Description
Technical field
The method that the present invention relates to microbial treatment algae-containing water body, is specifically related to one and utilizes mineral matter algae to decompose promotion
The method of agent assisted recombination microbial treatment algae-containing water body.
Background technology
Blue-green algae is prokaryotes, cries again blue-green alge, has colloid clothing outside the cell membrane of most of blue-green algaes, and blue-green algae is the simplest
Single, the most original one.In the water body that some are nutritious, blue-green algae is often in amount reproduction in summer, and forms one layer at the water surface
Blue-green and have the offscum of bad smell, referred to as wawter bloom.Wawter bloom can cause water quality deterioration, exhausts water oxygen gas and cause fish time serious
The death of class.In blue-green algae, some kind (such as Microcystis aeruginosa) also can produce Microcystin, and Microcystin can be directly to fish, people
Livestock products are raw to be poisoned.
Water bodies of rivers and lakes algae administer be a global problem, in recent years the administering method of blue-green algae mainly have chemical algae removing,
Machinery is fished for and microbial method.Compared with fishing for chemical algae removing and machinery, microorganism can be by microorganism except the advantage of algae
Degraded, absorption and transformation the nutriment in water body is removed from water body, it is not necessary to put into substantial amounts of manpower and materials
Just the polluter in water body can be removed.
It is a kind of both economical, quick, administering method of non-secondary pollution that microbial technique administers algae, at algae-containing water body
Improvement plays an important role in field.Complex microorganism is mainly by producing resistant activity material suppression harmful bacteria and harmful algae
Growth and breeding, and there is stronger protease, lipase, diastatic activity, that can decompose in algae and water is organic
Pollutant.Application result shows, compound microorganisms has obvious reduction effect to the content of water body chlorophyll, can be effective
The growth of suppression algae.But using merely the weak point of microbial treatment algae is to take effect slowly, the elimination of algae and degraded
Need the longer time, it usually needs twice of thoughtful one month.

The landscape impoundments application of Fengtai, embodiment 2 Beijing
The method of the investigation present invention algae regulation effect to Fengtai District, Beijing City landscape impoundments.The feature in this lake is
Moisturizing water source is recycled water, and rate of water make-up meets evaporated seepage water amount, does not has ecology to change the water water yield, enters lake without sewage mouth source, administers
Mode is annual improvement continuously.
Addition method is as follows: be fixed on the power speedboat not less than 10, compounding bin, Insecticide sprayer at volume 0.5m3
PE make up a prescription and add clear water 400L in cylinder, weigh mineral matter algae distintegrant 2.5kg, complex microorganism bacterial classification 5kg, stir.
Then by 5.5 horsepowers of high pressure Insecticide sprayers (lift 22 meters), the water surface is entered by confection with 40 degree of angles (pencil and water surface angle)
Row sprays, the shower nozzle distance water surface 0.5～0.6 meter, speedboat travel speed 12～15 kilometers/hour.
Improvement initial stage (first week) adding of agent frequency is once a day, administers mid-term (second week～4th week) medicament and throws
Add frequency be every 2 days once, administer later stage adding of agent frequency be weekly.When there is river course flood or having sewage to enter
Determine according to actual conditions and add frequency.Its mineral algae decomposition accelerating agent is only the initial stage of improvement (first 2 weeks) and generation spy
Add during different situation.
Algae distintegrant and complex microorganism need after adding water body, with speedboat, the water body after dispensing is carried out No. 2～3 machines
Tool impacts, and to accelerate the medicament decomposition rate to algae, reduces the reaction time further.
Started to carry out this lake ecological management from 2011, the annual dosage of complex microorganism bacterial classification 2011 is 2.5g/m3,
Mineral matter algae distintegrant dosage is 1.0g/m3.2012～2014 annual dosages are 1.5g/m3, mineral matter algae distintegrant
Dosage is 0.5g/m3.Simultaneously in this lake governance process, water quality sampled and detected, monitoring index have pH, COD,
7 indexs such as BOD, TP, ammonia nitrogen, transparency, chlorophyll a, monitoring concrete condition is as follows:
Table 1 Fengtai District landscape impoundments water monitoring data table
From detecting data it can be seen that the chlorophyll content lake is greatly lowered after Zhi Liing, organic contamination substrate concentration
Also significantly decreasing, water quality maintains essentially in surface water IV class water standard.
River course, embodiment 3 Beijing algae administers application
This experimental section total length about 4.2 kilometers, water surface area about 8.4 ten thousand square meter.The feature in this river course is: upstream has continuously
Water, and have a small amount of sewage mouth to import, administration way is annual July～November.Use addition method described in embodiment 2,
The complex microorganism bacterial classification dosage in 2013 years and 2014 years is 3.0g/m3, mineral matter algae distintegrant dosage is equal
For 1.5g/m3.Before administering, water quality algal grown is serious, and after the improvement in four weeks, water body eutrophication degree is significantly
Reduce.
Table 2 2014 annual Beijing river water quality Monitoring Data table
From detecting data it can be seen that the chlorophyll content lake is greatly lowered after Zhi Liing, organic contamination substrate concentration
Also significantly decreasing, water quality maintains essentially in surface water IV class water standard.
River course, comparative example 1 Beijing algae administers application
Experiment section is river course described in embodiment 3, and administering method is individually to add the complex microorganism used by embodiment 3,
Using addition method described in embodiment 2, dosage is 3.0g/m3.Improvement result is as shown in table 3.
Table 3 2013 annual Beijing river water quality Monitoring Data table
Compare with the result of embodiment 3 it can be seen that water quality was controlled with 2014 before this experimental section improvement of 2013 years
Overall before reason quite its Determination of Chlorophyll and ammonia-nitrogen content are more slightly higher than 2014, from Monitoring Data table 3 it can be seen that former at water body
In the case of beginning water quality is substantially suitable, individually adds " complex microorganism bacterial classification " and be added without " natural mineral matter extract ", algae
Class decomposition rate adds the decomposition rate of " natural mineral matter extract " under conditions of being significantly lower than, water quality is obviously improved the time and is
5 weeks, the time reaching water stabilization was 7 weeks.Under conditions of within 2014, auxiliary has added " natural mineral matter extract ", water body water
It is 3 weeks that matter is obviously improved the time, and the time reaching water stabilization is 4 weeks.Therefore auxiliary adds " natural mineral matter extract "
Speedup effect is obvious.
