- Abstract:
- In view of the current situation of low influent concentration and overflow before sewage treatment plant as well as water quality problems caused by complicated terrain and underground pipe network system in Karst region, a comprehensive analysis of pipe system was carried out in Liupanshui, Guizhou Province to find out the main reason. After two years of systematic governance such as leading clean water into the river, separated sewer, and pipeline repair, the influent concentration was increased and the overflow was alleviated significantly, which could provide references for quality improvement and efficiency improvement of other urban sewage treatment system in Karst region.
