Description
Technical field
The present invention relates to a kind of method of taming water Magna, also relate to a kind of method for repairing water ecology, specifically a kind of eutrophic water body ecological restoring method.
Background technology
Why blue-green alge is broken out, because the various activities in production 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 nutriments such as nitrogen phosphorus constantly accumulate in a large number in water body, cause unicellular alga, particularly blue-green algae (mainly microcystic aeruginosa) is overflowed, the result of severe contamination water quality.Cells of Blue-green Algae has very flourishing phycocolloid layer mostly, and outside surround by the thick polysaccharose substance of one deck, these phycocolloid and polysaccharose substance almost can not decompose by the digestive ferment of any higher mammal.Therefore, the appearance of blue-green algae biology, has 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 comprise fish and administers blue-green algae pollution, all do not obtain desirable result.
Undoubtedly, Xiang Shuizhong adds chemical herbicide and algae flocculant and can kill precipitation algae very soon.Chemical treatment is the solution solving algae pollution most convenient, but on ecology, this is the worst method, because chemicals and their catabolite finally can be run up in human body by biological chain.Importantly, chemical treatment can not eliminate this basic problem of excessive fertilization, once chemicals is decomposed, dilution, the amount reproduction of algae will occur again, needs 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 a large amount of dissolvings in phosphate.Therefore, the method for blowing aeration can reduce phosphatic solvability and greatly suppress algae reproduction.In the process of biotechnology, water oxygenation is very useful.But single oxygenation can not solve the too much problem of the original nutrient content of water body, the long distance recycle of nutrition causes algal tufa to be appointed so unavoidably.
Microorganism formulation can improve the microorganism in water body and substrate mud, and carries out benign decomposition and the mineralising of organic matter and nutritive element, and some nutritive elements are got 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 of absolute predominance, general microbial treatment can only keep the good working state of 15-30 days, once condition changes (comprise weather, substrate, various water quality condition is as dissolved oxygen, acid-base value, temperature), these microorganism formulations must constantly add, otherwise the outburst of polluting may be more serious.
Algae is nutritious, decomposes rapidly, can be made into good organic manure.But it is too little to salvage mesh needed for algae, and water content is too high again, from the viewpoint of business, the expense of salvaging is higher than the value of organic manure.
As everyone knows, plant waterborne (as weter hyacinth, water peanut, water lettuce, also comprise vegetables waterborne, flowers waterborne etc.) really can absorb nutrient in water body, but their block water 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.
Cladocera (Cladocera) is called for short " Magna class " again, and water Magna is commonly called as red worm, belongs to invertebrate, Crustachia, Branchiopoda, branch angle suborder.As everyone knows, be rich in the harmful substance such as noxious material and poisonous blue-green algae in lake, existing field and with serious pollution water body, the water Magna without domestication is difficult to existence steady in a long-term in seriously polluted, the water body that is rich in noxious material and poisonous blue-green algae in the wild.
