Abstract
The present invention relates to a kind of dephosphorization composite flocculation agent utilizing red mud to make and preparation method and using method.The faintly acid being made up of aluminum sulfate and red mud or neutral mixed solution.Advantages of the present invention effect: preparation method is simple, and phosphor-removing effect is good, and medicament preparation cost is low, is simultaneously achieved the recycling of combination method red mud, has significant economic benefit and social benefit.
Description
Technical field
The present invention relates to a kind of dephosphorization composite flocculation agent utilizing red mud to make and preparation method and using method, by combination method red mud resource utilization, join in industrial wastewater reaction tank, to remove the high concentration phosphorus in waste water and float.The invention belongs to industrial waste water treatment.
Background technology
Red mud is produced garbage in aluminum oxide production process, often produces 1 ton of aluminium oxide and about produces red mud more than 1.5 tons, owing to China there is no effective industrialized treatment method before this, becomes a worldwide magazine difficult problem together.Substantial amounts of red mud can not sufficiently effective utilize, and large-area stockyard can only be relied on to stack, and occupies a large amount of soil, environment also causes serious pollution.The content of each composition of combination method red mud is: SiO2About about 20%, CaO40%, Al2O3About 10%, Fe2O3About 10%, temperature about 90 DEG C during discharge.
Summary of the invention
A kind of dephosphorization composite flocculation agent utilizing red mud to make and preparation method and using method is provided for solving the above-mentioned technical problem present invention, purpose utilizes the composite flocculation agent that combination method red mud and aluminum sulfate are Material synthesis, preparation method is simple, and phosphor-removing effect is good, reduces cost.
For reaching the dephosphorization composite flocculation agent that the above-mentioned purpose present invention utilizes red mud to make, the faintly acid being made up of aluminum sulfate and red mud or neutral mixed solution.
Utilize the preparation method of the dephosphorization composite flocculation agent that red mud makes, it is characterized in that: under conditions of stirring, the red mud that combination method produces is added in aluminum sulfate solution, measure the pH value of mixed solution simultaneously, as mixed solution pH value 6.0-7.2, stop adding red mud, cross leaching filtrate, i.e. obtain composite flocculation agent.
According to raw water quality, mixed solution is put in sewage, be then passed through mixing, flocculation reaction, precipitation, the most removable high concentration phosphorus and partial suspended thing.
The composite flocculation agent made adds immediately to mixing pit.
Advantages of the present invention effect: preparation method is simple, and phosphor-removing effect is good, and medicament preparation cost is low, is simultaneously achieved the recycling of combination method red mud, has significant economic benefit and social benefit.
