Abstract
The invention provides a technical scheme of a filter material for dephosphorizing wastewater and a manufacturing method thereof. The filter material in the scheme is spherical particles with the diameter of 3 to 5mm. The particles consist of the following components which are produced in the metallurgical industry in percentage by weight: 78 to 82 percent of solid waste granulating slag and the balance of cement. The manufacturing method in the scheme has the following steps of: 1, grinding the metallurgical industrial solid waste granulating slag with moisture content of lower than 15 percent, sieving with a 200-mesh sieve to obtain 78 to 82 weight parts of granulating slag powder, and stirring and mixing the granulating slag powder and 18 to 22 weight parts of cement with a label of more than No.400; 2, feeding mixed powder obtained in the first step into a pelletizer for pelletizing, wherein water in the amount which is 25 to 30 percent of the using amount of the cement is required to be added in the pelletizing process and the diameter of each pellet is in the range of 3 to 5mm; 3, placing finished pellets obtained in the second step into a curing box for curing until the cylindrical compressive strength is more than 5MPa; and 4, sieving the cured particle pellets to obtain finished products.
Description
Technical field
What the present invention relates to is a kind of sewage disposal material, especially a kind of filtrate and manufacture method that is used for waste water dephosphorization.
Background technology
In the prior art; be used for the biological aerated filter process that water purifies; usually the filtrate that adopts is a haydite; and the raw material of producing haydite mainly contains shale, clay etc.; therefore; the production of ceramic grain filter needs a large amount of land resource, because the policy in state guarantee soil causes haydite output to be restricted.And in the face of serious environmental pollution day by day, BAF is increasing to the demand of high-quality filtrate.The production of adding ceramic filtrate also needs high-temperature firing again, so production cost is also high, and this is the existing in prior technology weak point.
Summary of the invention
Purpose of the present invention is exactly at the existing in prior technology deficiency, and a kind of filtrate and manufacture method technical scheme that is used for waste water dephosphorization is provided, and this scheme is to adopt the spherical particle of being made by the solid waste grain slag and the cement of metallurgical industry generation.Utilize grain slag as the feedstock production filtrate, preparation technology is simple, can realize the resource of trade waste, reduces production costs protection land resource.And itself contains several mineral materials grain slag, can stripping supply with growth of microorganism, can also be coupled with outer added elements, forms novel dephosphorization process.
This programme is realized by following technical measures:
This programme is used for the filtrate of waste water dephosphorization, is characterized in that described filtrate is the spherical particle of diameter at 3-5mm, and this particle is made up of solid waste grain slag and cement that metallurgical industry produces, and wherein the weight of grain slag accounts for 78-82%, and all the other are cement.
This programme is used for the manufacture method of waste water dephosphorization filtrate, and the processing step of its manufacturing is as follows:
The first step is got water content and is lower than 15% metallurgical industry solid waste grain slag and crosses 200 mesh sieves after crushed and get grain slag powder 78-82 weight portion, with label be that cement 18-22 weight portion more than No. 400 mixes;
In second step, the mixed powder that the first step is mixed is sent into pelletizer and is made ball, needs to add the water of cement consumption 25-30% in making the ball process, and the diameter of making ball is at 3-5mm;
The 3rd step, will put into and carry out maintenance in the curing box through second balling-up that produce of step, up to cylindrical compress strength greater than 5MPa;
The 4th step, the particle ball after maintenance is sieved, get finished product.
The concrete characteristics of the described manufacture method of this programme also have the 3rd the step in balling-up process of maintenance in curing box be, left standstill earlier 4 hours, then 10 degree/hour within programming rate heated up 3 hours, enter constant temperature, the temperature of constant temperature is at the 43-45 degree, and the time of constant temperature is 24 hours, begins cooling then, cooling rate be controlled at 10 the degree/hour within, lower the temperature reached till the room temperature in 6 hours.
The beneficial effect of this programme can be learnt according to the narration to such scheme, because this scheme is to adopt the spherical particle of being made by the solid waste grain slag and the cement of metallurgical industry generation.Al in the grain slag
2O
3Higher with CaO content, phosphate is had very high adsorption effect.The filtrate that utilizes grain slag to make for raw material can keep higher removal effect to ammonia nitrogen, and slowly release the growth of microorganism trace elements necessary for nitration reaction improves basicity in running.Can also be coupled with outer added elements, form novel dephosphorization process, and can reclaim phosphor resource.Utilize grain slag as the feedstock production filtrate, preparation technology is simple, can realize the resource of trade waste, reduces production costs protection land resource.This shows that the present invention compared with prior art has outstanding substantive distinguishing features and obvious improvement, the beneficial effect of its enforcement also is conspicuous.
The specific embodiment:
For clearly demonstrating the technical characterstic of this programme,, this programme is set forth below by a specific embodiment.
The filtrate that this programme is used for waste water dephosphorization is the spherical particle of diameter at 3-5mm, this particle is made up of solid waste grain slag and cement that metallurgical industry produces, wherein the weight of grain slag accounts for 78-82%, all the other are cement, this specific embodiment adopts the weight of grain slag to account for 80%, and all the other 20% are cement.
It is as follows that this programme is used for the processing step of manufacture method of waste water dephosphorization filtrate:
The first step is got water content and is lower than 15% metallurgical industry solid waste grain slag and crosses 200 mesh sieves after crushed and get grain slag powder 80kg, with label be that No. 425 cement 20kg mixes;
In second step, the mixed powder that the first step is mixed is sent into pelletizer and is made ball, adds the water of 5-6kg in making the ball process as required, and the diameter of making ball is at 3-5mm;
The 3rd step, will put into and carry out maintenance in the curing box through second balling-up that produce of step, up to cylindrical compress strength greater than 5MPa; The process of maintenance is, left standstill earlier 4 hours, then 10 degree/hour within programming rate heated up 3 hours, enter constant temperature, the temperature of constant temperature is at the 43-45 degree, and the time of constant temperature is 24 hours, begin then the cooling, cooling rate be controlled at 10 the degree/hour within, lower the temperature reached till the room temperature in 6 hours.
The 4th step, the particle ball after maintenance is sieved, get finished product.
The present invention is not limited in the above-mentioned specific embodiment, and the variation that those of ordinary skills make in essential scope of the present invention, remodeling, interpolation or replacement also should belong to protection scope of the present invention.
