- Abstract:
- To optimize the existing payment mode for sewage treatment enterprises and alleviate the financial burden on the government, a performance-based payment model and method were developed for sewage treatment plants in Wuhan. This was based on the operating costs and water quality indices of 10 sewage treatment plants in Wuhan, Hubei Province, focusing on influent quality, treatment volume, and pollution load reduction. Subsequently, the accuracy and practicality of the three payment methods were thoroughly examined. Model equations could be developed for power cost and ammonia nitrogen reduction, raw material acquisition cost and total phosphorus reduction, as well as sludge disposal cost and total phosphorus concentration of influent. By comparing the actual cost with the model results, it was found that the estimated power cost closely aligned with the actual expenditure. The comprehensive pay for performance model was applicable to the cost pricing of sewage treatment plants with lower influent biochemical oxygen demand (BOD5). Studying the performance payment theory of sewage treatment, based on the “one plant one policy” model and integrated with the performance appraisal system of sewage treatment, holds great significance and practical value.
