为推进包埋微生物载体技术在污水处理领域的工程应用，针对包埋载体在工程应用中出现的出水易堵塞问题，开发出一体化拦截设备进行现场载体深度处理及拦截试验。研究了包埋硝化菌载体应用于污水深度处理的效果，考察了拦网和自清洗出水拦截装置的运行稳定性，有效解决了载体易流失、出水拦截装置易堵塞等问题。结果表明，常规水处理条件下包埋硝化菌载体对氨氮具有较好的去除能力，深度处理出水氨氮在1 mg/L以下，出水COD在30 mg/L以下，出水SS值小于10 mg/L。拦截设备具有高效拦截的能力，滚筒拦截设备运行可靠。

To promote engineering applications of the embedded microorganism carriers (EMC) technology in sewage treatment,an integrated interceptor is developed and used in the deep treatment of spot carriers and intercepting test,aiming to solve the problem that the effluent is easy to be blocked when the embedded carriers are applied in the engineering.The application effect of the embedded nitrobacteria carriers in the deep treatment of wastewater is studied,and the stabilities of the blocking network and self-cleaning water interceptor are investigated,which can solve effectively the problems such as the easy loss of carriers and the easy blockage of water interceptor.The results show that the embedding immobilized bacterium carrier has a good ability to remove ammonia nitrogen under conventional water treatment conditions.After deep treatment,the concentrations of ammonia nitrogen,COD and SS in effluent are below 1 mg·L^-1,30 mg·L^-1 and 10 mg·L^-1,respectively.The interceptor has an ability to intercept effectively,and the roller interceptor can run reliably.
