- Title:
- Treatment Strategy of Black and Odorous Water in Karst Region of Liupanshui
- Keywords:
- Karst region; black and odorous water body; quality and efficiency improvement; clean and dirty water separation
- 摘要:
- 针对喀斯特地区复杂的地形地貌和地下管网系统导致的污水处理厂进水浓度偏低、厂前溢流、水体水质变差等问题，以贵州省六盘水市为例，通过管网诊断摸清底数，发现主要问题成因，采取引清入河、清污分流、管网修复等针对性措施，经过两年的系统治理，显著提高了污水厂进水浓度，缓解了厂前溢流问题，可为喀斯特地区其他城市的水体治理及污水处理提质增效工作提供借鉴。
- 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.
