1. Physical method:
The propagation mode of Spirogyra is fracture propagation, that is, the filament breaks into several short silk due to mechanical injury or other reasons, and each short silk grows into a filament through cell division. That is, physical fishing will accelerate the growth and reproduction of Spirogyra, leading to more fishing.
2. Chemical methods:
At present, the commonly used chemical agents are mainly copper sulfate, permanganate, aluminum sulfate, ferrate complex, liquid chlorine, ClO2 _ 2, O3? And H2O2? Wait a minute. The use of chemicals is undoubtedly an effective way, with obvious and quick results, but it is only a palliative method and must be used with caution. First, chemicals themselves often have toxic and side effects, causing secondary pollution, which has a great impact on water organisms, and the river course after using chemicals is not conducive to biological recovery; Second, the use of chemicals can only control the spirogyra in water in a short time. Because it can't be completely killed, it will be revived soon, and sometimes it will even get worse, which will be a vicious circle for water. It can be said that using chemical methods to control rivers is "drinking poison to quench thirst". This country has restricted the use of chemical methods in river management.
3. Biological method:
Biological treatment principle of Spirogyra;
Use Eama- 1 1 Spirogyra biological algaecide to quickly inhibit the growth and reproduction of Spirogyra. It is domesticated and cultivated by microorganisms that have been screened from the natural environment and have inhibitory effects on the growth of Spirogyra. It is easily soluble in water, and can quickly spread to the surface of Spirogyra cells, and penetrate into the interior of cells to destroy the functional protein group of cells, so that the protein synthesis of cells is inhibited, the normal metabolism of cells is terminated, and finally the growth of Spirogyra is controlled.
Characteristics 1- Highly effective algae inhibition
It has strong ability to inhibit the growth of Spirogyra, and the biological agent has more than 90% inhibition effect on Spirogyra in water where Spirogyra has broken out.
Feature 2- Simple construction and site treatment
Bangyuan's environmentally-friendly biological river treatment process uses simple equipment and does not require a lot of manpower to salvage Spirogyra, that is, Spirogyra can be digested in water without turning out of the water. Therefore, the construction is convenient, the operation is simple, no noise is generated, and the normal life of the surrounding residents is not affected.
Feature 3-The product is green and pollution-free.
① Biological products are non-combustible, non-volatile, green, safe, non-toxic and free from secondary pollution.
② Good compatibility. Because the inhibitor has no toxic and side effects, it can be used in combination with other biological agents and has a synergistic effect.
③ Excellent biodegradability. After the inhibitor inhibits the growth of Spirogyra in water, there will be no residue.
4. Bio-ecological restoration technology
Eco-biological method is a new environmental biotechnology developed in recent years. This kind of technology mainly uses the life activities of microorganisms, plants and other organisms to transfer, transform and degrade pollutants in water, thus purifying water quality, creating an environment suitable for the survival and reproduction of various organisms, and rebuilding and restoring aquatic ecosystems. Because this technology has the advantages of good treatment effect, relatively low project cost, no or low energy consumption and low operating cost. At the same time, no chemicals are put into the water body, which will not cause secondary pollution. It can also be combined with greening environment and landscape improvement to create a beautiful environment in which man and nature are integrated. Therefore, it has become the main development direction of water pollution and eutrophication control.
Ecological biological restoration technology includes: micro-ecosystem restoration technology, constructed wetland technology, floating island technology, plant control technology, ecological revetment technology, ecological reoxygenation technology, ecological dredging technology, aquatic animal restoration and reconstruction technology, etc. In practical engineering application, different technical combinations can be selected according to the degree of water pollution, the present situation of water environment and the function of water body, thus showing a win-win situation of ecological benefits and economic benefits.
Beijing Bangyuan Environmental Protection Technology Co., Ltd. has completed dozens of water bioremediation projects in Beijing, Jiangsu, Shandong, Hainan, Hebei, Yunnan and other places by using biological methods and bio-ecological restoration technologies, and has rich management experience. Can provide the overall system solution, sunshine 24-hour tracking service mechanism.
Because the ultimate goal of inland river management is to restore the function and structure of river ecosystem and promote the self-maintenance and self-development of the system. Therefore, the bio-ecological restoration technology applied by Bangyuan Environmental Protection is considered to be the most valuable and vital bio-governance technology in the field of eco-environmental protection in China in 2 1 century.
