Description
Technical field
The invention belongs to wastewater treatment and agricultural fertilizers to apply field, and in particular to a kind of accurate biogas slurry application device machine and
Its application method.
Background technique
In recent years, China's intensive aquaculture industry is grown rapidly, and is producing the same of huge Social benefit and economic benefit
When, a large amount of Animal fecal pollution waste is also produced, Livestock pollution improvement has become social concern concerned by people.To improve ring
Border quality, promote livestock and poultry breeding industry health, sustainable development, livestock breeding wastewater is effectively treated have become one kind must
So.Due to pig farm breeding wastewater there are high-content organic matter, high-content ammonia nitrogen, concentration of suspension is big a series of problems, such as, at present
Existing treatment process is difficult to obtain satisfactory result to the processing of pig farm breeding wastewater.
Domestic many scholars have carried out many researchs to the comprehensive utilization of biogas slurry, focus primarily upon biogas slurry and exist as organic fertilizer
The application influence to agricultural product quality, the influence to soil physico-chemical property, the safety evaluation to environment, biogas slurry in Agro-ecology
Diseases prevention bacteriostasis and application as word material or word feed additives in aquaculture.Due to nutrition rich in biogas slurry
Substance and mineral element, germ quantity significantly reduces after anaerobic fermentation, and can play the role of improveing soil, so mesh
The mode of pre-treatment biogas slurry is mainly based on pouring fertilising.
Anaerobic ferment process can effectively remove the organic matter in the breeding wastewater of pig farm, but through anaerobic fermentation treated biogas slurry
In still contain a large amount of nitrogen phosphorus and remaining organic matter.During livestock manure fermented, in addition to carbon element loss is larger, other
90% nutriment is retained in biogas slurry and biogas residue.Especially N, P and K content is very big, and is converted into simple, easy
The shape of ammonia nitrogen is converted into the small molecule or ionic condition of passive plant absorption, such as organic nitrogen a part in organic waste
Formula is equivalent to available nitrogen；Another part then participates in being metabolized or being decomposed into amido nitrogen such as free amino acid form.Due to fermentation raw material
Difference, the content of the nutrient in biogas slurry is also different.From the point of view of nutritional ingredient, some data show total in the fertilizer of natural pond
Nitrogen (TN) content accounts for 0.78~1.61%, and total phosphorus (TP) content accounts for 0.4~0.6%, and total potassium (TK) content accounts for 0.61-1.30%,
Ratio shared by organic matter is maximum in nutritional ingredient, and the content of usual organic matter accounts for as 36.0-49.9%.Biogas slurry is because containing nitrogen phosphorus
Equal plant growths element, it is possible to substitute traditional fertilizer as crop fertilizer and multipurpose additive.But biogas slurry makes as fertilizer
With dosage must be limited to reasonable range, if amount of application is relatively low, nutrient needed for plant growth can not be provided, influences to make
The yield of object；And biogas slurry amount of application is excessively high that the series of problems such as the excessive, Heavy Metal Accumulation of ammonia volatilization amount will be present.Tradition biogas slurry at present
Method of application such as pressure control can not accomplish precisely to apply so that the amount of application of biogas slurry is difficult to control effectively.
CN104355518 A discloses a kind of feces of livestock and poultry anaerobic ferment devices with biogas slurry reflux pipeline, including detests
Aerobe fermentation tank also passes through a digestive juice pipeline and is connected to solid-liquid separating machine, and solid-liquid separating machine is connected to a biogas residue pipeline, Gu
Liquid separator also passes through a biogas slurry first pipe and is connected to biogas slurry holding vessel, and biogas slurry holding vessel and a biogas slurry second pipe connect
Logical, biogas slurry second pipe is connected to a biogas slurry third pipeline, biogas slurry second pipe also pass through a biogas slurry reflux line and into
Expect device connection.Use cannot be directly brought for solving the biogas slurry after anaerobic fermentation, needs to blend into not according to different needs
The confinement problems being used with the dilution of concentration or after carrying out disinfection.
CN106664927 A discloses a kind of intelligent biogas slurry application device and method.It mainly include liquid storage unit, sprinkling list
Member and automatic control unit；The liquid storage unit, including sink, biogas slurry slot, nitrogen, phosphorus, potassium and microelement nutritious liquid slot；It is described
Spray unit, including infusion pump, perfusion tube, marsh liquid filter and separation of heavy metal ions device；The automatic control unit, including
DDC controller, Autosampler, elemental analysis unit, motorized adjustment valve group and sensor.The device uses intelligent control mode
The form for adding artificial parameter to optimize makes while meeting Different Crop and crop Various Seasonal, growth period biogas slurry application demand
User can select most economical, reasonable parameter according to crop actual conditions, meet the biogas slurry application of practical various complex conditions
Demand realizes that intelligent control is applied with the intelligent biogas slurry efficient, safe, flexible, that nutritional ingredient is controllable combined from main regulation
Mode.
