摘要
研究对改良型多级厌氧/好氧-膜生物反应器工艺进行了参数优化,以提高污水处理效率和膜组件寿命。研究调整了进水流量和流量分配比,并在好氧区添加了挂膜填料以增强硝化反硝化。研究结果显示,添加填料的系统在6 h水力停留时间下化学需氧量去除率提高至90.60%,出水浓度为23.18 mg/L,优于无填料系统的86.20%。在氨氮去除上,填料系统达到98.55%的效率,出水浓度为0.64 mg/L,而无填料系统在8 h和6 h水力停留时间下的效率分别为98.26%和96.46%,出水浓度较高。研究成果可为污水处理技术的发展提供科学依据。
The study optimized parameters of the improved multi-stage anaerobic/aerobic-membrane bioreactor process to improve sewage treatment efficiency and membrane module life.The study adjusted the inlet water flow and flow distribution ratio,and added film fillers in the aerobic zone to enhance nitrification and denitrification.Research results show that the chemical oxygen demand removal rate of the system with added fillers increased to 90.60%under 6 hours of hydraulic retention time,and the effluent concentration was 23.18 mg/L,which was better than the 86.20%of the system without fillers.In terms of ammonia nitrogen removal,the packing system achieved an efficiency of 98.55%,and the effluent concentration was 0.64 mg/L,while the efficiency of the packing-free system at 8 hours and 6 hours hydraulic retention time was 98.26%and 96.46%respectively,and the effluent concentration was higher.The research results can provide scientific basis for the development of sewage treatment technology.
