Research on the current situation and development of sewage collection and treatment facilities in towns of Beijing-Tianjin-Hebei
The 14th Five-Year Plan for the development of urban sewage treatment and re-source utilization has set higher requirements for the sewage treatment levels of towns in the Bei-jing-Tianjin-Hebei region.The study found significant differences and imbalances in sewage treat-ment levels among these towns.Towns in Beijing and Tianjin,with their relatively developed econ-omies and higher urban density,have almost complete coverage of sewage treatment facilities.However,sewage treatment efficacy still needs improvement,with treatment rates at 69.57％and 78.81％,respectively.In contrast,towns in Hebei province face challenges due to large built-up areas,complex landforms,and scattered town areas.The proportion of towns treating sewage in Hebei is only 65.28％,far below the national average.There are still many gaps in the construc-tion of sewage treatment facilities,with per capita investments of only 44.2 and 31.7 yuan/person,indicating a lack of financial support for the regular operation of sewage treatment.Therefore,it is crucial to strengthen research on the current state of sewage collection and treatment in the Beijing-Tianjin-Hebei towns.Proposing optimization suggestions in terms of sewage treatment modes,sci-entifically setting standards,establishing a sewage pricing mechanism,and improving design plan-ning is vital for the sustainable development of sewage treatment in this region.
