Embodiment
[0050] see figure 1 , a kind of water restoration method based on freshwater pearl cultivation, the method comprises the following steps:
[0051] Step 1: Perform simple physical pretreatment on the water body to be repaired, and remove floating objects and larger suspended particles on the surface of the water body by manual salvage;
[0052] Step 2: Physically clean the bottom silt of the water body, and perform deep aeration at the bottom of the water body to increase the oxygen content and transparency of the water body;
[0053] Step 3: Place suspended restoration platforms evenly in the water body, with an interval of 150m between two adjacent suspended restoration platforms, and plant a large aquatic plant that has been screened between two adjacent suspended restoration platforms;
[0054] The screening method for large aquatic plants is as follows: collect a sufficient amount of water from the water body that needs to be repaired, place multiple large aquatic plants ...

The invention discloses a remediation method for a water body on the basis of freshwater pearl culture, and belongs to the technical field of remediation of the water body. The remediation method forthe water body on the basis of freshwater pearl culture comprises the following steps: step 1, subjecting a to-be-remedied water body to simple physical pretreatment, and removing floating matters andlarge suspended particulate matters on the surface of the water body in a manner of manual salvaging; and step 2, subjecting sludge located at the bottom layer of the water body to physical cleaning,and carrying out deep aeration at the bottom part of the water body. According to the invention, by combination of a biological remediation method and a chemical remediation method on the basis of basic water body remediation measures, and through cooperative application of a suspending remediation platform, comprehensive remediation of the water body is realized, and no new pollution element canbe brought to the water body at the same time; and compared with a conventional remediation method for the water body, the remediation method provided by the invention can improve the water quality of the water body with multiple means under the condition that no new pollution element is brought in, so the remediation effect on the water body can be significantly improved.
Description
technical field [0001] The invention relates to the technical field of water restoration, in particular to a water restoration method based on freshwater pearl cultivation. Background technique [0002] my country is a country with a long history of pearl mining, and it is also the country with the longest history of artificial cultured pearls in human history. Pearl culture can be divided into seawater pearls and freshwater pearls in terms of water areas. The types of seawater pearl culture are: Hepu pearl oyster, large pearl oyster Mother oyster, black butterfly oyster, penguin mother-of-pearl, etc. The types of freshwater pearl cultivation include: triangular sail mussel, pleated crown mussel, anodonta dorsalis and kangle mussel, etc. Among them, the marine culture species is mainly Hepu pearl oyster shellfish, while the freshwater pearl cultured species is mainly triangular sail clam. [0003] For freshwater pearl cultivation, you should choose a water area with guarantee...
