LTD Jintan city Jiangsu Province 213200 China

The MC-LR from the the blue-green algae of Taihu Lake was extracted, at the same time, a set of microcystins extraction method with methanol as extraction solvent and purification method with C18-SPE as purification workstations were established. The extraction solvent concentration, extraction time, extraction solvent amount, leacheate concentration and eluent concentration were used to research the extraction efficiency of MC-LR. Finally, 80% methanol was used to wash microcytins to make MC-LR high purity and the purity was over 85%. This research presented a method of low cost and high efficiency. It provided the foundation for the further research of microcytins.

2010 International Conference on E-Health Networking, Digital Ecosystems and Technologies

作者： Lifang Zhai,Cheng Huang College of Electronic Information Engineering,Jiangsu Teachers University of Technology changzhou city,Jiangsu Province,213001 China

The analog circuits course is an important elementary course in the electronic engineering specialty. The study mainly introduces the analog circuits course reform in the teachers college of technology, including the reform of theoretical teaching, practical teaching management, and examination of the experimental operations. Practice has proved that rational application of modern educational technology and the electronic design automation (EDA) software can effectively resolve the "difficult beginning" problem of the analog circuits course, and can closely integrate theoretical teaching with practical teaching. The study also introduces the implemental situations of the practical separation of teaching and testing.

2010 3rd International Conference on Future BioMedical Information Engineering (FBIE 2010)

作者： Zhang Wenyi a, Han Ningb, Yan Gang a, Xu Xia a and Chen Xiaoliangb a, School of Environmental and Safety Engineering changzhou University, changzhou city, Jiangsu Province, 213164, China b, Department of Equipment ManufactureJiangsu Hengliang Centrifuge Manufacturing Co., LTD , Jintan city, Jiangsu Province, 213200, China

Using NaCl modified zeolite with high specific surface area as filter media, algae-contained micropolluted water was treated with biological aerated filter (BAF) process. The removal efficiencies of the process on micro-pollutants and removal mechanism of algae-contained micropolluted water were investigated and studied. The results showed that better removal efficiency was obtained in turbidity, Chlorophyll-a, UV254, and CODMn when algae-contained micropolluted water was treated by BAF. The optimal process parameters of the treatment of algae-contained micropolluted water with BAF were gases/water ratio of 0.5.5, backwash cycle of 3 d, air/water backwash strength of 5 L/(m2·s), air backwash strength of 137 L/(m2·s), backwash time of 150min, temperature of 250℃, pH value of 7.8.5 and hydraulic load of 0.23.35 m3/(m2·h). The results of continuous running for 21 days showed that the removal efficiency of turbidity, Chlorophyll-a, UV254, and CODMn were up to 71.61%, 81.35%, 28.34% and 32.97% respectively under the conditions of these optimal parameters, and the effluent water could meet Grade II of the Drinking Water Quality Standards (CJ 3020～1993). This study could provide technical information for town water plant reconstruction of Taihu Lake and Chaohu Lake basin.
