中小型城市生活污水处理研究

针对全国中小城市污水处理率低，水质变化范围大的特点，开发出了满足经济欠发达地区需求、高效的污水处理双膜H／O工艺，该工艺的中试装置已经应用于处理嘉应学院生活小区污水达一年时间以上，该新型工艺较活性污泥法容积负荷高，污泥产生量少，脱氮功能强，处理出水水质符合国家Ⅰ级排放标准．

The Research of Medium-sized City and Town Sewage Disposal

At present,the rate of China's medium-sized city and town sewage disposal is very low,and it is required that they establish their waste water treatment plants to deal with sewage that varies in a great range in several years.It is a tough task for them because most of them can't afford a highly cost traditional municipal waste water treatment plant.Now,the bimembrane H/O technology has been developed to meet the demand,particularly as far as the underdeveloped is concerned.The prototype devices have been used to dispose Jiaying college's sewage for more than one year.The experiment shows that the new technology has higher sludge volume load,produces less sludge,and do better in denitrification than traditional activated sludge technology.The experimental datas prove the quality of treated water coincides with the first grade of the national discharging standards of water.
