Abstract
The invention relates to a method for controlling cyanobacterial bloom, which is mainly characterized by throwing composite biological strains, trace elements and filter-feeding fishes into a water body so as to rapidly construct a beneficial bacteria-algae cycling system of the water body, fundamentally lower the eutrophication degree of the water body and and achieve the goal of thoroughly controlling the cyanobacterial bloom. The invention is suitable for the ecological management of various eutrophy water bodies and has simple operation, low cost, rapid management and obvious effect.
Description
Technical field
The present invention relates to biological and ecological engineering of environment field, be specifically related to a kind of method of controlling blue-green alga bloom.
Technical background
Blue-green alga bloom is a kind of because the water contamination phenomenon that the excessive breeding of blue-green algae that nutritive substance surpluses such as nitrogen, phosphorus cause in the water body causes.Follow blue-green alga bloom to occur simultaneously, also have a series of phenomenons such as the severe exacerbation of water quality, water ecosystem destroy, water body emits bad smell, ecotope is caused seriously influence.At present, the improvement method to blue-green alga bloom mainly contains physics method, chemical method and biology (ecology) method three major types.Biological process becomes the important means that blue-green alga bloom is administered at present just gradually because of ecology, the environment-friendly advantage of uniqueness.Current biological treating blue-green alga bloom method commonly used, mostly be to take technical measures such as plant purification, microbial augmentation, microbial film processing, but these method ubiquities take effect slowly, and the cost height can not fundamentally reduce body eutrophication, can not solve the problem of blue-green alga bloom at all.
Summary of the invention
Administer the multinomial weakness of blue-green alga bloom for overcoming present biological process, the invention provides a kind of method by the optimum bacterium algae of in-situ construction water body circulating system, not only can fundamentally reduce water body eutrophication degree, also can improve the quantity of useful algae greatly, improve the water body dissolved oxygen amount, improve water body self-purification ability, thereby thoroughly control blue-green alga bloom.The inventive method is simple, and cost is low, effectively original position improve water quality, make up optimum bacterium algae circulating system.
The technical scheme that the present invention overcomes biological process improvement blue-green alga bloom problem is:
1. the input of complex microorganism bacterial classification;
After the complex microorganism bacterial classification was thrown in secondary nutrition water body, self carried out rapid growth and breeding, by respiration, absorbed the oxygen in the water body, and the nutritive substance that absorbs in the water body carries out decomposition and inversion, emitted CO simultaneously
2,, thereby promote the ramp of useful algae for useful algae such as aquatic plant plankton etc. provide growth necessary carbon source.
2. Wei Liangyuansu input;
Trace element provides essential material for the growth of plant plankton on the one hand, has promoted absorption and the transformation efficiency of useful algae to nutritive substance such as nitrogen, phosphorus in the water body on the other hand, thereby can fundamentally reduce nitrogen, phosphorus content in the water body.Useful algae absorbs CO by photosynthesis
2, and a large amount of nutritive substance that transforms in the water body that absorbs, self emit O simultaneously
2So not only improve the dissolved oxygen amount in the water body greatly, strengthened water body oneself purification function, and provide necessary material for the respiratory metabolism of microbial strains.In the water body system, just formed the benign cycle system between complex microorganism bacterial classification and the useful algae like this.Along with the continuous reinforcement of bacterium algae circulating system function, the nutritive substance in the water body is by mass consumption, and water body is excessive to poor nutritional status by eutrophic state gradually.Useful algae finally by nutrient competition, is effectively controlled blue-green alga bloom, finally improves water quality.
3. input filter-feeding fish.
For avoiding the excessive multiplication of useful algae in the water body, suitably throw in filter-feeding fish and control amount of algae, be the requisite measure of guaranteeing the benign development of bacterium algae circulating system.After throwing in the certain period, fish are salvaged, the dried up body of nutritive substance band in the water body has improved cultured output simultaneously the most at last.
The invention has the beneficial effects as follows: the invention provides and a kind ofly make up water body probiotics algae benign cycle system fast, fundamentally reduce the water eutrophication degree methods, thereby blue-green alga bloom is effectively controlled by original position.The present invention also is applicable to the ecological management of multiple eutrophic water body, instant effect, and effect is remarkable, administers thoroughly, and is easy to operate.
Embodiment
Implementation step of the present invention is:
1. in water body, throw in microbial strains and trace element.According to the water quality detection situation of water body, calculate bacterial classification and the micro-dosage that should throw in, regularly carry out the detection of water quality, in conjunction with detection case, adjust in good time.The microbial strains of throwing in is compound freeze-drying lactobacillus, and the trace element of throwing in is the strong organic complex of solubility.
The complex microorganism bacterial classification comprises one or more in milk-acid bacteria, Lactobacterium acidophilum, plant lactobacillus, subtilis, streptococcus faecium, streptococcus faecalis, lactobacterium casei, pediococcus acidilactici, bifidus bacillus, bacillus natto, yeast, photosynthetic bacterium, Rhodopseudomonas palustris, the Bacillus licheniformis.Between 0-70 ℃ of temperature, after cultivation 1-3 on the special culture medium days, add lyophilized vaccine, freeze-drying under-20～-40 ℃ freeze-drying environment, packing then.
Trace element comprises one or more in copper, iron, zinc, manganese, silicon, calcium, molybdenum, sodium, the potassium element.Trace element adopts inorganic salt and polyphenol carboxylic acid cpd, EDTA, catalyzer, emulsifying agent, solubility promoter and water to carry out chelatropic reaction under certain condition and makes.Obtained inorganic salt have good water-solubility, can slowly continue to discharge nutritive element for the recycle of bacterium algae in water body.
2. input filter-feeding fish.According to the water body situation, throw in the filter-feeding fish of some amount, as silver carp.Put laggard pedestrian worker of for some time in a suitable place to breed and salvage, nutritive substances such as final nitrogen, phosphorus leave water body.
3, water quality obtains the improvement of essence.
The embodiment explanation
About 5000 mu of certain freshwater lake area, storage capacity is about 9,000,000 cubes, about 3,000,000 cubes/year of dynamic flow.Be subjected to all kinds of blowdowns and the pollution effect of peripheral surface source in recent years, be serious eutrophication state.2008, use the inventive method after 2 months, ammonia nitrogen reduces 68.2% in the water body, the total phosphorus range of decrease 41.1%, nitrogen removal rate 36.4%, COD has reduced by 70%.In addition, the plant plankton cell density (645.9 * 10 after the processing
4Cells/L), than check plot (1144.96 * 10
4Cells/L) low 43.6%; Blue-green algae in the plant plankton, the ratio in treatment group is 46%, the ratio in control group is 65%, blue-green algae ratio treatment group ratio
