Description
Technical field
The invention belongs to biogas slurry treatment technical field, relate to a kind of biogas slurry purifying aquaculture, special
It not a kind of biogas slurry optical processing cultivating system and operational method thereof.
Background technology
Biogas slurry, be otherwise known as " anaerobic fermented liquid ", is the organic matter such as animal wastes, straw
After anaerobic fermentation, residual has water miscible by-product.Along with agricultural structure is adjusted
Whole and new countryside construction, intensive livestock and poultry breeding industry fast development, send out as biogas anaerobic
Product biogas slurry after ferment, these waste liquids are used as agriculture fertilizer or directly discharge, seldom considering row
Whether and safety for agricultural use unconventional and unrestrained mark.It practice, biogas slurry still contains after anaerobic digestion
Substantial amounts of nitrogen, phosphorus and metal, be considered high-concentration sewage.
The biogas utilizing organic solid castoff anaerobic digestion to produce is that a kind of clean type is biological
Mass-energy source, but anaerobic digestion solution generation amount is relatively big, the natural pond that the annual biogas engineering of China produces
Liquid reaches more than 200,000,000 ton, and anaerobic digestion solution post processing problem has become restriction biogas industry development
One of Main Bottleneck.At present, anaerobic digestion solution is typically used as agriculture fertilizer or directly discharges,
Seldom consider that whether and agricultural safety emission compliance.It practice, after anaerobic digestion
Biogas slurry still contains a considerable amount of organic pollution, wherein BOD (BOD),
COD (COD), float (SS), ammonia nitrogen (NH 3-N), total phosphorus (TP),
The biggest to the pressure of environment.Therefore, it is necessary to investment in research and development is low, energy consumption is low, high
Effect biogas slurry is innoxious and resource treatment technique, to solve the bottleneck problem of biogas fermentation,
Realize resource circulation utilization.
Method for the treatment of city waste water is continued to use in the purification method research of biogas slurry more, use physics,
The method such as chemical, biological, such as natural ecological resource methods such as biological pond method and artificial swamps and

Its clear liquor sequentially enters acid-alkali accommodation pond, according to the soda acid of soda acid detector monitors biogas slurry
Degree, then according to required acid-base value standard, controls flow valve and opens, pass through regulating agent
Case injects proper amount of medication in biogas slurry, and unlatching stirring paddle is stirred operation and makes biogas slurry simultaneously
Concentration is consistent, can enter lettuce, acid-base value and nutritional labeling in acid-alkali accommodation pond
Row regulation；
5) biogas slurry, after overregulating is in the further precipitated impurities in acid-alkali accommodation pond, then
Its clear liquor sequentially enters algae culture pond, the algae root being grown in algae culture pond plant into
In culture medium, and being fixed by the cover layer on upper strata, algae is solid under photosynthesis
Determine the carbon dioxide in biogas, and utilize the inorganic salts such as the inorganic nitrogen in biogas slurry, phosphorus for battalion
The source of supporting growth and breeding, realizes the water body purification of biogas slurry simultaneously；Carried by the first regulation fluorescent tube
For intensity of illumination in various degree, control water temperature by the first electric thermostat, and then strengthen
Algal grown is bred；Utilization is cut algae assembly and is periodically cut algae top, under cutting
Algae leaf enter next process pool as feedstuff along with the water body purified；
6), biogas slurry complete to purify and last precipitation in algae culture pond, then it is clear
Clear liquid sequentially enters animal culture pond, opens water-change pump, is cultivated to animal by water-changing tube
Chi Bengshui, had both supplemented institute's water requirement, and had suitably diluted lettuce again, open simultaneously
Open pump oxygen machine and in animal culture pond, provide oxygen, in animal culture pond by oxygen supplying tube
Use algae leaf as main feed, coordinate suitable auxiliary feedstuff, provided by the second regulation fluorescent tube
Intensity of illumination in various degree, controls water temperature by the second electric thermostat, and then strengthens water
Flat growth and breeding；Periodically turn on sewage draining exit miscellaneous with residue, the Excreta deposited at the bottom of discharge pond
Matter.
In above-mentioned operational method, in step 1) in, disinfectant solution is concentration 8～10%
Liquor natrii hypochloritis, its addition is 1～3mL/L, thereafter with the sulfur of same concentrations for sulfur
Acid sodium neutralizes, described sodium hypochlorite stock solution effective chlorine content % >=10.0.
In above-mentioned operational method, in step 2) in, by biogas slurry in resolution process pond
The biogas that middle metabolism is formed is collected, and then absorbs the methane content in biogas and removes
Stink, then by Pipeline transport to algae culture pond, so that remaining carbon dioxide in biogas
Gas helps algae reproduction growth.
In above-mentioned operational method, in step 3) in, aeration process is specially and adds
The quick lime of water body volume 0.3～0.5 ‰, after continuous aeration 24h, is spaced 3 hours again
Continuous aeration 24h, precipitates 2h.
In above-mentioned operational method, in step 6) in, animal culture pond is by dividing
Become multiple independent isolation cultivation region, cultivate fairy shrimp, Limnodrilus hoffmeisteri, Bellamya quadrata and sight respectively
Reward fish.
Compared with prior art, this biogas slurry optical processing cultivating system and operational method thereof utilize
Biogas slurry has the nitrogen phosphorus inorganic salt of high level, thus using after biogas slurry treatment as algae
Nutrition provides the energy, simultaneously using the carbon dioxide in biogas as algae culture raw material, both
Solve the Cost Problems that algae is cultivated, purify again and make use of biogas, biogas slurry, also reduce
The environmental pollution of biogas slurry, carries out the raising of animal further by algae reproduction, optimizes
Animal feeding water quality, also provides for feedstuff, economization feeding cost, reaches supporting of circular biological
Grow industry, and reach to improve environment, increase economic, society and the purpose of ecological benefits.
The heat and the ultraviolet that use lamp carry out sterilizing, effectively profit simultaneously to biogas slurry
Environmental protection and energy saving are realized with green energy resource；Use artificial lighting also can realize illumination at night to make
With, use artificial homoiothermic to ensure water temperature constant demand, be effectively improved the life of algae and Aquatic product
Grow effect.
