摘要
为摸清长江经济带污水处理现状,助力长江经济带城市水环境保护,采用座谈、资料收集和现场走访的方式,调查了长江经济带7个重点省区城镇600座污水处理水厂的运行规模、处理工艺、运营模式,分析了污水处理领域主要竞争主体和市场空间。结果表明:长江经济带7个重点省区污水处理率达到97.69%,与全国平均水平基本持平,但污水处理厂进水污染物浓度普遍低于全国平均值;污水处理工艺以A2/O和氧化沟工艺为主,运营模式主要为BOT和托管运营,占比约50%;污水处理市场空间仍较大,污水管网的建设和修复将引领新的投资热点。研究成果可为长江经济带城镇污水处理投资和决策提供基础数据支撑。
In order to understand the current situation of sewage treatment in the Yangtze River Economic Belt,the operating scale,treatment processes,and operation models of 600 sewage treatment water plants in 7 key provinces and regions of the Yangtze River Economic Belt were investigated by conducting discussions,data collection,and on-site visits.The results showed that the sewage treatment rate in the Yangtze River Economic Belt had reached 97.69%,which was basically consistent with the national average level.However,the concentration of pollutants in the inflow of wastewater treatment plants was generally lower than the national average.The wastewater treatment process was mainly based on A2/O and oxidation ditch processes.Build-operate-transfer(BOT)and custody operation were the mainly operating modes of wastewater treatment plants in the Yangtze River Economic Belt,which accounted for about 50%.In terms of the market space,the construction and repair of sewage pipe networks will lead the investment direction in the construction of urban sewage treatment facilities in the Yangtze River Economic Belt.The research results can provide support for investment and decision-making in urban sewage treatment in the Yangtze River Economic Belt.
