There are many kinds of landscape water treatment technologies, mainly including physical, chemical and microbial treatment technologies. Physical techniques such as water exchange: the concentration of impurities in water can be diluted by means of water diversion and water exchange to reduce the concentration of impurities. However, a large amount of clean water needs to be replaced, which is bound to reduce the waste of precious water resources in today's scarce water resources. Chemical methods (adding the algae fungicidal) water in the sun, can make the algae blooms in the water, be full of the whole surface, not only affects the water body and beautiful, and blocked off the sun, leaving many underwater preventing plant photosynthesis, release oxygen, the chemical changes of the pollutants in water, causing water quality deterioration, giving off a terrible stench, water became black. So you put chemical fungicide in to kill the algae. Over time, there will be resistant algae in the water, and the efficiency of the algae suppressant gradually declines, the interval of drug administration will be shorter, and the amount of drug application will be more and more, the variety of algae suppressant will be changed frequently, and the pollution to the environment is also increasing, and this pollution will affect our next generation. However, at the same time, the chemical method equipment cost is high (circulating equipment, dosing device) and the operation cost is high (power consumption, pharmacy cost). Although the effect is obvious, it is short in maintenance time, easy to operate and requires special personnel management. Microbial treatment methods (ecological water treatment technology) a wide range of biological species, has a fairly complex physiological characteristics, in aquatic ecology, as the disintegrator of microbes, to the pollutants in the water (including organic matter, some heavy metals, etc.) to decomposition, absorption, become available to other living creatures can be material, at the same time it also can reduce or eliminate the toxicity of some toxic substances, can transform the residual heated of aquatic plants into organic fertilizer, increase soil organic matter, and improved the soil, improve soil granular structure and physical properties, improve the water environment capacity, enhance the capacity of self-purification of water body, It also reduces soil erosion and inhibits the growth of plant pathogenic bacteria.
Therefore, the application of water treatment agent progressives for water treatment is the most efficient and environmentally friendly. Growth provides favorable conditions, biochemical effects are formed, and the biochemical effects of microorganisms effectively remove organic and inorganic pollutants, providing favorable conditions for the next water treatment process.
