- Abstract:
- At present, many municipal wastewater treatment systems in China are still facing the problem of low efficiency in collection and treatment process. How to improve the quality and efficiency of sewage system has become a research focus. Based on the case study of typical hilly cities in the Yangtze River basin, the root causes and solutions of low efficiency of drainage system are discussed. It is pointed out that the point of extraneous inflow should be accurately identified and its infiltration should be quantitatively evaluated on the basis of thoroughly systematical investigation. Then appropriate strategies should be made according to the features of the problem and conditions of road network reconstruction. Therefore, with water-sewage diversion as a breakthrough, the urgent and orderly reconstruction plan should be conducted in the sequence of focus first and then overall, which can provide guidance and reference for improving quality and efficiency of sewage system in hilly cities.
