Abstract: The present disclosure discloses a contact angle measuring device, including a light source, a container, a photodetector, a bubble generating unit, and a processing unit. The container includes a first and a second side walls that are opposite. The first side wall is made of a light-transmitting material, the container is filled with a liquid with light transmission inside. The monochromatic light emitted by the light source passes through the first side wall and enters an interface between the first side wall and the liquid. The bubble generating unit is configured for generating a bubble that is in contact with an inner surface of the first side wall. The photodetector is configured for detecting light intensity distribution of the monochromatic light through the liquid.

Abstract: The present invention provides a method for treating dye wastewater. The method includes: firstly, homogenizing the dye wastewater to balance the quality of the dye wastewater from different processes; then subjecting the homogenized dye wastewater to anaerobic treatment to remove most of chemical oxygen demand (COD) and total suspended solids (SS) in the wastewater; and finally subjecting the dye wastewater after the anaerobic treatment to circulating anaerobic-oxic treatment in a membrane bioreactor (MBR). In the present invention, the MBR is filled with a quinone-based hollow fiber membrane. The quinone acts as an electron mediator to accelerate an enzymatic reaction for dye decolorization during the anaerobic process, thereby achieving the purpose of efficient decolorization. The oxic treatment process further removes the COD and SS in the wastewater, so that the effluent meets a first-level discharge standard. The results of the examples show that by treating the dye wastewater by the method provided by the present invention, the COD in the effluent is less than 100 mg/L, the chromaticity is less than 20 times, and the SS is 0.

Abstract: Disclosed is a method of fast identifying the distribution rule of wind speed, for identifying an optimal distribution rule of known wind speeds, wherein transforming all types of distribution rules to be selected by Rosenblatt transformation to a uniform type based on the selected distribution type of the probability paper, and drawing the reference curve on the probability paper; selecting a plurality of distribution rules, selecting the known wind speed data as the sample data and comparing the point set of the sample data to the reference curve; judging the optimal distribution rule among the selected distribution rules according to the comparison result. The present invention is appropriate for identifying the distribution of wind speed of different range; the method is not specific to any probability paper that has wide applicability. The method is fast and highly efficient and it can achieve comparison of multiple distributions of the wind speed samples at the same time, the distribution types are not limited, the fitting results are visualized. The present invention can quantitatively analyze the degree of fitting of the multi-distribution samples without tedious calculations, thereby scientifically selecting the superior distribution rule of the wind speed samples.

Abstract: A method for treating domestic sewage includes: preliminarily treating the domestic sewage through a grating and a grit chamber, so as to remove large-particle solids in the domestic sewage; and subjecting the domestic sewage after the preliminary treatment to circulating anaerobic-oxic treatment in a membrane bioreactor (MBR). In the oxic treatment process, microorganisms oxidize nitrogen in the sewage into nitrite or nitrate. Under anaerobic conditions, denitrifying bacteria in the microorganisms reduce the nitrate, releasing molecular nitrogen or nitrous oxide. In the present invention, the MBR is filled with a quinone-based hollow fiber membrane. During the microbial denitrification, the quinone acts as an electron transfer carrier to participate in the denitrification to promote the reduction of the nitrate (nitrite), increasing the denitrification rate under anaerobic conditions, and achieving the purpose of efficient denitrification.
