Abstract: The invention provides a method for preparing drinking weak alkali water and strontium-rich electrolyte raw water from distilled water obtained in the process of producing salt from well and mine brine, which comprises procedures of pressure reduction treatment, primary filtration, membrane separation treatment, activated carbon adsorption treatment, secondary filtration treatment, sterilization and disinfection treatment and the like on the salt-making distilled water in sequence so as to remove insoluble solid impurities, sulfides, microorganisms and other substances in the raw water, and separate or enrich ions, thereby preparing the weak alkali water suitable for drinking and the strontium-rich electrolyte raw water capable of being used for functional beverage production. The method provided by the invention can not only realize the comprehensive utilization of resources, but also obtain new products, significantly improving the economical efficiency of the process.

Abstract: The present disclosure provides a lighting device for reducing bird strikes and a method for reducing bird strikes in a wind farm. The lighting device includes an illuminator, and the illuminator emits red light with a wavelength of 620-750 mm. In the present disclosure, the red light with a wavelength of 620-750 mm is used as a light source of the lighting device to reduce the attraction to birds; therefore, strikes of birds on the position of the lighting device can be reduced, overcoming a longstanding technical prejudice that people have generally accepted that blue light is used as a light source for reducing bird strikes because the red light is easy to attract birds, which are too sensitive to the blue light to be attracted easily.

Abstract: The invention provides a method for preparing strontium-rich mineral water from distilled water obtained in the salt production process from brine, which comprises the following steps: carrying out aeration pretreatment on the salt-making distilled water to obtain pretreated distilled water, and further performing sand filtration, ion exchange, activated carbon, membrane filtration and sterilization and disinfection treatment on the pretreated distilled water to obtain the drinking strontium-rich mineral water with the strontium element content of more than 0.4 mg/L.

Abstract: The present invention provides table salts. The said table salts contains 50 to 600 mg/kg of strontium. The strontium-rich table salts provided by the present invention has significantly higher strontium content than traditional common table salts. As one of the essential trace elements, strontium plays an important role in human health. The said table salts provided by the present invention are rich in strontium, which can be assimilated by human body during taking the said table salts. Moreover, the strontium content in the table salts provided by the present invention ranges from 50 to 600 mg/kg, which enables human body to get enough strontium to meet human needs when taking normal amount of the said table salts daily.

Abstract: Disclosed is a process for preparing biodiesel from renewable oil and fat catalyzed by lipase with online dehydration. The method uses a short chain alcohol ROH as an acyl-acceptor, and utilizes a lipase as the catalyst to catalyze transesterification reaction of oil and fat feedstock with said short chain alcohol, so as to synthesize biodiesel; and online dehydration with a membrane or a molecular sieve is carried out during the whole process or part of the reaction process. Such online dehydration process greatly simplifies the operation procedure, and provides good economic and environmental benefits.
