摘要
为研究改造优化后的新型转鼓式一体化装置+人工湿地组合工艺的处理效果,结合锦溪镇红霞村分散型农村生活污水处理示范工程,对新型组合工艺处理出水水质指标及其去除率进行了分析。结果表明,组合工艺可实现COD、NH3-N、TP、SS的总去除率最高达到90.20%、94.40%、91.82%、95.80%,出水COD、NH3-N、TP、SS浓度分别小于等于30.0、40.0、0.32、8.0 mg/L,水质长期稳定达到《城镇污水处理厂污染物排放标准》中一级A标准;组合工艺处理污水所需能耗仅接近常规能耗的50%。
To study the treatment effect of combined process about new drum-type integrated device and artificial wetland,taking the demonstration project of dispersed rural sewage treatment in Jinxi Hongxia Village for an example,the effluent quality index and removal rate obtained by the new combined process were analyzed.The results show that the combined process can realize the removal rate of COD,NH3-N,TP and SS,which are the highest up to 90.20%,94.40%,91.82%,95.80%.The effluent concentration of COD,NH3-N,TP and SS is less than or equal to 30mg/L,4.0mg/L,0.32mg/L,8.0mg/L.The quality can be long-term stability and it meets the first-level A criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant.Besides,the required energy consumption of the combined process is only close to 50% of the conventional energy consumption.
