The invention provides a hydrolytic agent for treating wastewater containing tetrafluoroborate and application thereof. The hydrolytic agent consists of at least one aluminum salt and at least one water-soluble cerate. The aluminum salt is selected from alum, aluminum chloride or hydrate of the aluminum chloride, aluminum sulfate or hydrate of the aluminum sulfate, and preferable the alum; and the water-soluble cerat is selected from cerium nitrate, cerous sulfate and cerium chloride, and the preferable the cerium chloride. The hydrolytic agent disclosed by the invention is used for treating the wastewater containing tetrafluoroborate, thus the consumption of the aluminum salt contained in the hydrolytic agent can be reduced on the one hand and the concentration of the tetrafluoroborate in the hydrated wastewater can be reduced on the other hand, which provide advantages for subsequent treatment. After the wastewater is continuously precipitated by lime milk or CaOH2, the concentration of the tetrafluoroborate and the concentration of fluorinion are respectively reduced and reach the discharge stand, and thus the etrafluoroborate and the fluorinion can be directly discharged and further the subsequent treatment flow is shortened.

The invention discloses a winnowing machine and a winnowing method thereof and belongs to the field of crop seed impurity removal machinery. The winnowing machine comprises a draught fan and an impurity collection box and further comprises a winnowing component, a feeding hopper and a discharging hopper, wherein the winnowing component is arranged below the feeding hopper; the discharging hopper is located below the winnowing component; the draught fan is located at the left side of the winnowing component; and the impurity collection box is located at the right side of the winnowing component. The winnowing machine further comprises flying dust adsorption equipment. The flying dust adsorption equipment comprises an upper air opening, a flying dust filter bag and a flying dust collection hopper in sequence from top to bottom. The impurity collection box comprises filter plates, a heavy impurity hopper, a light impurity hopper and a flying dust outlet. The winnowing component is arranged at the left side of the upper portion of the impurity collection box. The upper portion of the impurity collection box is formed by combining the filter plates. The heavy impurity hopper and the light impurity hopper are arranged on the lower portion of the impurity collection box in sequence from left to right. The flying dust outlet is formed in the right side of the upper portion of the impurity collection box. The flying dust outlet communicates with the flying dust adsorption equipment. By means of the winnowing machine, impurities in grains can be removed; mildewed or imperfect seeds are separated from good seeds which are plump in grain; and the seeds can be stored conveniently and sold and processed conveniently at the later stage.

A active code channel detection and configurator contains a active code channel detector and an active code channel configurator wherein the active code channel detector transmit information of received data and frequency channel response estimation information to active code channel configurator, the active code channel configurator makes judgment that whether start the active code channel configurator or utilize it to output code channel configuration information. Said invention can give out active code channel information configuration before demodulating code channel information.

The invention discloses a detection method and device for high-sensitivity and high-reproducibility surface enhanced Raman spectroscopy. The method that detection is performed repeatedly to obtain the average value is adopted, the problem of relatively high discreteness in the existing detection method is avoided, the method and the device have high reproducibility and ultrahigh analytical sensitivity, and are suitable for detection of ultratrace samples, detection results can be obtained accurately, the operation is simple, and the detection period is short. According to the method, a fine-tuning device is adopted, so that the movement of a substrate is achieved so as to perform multi-point detection, the device is simple in structure, lower in cost, and easy and convenient to operate; the method and the device provide conditions for further promoting the SERS technology to be widely used in the fields of homeland security, environmental monitoring, food safety, health care and the like.
