Abstract

The invention relates to a culture method of an aquatic plant in low-concentration phosphorous enriched slightly-polluted water, and belongs to the field of sewage treatment. The method comprises the following steps: culturing a batch of water lettuces in a pollution-free pond; removing the outside leaves until 3 to 4 leaves are remained; sterilizing; transferring into a 5L glass tank in which deionized water is contained; irradiating with a 40w fluorescent lamp under room temperature; adding sodium dihydrogen phosphate, agar, glucose, sodium chloride and magnesium sulfate to the deionized water in the glass tank; removing any new leaves of the water lettuces; transferring into another 5L glass tank in which the deionized water is contained; irradiating with the 40w fluorescent lamp under room temperature; transferring into the previous glass tank after irradiating for a certain time; respectively adding certain number of sodium dihydrogen phosphate, agar, glucose, sodium chloride and magnesium sulfate; culturing for 30 days to obtain phosphorous-enriched concentration factors of the water lettuces. According to the culture method, the sewage can be purified, and eutrophication of water mass can be treated.

Description

technical field [0001] The invention relates to a method for cultivating low-concentration phosphorus aquatic plants enriched in slightly polluted water, belonging to the field of sewage treatment. Background technique [0002] The main sources of phosphorus in water bodies are chemical fertilizers, human and animal manure, soil erosion and phosphorus-containing detergents. In urban domestic sewage, phosphorus in phosphorus-containing detergents is the main source of phosphorus in water bodies. Studies have shown that 80% of the phosphorus in lakes and reservoirs comes from sewage discharge, and the main source of phosphorus is the use of household detergents, whose phosphorus pollution intensity accounts for about 50% of the total phosphorus pollution load. Since the 1960s, as the world's densely populated large lakes have been polluted by organic matter such as nitrogen and phosphorus, it has attracted the attention of many developed countries and regions, and a worldwide...
