Description

A kind of breeding method of algae removal worm
Technical field
The present invention relates to ecological restoration technical field, and in particular to a kind of breeding method of algae removal worm.
Background technology
As the development of industrial or agricultural, the growth of population and people are for the demand of more high standard of living, the discharge capacity of waste water It is continuously increased.A kind of important sign that body eutrophication phenomenon is on the rise is that the extensive of algal bloom breaks out, wherein, most Common is exactly blue-green alga bloom.The outburst of blue-green algae can form one layer of blue-green in the water surface and have the offscum of fishy smell, cause water quality to be disliked Change, exhaust water oxygen when serious and cause the death of fish.Water PH value can be caused drastically to be increased to 9.5 during blue-green algae peak Cause alkalosis above, strengthen the toxicity of ammonia nitrogen, cause water body animal poisoning etc..Algae control technology mainly has thing in lake at present Logos, chemical method and Antimicrobial algae, animal predation method, bio operon method etc..But the method for ecology is trend of the times, more It is safe, more stable, more longlasting, it is more attractive.
Existing method mainly changes its enteric microorganism composition using taming Magna, reach can digest the ability of blue-green algae so as to Purify water;Or Daphnia magna is cultivated, and goals of investment water body after being tamed with blue-green alge powder.Phytoplankton is divided into Cladocera, Copepods, wheel animalcule and protozoan.Currently used is the cladocera of single variety, is because cladocera is to swimming Plant, that is, food rate is higher is herded to algae, but the zooplankter in different waters composition is different, and zooplankter Adaptability to different water bodys is different, and administering water environment using the waters of same species at different conditions may Cause the problems such as inadaptability, the survival rate of zooplankter are low, regulation effect is poor.
Based on this, there is provided a kind of breeding method of algae removal worm.
The content of the invention
It is an object of the invention to:For the method for existing cultivation algae removal worm, using fixed kind algae removal worm to all water The wawter bloom in domain is administered, and the algae removal worm turned out is relatively low to water body adaptability and viability, is unable to reach expected net Change effect, it is proposed that a kind of breeding method of algae removal worm, according to the theory of " original seed controls raw water ", separated using the water of target water body Go out algae removal worm colony and algae kind, then by inoculating and culturing out the algae removal worm come, can be more easy to adapt to water body, survival rate is high, algae removal speed Degree faster, solves algae removal worm in the prior art and does not adapt to water body, and survival rate is low, except technical problems such as algae effect differences.
The present invention is achieved through the following technical solutions:
A kind of breeding method of algae removal worm, including following operating procedure:
1) BG-11 culture mediums are configured;
2) aeration 3d running water 150L is respectively placed with two containers;
3) waters will be administered as target water body, take upper, middle and lower each 10L of layer water body to be mixed, and be concentrated into 50ml, it will be beneficial in 50ml water bodys except the macrozooplankton of algae and phytoplankton sociales are separated;
4) zooplankter in step 3) is placed in container one, phytoplankton is placed in container two;
5) BG-11 culture mediums are added in container two and growth culture is carried out to the advantage algae kind of separation;
6) algae in container two is dragged in container one daily, injected volume is incremented by by 6%, continuous 5-8d, by taming, washing in a pan Zooplankter dominant population after eliminating is algae removal worm;
7) algae removal worm is dispensed, repeats the above steps and carry out growth culture;
Prior art cultivate algae removal worm method be:Next algae removal worm varities practice is turned out into all water in fixed waters In the purification of water quality processing in domain, because algae kind is different in each waters, algae removal worm can not preferably adapt to water body, and survival rate is low, The technical program is used to cultivate algae removal worm using the water body in improvement waters as target water body, and the algae removal worm cultivated is not of the same race The zooplankter of class, algae removal speed is faster.
Meanwhile algae and algae removal worm are selected from the target water body administered in the technical program, can preferably adapt to water body, deposit Motility rate is higher.
Running water after being put into Air Exposure in container one and container two in the technical program, the purpose master of Air Exposure If removing chlorine-containing compound in running water, the influence to zooplankter, phytoplankton growth is avoided.
Preferably, the sampling method of target water body amount is in the step 3):Taken respectively on target water body using hydrophore Layer waters, midwater, each 10L in subjacent waters, mix and produce.
Preferably, the method that target water body amount 30L is concentrated into 50mL is to be concentrated using plankton net.
Preferably, the macrozooplankton and phytoplankton sociales that control algae is beneficial in the water body by 50ml are divided From the operation progress under microscope and anatomical lens.
Preferably, the separation of the phytoplankton is carried out using capillary, the selection species that biomass is big and density is big, i.e., Needed in target water body control the problem of algae.
Preferably, BG-11 culture mediums are added in the step 5) in container two and growth training is carried out to the advantage algae kind of separation Support, as the algae kind tamed to algae removal worm.
Preferably, algae in container two is dragged in container one daily in the step 5), injected volume is incremented by by 6%, continuously 5-8d, zooplankter is tamed, have certain tolerance to problem algae kind, the species finally left is algae removal worm.
Preferably, the step 7) dispenses algae removal worm, repeat the above steps carry out grow culture can obtain largely Algae removal worm, then goals of investment water body administered.
The present invention compared with prior art, has the following advantages and advantages:
(1) the algae removal worm that the technical program is turned out utilizes lower row effects, and algae can be carried out to herd food, reduces algae life Object amount, and algae removal worm is the live bait that fish are liked, is ingested by fish, is finally moved the nutritive salt in water in the form of fishery -ies product Water-outlet body, the nutrient concentration in water is reduced, is enhanced the transparency, to build the stable state of clear water aquatic system based on submerged plant Basic condition is provided.
(2) algae removal worm group is separated out using the moisture of target water body according to the theory of " original seed controls raw water " in the technical program Body and algae kind, then by inoculating and culturing out the algae removal worm come, it can be more easy to adapt to water body, survival rate is high, and algae removal speed faster, solves Algae removal worm does not adapt to water body in the prior art, and survival rate is low, except technical problems such as algae effect differences.
