There are more than 20 kinds. The Chinese mainly comprises Chinese soft-shelled turtle, wattle-necked soft-shelled turtle, pelodiscus sinensis and soft-shelled turtle, wherein the Chinese soft-shelled turtle is the most common. The soft-shelled turtle is not only a delicious food on a dining table, but also a high-quality material of a high-class sheet, and can be used as a traditional Chinese medicine material for medicine. It has tonic, heat clearing away, yin nourishing, liver calming, wind calming, hard mass softening, stagnation eliminating, liver cirrhosis, hepatosplenomegaly, infantile convulsion, etc. During the turtle breeding process, a large amount of breeding wastewater is generated, elements such as nitrogen and phosphorus in the wastewater seriously exceed the standard, and high-concentration organic polluted breeding wastewater is formed.
