Description
Technical field
The present invention relates to environmental pollution water-treatment technology field, particularly a kind of Composite denitrification agent for the treatment of breeding wastewater and using method thereof.
Background technology
Along with the development of China's livestock industry, inter-industry competition is growing more intense, and mass-producing, the intensivization development of livestock industry have become a kind of inexorable trend, and unified management is conducive to reducing costs and increasing economic efficiency; Pig industry is as the major portion of livestock and poultry breeding industry, its rinse pig house cleaning water, rush the breeding wastewater that liquid dung and fecaluria form, because its quantity discharged is large, pollution load is high, produce stench containing a large amount of organism, nitrogen, phosphorus, suspended substance and pathogenic bacterium, become the Focal point and difficult point in current livestock and poultry breeding industry prevention and cure of pollution; And its fund input in sewage disposal is limited because pig farm economic benefit is not high, need to seek a kind of less investment, the treatment process that treatment effect is good.
The breeding wastewater being rich in ammonia nitrogen in high density generally adopts the method such as biological process, chemical precipitation (MAP) method to process; Biochemical process because treatment capacity is large, low cost and other advantages and being used widely, breeding wastewater is after biochemical treatment, although COD, ammonia nitrogen, total phosphorus can reach emission standard substantially, and total nitrogen easily exceeds standard.
Total nitrogen comprises organonitrogen and inorganic nitrogen, and inorganic nitrogen is made up of ammonia nitrogen, nitric nitrogen and nitrite nitrogen; After biochemical treatment, waste water total nitrogen is not up to standard, mainly because organonitrogen cannot effectively be degraded in biological process.MAP method is by adding phosphoric acid salt and magnesium salts in waste water, and the ammonia nitrogen in solution is combined and generates magnesium ammonium phosphate sediment, thus realizes the object removing ammonia nitrogen.But because precipitation dosing is large, and ammonia nitrogen cannot once be removed up to standard, thus limits promoting the use of of MAP method.Adopt single coagulating agent often to can not get desirable treatment effect, therefore, the composite operation technique of medicament becomes the study hotspot of current water treatment field.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, a kind of Composite denitrification agent for the treatment of breeding wastewater and using method thereof are provided, the raw material sources of this Composite denitrification agent are extensive, preparation method is simple, have simultaneously easy to use, once remove advantage up to standard.
Technical scheme provided by the invention is:
For the treatment of a Composite denitrification agent for breeding wastewater, composed of the following components by weight percentage: 10% ~ 25% oxygenant, 20% ~ 40% magnesium salts, 7% ~ 20% phosphoric acid salt, 1% ~ 5% coagulant aids or molysite, all the other are water.
Preferably, described oxygenant is one or more in Potcrate, sodium chlorate, clorox, potassium hypochlorite or hydrogen peroxide.
Preferably, described magnesium salts is one or more mixing in magnesium chloride, magnesium sulfate or magnesiumcarbonate.
Preferably, described phosphoric acid salt is one or more in potassium primary phosphate, dipotassium hydrogen phosphate, SODIUM PHOSPHATE, MONOBASIC or Sodium phosphate dibasic.
Preferably, described coagulant aids is polymerize aluminum chloride, bodied ferric sulfate or aluminium iron polychloride; Described molysite is iron(ic) chloride or ferric sulfate; Above-mentioned coagulant aids and molysite can be used alone, also can be used in combination according to a certain percentage.
The using method of above-mentioned a kind of Composite denitrification agent for the treatment of breeding wastewater is as follows:
Put in pending breeding wastewater by composite good Composite denitrification agent, dosage is the volume ratio of 0.1% ~ 2%, and the reaction times is 20 ~ 150 minutes; Reaction terminates to make the nitrogen content in waste water up to standard, reaches the effect that disposable removal is up to standard.
The dosage of above-mentioned Composite denitrification agent is determined according to the nitrogen content of pending breeding wastewater; If the nitrogen content in waste water is high, and follow-up treatment process has requirement, only need carry out pre-treatment to waste water reduces certain nitrogen content, then also can reduce dosage in proportion to reach pretreating effect.
One provided by the present invention, for the treatment of the agent of breeding wastewater Composite denitrification and using method thereof, compared with prior art, has the following advantages:
Composite denitrification agent of the present invention contains oxygenant and coagulant aids, when this Composite denitrification agent is put in breeding wastewater by a certain percentage, the oxygenant comprised can carry out oxide treatment to the nitrogenous substances in waste water, C-N key in effective destruction organonitrogen, makes it be converted into ammonium nitrogen or nitric nitrogen; Simultaneously coagulant aids can carry out coagulating treatment to nitrogenous substances, and with phosphate radical in solution, magnesium ion generates double salt and sedimentation is removed.
Composite denitrification agent of the present invention both can as the pre-treatment of high-concentration ammonia nitrogenous wastewater, also can as the advanced treatment of Low Concentration Ammonia Containing Wastewater.Realize medicament once to add, reduce labor management and running cost.
Composite denitrification agent raw materials wide material sources of the present invention, preparation method is simple, can on-the-spotly directly prepare, and also can produce by large-scale industrial.
