Description
Technical field
The invention belongs to water treatment field, particularly be used for flocculation agent of municipal sewage treatment and Industrial Wastewater Treatment and preparation method thereof.
Background technology
China's water pollution and water source crisis are serious day by day.Water supply gets and sewage purification have become one of main difficult problem that China faces.The enhancing of Along with people's environmental consciousness and China's implementation of sustainable development; Prevent to pollute and protect the work of environment to cause the great attention of governments at all levels; Treatment of Industrial Water and environmental protection requirement improve constantly, and the water conditioner kind is enriched constantly, and performance improves constantly.The flocculation of flocculation agent accounts for critical role in wastewater treatment.
At present, along with the fast development of industry, the task of wastewater treatment is complicated day by day, and the deficiency of single flocculation agent highlights day by day, so efficient composite flocculation agent will become flocculation agent research from now on and the focus of using.Traditional flocculation agent is some inorganic single flocculation agents, and they are Tai-Ace S 150, alum, exsiccated ammonium alum, iron(ic)chloride, ferric sulfate or ferrous sulfate hydrate.These flocculation agents are well used in process such as purify waste water very early.That traditional flocculation agent exists is powerless to sour water, add and excessively make water become muddy, produce shortcomings such as the wadding piece is little.
Summary of the invention
In order to solve the problems of the technologies described above, the present invention provides a kind of flocculation agent, and objectionable impuritiess such as metals ion can be effectively removed in efficiently turbidity removal again; Simultaneously should nontoxic, harmless, the non-secondary pollution of prescription, flocculation is fast, cheap, easy to use; The present invention also provides a kind of production technique of above-mentioned flocculation agent, and this technology has simple possible, characteristics easy and simple to handle.
Flocculation agent provided by the invention, its composition that contains and following at the shared weight percent of flocculation agent:
Calcium hydroxide 75%-90%;
Ferric sulfate 0.8-15%;
Tai-Ace S 150 5%-14%.
Preferably, hydrolysis prepares in the carbide slag that produces behind the acetylene said calcium hydroxide from calcium carbide.
Preferably, its composition that contains and shared weight percent are following:
Calcium hydroxide 90%;
Ferric sulfate 1%;
Tai-Ace S 150 3%;
The present invention also provides the method for the above-mentioned flocculation agent of preparation, and step is following:
1) pulverize carbide slag, the hydrolysis of power taking stone prepares the carbide slag that produces behind the acetylene and in kibbler, pulverizes;
2) mix according to each component percentage composition, takes by weighing carbide slag, ferric sulfate and Tai-Ace S 150 mixing stirring.
Compare prior art, and flocculation agent of the present invention is a kind of composite inorganic flocculation agent, its existing effect that is better than single inorganic flocculating agent has the effect of neutralizing acid wastewater again.The present invention has realized the comprehensive utilization of refuse; And product has raw material and is easy to get; Use simple, cost is low, temperature influence is little, flocs unit is strong to the avidity of mikrobe, can effectively remove suspended substance in the water, colloid, aerobic bacteria etc., and to effects such as environment are nontoxic.The present invention specifically has following advantage:
1. flocculation agent provided by the invention is when handling sewage and trade effluent, and it is big to form flco, and flocculation efficiency is high; Settling velocity is fast; Filterableness is good, and the neutralizing acid wastewater can effectively be removed mud, total plate count and a large amount of metals ion (experimental data is seen table 1).Therefore, the present invention can be widely used in sewage and trade effluent.
2. because the part material of flocculation agent of the present invention is a carbide slag,, flocculation agent of the present invention is easy to get advantage with low cost so having raw material; With carbide slag produce flocculant in next life, can reduce production costs, can turn waste into wealth again, improve environment, for Comprehensive Utilization for Carbide Slag has been opened up a new way.
3. production technique of the present invention, production unit are simple, working condition is to carry out under the normal temperature and pressure, belong to energy-saving and emission-reducing technique.In the whole process of production, no waste gas, waste liquid, waste residue produce, and belong to green recycling economy industry.
