摘要：
Taking water system of limestone-gypsum Wet Flue Gas Desulfurization (WFGD) device as object of study. First, this paper carries on the analysis to the quality of desulfurization wastewater, then in view of the water quality characteristic of desulfurization wastewater the paper proposes the materialized treatment method, and conducts the experimental study. In the materialized method selecting polymeric aluminum ferric silicate sulfate (PAFSS) as the coagulant, then using the orthogonal experiments determine PAFS best text condition under remove of the sulfide, the fluoride and the COD by PAFSS: the pH value 8~9,PAFSS throwing content 20ml/l, PAM throwing content 10ml/l, coagulation mixing time 25min, settling time 20min. Under the best test condition the treatment effect: after coagulation processing, sulfide elimination rate 99.3%; fluoride elimination rate 96.5%;COD elimination rate 78.5%. And the results achieve requests of GB 8978-1998 integrated wastewater discharge standard.

摘要：
As an absorbent dark tea residue can get rid of heavy metal ion effectually and do no harm to the environment. From the dynamic experiment on dark tea residue's absorption of Cr(VI), the absorption dynamic curve and absorption isothermal curve are obtained. The effects of pH value, initial concentration, dosage of residue, adsorption time and other factors on absorption are studied and the result shows that: when the pH value of the waste water is 2, the initial concentration is 100mg/L, the adsorption time is 60min, the dosage of dark tea residue is 1g, the maximum adsorption rate reaches 99.96%.The adsorption conforms with the Langmuir adsorption isotherm, it is a kind of monolayer adsorption, the adsorption kinetics curve conforms with pseudo-second-order equation. In the end discusses the development prospect of dark tea residue.

摘要：
With increasing the degree of state environmental protection, the comprehensive treatment of waste water containing stibium has become a new subject in stibium industry.In this study,we modified diatomite with calcium carbonate,and adsorptived waste water containing stibium using these modified diatomite.Then we explored the quality of modified diatomite,initial concentration,initial pH value,temperature and adsorpting time on adsorption. The adsorption isotherm of stibium fits Langmuir equation.The result shows that the modified diatomite has good adsorption on waste water containing stibium.
摘要：
This paper Introduces a simple and reliable method to connect an ordinary twisted pair RS-232 up to 2048 devices and transmit the communication data more than 10 kilometers by using ZLGCAN interface card, CAN232MB converters and other equipment. The virtual serial port server makes use of CAN-bus network for data communications, guaranteeing the reliability of communic-ation, improving the RS-232 transmission distance, and simplifying the wiring process. Meanwhile user’s operation of the virtual serial port and a standard PC are compatible with the basic serial port operation. However, if there is a large number of continuous transmission of data to the case, the ac-tual serial data transfer rates is determined by the number of virtual serial port.

摘要：
I2S (Inter-IC Sound Bus) is one of the general audio buses applied in various industrial or embedded systems. It only processes the audio data, while other signals like various codes and control signals are transmitted individually. This paper presents an approach how to construct an embedded audio system using the I2S bus to connect relevant supporting code chip and decode chip. This system can reduce the consumption of system resources drastically, therefore fluent WAV broadcast can be guaranteed. Moreover, the familiar media files, such as MPEG1, MPEG2, MP3, MPEG4 can be played through adding its decoder. The ARM chipset of the LPC2300 series is applied in this system, therefore, system's reliability can be improved. This method can be wiedly used in vehicle- borne, ship-borne embedded flash players and portable media players.
