Abstract
A pond blue algae outbreak system establishment method. The invention relates to a blue algae outbreak system establishment method and particularly belongs to the field of blue algae treatment in water treatment of fishery environment protection. The method includes the five following steps: 1) cleaning an aquaculture pond; 2) screening and determining aquaculture varieties; 3) culturing aquatic animals according to specification; 4) performing general cultivation management; and 5) maintaining the pond blue algae outbreak system to hold blue algae outbreak status in the aquaculture pond for years. The pond blue algae outbreak system is used continuously for several years, and several same pond blue algae outbreak systems are combined for performance identification of algae-control tool biology and evaluation on biological invasion risk. The invention provides a test verification system for repeatedly demonstrate a blue algae outbreak process, which is a key technical process and substance fundament for a novel technology of quickly and high-effectively screening and controlling algae. The method can solve development difficult problems and verification problems demanded in the blue algae treatment technology.
Description
Technical field
The present invention relates to a kind of blue algae bloom system constituting method, specifically belong to fishery environment-protective water and process blue-green algae improvement field. PondBlue algae bloom system is a kind of verification experimental verification system that can repeat to demonstrate blue algae bloom process, be rapidly and efficiently filter out control algae newKey technique of technology and material base, can solve the required exploitation difficult problem of blue-green algae improvement technology and a checking difficult problem.
Background technology
Eutrophication process and blue-green alga bloom outburst are the results of various water environment factor interactions, and water environment condition causes blueAlgae outburst, blue algae bloom also can change Water Factors, is therefore a kind of process of mutual cause and effect, forms plus or minus feedback and doesWith state, cause lake eutrophication wayward, the blue-green algae problem of the spreading unchecked the difficult problem of environmental protection that becomes international for a long time.
From ecosystem structure, cyanobacteria is that the microorganisms such as blue-green algae are primary producer, and analyst especially, at nutritive saltFlow and material recycle process in play an important role. Autumn in summer high temperature season, the long-term mistakes of nutrient such as nitrogen, phosphorus, organic carbonDegree accumulates in waters bottom, and aerobic organic matter increases, and causes body eutrophication aggravation, and water quality deterioration causes that algae etc. swimsBiological rapid propagation, especially taking Microcystis aeruginosa spread unchecked as main harmful algae grows in a large number (be commonly called as " wawter bloom ", patina water,Blue-green alge etc.), have a strong impact on the normal growth of aquatic animal, threaten hydrobiological health, destroy aquatic ecological.
In the natural water area systems such as lake, blue-green algae is spread unchecked problem and perplexs for a long time water prevention and cure of pollution worker. China carries out in recent yearsComprise: sewage dams, ecological dredging, move back also also water, restoration of the ecosystem of lake, power of fishing, loke shore regulation and the construction of Huan Hu forest beltDeng Water Environment In Lakes regulation action, try hard to reach control blue-green algae by ectogenic regulation and control and spread unchecked, improve the object of water quality, performanceCertain effect. But basic method should be to use endogenous means, utilizes aquatic animal to carry out restoration of the ecosystem, control blueAlgae is spread unchecked, and repairs and rebuilds water ecosystem, recovers water ecosystem structure, realizes the multi-functional service valency of water body in lakeValue, maintains and stablizes healthy aquatic ecosystem, can reach the inaccessiable object of exogenous means.
In common a few class endogenous algae control methods, (1) microbial method: can promote blue-green algae rot and be decomposed at natural water,Nutriment is got back in water, there is no endogenous Reduction of Students' Study Load, and has ecological risk; (2) crustacean method: laboratory test effect is pretty good,But difficulty is cultivated in a large amount of industrialization, form and to maintain suitable population density particularly difficult; Lack continuation, need regularlySupplement. As: algivorous insect. (3) water plant method: in Taihu Lake, Dian Chi carries out pilot scale application, but can only absorb little after corruptionMolecular substance, Eutrophication materials will experience putrefactive fermentation and discharge stink process, has brought spreading unchecked of planting plants simultaneously, bandCarry out plant product and processed a difficult problem. As: water hyacinth, waterweed etc. (4) mollusk method: the digestion blue-green algae that can directly eat,Before corruption, transformed and utilized, being reduced pollution sources, being produced new good protein resource. As: the softwares such as spiral shell, a species of small clam living in fresh water, freshwater musselAnimal, but lack initiative while causing processing blue-green algae because of its relative settling down property. (5) non-classical bioanalysis: directly eat, in corruptionBefore losing, transformed and utilized, being strengthened elementary conversion capability etc.; Because silver carp bighead is incomplete without peptic digest blue-green algae, can only process floatingThe algae in stage. As silver carp bighead, Xie Jaw silver xenocypris etc. These a few class algae control methods, for want of blue algae bloom system of specification, is difficult to straightThe qualitative, quantitative of seeing is relatively controlled difference and the quality between algae technology, is difficult to judge the technique effect between endogenous control algae technical method.
Water pollution control field people in the industry all thinks, select good, efficiently to control algae instrument biology be blue algae control and improvement fieldKey link and approach; But selection tool biology also needs to build and standardization blue algae bloom system, blue algae bloom system is control algaeThe requisite link of technological progress; But cannot simulate all envirment factors of blue algae bloom in laboratory, set up blue-green algae quick-friedThe system of sending out is difficult, and required environmental condition fails to determine, is difficult to the structure blue algae bloom system of controllability, replicability;Laboratory system often can not meet the life growth conditions of control algae instrument biology, is difficult to carry out control algae instrument biology and control algae technologyThe screening of scheme; Laboratory system's natural water area system difference of unifying is too large, and laboratory technique will face again in the time that natural water area usesThe problem that correction and pilot scale are adjusted, becomes restriction control algae technological development and perfect key link. Lack blue algae bloom system, justLacked approach and the place of relatively controlling algae technology quality, intuitively the comparison of science and rapid screening go out efficient control algae technical sideCase, causes lake blue algae to administer technical progress slow, and the lake blue algae problem of spreading unchecked is still the international headache in industry.
Summary of the invention
The object of the invention is to overcome blindness in blue-green algae improvement field control algae technology screening process, the shortage of blue algae bloom system,Cannot carry out contrast test between blue algae control technology, checking, the link such as perfect; Cause controlling shortage of standard between algae technical scheme, difficultyTo control the technology spies such as algae purified treatment efficiency, control algae effect quality, persistence stability between the standard comparison techniques with commonPoint, thereby the lake blue algae problem of spreading unchecked is still the international headache in industry.
