Description
Technical field
Thing During High-Temperature Composting is salvaged the present invention relates to a kind of lake and protects nitrogen method, belongs to resource circulation utilization technical field.
Background technology
Accumulation precipitates for a long time for nitrogen, phosphorus etc. in mud under lake and periphery riverbed, is the main original for causing lake eutrophication
Therefore one.Polluted bed mud is dredged, oneself, which turns into, improves one of lake water quality, the effective way for recovering lake ecological.
With increasingly sharpening for freshwater lake body eutrophication, the lake of Blue-green Algae Fast Growth is also more and more.Salvage
Blue-green algae as handled not in time, secondary pollution will certainly be caused.
Water hyacinth also known as Eichhornia crassipes, there is extremely strong absorbability to nitrogen phosphorus nutrient and toxic element in sewage, can be
Largely enrichment Water, phosphorus and detection device for multi metallic elements in a short time, so as to play the effect of fast purification water body, so by water
The technology that cucurbit is used to repair body eutrophication is at home and abroad widely used.But water hyacinth fertility is extremely strong, 1 plant
Water hyacinth can just multiply the colony into 600,000 plants for 8 months, and the so huge water hyacinth of quantity, which is dealt with improperly, will block river course, become silted up
Aggravate body eutrophication after Integral Solution.
At present, all there are a large amount of soils of occupancy in the mud for either salvaging blue-green algae or desilting, cause asking for secondary pollution
Topic.Meanwhile as the ecological engineering of lake plantation water hyacinth abatement water nutrition is implemented, it will a large amount of water hyacinth residuums are produced,
Also the problem of same will be faced.The water hyacinth of the blue-green algae salvaged with recycling, mud and plantation is how effectively disposed, is mesh
The problem of preceding urgent need to resolve.
Using the blue-green algae of salvaging, the water hyacinth During High-Temperature Composting of mud and plantation can effectively dispose and recycling, but compost
During be easier to lose nitrogen, its approach be ammonium nitrogen be converted into NH3、NOxDischarge, makes the nutrient of compost reduce, while can also pollute
Environment.Therefore, guarantor's nitrogen technology during During High-Temperature Composting, it is always the focus of domestic and foreign scholars research.
The content of the invention
The technical problems to be solved by the invention：For the blue-green algae currently with salvaging, the water hyacinth of mud and plantation is high
It is easier to lose nitrogen in warm composting process, its approach is that ammonium nitrogen is converted into NH3、NOxDischarge, makes the nutrient of compost reduce, while
The problem of polluting the environment, the invention provides a kind of high temperature insulation paper and preparation method thereof.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
Salvage thing During High-Temperature Composting and protect nitrogen method in a kind of lake, it is characterised in that specifically preparation process is：
（1）By raw material dehydration desiccation micronization processes, pretreated water cucurbit, pretreatment blue-green algae, pretreatment dredging silt, pre- place are prepared
Manage soybean nodulation, pretreatment vinegar grain；
（2）By ferrous sulfate, sodium humate, calcium superphosphate, pretreatment vinegar grain, pretreated soybean root nodule, pretreated water cucurbit, pre-
Processing blue-green algae, pretreatment dredging silt, which are fitted into spice bucket, to stir, and obtains compound material；
（3）Compound material is fitted into compost case and covers layer of plastic film, compost 40~60 days, every turning in 7 days 1 time,
And deionized water is added, it is 60~65% to control water content, obtains lake and salvages organic fertilizer.
The pretreated water cucurbit be by water hyacinth dry be 50~60% to water content after be fitted into Material disintegrator, shred to 1
~3cm fragment is made.
The pretreatment blue-green algae is that to dry blue-green algae to water content be 60~70% to be made.
The pretreatment dredging silt is that dredging silt is fitted into press filtration in filter press, and it is 40 to dry to mud water content
~50% is made.
The pretreated soybean root nodule is natural air drying after soybean nodulation is washed with deionized into 2~3 times, then is transferred to powder
Crushed in broken machine, cross 40 mesh sieves and be made.
For the pretreatment vinegar grain for vinegar grain is fitted into drying box, it is 30~40% to be dried at 40~50 DEG C to water content,
Dried vinegar grain is fitted into pulverizer again and crushed, 40 mesh sieves is crossed and is made.
The ferrous sulfate, sodium humate, calcium superphosphate, pretreatment vinegar grain, pretreated soybean root nodule, pretreated water calabash
Reed, pretreatment blue-green algae, the parts by weight that pre-process dredging silt are 60~70 parts of ferrous sulfate, 15~20 parts of sodium humates, 5~8
Part calcium superphosphate, 200~300 parts of pretreatment vinegar grains, 100~200 parts of pretreated soybean root nodules, 1200~1500 parts of pretreated waters
Cucurbit, 1200~1500 parts of pretreatment blue-green algaes, 600~800 parts of pretreatment dredging silts.
The method have the benefit that：
（1）The present invention adsorbs nutrient or filling heap body space by adding pretreated soybean root nodule and pretreatment vinegar grain, to be thermophilic
The activity of microorganism provides good microenvironment, makes microorganism amount reproduction in a short time, and then promotes organic matter degradation heat production,
The toggle speed and maturity of compost reaction are accelerated, composting process is entered stationary phase in advance, and then shorten needed for compost
Time, meanwhile, by pre-process vinegar grain adjust heap body water content maintain 60%~65%, be compost maturity during microorganism
Breeding and metabolism provide optimal hydrothermal condition and suitable acid-base value, microorganism is effectively played a role, in composting process
The addition of nitrogen protecting agent reduces the ammonia loss by volatilization of heap body, so as to retain the available nitrogen in heap body, simultaneously effective alleviates sky
Gas peculiar smell, serve deodorization and the effect of environmental protection；
（2）The present invention reduces heap body pH using vinegar grain, ferrous sulfate, calcium superphosphate is pre-processed, and increase compost is nitrogenous organic early stage
Thing converts ammonification, reduces compost hot stage ammonia volatilization amount, while utilize the ionizable generation metal cation of ferrous sulfate, mistake
Calcium phosphate hydrolyzable produces H+, NH can be broken3And NH4 +Between balance, nitrogen is mainly existed in the form of ammonium salt and is dropped
Low NH3Volatilization, meanwhile, excessive Fe2+Complex reaction can also occur with nitrogenous class water soluble organic substance with humic acid group, generate ammonia
Class complex compound, the process that organic nitrogen in water hyacinth composting process is converted into inorganic nitrogen is further suppress, recycle soybean nodulation
Bacterium activates inorganic nitrogen, strengthens organic fertilizer nitrogen absorptivity, improves organic fertilizer fertility, and the organic fertilizer being easily absorbed by plants is made, has
Wide application prospect.
