Abstract
The invention discloses a compound phosphorus removing agent for removing low-concentration phosphorus wastewater. The phosphorus removing agent is composed of manganese ore, hematite, magnetite, plaster stone, carbon residue and an adhesion agent. The material comprises the following components in total weight of the compound phosphorus removing material by mass ratio: 5-8% of manganese ore, 4-8% of hematite, 5-10% of magnetite, 60-75% of plaster stone, 6-10% of carbon residue, and 4-10% of adhesion agent, and the adhesion agent is one or two out of cement, sodium borate and plaster. The compound phosphorus removing agent not only can protect the environment, achieves resource of waste, and also can obtain good social benefit and economic benefit.
Description
Technical field
The present invention relates to a kind of removal low-concentration phosphorus-containing wastewater composite dephosphorizing agent, belong to technical field of chemistry.
Background technology
Phosphorus is the one of the chief elements that maintains life in the earth system, also is to consist of organism and participate in the requisite element of metabolic processes.What element rich lacked, the quality of the environment of phosphorus will directly affect all living things that comprises the people grows.In recent years, body eutrophication has become the problem of worldwide attention, and in general, the total phosphorus in water mass concentration surpasses 20mg/L, can think that water body is in eutrophication.And the principal element that causes body eutrophication is phosphorus and nitrogen, and phosphorus has special effect to the eutrophication of water body.The sewage that contains a large amount of nutritive ingredients flows into the closed water areas such as lake, has accelerated the eutrophication in waters, and this phenomenon comprises that all over the world China all constantly occurs, and has all brought great harm for industry, water industry and agricultural and tourism.After phosphorus-containing wastewater was through series of physical, chemistry, biological treatment, phosphate ion concentration also had about 2mg/L--20mg/L in the water outlet, can not reach discharging standards, and difficult removal.
The processing low-concentration phosphorus-containing wastewater method of commonly using both at home and abroad at present mainly contains the precipitator method, Coagulation Method, biological process and absorption and ion exchange method.(1) precipitator method are as traditional phosphorus removing method, and comparative maturity aspect theoretical Technology produces the problems such as some mud and dephosphorization be thorough not but also exist in the dephosphorization process; (2) biological process has successfully solved the unmanageable shortcoming of precipitator method mud and non-secondary pollution phenomenon, but the treatment process more complicated, biological activity is subject to environmental influence;
(3) ion exchange method is the method for removing the Phosphorus From Wastewater acid ion by phosphate anion being had the adsorbing material of very strong selection.The method investment is little, and technique is simple, but when processing low-concentration phosphorus-containing wastewater, regeneration is frequent, makes troubles to operation.
Summary of the invention
The technical problem to be solved in the present invention is for overcoming the deficiencies in the prior art; a kind of removal low-concentration phosphorus-containing wastewater composite dephosphorizing agent is provided; the present invention not only can protection of the environment, realize the resource utilization of waste, can also obtain good Social benefit and economic benefit.
The technical solution used in the present invention is: dephosphorization agent of the present invention is combined by manganese ore, rhombohedral iron ore, magnetite, plaster stone, breeze and adhesion agent.
The quality that described material accounts for the total mass of composite dephosphorization material than component is: manganese ore 5%-8%, rhombohedral iron ore 4%-8%, magnetite 5%-10%, plaster stone 60%-75%, carbon slag 6%-10%, adhesion agent 4%-10%.
Described adhesion agent is one or both of cement, Sodium Tetraborate, plaster.
Preparation method of the present invention is:
(1) get manganese ore, rhombohedral iron ore, magnetite, plaster stone, breeze and carry out condensation process with cold method under 6 ℃ environment, cover in the 24h behind the little ball forming, 6-8h works the maintenance of sprinkling water after the moulding;
(2) coverture can be used burlap bag, straw shop etc., waters to keep spheroid moistening;
(3) put into the high temperature furnace chamber behind the forming materials, when slowly being warming up to 100～120 ℃, be incubated 60～70 minutes, allow moisture evaporation in the material;
When (4) being warming up to 800 ℃, be incubated 10 minutes, mineral are sloughed crystal water, continue to be warming up to 1165-1185 ℃ again, are incubated 33-45 minute, stopped heating.
The present invention not only can protection of the environment, realize the resource utilization of waste, can also obtain good Social benefit and economic benefit.
