Method for restraining formation and growth of spirogyra on water surfaces

Abstract

The invention provides a method for restraining the formation and growth of spirogyra on water surfaces. The method is characterized by comprising the following steps: when the daylight intensity is 2500-5000 lux, and water temperature is 7-25 DEG C, chlorine dioxide with the concentration of 2.3-4.5 mg / L is splashed or put on the water surfaces of water bodies of ponds, ditches, or lakes, in which a large amount of spirogyra grows, for 2-3 times with the time interval of 5 minutes, so as to enable the chlorine dioxide to be in full contact with the spirogyra on the water surfaces for 10-15 minutes, the structure of the spirogyra is damaged, and finally, the spirogyra degrades automatically until disappearing. Therefore, the purposes of restraining the formation and growth of spirogyra on the water surfaces are achieved, and that a large amount of spirogyra breeds is controlled. The method provided by the invention is suitable for restraining the formation and growth of spirogyra on the water surfaces of water bodies of the ponds, the ditches, or the lakes, and controlling the condition that a large amount of spirogyra breeds.

Description

technical field [0001] The invention relates to a water body environment protection technology, in particular to a method for inhibiting the formation and growth of Spirogyra on the water surface. Background technique [0002] How to effectively control the outbreak of Spirogyra has been paid more and more attention by people. Spirogyra is a eukaryotic multicellular algae living in fresh water. The algae body is an unbranched filament formed by a column of cylindrical cells. There are more pectin on the surface of the algae body. It feels sticky and slippery to the touch. Under the microscope, it can be seen that there are one or more band-shaped leaf margins in each cell, spirally wound in the cytoplasm close to the inner side of the cell wall, there is a column of protein nuclei on the chloroplast, and there is a large vacuole in the center of the cell. One nucleus is located in a group of cytoplasm in the center of the vacuole, and there are many radial cytoplasmic fila...

Problems solved by technology

[0003] At present, algae removal methods mainly use physical methods such as artificial algae fishing, flocculation, and filtration, adding chemical agents such as copper sulfate and isothiazolinones, adding chemical methods such as ozone and iodophor, and physical and chemical combination methods, and adding photosynthetic bacteria for biological treatment. Such methods, although they can all achieve a certain treatment effect, have a large workload, high economic costs, serious secondary pollution, poor control of Spirogyra outbreak, and affect water quality. Chlorine algae killing will lead to a large number of harmful by-products halogenated Hydrocarbon generation. When sodium hypochlorite is used as algicide, the dosage concentration is high and the reaction time is long. At the same time, sodium hypochlorite will cause serious damage to other aquatic animals, aquatic plants and beneficial microorganisms in the water body, destroying the structure and function of the water ecosystem. On the contrary, secondary pollution will be generated, causing water quality to deteriorate, and at the same time, the odor will be serious, affecting people's physical and mental health.
