Abstract
The invention provides a method and device for producing an organic concentrated compound liquid fertilizer from marsh liquid at normal temperature, and aims to provide a method and device for producing an organic concentrated compound liquid fertilizer from marsh liquid, which have the advantages of low cost and high degree of automation. The method comprises steps as follows: marsh liquid is filtered by a marsh liquid filter pond to remove plant fibers, sand grains and other large-granule substances, enters a marsh liquid stock solution storage tank, is pumped to a marsh liquid mechanical filter, a marsh liquid multimedia filter and a marsh liquid precision filter to remove algae, pesticide residues, bacteria and other high-molecular substances, and is filtered by a marsh liquid cross-flow ultrafilter; the unfiltered liquid enters a concentrated liquid storage tank, and the filtrate enters an aromatic polyamide membrane element concentration device to be concentrated and separated; the separated concentrated liquid enters the concentrated liquid storage tank, and is delivered to a marsh liquid preparation tank to prepare the liquid fertilizer; the filtrate enters a pure water storage tank for cleaning equipment; and the liquid fertilizer is sterilized by an on-line sterilizer, and then packaged to serve as a plant liquid fertilizer for crops, flowers and the like.
Description
Technical field
The invention belongs to changing waste into resources and produce the liquid state organic fertilizer preparation field with natural pond liquid, specifically, it relates to a kind of method with physics is produced organic concentrated composite liquid fertilizer under the normal temperature state method and apparatus.
Background technology
Natural pond liquid is the residue that organic waste such as human and animal excreta and agricultural crop straw produce through anaerobically fermenting in methane-generating pit, it is a kind of high-quality fertilizer material, the conventional nutritive ingredient that plants such as farm crop and flowers need in the liquid of natural pond has multiple elements such as nitrogen, phosphorus, potassium, magnesium, calcium trace element on a small quantity, active organic composition has plant hormones such as humic acids, indolylacetic acid, milk-acid bacteria, Plant hormones regulators,gibberellins, phytokinin, and vitamin B group has B
1, B
2, B
5, B
6, B
11, B
12Also contain organic molecules such as multiple amino acids, protein, lytic enzyme and multiple mineral acid and some antibiotic, mutual coordinative role is present in the liquid of natural pond with the form of available nutrient and biological pesticide between these compositions, can directly be absorbed and kill harmful germ and worm's ovum rapidly and promote the growths of plants such as farm crop and flowers, so natural pond liquid also can be described as a kind of medicine fertilizer.The science of natural pond liquid is used the content that can improve soil with organic matter and nutritive element, improves Soil structure, increases soil fertility.
These effective component contents are lower in the liquid of natural pond, concentration is generally about 10%, all the other all are the water and the vegetable fibre of unbound state, silt, bacterium, clay, colloid, pesticide residue, suspended substance and contain the organism of fishy odor, therefore plants such as farm crop and flowers are directly used this natural pond liquid, do not meet agricultural health standard, can cause the secondary pollution in farmland, also can cause disadvantageous effect to growth conditions and growing environment, moreover the amount of directly using this natural pond liquid also is bigger, this certainly will increase the transportation cost and the labour intensity of natural pond liquid, still more non-with fertile season, natural pond liquid can not be fully used, the unnecessary unordered discharging of natural pond liquid has caused the pollution and the waste of environment, for fear of pathophoresis and soil pollution, as fertilizer sources can use after need doing further processing treatment, and an effective way is exactly that composition useful in the liquid of natural pond is extracted, remove redundant moisture and objectionable impurities, carry out purification processing.
In addition, farm crop, plants such as flowers also are not quite similar to the demand of nutrition in the liquid of natural pond, need be according to physiological effect and the nutrition mechanism of natural pond liquid on crop, replenish some useful nutritions, an effective way is exactly that the natural pond liquid after withdrawing deposit is mixed with organic efficiently concentrated composite liquid fertilizer product, enlarge the use range of natural pond liquid, realize the high value added utilization of natural pond liquid, make it have vast potential for future development more aspect non-harmful green agricultural product of production and the flower planting, better improve the liquid fertilizer plant recovery of nutrient, reducing agroecological environment pollutes, agricultural product quality and safety is improved, unlikely entering by food chain produces harm in human body or the animal, and can create remarkable economic efficiency.Therefore filter at normal temperatures, concentrate and separates and prepare organic efficiently concentrated composite liquid fertilizer with the method for physics, form anti-storage, get well transport, easily use, effective commodity introduce that have can creativeness to the market.
Summary of the invention
The present invention is exactly at above-mentioned technical problem, provide a kind of method at normal temperatures natural pond liquid to be filtered at many levels with physics, concentrate and separate and prepare the method and apparatus of organic concentrated composite liquid fertilizer efficiently, produce easy storage, good transportation, easily use, effective liquid fertilizer product, to reduce the labour intensity in the liquid fertilizer application, improve the utilization ratio of liquid fertilizer nutrient, enlarge the range of application of natural pond liquid, promote the growth conditions of plants such as farm crop and flowers and the improvement of growing environment, reducing agroecological environment pollutes, improve agricultural product quality and safety, reduce non-unordered environmental pollution caused by discharge with fertilizer natural pond liquid in period.
For solving the problems of the technologies described above, the present invention realizes according to following step:
1, being provided with liquid precipitate pond, two natural ponds is built in below the ground level respectively, natural pond liquid is process certain hour post precipitation in liquid precipitate pond, natural pond, clarifying natural pond liquid is drawn into natural pond liquid filter vat through liquid precipitate pond, natural pond vacuum primingpump and tentatively filters, the one after the other in parallel of liquid precipitate pond, two natural ponds is used, aspirate more clarifying natural pond liquid in the liquid precipitate pond, natural pond in turn by a natural pond liquid precipitate pond vacuum primingpump and independent by-pass valve control, the pipeline periphery of vacuum primingpump in liquid precipitate pond, natural pond, liquid precipitate pond, natural pond is provided with liquid precipitate pond, natural pond filter screen, intercepts particulate material and enters suction channel and cause connecting tube and liquid precipitate pond, natural pond vacuum primingpump to stop up.
2, natural pond liquid filter vat is to be used for the bigger dregs of filtering particle, material such as vegetable fibre and suspended substance, natural pond liquid after the filtration relies on the liquid deadweight to flow into to store in the former liquid storage tank of natural pond liquid stand-by by natural pond liquid filter vat outlet conduit, natural pond liquid filter vat is provided with natural pond liquid filter vat on-line cleaning device, when the filtering net of natural pond liquid filter vat takes place to stop up, starting natural pond liquid filter vat on-line cleaning device cleans until removing obstruction, behind per tour end-of-job, natural pond liquid filter vat on-line cleaning device in time cleans liquid filter vat inside, whole natural pond, wash the natural pond slag and the natural pond liquid that are bonded on liquid filter vat inside, natural pond and the filtering net, reduce the generation of equipment corrosion and peculiar smell, cleaning sullage enters sewage work and focuses on, and especially summer high-temperature is even more important season.
