Abstract
The invention relates to a phosphorus removal compound flocculating agent prepared from red mud and a preparation method and a use method. Aluminum sulfate and the red mud are prepared into a weak acidic or neutral mixed solution. The phosphorus removal compound flocculating agent has the advantages that: the preparation method is simple, the phosphorus removal effect is good, the medicament preparation cost is low, and the combined method resource utilization of the red mud is realized, and the phosphorus removal compound flocculating agent has remarkable economic benefits and social benefits.
Description
Technical field
The present invention relates to a kind of utilize red mud to make dephosphorization composite flocculation agent and preparation method and using method, by integrated process red mud resource utilization, join in trade effluent reaction tank, to remove high concentration phosphorus in waste water and suspended substance.The invention belongs to industrial waste water treatment.
Background technology
Red mud is the waste produced in aluminum oxide production process, often produces 1 ton of aluminum oxide and about produces red mud more than 1.5 tons, because China there is no effective industrialized treatment method before this, becomes a worldwide magazine difficult problem together.A large amount of red muds can not fully effectively utilize, and large-area stockyard can only be relied on to stack, occupy a large amount of soil, also cause serious pollution to environment.The content of each composition of integrated process red mud is: SiO
2about about 20%, CaO40%, Al
2o
3about 10%, Fe
2o
3about 10%, temperature about 90 DEG C during discharge.
Summary of the invention
For solve the problems of the technologies described above the invention provides a kind of utilize red mud to make dephosphorization composite flocculation agent and preparation method and using method, object utilizes the composite flocculation agent that integrated process red mud and Tai-Ace S 150 are Material synthesis, preparation method is simple, and phosphor-removing effect is good, reduces costs.
For reaching the dephosphorization composite flocculation agent that above-mentioned purpose the present invention utilizes red mud to make, the slightly acidic be made up of Tai-Ace S 150 and red mud or neutral mixing solutions.
The preparation method of the dephosphorization composite flocculation agent utilizing red mud to make, it is characterized in that: under the condition stirred, the red mud that integrated process is produced is added in alum liquor, the pH value of Simultaneously test mixing solutions, as mixing solutions pH value 6.0-7.2, stop adding red mud, cross leaching filtrate, namely obtain composite flocculation agent.
According to raw water quality, mixing solutions is dropped in sewage, then through mixing, flocculation reaction, precipitation, high concentration phosphorus and partial suspended thing can be removed.
The composite flocculation agent made adds immediately in mixing pit.
Advantageous effect of the present invention: preparation method is simple, and phosphor-removing effect is good, and medicament preparation cost is low, achieves the recycling of integrated process red mud simultaneously, has significant economic benefit and social benefit.
