Description
Technical Field
The invention belongs to the technical field of environmental protection, and particularly relates to a water body algae inhibiting method.
Background
The problem of water resource shortage is increasingly aggravated worldwide, the regenerated water becomes an important source for water source supply of landscape water bodies in water-deficient cities, but the regenerated water still contains nutrient substances such as nitrogen and phosphorus with higher concentration, and the landscape environment utilization process has the risks of receiving water body eutrophication and algal bloom outbreak. Aiming at the bottleneck problem that the outbreak growth of algae in the reclaimed water is difficult to be effectively controlled by the traditional method, ultraviolet algae inhibition is gradually paid attention. However, the algae inhibiting effect of ultraviolet rays is in a positive correlation trend with the dosage, the algae starts to grow again after a period of time, and a longer inhibition period requires a higher ultraviolet dosage. In view of the limited space and load capacity of the algae control apparatus, there is a limitation in merely increasing the number of ultraviolet lamps.
Therefore, the invention is especially provided.
Disclosure of Invention
In order to solve the problems that the space and the load capacity of an algae prevention and control device are limited, the mode of only increasing the number of ultraviolet lamps is limited, and the like, the invention provides a water body algae inhibiting method combining ultraviolet rays and allelochemicals, which strengthens the algae inhibiting effect and reduces the treatment cost by combining the ultraviolet rays and the allelochemicals.
The invention provides a water body algae inhibiting method which is sequentially carried out according to the following steps:
(1) carrying out ultraviolet irradiation on the water body;
(2) adding allelochemicals into the water body.
Preferably, the wavelength of the ultraviolet light used for ultraviolet irradiation in step (1) is in the C-band.
Preferably, the wavelength of the ultraviolet light is 254 nm.
Preferably, the ultraviolet dose used for ultraviolet irradiation in the step (1) is 20-2000mJ/cm2。
Preferably, the allelochemicals added in step (2) are one or more of phenolic acid, alkaloid, fatty acid and lipid.
It should be noted that, for allelochemicals with low solubility, the allelochemicals can be added into the water body by preparing the allelochemicals into stock solution by using a cosolvent and then adding the stock solution.
Preferably, the allelochemicals are alkaloids, more preferably berberine.
Preferably, the addition amount of the allelochemicals added in step (2) is 0.2-10 mg/L.
The principle of the invention is as follows: the difference of the attack positions of ultraviolet rays and allelochemicals on algae cells is utilized; the ultraviolet rays can immediately damage DNA of the algae cells, reduce the photosynthetic activity and improve the intracellular oxidation pressure of the algae cells; the allelochemicals obviously damage the photosynthetic system of the algae cells, influence the membrane potential of the algae cells and improve the apoptosis level. The ultraviolet rays and allelochemicals are combined to cover double ways of attacking ultraviolet injury positions (playing a role in strengthening injury) and attacking non-ultraviolet injury positions (playing a role in synergy injury), and the synergy injury is generated on an electron transfer chain of the photosynthetic system I I, so that the energy metabolism interference and intracellular oxidation pressure of algae cells are aggravated, the programmed death process of the algae cells is strengthened, the injury level of cell membranes of the algae cells is improved, and the algae inhibiting effect is strengthened.
The positive progress effects of the invention are as follows:
compared with the prior art, the water body algae inhibiting method provided by the invention can effectively inhibit the growth of algae in the water body, obtain an inhibition period of more than 2-3 weeks, generate a faster algae cell lethal effect, effectively control the content of microcystic toxins, interfere the intracellular synthesis process of the microcystic toxins, obviously reduce the dosage of ultraviolet rays and allelochemicals, is beneficial to the application of a device for preventing and controlling the algae in the landscape water body in practice, and effectively prevent and control the water bloom outbreak of the landscape water body.

The results of the above examples and comparative examples show that the treatment of algae by using the combination of UV light and allelochemicals as described in the present invention can effectively inhibit the photosynthesis and growth of algae, and the treatment effect is much better than that of the UV light treatment alone or the allelochemicals addition treatment. Meanwhile, the sequence of adding the allelochemicals and ultraviolet irradiation has certain influence on the final treatment effect. Firstly adding allelochemicals and then carrying out ultraviolet irradiation, on one hand, the ultraviolet rays can oxidize the allelochemicals and reduce the effect, and on the other hand, the allelochemicals can influence the penetration rate of the ultraviolet rays, thereby seriously influencing the synergistic effect of the two modes.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
