MBBR和LSP工艺在污水深度处理中的性能探究

指出了MBBR工艺和LSP工艺属于当前应用较多的新型水处理工艺。当将传统的好氧曝气池改造为MBBR工艺时,改造结果表明:COD降低30.8%,BOD 5降低42.8%,氨氮降低25.0%,总氮降低17.2%,SS降低57.9%,总磷降低26.7%;而LSP工艺通过形成复杂的微生物食物链,消耗剩余污泥量,实现对污泥的减量化处理。应用到改造工程中,产泥量降低67.5%,同时能够强化处理系统的生化功能,COD和BOD 5都有明显降低,分别降低了11.7%和12.1%。

Research on Performance of MBBR and LSP Processes in Advanced Sewage Treatment

The MBBR process and the LSP process are new water treatment processes that are currently widely used.When the traditional aerobic aeration tank is transformed into MBBR process,COD is reduced by 30.8%;BOD 5 is reduced by 42.8%;ammonia nitrogen is reduced by 25.0%;total nitrogen is reduced by 17.2%;SS is reduced by 57.9%,and total phosphorus is reduced by 26.7%.The LSP process can reduce the amount of sludge by forming a complex microbial food chain and consuming the remaining sludge.When applied to the renovation project,the mud output is reduced by 67.5%,and the biochemical function of the treatment system is strengthened at the same time.COD and BOD 5 is significantly reduced by 11.7%and 12.1%respectively.
