Abstract
The invention relates to the technical field of pollution wastewater treatment, and particularly relates to a method for preparing an efficient phosphorus removal and ammonia-nitrogen removal agent. The method comprises the following concrete steps: (1) sequentially adding crystal aluminum chloride, magnesium phosphate and poly-dimethyl diallyl ammonium chloride to an agitator according to the weight ratio of 1:(0.75-1.25):(0.001-0.01), and fully agitating; (2) adding proper 0.01-0.1% magnesium oxide to prepare the product. By adopting the removal agent, ammonia-nitrogen and phosphorus in the pollution wastewater can be effectively removed, the removal agent is good in removal effect, non-toxic and environment-friendly, the dosage of phosphorus is reduced, and the cost is reduced. In addition, the preparation method of the removal agent is simple and convenient to operate and easy to put into production.
Description
Technical field
The present invention relates to pollutant effluents processing technology field, be specifically related to the preparation method of efficient dephosphorization and ammonia nitrogen removal agent.
Background technology
Ammonia nitrogen and phosphorus are a kind of nutritive substances, significant to biological growth.Yet, if ammonia nitrogen and phosphorus are present in water body in a large number, can cause body eutrophication, planktonic algae is increased, reduce oxygen in water, simultaneously ammonia nitrogen can produce toxicity to fish, and it will produce great harm or death to fish and other aquatic organisms when in water body, ammonia concentration is greater than 0.2mg/L.Therefore,, for preventing that ammonia nitrogen and phosphorus from polluting and endangering in water body, must before entering water body, this pollutant carry out strict processing to it.In prior art, utilize magnesium ammonium phosphate sediment to generate and can effectively remove ammonia nitrogen and phosphorus, but its complex operation, cost are high, removal effect is bad.
Summary of the invention
The object of this invention is to provide a kind of ammonia nitrogen and the phosphorus that can effectively remove in pollutant effluents, and the preparation method of the efficient dephosphorization that removal effect is good, easy and simple to handle, cost is low and ammonia nitrogen removal agent.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: the preparation method of efficient dephosphorization and ammonia nitrogen removal agent, and concrete steps are as follows:
(1), 1:0.75～1.25:0.001～0.01 adds successively crystal aluminum chloride, trimagnesium phosphate and Poly Dimethyl Diallyl Ammonium Chloride in agitator by weight, fully stirring;
(2), to add weight part be 0.01～0.1% magnesium oxide, makes finished product.
The present invention has following beneficial effect: the preparation method of efficient dephosphorization of the present invention and ammonia nitrogen removal agent, first in agitator, add successively crystal aluminum chloride, trimagnesium phosphate and Poly Dimethyl Diallyl Ammonium Chloride, and fully stir; Add and then appropriate magnesium oxide, make finished product, thereby can effectively remove ammonia nitrogen and phosphorus in pollutant effluents, removal effect is good, and asepsis environment-protecting, has reduced the consumption of phosphorus, reduces costs.In addition, the preparation method of this remover is easy and simple to handle, is easy to go into operation.
Embodiment
Below the present invention will be further described in detail.
Embodiment mono-: the preparation method of efficient dephosphorization and ammonia nitrogen removal agent, and concrete steps are as follows:
(1), 1:0.75:0.001 adds successively crystal aluminum chloride, trimagnesium phosphate and Poly Dimethyl Diallyl Ammonium Chloride in agitator by weight, fully stirring; Wherein, crystal aluminum chloride does not burn, nontoxic, soluble in water; Poly Dimethyl Diallyl Ammonium Chloride is safe, nontoxic, soluble in water, nonflammable, cohesive force is strong, stability to hydrolysis is good, to after above-mentioned crystal aluminum chloride and Poly Dimethyl Diallyl Ammonium Chloride mix and blend, for pollutant effluents, process, can effectively remove ammonia nitrogen and phosphorus, and removal effect is good.
(2), by the remover work in-process that prepare in step (), remover work in-process are 100 parts by weight, the magnesium oxide that adds 0.1 part, make finished product, here magnesian is to be used as neutralizing agent, magnesium oxide alkalescence, absorption property is good, can be used as the neutralizing agent that contains sour waste gas, wastewater treatment, contains heavy metal and organic waste liquid processing etc.
Embodiment bis-: the preparation method of efficient dephosphorization and ammonia nitrogen removal agent, and concrete steps are as follows:
(1), 1:1:0.005 adds successively crystal aluminum chloride, trimagnesium phosphate and Poly Dimethyl Diallyl Ammonium Chloride in agitator by weight, fully stirring;
(2), by the remover work in-process that prepare in step (), remover work in-process are 100 parts by weight, add the magnesium oxide of 0.5 part, make finished product.In the present embodiment, other is all identical with embodiment mono-.
Embodiment tri-: the preparation method of efficient dephosphorization and ammonia nitrogen removal agent, and concrete steps are as follows:
(1), by weight 1:1.25:0.01, in agitator, add successively crystal aluminum chloride, trimagnesium phosphate and Poly Dimethyl Diallyl Ammonium Chloride, fully stirring;
(2), by the remover work in-process that prepare in step (), remover work in-process are 100 parts by weight, add 0.01 part of magnesium oxide, make finished product.In the present embodiment, other is all identical with embodiment mono-.
Finally explanation is, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, other modifications that those of ordinary skills make technical scheme of the present invention or be equal to replacement, only otherwise depart from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of claim scope of the present invention.
