Abstract

At first, breeding filter feed silver carp, carp and crucian carp in area of water bloom breakout to control algae growing; pelagian eats small algae to reduce quantity of the algae; spiral shell and clam can moves carrying roes toincrease fish spreading area; cyanophage, dissolved algae bacteria and other microbe eating algae are separated and purified from natural water, which is cultured to large quantities in laboratory then to be put in blue algae water bloom breakout orea to control algae; resumption of water plant in water bloom breakout area can control algae growing. Last is getting rid of algae by machine including fixed blue adgae water bloom removing machine and mobile blue adgae water bloom removing machine.

Description

A kind of method of controlling blue-green alga bloom
Technical field
The present invention relates to biological and ecological engineering of environment field, more specifically relate to a kind of method of controlling bloom blue algae.
Background technology
Body eutrophication is a global environmental problem, and the situation of China's fresh water body eutrophication is very severe.Body eutrophication cause algae particularly blue-green algae breed unusually, water transparency and dissolved oxygen descend, water quality deterioration; In the lake of eutrophication, hydrobiological group, population structure can change.Eutrophication causes serious harm to aquaculture, aquatic organism heritable variation, agricultural irrigation and view tourism etc.
At present, there is a lot of eutrophic lakes in China, and as the Taihu Lake of jiangsu wuxi, Chaohu of Hefei ,Anhui, the Dian Chi in Kunming, Yunnan etc., they all have blue-green alga bloom in various degree to break out in different seasons.The method of administering blue-green alga bloom is a lot, chemical method is arranged, biological process, biochemical process or the like.Although the improvement method is a lot, all is to deal with problems from apparent, cure the symptoms, not the disease, not dealing with problems in essence at blue-green alga bloom.The key that blue-green alga bloom breaks out control is to control the productivity of blue-green algae! The method of therefore administering blue-green alga bloom can not be single, can not will get up to utilize each method synthesis with the method for destroying aquatic attitude structure and function, could administer blue-green alga bloom completely.
Summary of the invention
The object of the present invention is to provide a kind of method of controlling blue-green alga bloom, this is easy to implement the method, can administer water effectively and pollute the governing problem of more effective solution blue-green alga bloom.
In order to achieve the above object, the present invention has adopted following technical measures:
1. putting in a suitable place to breed of filter-feeding fish and other fish, as, silver carp, bighead, carp, crucian.At 6.1km 2The test site in put 220 tons of filter-feeding fishes in a suitable place to breed because growth, disease and the artificial factor of fish can make the breeding density of fish change,, fish for or replenish so require regular fish is investigated, make and put fish density and remain on same level.
2. the adding of zooplankton, as, wheel animalcule, cladocera, copepods and protozoon.The zooplankton common at the test site water body has wheel animalcule, flea and Magna.The feeding habits of most of zooplankton are filtration type, can be from water the leaching unicellular algae.
3. the input of spiral shell, freshwater mussel.At 6.1km 2The test site throw in totally 10.4 tons of spiral shell, freshwater mussels, spiral shell, freshwater mussel can be carried the fish-egg motion, and the distributed areas of fish are increased.
4. the microorganism of phycophage, molten phycomycete and other algae that eats is spilled into.Separation and purification is come out in the test site water, and enlarged culturing is sprayed onto in the lake again.As, haematococcus.
5. the recovery of aquatic vegetation.Comprise floatingleaved plant and submerged plant in the lake, as water caltrop, Herba potamogetonis distincti, water caltrop, eel grass, red line grass, black algae, watermifoil; With the emergent of coastal belt, as cattail, reed, willow.
6. machinery removes algae.Machinery removes algae fixed blue-green alga bloom clearing device and portable blue-green alga bloom clearing device.Operating process is similar substantially: the enrichment of blue-green alga bloom, algae, the filtration of vibration slanted screen, algae slurry, centrifuge dehydration, algae slurry.
More than six kinds of method synthesis utilizations, make the whole ecological system keep balance, can more effective improvement blue-green alga bloom problem.
The present invention administers with existing blue-green alga bloom and compares, and following advantage and unusual effect are arranged: easy to implement the method, can thoroughly effect a radical cure wawter bloom, make water quality improve, economical quick, utilization and extention on a large scale.
Embodiment
A kind of method of controlling blue-green alga bloom is specifically implemented as follows:
1. put the silver carp bighead of filter-feeding and carp, crucian in a suitable place to breed in the zone of breakout of water bloom, they are food with the algae, reduce the quantity of algae, thereby reduce the productivity of blue-green algae, play the purpose of control algae.At 6.1km 2The test site in put 220 tons of filter-feeding fishes in a suitable place to breed because growth, disease and the artificial factor of fish can make the breeding density of fish change,, fish for or replenish so require regular fish is investigated, make and put fish density and remain on same level.
2. zooplankton is a food with small-sized algae, also can reduce the quantity of algae.Cultivate zooplankton wheel animalcule common in the test site water body in the laboratory in a large number, flea and Magna put into the zone of breakout of water bloom then, for the control algae plays part effect.
3. spiral shell, freshwater mussel can be carried the fish-egg motion, and the distributed areas of fish are increased.Spiral shell, freshwater mussel itself also can reduce the quantity of algae.At 6.1km 2The test site throw in totally 10.4 tons of spiral shell, freshwater mussels, also require to fish for or replenish.
The microorganism of phycophage, molten phycomycete and other algae that eats all in natural water separation and purification come out, so these phycophages and molten phycomycete can not impact ecotope.In the laboratory, after a large amount of the cultivation, put into blue-green alga bloom outburst zone again, play the effect of control algae.In enclosure, demonstrate earlier, effective, be generalized to full lake again.
5. the recovery of breakout of water bloom zone waterplant also can be played the effect of control algae.Breeding floatingleaved plant and submerged plant in the lake are as water caltrop, Herba potamogetonis distincti, water caltrop, eel grass, red line grass, black algae, watermifoil; Coastal belt breeding emergent, as cattail, reed, willow.
6. machinery removes algae fixed blue-green alga bloom clearing device and portable blue-green alga bloom clearing device, and their technical process is successively: the enrichment of lake surface blue-green alga bloom fence, Algae absorbing device collection, algae, algae water gravity slanted screen filter flash trapping stage, algae slurry, algae water horizontal screw centrifuge dewaters, and secondary separates, algae mud.
More than six kinds of method synthesis utilizations, the productivity of control blue-green algae, the structure that makes the whole ecological system keeps benign state with function, therefore the more effective improvement blue-green alga bloom problem of energy.
