Abstract
The invention relates to a biological treatment technology of eutrophic water body, pertaining to environment protection biological technical field. The invention discloses a method of using high effective avirulent alga or photosynthetic bacteria to absorb nitrogen, phosphors and other nutrient inorganic salts in the water body, and helpful planktons such as rotifers, etc. are inoculated to eat off, digest and decompose microalgae and various pathogen with high density in the water body, so as to clear the color of the eutrophic water body and release and even eliminate evil smell of the water body caused by putridity of cell of the microalgae and finally the rotifers and other planktons are the best bait of fishes. The content and the density of the rotifers and other planktons are controlled based on the quantity and weight of the fishes. The nutrients such as N and P that are put into the water body are absorbed by the input photosynthetic bacteria to avoid the microalgae breeding again.
Description
Technical field: present technique belongs to the environment protection biological technical field.
Background technology: along with the raising of people's living standard and human settlement's quality, people are also more and more higher to the requirement of the outside places of cultural interest, greening and the physical environment of residential quarter.Lake, river course and landscape pond are mobile poor, and periphery has sewage to enter, and water during the landscape water body that has adopts causes algal bloom, and water transparency descends, even smelly, destroys the view appreciation effect, even may cause anoxic, makes fish kill.
Treatment process to landscape water body generally comprises second-stage treatment and advanced treatment at present, and independent conventional second-stage treatment is handled the water quality standard that can not reach landscape water body far away with the secondary reinforcement that comprises denitrogenation, phosphorus technology.Especially nitrogen, phosphorus index require to fall far short with landscape water body especially.Advanced treatment mainly remove conventional second-stage treatment impurity in the sewage that can not remove fully, as nutritional type inorganic salt, bacterium, little algae, virus, micro-content organism, heavy metal.Conventional advanced treatment comprises technical matters such as flocculation, precipitation and filtration
[3]Removal process complexity, expensive big, weak effect easily causes secondary pollution.In last decade, membrane bioreactor becomes the new lover of sewage disposal, uses more and more wider.Advantage is need not make with medicament, and removal effect is good.But the cost height, treatment scale is little, and to low molecular weight substance place to go weak effects such as N, P.
Summary of the invention: in fact the process of preventing and treating of eutrophication is exactly to bring out the major control condition that eutrophication takes place by adjusting, restrains eutrophication and takes place.If the employing chemical substance treatment is killed little algae, must cause even more serious chemical substance to be polluted, water pollution is polluted by toxicological harmless become toxic pollution.Therefore, biological treatment is adopted in suggestion, by food chain and eubiosis rule, will pollute removal, and form new tourist sight, avoids simultaneously causing once more and pollutes.Biological control method is the best measure of administering landscape water body eutrophication such as man-made lake.At first adopt high effect nontoxic evil algae or photosynthetic bacterium fully to absorb nitrogen, phosphorus and other nutrition inorganic salt in the water body; Then by useful planktonic organisms such as inoculating rotifers, the little algae and the various pathogenic bacterium of water body middle-high density are eaten up digest and decompose.After little algae was eaten up, when wheel animalcule bait was not enough, mode of reproduction changed syngenesis into automatically by asexual parthenogenesis, produced winter egg, sank under water, and the wheel animalcule that hatching makes new advances when food enriches once more forms the circulation of wave balance of nature.The clear, colorless of wheel animalcule own when no matter moving about, or sinks to the bottom after the death in water, can not influence the color of water.And unsaturated fatty acid content is very high in the wheel polypide, be the outstanding bait of fish and shrimps, if throw in fry and shrimp seedling simultaneously, then without bait throwing in, the growth of fishes and shrimps predation wheel animalcule, wheel animalcule and other microorganism become the best bait of fish, and its content and density are controlled by the quantity and weight of the fish of raising.The N that enters again in the water body, P nutrition are then absorbed by the photosynthetic bacterium of dropping into, and prevent that little algae from growing once more.
Embodiment: biological control method is the best measure of administering landscape water body eutrophication such as man-made lake.At first adopt high effect nontoxic evil algae or photosynthetic bacterium fully to absorb nitrogen, phosphorus and other nutrition inorganic salt in the water body; Then by useful planktonic organisms such as inoculating rotifers, the little algae and the various pathogenic bacterium of water body middle-high density are eaten up digest and decompose.Make the eutrophication water color become clear, and alleviate even eliminates because the water body fouling that the alga cells corruption causes.Last wheel animalcule and other planktonic organisms become the best bait of fish, and its content and density are controlled by the quantity and weight of the fish of raising.The N that enters again in the water body, P nutrition are then absorbed by the photosynthetic bacterium of dropping into, and prevent that little algae from growing once more.Nutrition inorganic salt → little algae or photosynthetic bacterium → wheel animalcule → fishes and shrimps → water are clear, fish guano.
Claims (3)
1. the biologic treating technique of an eutrophication water, present technique is characterised in that
2. adopt and in eutrophication water, drop into zooplankton or their ovum or larvas such as wheel animalcule, cladocera, copepods, will eat up owing to the little algae that grows in a large number that eutrophication causes.
3. adopt and in eutrophication water, drop into photosynthetic bacterium, control growing once more of little algae.
