  给排水资料库   谁要英文电子书（本专业和非本专业的）？？？

  很久不来这里了，也不常来了。手头有给水排水专业的英文电子书《Engineering and Design—DESIGN OF SMALL WATER SYSTEMS》，不知有需要的没有，是PDF格式的，还有不少不是本专业的英文电子书哦。有需要的请留下信箱地址，如果版主同意我可以上传到网站（现在都不知道怎么上传文件了，请版主示下）。

  tic wastewater in a five-step sequencing batch reactor (SBR) was investigated at different hydraulic residence times (HRTs). The nutrient removal process consisted of anaerobic (An), anoxic (Ax), oxic (Ox), anoxic (Ax), oxic (Ox), and setting phases. The sludge age (SRT) was kept constant at 10 days, while the HRT of each phase was varied. Effects of hydraulic residence time of each phase on COD, nitrogen (NH4-N) and phosphate (PO4-P) removal were investigated. The hydraulic residence time of each phase was varied at four different levels and the most suitable residence time, resulting in maximum overall nutrient removal was determined. The highest observed COD,nitrogen (NH4-N) and phosphate (PO4-P) removal efficiencies were 96,87 and 90%, respectively, which was obtained with An/Ax/Ox/Ax/Ox phase residence times of 2/1/4.5/1.5//1.5h.
