摘要
[目的]为养猪场废水的达标处理工艺研究提供参考和借鉴。[方法]将供试废水加到水生植物处理装置中,再加入处理稀释养猪场废水后的健康浮萍及水花生,于人工气候培养箱内连续培养1周,监测COD、NH4+-N、TP和pH值的变化。[结果]结果表明,试验期间废水COD、NH4+-N和TP浓度均持续降低,总去除率分别为75.7%、47.6%和83.0%,最终出水浓度分别为336.51、95.2和7.2 mg/L,处理系统运行良好。[结论]利用浮萍混养体系处理养猪场废水具有较好的经济可行性及广阔的应用前景。
[Objective] The aim of the research was to provide references for the standard treatment study of swine wastewater.[Method] The experimental swine wastewater was added into aquatic plants treatment system,and then healthy duckweed as well as alligator weed were added into this system.During the breeding period for one week in artificial climate incubator,chemical oxygen demand（COD）, ammonia nitrogen（NH4＋-N）,total phosphorus（TP） concentrations and pH value were monitored.[Result] The results showed that,concertrations of COD,NH4＋-N, and TP of the tested wastewater all decreased during the trial period,with the total removal rates and concertrations of the final effluents 75.7%,47.6%,83.0% and 336.5,195.2,7.2 mg/L,respectively.The treating system operated well in the trial period.[Conclusion] The application of duckweed-cultured system in swine wastewater treatment processed very good feasibility and prospect.
