A wastewater treatment equipment and a treatment method of a wastewater are provided. The wastewater treatment equipment includes: a microfiltration unit, configured to receive and filter a wastewater to obtain a solution; a membrane salt separation unit, configured to receive the solution and separate monovalent ions and multivalent ions from the solution to obtain a first solution including the monovalent ions and a second solution including the multivalent ions; a first evaporative crystallization unit, configured to crystallize the first solution to form a monovalent salt; and a second evaporative crystallization unit, configured to crystallize the second solution to form a mixed salt; the microfiltration unit is connected to the membrane salt separation unit, and the first evaporative crystallization unit and the second evaporative crystallization unit are both directly connected to the membrane salt separation unit, the wastewater treatment equipment can achieve the standard discharge of wastewater.

Wastewater treatment equipment and treatment method thereof

Long-chain non-coding RNA NEAT1 are used in the preparation of drugs for the treatment of Fuchs' endothelial corneal dystrophy. Overexpression of the long-chain non-coding RNA NEAT1 can effectively reduce corneal endothelial damage, alleviate the symptoms of corneal edema, can be used for the treatment of Fuchs' endothelial corneal malnutrition.

Adeno-associated virus for activating RNA-NEAT1 over-expression and applications thereof

The present application is related to a method for identifying whether porcine heparin is adulterated with heparin from ruminants, comprising: (1) respectively detecting the contents of trisaccharide(4S) and &#x394;UA2S-GlcNAc6S (&#x394;IA) in a sample and at least three batches of porcine heparin standards; (2) calculating a ratio of the trisaccharide(4S) to the &#x394;IA as well as a standard deviation (SD) of the ratio in the porcine heparin standards; when the ratio of the trisaccharide(4S) to the &#x394;IA in the sample exceeds a maximum value of the ratio in the porcine heparin standards+3SD, where the sample is considered to be mixed or adulterated with heparin from ruminants; wherein the detection method used is hydrophilic interaction liquid chromatography-mass spectrometry (HILIC-MS) or multiple reaction monitoring (MRM). The method can distinguish porcine heparin from ovine and bovine heparin based on the structural differences, regardless of the production process the heparin has undergone.

Method for identifying whether porcine heparin is adulterated with heparin from ruminants

A self-crosslinkable polyurethane or polyurethane-urea aqueous dispersion, a preparation method therefor, and a use thereof. Side chains of the polyurethane or polyurethane-urea contain non-sterically-hindered siloxy groups. During the drying and activation of the aqueous dispersion, the siloxys in the side chains are hydrolyzed and crosslinked with each other to increase the cross-linking density, significantly improving the heat resistance, the humidity resistance, and other properties of an adhesive obtained therefrom. The aqueous dispersion itself has a good stability. In addition, an application system based thereon has an excellent stability and a long storage time. The aqueous dispersion is suitable for the preparation of high quality paints and sealants, especially adhesives.
