Low Energy Consumption Wastewater Treatment Process under Coupling of Iron Carrier and Biology

为了降低污水处理工艺能耗,设计铁质载体与生物耦合下污水低能耗处理工艺。文章采集不同区域的污水作为研究样本,制备铁质载体与生物耦合反应器作为污水处理设备。测定初始输入污水水质,利用制备的耦合反应器实现污染物去除处理,计算并控制污水处理能耗,完成对污水的低能耗处理。经过测定污水处理结果,应用设计的处理工艺后总磷、总氮、汞离子污染物浓度分别减少约1.52 mg/L、4.68 mg/L、0.029 7 mg/L,能耗量控制在0.2 kWh/m^(3)以下。结论:提出工艺能够在保证处理效果的同时减少能源消耗量。

In order to reduce the energy consumption of sewage treatment process,the low energy consumption treatment process under the coupling of iron carrier and biological treatment is designed.In this paper,sewage from different areas was collected as research samples,and siderophore and biological coupling reactors were prepared as sewage treatment equipment.The study determines the initial input sewage water quality by using the prepared coupling reactor to realize the pollutant removal treatment.It calculates and controls the energy consumption of sewage treatment,and completes the low energy consumption treatment of sewage.After measuring the result of sewage treatment,the concentration of total phosphorus,total nitrogen and mercury ions were reduced by about 1.52 mg/L,4.68 mg/L,0.0297 mg/L after the application of the designed treatment process.The energy consumption is controlled below 0.2 kWh/m^(3).It is concluded that the process can reduce energy consumption.
