Description

Tame large-scale method and method for repairing water ecology
Technical field
The present invention relates to two kinds of large-scale methods of domestication, further relate to two kinds of method for repairing water ecology, especially a kind of eutrophic water body ecological restoring method.
Background technology
Why blue-green alge is broken out, it is because the various production activities of the mankind, to river, the discharge into water nitrogen such as lake, phosphorus nutrition material, when lake ecological self-purification capacity is destroyed, the nutrient substance such as nitrogen phosphorus constantly accumulate in a large number in water body, causing unicellular alga, particularly cyanophyceae (mainly microcystic aeruginosa) is overflowed, the result of severe contamination water quality.Cells of Blue-green Algae has very flourishing algin layer mostly, and outside is surrounded by the polysaccharose substance that thick layer is thick, and these algin and polysaccharose substance are little to be decomposed by the digestive enzyme of any higher mammal.Therefore, the appearance that cyanophyceae is biological, almost become the cecum of food chain and biological chain.The expert of domestic and international many environmental protection and biological aspect adopts higher mammal to include Fish and administers cyanophyceae pollution, does not all obtain desirable result.
Undoubtedly, in water, add chemical herbicide and algae flocculant can quickly kill precipitation algae.Chemical treatment is the solution solving algae pollution most convenient, but on ecology, this is the worst method, finally accumulate into the human body because chemical drugs and their catabolite can pass through biological chain.It is essential that chemical treatment can not eliminate this basic problem of overnutrition, once chemical drugs is decomposed, dilution, the amount reproduction of algae will occur again, it is necessary to continual chemical treatment.
When dissolved oxygen height, phosphate usually crystallization forms undissolved chemical combination state;And when dissolved oxygen is on the low side, will there is substantial amounts of dissolving in phosphate.Therefore, the method for blowing aeration can reduce phosphatic dissolubility and significantly suppress algae reproduction.In the process of biotechnology, water oxygenation is highly beneficial.But, single oxygen supplement can not solve the problem that the original nutrient content of water body is too much, and it is so inevitable that the distance recirculation of nutrition causes that algal tufa is appointed.
Microorganism formulation can improve the microorganism in water body and substrate mud, and carries out benign decomposition and the mineralising of organic matter and nutrient, makes some nutrients get off with inertia form temporary stabilization, and its result is similar to the method for blowing aeration.It should be noted that, the existence of microorganism is inherently decided by culture environment, and requiring the population having absolute advantages, general microbial treatment can only keep the good working state of 15-30 days, once condition changes (includes weather, substrate, various water quality conditions such as dissolved oxygen, acid-base value, temperature), these microorganism formulations must constantly add, and the outburst otherwise polluted may be more serious.
Algae is nutritious, decomposes rapidly, can be made into good organic fertilizer.But needed for salvaging algae, mesh is too little, and water content is too high again, from the viewpoint of business, the expense of salvaging is higher than the value of organic fertilizer.
It is known that, plant waterborne is (such as Herba Eichhorniae, water peanut, water lettuce, also include vegetable waterborne, flowers waterborne etc.) really can absorb the nutrient in water body, but they block waters surface, hide sunlight, cause at the bottom of part aquatic organism and mud biological, the particularly death of submerged plant, causes a large amount of dissolvings of Middle nutrition salt at the bottom of mud then, and their drawback is far longer than the benefit that they bring.
