbe carrier effect, make demonstration for energy-saving and cost-reducing, shown technological progress.
Detailed description of the invention
The present invention is described further in conjunction with the embodiments.
Embodiment
1) gangue is crushed to 10cm × 10cm particle, is placed in stove, at 950 DEG C of roasting 45min;
2) gangue after roasting is mixed and is placed in granulator granulation with clay, water, wherein gangue: clay: the ratio of water is 80:10:10; Or 90:5:5;
3) above-mentioned filler is carried out to anticorrisive agent protection 24h, after completing, be filler.
Wherein: anti-corrosion protection is the life cycle in order to extend filler, reduce the infringement of sewage to filler itself and a kind of safeguard measure of doing; Anticorrisive agent adopts the method for soaking diaphragm suspension, and the gangue after granulation is put into holder, and interpolation anticorrisive agent is 50mg/L, and wherein anticorrisive agent is surfactant and organophosphor, and its mixing ratio is 3:1; Interpolation surfactant, the organophosphor selected are sells product.
The production checking of product of the present invention:
That upper conventional ceramic packing, flyash filler carry out contrast test for the index such as COD, ammonia nitrogen in sewage to gangue filler and market.
Take from Urumqi City's Sewage Plant sewage, (COD:489.47mg/L in former water, ammonia nitrogen: 40.04mg/L), under identical condition, detected respectively COD, the ammonia nitrogen of the water by processing at the 4th day, the 7th day, and the result is in table 1,2.
Table 1 water outlet COD clearance
Table 2 water outlet ammonia nitrogen removal frank
Learnt by above table: gangue filler has good absorption property in as sewage disposal, for microorganism provides good carrier.
Gangue and preparation that the present invention selects are commercially available prod.
