- Abstract:
- During the 13th Five-Year Plan period, Chinese cities have promoted the remediation of urban black and odorous water bodies, in accordance with the idea of “pollutant source control, internal source treatment, ecological restoration and flowing water quality assurance” and achieved remarkable achievements. However, pollutant source control of black and odorous water bodies in urban villages is restricted by multiple factors, such as land use conditions, construction sequence and management level, which has become a major problem in the treatment of urban water environment. High-density urban villages generally have the characteristics of undeveloped drainage infrastructure, limited shoreline land space, poor urban management and so on. Burying pipes along the shoreside and transporting wastewater to the treatment plant should be priority when feasible. Otherwise, other sewage collection and treatment methods should be selected according to local limited conditions. The combined modes of burying pipes, hanging pipes along the river, temporary hanging pipe, using integrated treatment facilities and regular pumping and transferring of septic tanks have been adopted to control the pollution to Lingjianxi River and Qingfenggou River in urban villages of Guilin, which can provide reference for treatment mode and technology selection for sewage collection and treatment in urban villages.
